Stephen you broke it down by volumetric cost! One of my favorite character traits you have is the abundance of over analysis. I’ve used the Grayl for a couple years now. It’s served me well in countries that are guaranteed to “flush your system” I found the weight issue can be easily counter by slipping the bottle into my wife’s bag. Cheers!
Great video, really helpful and practical comparison between the pros and cons of different filter types. Based on this review I bought the Pure Clear filter (500ml squeezable bottle) and when it arrived the instructions clearly state 'We recommend you change the filter every 2 months' - and again 'The filter cartridge has a lifespan of 200 litres or 2 months'. Nowhere on the website does it specify the '2 months' lifespan, which feels like deceptive marketing, because for most casual backpackers who go walking once or twice a month, a 200 litre lifespan is likely to last anywhere from 6 months to a year, whereas changing the filter every 2 months makes it a much more expensive proposition. In your video you state that the filter only has a lifespan of 2 months if it's left wet, but that lifespan increases if it's dried - and the website also states 'The life of the filter can be extended by drying out the filter and storing it after use' - but neither your review, nor the website give any indication of how much the lifespan is increased by storing it dry - which kinda matters. Is it by an extra month, 2 months, 6 months? Also the packaging which comes with the product makes no reference to the lifespan being increased beyond 2 months. The bottom line is - if I really have to change this every 2 months, then that takes the yearly cost to £90 just for filters (assuming I buy them in bulk, otherwise I'm also paying shipping) - which is nowhere near as cheap as is suggested in this review or on the website. And, if the lifespan can be increased by drying - by how much? Anyway, not a direct criticism of your review, more a note of caution for anyone else looking to buy this specific filter (I've emailed the company so will update here if I get a response) UPDATE - very helpful clarification from the manufacturer (and quick response!): 'To be crystal clear - the filter performs for around 220 litres, but for safety reasons we state 200 litres. The “change every 2 months” is based on usage of every day. You see some people find it hard to calculate how much they have used the filter when they use it every day. Our filters are in many different products, and some products are used every day (not sure a collapsible squeeze would be) but we offer this information as guidance. If someone is happy to calculate the exact usage, then its 200 litres. That 200 litres can be used in many ways such as 5 litres, then stored away for 1 year, then used the remainder of the 195litres, or just 10 litres in June, then stored, then used 20 litres in August etc etc, there is no limit on how you used your 200 litres. We would just recommend that the filter is stored correctly, which would be to dry out, placed in an airtight bag and stored in a dry place out of sunlight. Alternatively you can store it in the freezer.'
You make a good point. I do think this information should be clearer. Basically if you dry it out between uses it’ll last as long as it takes you to filter 200liters.
I think this is not true!!! There is activated charcoal in it and from day one you activate this charcoal, so the first use, mostly it is so that then one month later the working is not there any more or much less. Also not when you did filter just only 5 litre with it. Can you ask them? And does'nt it loose his electricity from the whole filter itself, tw motns later after used just 5 or 10 litere or so? Because this is how it works.
@@Dingeman-nonameYou’re correct that the activated carbon will remain activated (in truth it was activated from the moment it left the charcoal burner). We know a permanently wet filter has a shelf life of 2 months, so when dried, we can calculate the rate of activation because we know the density of air - it’s going to activate 816 times slower in air with 50% humidity. This extends its life to 1632 months or 136 years. If, in the example you were responding too, someone filtered 5L of water then stored the filter dry for 10 years, they don’t have 195L left, they have 175L left due to the degradation you refer too. Edit, they said 1 year, not 10, so they would in fact have 193 L of filtration left, not 195. You essentially lose 2L of filtration capacity per year. Of course anything that increases the molecule collision rate of air on the filter will increase this, if you store it on a warmer than 20C environment, you will lose more capacity, likewise if you have a higher humidity than 50%. If you live somewhere like the UK that tends to have high pressure atmospheric conditions sat over it, this will also have an effect, so to be safe, you could say 3L per year loss and be completely covered.
@@PippetWhippet From the moment the filter is activated with the use of water, the duration of its usability is only 2 months maximum, after 2 months the power of the carbon has worn off, whether you only filter 1 liter or 195 liters with it? So does the filter only last a maximum of 2 months from day 1 that you let water pass through it? In addition, it is written that if activated carbon is not (properly) sealed, it will not last long because it will absorb toxins from the air. Even if you have not activated it with water. So activated carbon also filters toxins from the air and there are extremely many giofen in the air, especially because of all the chemtrails that they spray over us day in and day out. And what does radiation from smartphones, WiFi, etc. do? There is virtually no greater poison than this and these rays disempower All Life and reverse life and its life force and thus also disempower and damage the activated carbon. This is what radiation and techniques from and in smartphones in particular do. So probebly also also with activated carbon.
A technical point for the geeks out there - filters which remove heavy metals and pesticide almost certainly do not do so by _filtration_- to have a filter so fine that it can remove metal ions (this is possible and is called reverse osmosis) requires a lot of pressure, far more than you could generate by squeezing a bag or sucking on the outlet. These contaminants are almost certainly removed by adsorption which partly explains the lower lifetime (volume treatable).
I was on a bushcraft course and mentioned to the instructor that my befree lets through the peaty water colour in the Peak District. He said if it's letting that through it's not filtering everything out and from the looks of what that does filter vs the Pure Clear it's a shocker. I've now ordered two conversion caps to fit my befree and CNOC bladders. Good to see a British company making some decent too.
Have Grayls for emergency kit bags/stationary camping. Have a collapsible silicone cup to uses with a lifestraw in my bicycling backpack bag =for day trip/areas with sketchy water supplies (in Wisconsin, we have some state parks that have drinking fountains connected to old iron hand pump/wells with extremely rusty pipes). Appreciate your information on the collapsible water bag options may look to purchase one of those as for day hikes!💧🥾
I have used the Lifestraw for years. I discovered the problem you pointed out while in my kayak. I had a small dry bag along so I used it to scoop up water then I sat upright and drank the water through the filter from the dry bag. From then on, I wrap my dry bag around my life straw filter and secure the rolled up bag with some rubber bands. Thanks for the video.
Good to know the new info. I still probably prefer sawyer with inline carbon filter. Its slower and slightly more bulk, but lasts much longer and the activated carbon can be replenished. Good to know this is an option if i was in some sort of race or just wanted to shave down to the slimmest pack.
Ahhhh!! I am so glad I stumbled across your video. I just recently purchased the Grayl and this video solidified I made the right choice for my travels!
I've just trialled the Pure Clear on a 25K hill race in the Mournes. Really hard to get a decent mouthful of water, had to suck and squeeze for 2-3secs to get enough. Not ideal when running over rough terrain. Interestingly, the Pure Clear lid and filter fit and seal onto my Salomon filter bottle. I used that combo as the Salomon is much easier to re-insert into running vest when refilling. In future, I'll use Salomon bottle/filter, but carry Pure Clear filter in case refilling from source I'm not too sure about.
I've just got a pure clear, it's much faster flow rate than my sawyer filters. It's far more convenient as well....and less expensive, it's a clear winner for me 👍🏻
I enjoyed the Gear Skeptic's water videos. They have a lot of information on the effectiveness of various filter methods based upon the certifications and scientific papers. Very understandable presentation of a difficult subject.
Great video stephen, got a question! is the grayl ultrapress a better version of the grayl geopress? i am thinking of buying ultrapress but just checking!! thanks again, you legend!
Regarding the Pure Clear filter, the filter itself looks nice, but I checked out all of the different containers and I don't like the materials they use. The hard bottles are Tritan plastic, the smaller soft squeeze bottles are TPU, and the bladders are ABS. All of these either leach significant amounts of hormone disruptor chemicals and/or add a definite taste to the water if water sits in it for any length of time. Would be nice to see some options in medical grade silicone (the least leaching of human made non metal container materials) or at the very least HDPE. I really can't stand the plasticky, chemically taste that a lot of plastic containers impart to water.
Thanks Stephen for this fantastic video, it answered all my questions.....well except one.....does the pouch of the pure clear give the water a plastic taste? I seem to be able to taste plastic from many type of bottle.
I don't know if it's because it's a newer product or what, but it looks like the pure clear filter in not available in the US. I only found it on a couple of weird sites that all had them for more than $80.
Great video, I have a GeoPress and an Ti GeoPress which are larger then the UltraPress. I've looked at the UltraPress and always wondered how the cap was attached and you showed that. I prefer the cap attached to avoid dropping it.
I'm trying to decide between a Pure Clear bottle and a Lifestraw bottle. Any suggestions? I love the video but I feel that beside your review Lifestraw difficulty to use you didn't touch on its filtration. Any thoughts? But in general your video is the only useful and most comprehensive one on travel water bottles with filter 👏🏻
One little known one missing... aquapure traveller from Pure Hydration, british company been around nearly 30 years, they also manufacture for and supply their products to the military. It's easy to use and effective against bacteria, protozoa, aswell as viruses and chemicals/metals. Also endorsed by the London hospital for tropical diseases and tge Liverpool school of tropical medicine.
Useful video, thanks. However, I do have a LifeStraw bottle which works similarly to the Grayl in that a bottle scoops up the water before the cap with the straw screws on. It has a 650ml capacity and the brand is Verstergaard. Obviously, it is heavier but it is a good bottle fur using at camp or on a bike.
The pure clean will be the slowest. I think it takes at least a full minute to refill one of my 500ml flasks. The Salomon fibre filter takes about 15seconds
Nice one, thank you. I'm Old School but not in any good way. Still setting off with loads of tap water and using chlorine tabs to eliminate any pleasure from drinking water collected on route. Going to get with the times.
Brilliant review Stephen, very informative 👍 Never really thought I'd have a need for a water filter with my camping requirements, but I have just picked up a cheap one from AliExpress 99% of my water consumption is in either tea or coffee, so boiling would take care of most of the nasties, but always thought it might be nice not to have bits of grit and other chewy things in my drink if I have to use something apart from tap water. Only tested once in our local brook so far, but it seems to do what I wanted it to do 😁 That PureClear one though looks excellent for anyone who needs a larger amount of good quality water, but is limited for space and weight.
I personally use the grayl geopress, i have a couple of them.. my problem with pretty much any other ive used is when you really pay attention to the water as you dip the containers (especially bag style), attached the filters (with the wet hands from the water source) and transfer the water, you tend to get loads of points where cross contamination can occur.. with the grayl i am far more able to control this, and personally have never seen any cross contamination..
At 09:25, you say the Solomon costs £ .045 or 4.5 pence, but the screen shows £. 45 or 45 pence, making it look three times the cost of the Pur, as opposed to 1/3 the cost. Otherwise, Great video and review!
I am really really interested to look into the Pure Clear, because a downside of fibre filters that was not mentioned is that the fibres (which are in fact tiny diameter tubes) can burst when allowed to freeze with water in them thus ruining the filter and letting lots of stuff through. Pure Clear looks like a single membrane. Would you care to comment @StephenJReid
Thanks for the video! I’m currently researching these types of filters for trail running (I have an MSR guardian for hiking). Given that all my runs🎉 are in the mountains in western Canada, I think I’ll go with the Salomon!
I've been using the sawyer squeeze for a number of years & I've been looking at the pure clear filter as the sawyer constantly gets blocked. Definitely going to swap after watching this, thanks very much 👍.
Thank you so much, I was looking for something with high filtration (semi rural area, farm land) but at a cost I could live with to Keep in an emergency bag. Found it!
I just purchased a Grayl bottle as I got a 20% off coupon and was able to get the titanium version that I can put on a campfire to heat the water as well. It's my 4th water filtration option. Why have so many? Depends on where I am going, how much I trust the water, etc. I also have a lifestraw in my BOB as it's so easy to just leave in there in the package at all times and guarantees that in an emergency if I forget to grab anything else I at least have something basic, even if it's not the preferable option. Sadly it looks like Pure Clear does not ship to America.
@@StephenJReidplease don’t compare the grayl and the pure as 1 is a purifier and other is a filter.your video failed the most basic of fact-checking.Both are totally different
Apologies if anyone's already asked this but have you (or anyone else reading this) tried any of the products from Water Well? They claim 100l per filter, and they do hard bottle and soft flask versions, they also claim filtering levels similar to the Gray, and appear to be cheaper than most other options. Not sure how long they've been about, can't really find any reviews for them
That was interesting Stephen. What do you think did the harm when you got sick? Chemicals from the trees or the fuel/lubs of the harvesting equipment? I have a Grayl and a Sawyer Squeeze and i nearly always go with the Sawyer because its smaller and I'm collecting water near source. I'm camping not running so i process about 2 litres in one go when i get to my location. I hang it in a tree and let gravity do the work. Grayl warn you about peat blocking the filter. Grayl is too big and bulky. The Sawyer can be put in a ziplock bag and put in your pocket and into your sleeping bag when its freezing. Couldnt sleep with a Grayl lol. I take the Grayl if I'm doing a bit of glamping with the wife because you never know about the plumbing and it is a "catch all". I definitely think I will buy one of those Pure Clear as it hits the sweet spot with quality water, weight and price. Thank you.
What is the difference in weight between the brands when filled with water rather than the difference when empty? This is the weight that matters, and it’s much less significant of a percentage difference when the bottles are full.
I had one, it’s a fibre filter. My problem with it was that the flow rate was worse than the Salomon filter and the thin plastic bottle/bag it came with has a tendency to burst, which mine did.
I’ve been wondering about these, perfect timing! About 15 years ago I spent an afternoon trailing around all the local outdoor shops with a friend buying up all the last iodine tablets before they were pulled from the shelves. He completely refuses to use chlorine tablets to this day 😅 How things have changed! Added reminiscing: Small dry bags were experimental stage too (but I still have mine from from 2009 trade shows 😁)
Great advancements, I’ve drank countless litres with my filter bottle on mountain runs. Including from a couple of suspect sources when a bit desperate
It is entirely different. It's only a hollow fiber filter like the Salomon in the video, so it only filters bacteria and protozoa, with no chemicals, viruses, or metals. Sawyer is the most common brand for hollow fibers, and it filters more water than Grayl. If you want an added level of water protection get some chlorine dioxide water purification tablets to protect against viruses. Chemicals and metals are rare in the backcountry unless you're near a factory or a more urban area.
Thanks for the recommendation Stephen. I’ve just got back from my hike in the lakes and I really liked using this pure clear filter. I usually flush my katadyn be free with water and a micropur tablet before I store it away. As this is a different type of filter do you do the same or just let it dry naturally without any flushing/cleaning before you store it in an air locked bag. Great bit of kit.
Does the Pure Clear has the same thread as the Salomon/Katadyn which are all the same, cause Hydrapak is the manufacturer for both. Would be nice if I could just buy the Filter/Screw Top and put it on my Flasks I already have.
Very good review, especially the environmental impact of the throwaway plastic bits. I’m in the market for a new filter, so if you survive a few more weeks after use,I’ll get one 🤣🤣
Does that filter fit a standard 40mm opening like the Salmon or the Katadyn BeFree? Wondering if it could be placed on other soft flasks like the CNOC.
Hi, thanks for the vid, I'm excited (how sad am I) to be getting the 1ltr Pure Clear for Christmas. Can I ask since you made this vid is the Pure Clear still your go to filter... Cheers, Gary
@@StephenJReid Yep but //titanium = light and since it is made of that it gives you the option of removing a number of items from your kit like a mess kit entirely. So it's more of a multi tool and comes with a cook pot lid.
Thanks. The lifespan is 200litres. So if you dry it out in between it’ll last years if not used loads. The 2 months is based on continuous usage. It’s confusing and I’ve told them they should change the wording. Personally I filter about 10litres max a month with mine so it’ll last about a couple of years for me.
One thing nice about the Grayl is it’s obviously more durable. What happens if the plastic bag of the others bust? Gayle also had a titanium model and you can use the outside container to boil water. Kinda expensive though.
0:20 ha ha You are a funny man...I really enjoy your reactions....I never knew there were so many different types of water filters! Thanks for this great comparison SirToday your videos are like science lessons..I love it it's easy to understand...I like it
Well put together video as usual. However I have some concerns around the tannins in water, in places like the Peak District. You are quite right, tannic water itself is not harmful, but apparently the tannins can damage the filters themselves. I have just been having a conversation with a representative of Grayl and they absolutely do not recommend using their filter with this kind of water. This is what they said "the problems with tannins is that they bind to the receptor sites intended to capture pathogens (bacteria, protozoa, virus)" "A Grayl should not be used with tannins at all. Even a single use in waters with such a high concentration puts you at a highly elevated risk since those receptor sites get blocked, there isn't anything to prevent the flow of pathogens through the filter." I was under the assumption that maybe the filter can still be used with this kind of water but it would just deteriorate quicker and that would be noticed by a slower flow rate and resulting in an early filter replacement. "as a representative of Grayl, I simply cannot instruct you to use your purifier in those conditions" Maybe they are just covering their backs and have to tread very carefully when it comes to something as life threatening as contaminated water. Also, When I asked how I could remove the tannins before filtering it they said this. "They really cannot be separated from a water source. Ironically, the best way to remove them is with the type of technology that Grayl uses" It seams that unless the water is running clear, the filters such as those in the Grayl are at risk of being compromised by the tannins present in that water and therefore you could be at risk of getting sick. Would love your thoughts on this.
hmmm I'll have to look into it. If it's true it makes the Grayl useless for at least a lot of Ireland & the UK as most upland areas here are peaty and will have tannins. I'll have to check with Pure Clear too
@ I thought I would look into it as we used a brand new Grayl a couple of years ago to filter water for 3 of us when hiking for 2 days in the Peak District. We didn’t get sick but by the end of the trip the filter was taking well over the recommended 25 second maximum to filter one cycle. It felt like 2-3 mins. It felt blocked. The water wasn’t full of sediment just discoloured (tannic) We certainly didn’t filter anywhere close to the amount of water they say it can cope with before a filter replacement is needed. That conversation I had today was with one representative, maybe some more formal clarification would help clear this up. Someone like yourself might be able to get that information. Thanks for your reply
i've been using the grayl for over 6 months since july.. almost every time i am out i use it. Its only problem is in the cold it is nearly impossible to get the cylinder out without rocking it in the cold. It has changed my entire out door experience. being able to get water as i need it is excellent. Clean clear water every time
@@StephenJReid The 500ml is to me a sign of what they were thinking making it. You have effectively a 4 hour system. For every two hours you need on average 500 ml. that means you have 500 ml at the car, then 500ml two hours later, and carry only the flask empty. the 500ml is the key , well as i see it. I have heard the system just slows down rather than fails. still testing mate, so the jury for me is still out until the unti has lived a life with me. I still only tap into water i trust.. or even pre boiled. if i'm out, for a camp i drink 50 percent boiled and 50 percent filtered, but for hiking... for me, the grayl is all i know of this stuff so far. its always interesting to read the comments on these topics. I just thought i'd let you know my experience. the worst was a cold day, cold hands, cold grayl, low strength, i could not budge it from the cylinder, i figured out that wiggling it was the way to go. The unit was empty and out in the wind chill for at least two hours. i did get it open though. but a challenge.
Great video as always! How is the pure clear filter holding up? What's flow rate like when trying to drink from the soft flask when it is upright in a trail vest? I am very tempted to get one but don't want it to be a nightmare to drink from, especially when on the move! Thanks.
It’s not fast to drink from. That’s the one downside. I’ve adapted by sipping from it regularly which works for me. But you’ll not be able to down a flask in a hurry.
@@StephenJReid thanks. Little and often is my approach when trail running anyways doesn’t sound like it would be a problem. Does it last for 200 litres or 2 months from first use, as I’ve heard conflicting reports about its lifespan?! Cheers, Louis
Have you tried the Hydroblu? Pls try that as well. I have had it since a few years, traveling over south east Asia, India and Srilanka, where most water sources are questionable (unless store bought). the filter portion of it is quite small and the water flow is quite good. If you have access to it, pls check it out. They give 1 spare filter with it as well. and I bought a pack of 5 filters along with it.
Both really interesting and very entertaining too. Surprised however that you didn't mention a Sawyer or Katadyn filter. I have a Sawyer which can be back flushed and claims a very very long lifetime. It is a 0.1 micron absolute filter and thus can easily take out bacteria and protozoa, but the pore size is not small enough to take out viruses - that makes the Pure Clear very interesting.
Well, instead of the Salomon you can use a Sawyer screw on filter (or clone thereof), which fits all standard bottle threads, is the same technology, can be reverse washed and also dried, costs same or less and is way more versatile. But the clear flask one looks very interesting.
Thanks for the info. I have the tabs for emergency but never used... bought the life straw but don't take it with me/never used😂 only thing I've done so far is boil water or melt snow!! But I've also only winter camped!
Can you use it longer then two monts if you did only filter 10 litres qater with it the first two monts? There is activated charcoal in it and I did read a lot of it and also this: When you first use this, so from day one where you activate this charcoal, so the first use, mostly it is so that then one month later the working is not there any more (or much much much less). Also not when you did filter just only 5 litre with it this first month. So is this also true with this Pure Clear water filter? And does'nt it loose his electricity from the whole filter itself, two monts later after used just 5 or 10 litre water or so? Because this is how it works is it? So is then the electricity or the electric magneticy?. So that the negative poisons do clamb on this magnetic electric loaded filter because the magneticy is gone after two o first use, so also if you did filter only 10 litres in this two monts?
I don't think they remove viruses, chemicals or heavy metals. Probably fine for upland use, but for lower down or near where people might be going to the toilet I'd want something more advanced
I‘ve been using the katadyn befree filter for several years. Never had any problems and the water tastes like the water source you filter. Just use clear small streams and you are good to go. Edit: After watching this I will get a Pure Clear filter for the lower areas with more man made contamination.
Yeah the fibre filters are great for higher areas. But definitely worth having something more robust lower down, we have bad problems here with farm runoff and pollution in most lowland rivers
I loved my Katadyn BeFree filters but I have never had one of the filters last longer than a trip or two. They clog, pretty much immediately. And yes, I store them dry and clean them when I get home...
@@AldenWeebstaJust got a lifestraw filter (think that’s similar to yours?) and the instructions actually say to store it with water in the bottle. Hope that helps.
It would be super cool if they made pre filter that can be screwed into the bottle when you scoop dirty water. Just some mesh to clean up most bigger particles.
That was superb Stephen, I've been using the Katadyn but on higher ground only, prior to this I also had the OG Lifestraw. Have to say that the Pure Clear is now a no brainer and even carry both based on the eight ratio.
Video was terrible. Compares the grayl which is a purifier to one is which is a filter. He makes no distinction. Grayl and pureclear are totally different
On the website "For every product purchased Pure Clear Filters provides 1400 litres of pure, clean and safe drinking water to those that need it most." They also come in 1000ml for longer hikes which is nice. Thanks for the video Stephen!
I managed windfarms on up land sites in NI. My projects specified drilling wells. Even on summits, irons, legionelala and Ecoli was always of the scales. No mission no thanks. I bring my own.
you contaminated the mout piece at 7.28 with your wet hands.. It is filtering the water from insides, but wath it left outside can leaks to where you put your mouth.
I’ve used the Katadyn BeFree since it came on the market and before that I used the Sawyer and Sawyer Mini. I’ve used these in Kentucky, Illinois, Michigan, Minnesota and Wisconsin (all heavily agricultural states) as well as mountain states like Colorado, South Dakota, Wyoming and Idaho, and I’ve never gotten sick or noticed a weird taste. Maybe our EPA does a better job of regulating agricultural runoff?
That’s possible, we have massive problems here in Northern Ireland. A lot of agri runoff and other pollution, it’s been warned about since the 70s and nothing has been done. Last summer there was a massive toxic algae bloom that turned entire lakes and rivers green and even contaminated beaches. Loads of dogs, swans and some other animals died and people got sick Regular fish kills from slurry too.
Its or 2 months so shy of 66 days. A bit shit and would love to see if that 200l holds up in water that actually needs filtering. Here its common sense to first use coffee filter on some lake waters so you dont kill larger hand pump filter too soon.
@@StephenJReidjust an FYI it’s virus filtration results were average at best with only a 2log reduction. Also there active water filter bottle comes from alibaba so identical to many many out there.
@@StephenJReid Their webpage say 1400. But my guess is that the carbon filter is good for 200L and the 1400 number is for bacteria and cysts with basically zero protection from virus. Similar to the grayl and many other carbon based filters
The grayl has some advantages. I will still buy the pure clear but the grayl has no contact between the clean spout and dirty water and this is vital for me. Then, I do not like to keep dirty water around, I’d have to filter water in a bottle.
Here in the US, the pure clear filter setup is SIGNIFICANTLY more expensive than the Grayl (by about $40). I've never seen anything from your side of the pond so outrageously marked up, especially since the US and UK have trade agreements in place - so I doubt it's any kind of tariff scheme adding to the price. But until they come down in price, I doubt you'll be seeing much adoption over here. Looks like an interesting product, though!
Love to see your review on Water-to-go. Bacteria, viruses heavy metals, 3 stage filtration and 2 filters around 20 quid (active bottle tho it’s squeezy)
Stephen you broke it down by volumetric cost! One of my favorite character traits you have is the abundance of over analysis.
I’ve used the Grayl for a couple years now. It’s served me well in countries that are guaranteed to “flush your system” I found the weight issue can be easily counter by slipping the bottle into my wife’s bag. Cheers!
😂 always good getting someone else to carry it
lolllll "babe can you hold this" and then proceeds to hike 5 miles
Great video, really helpful and practical comparison between the pros and cons of different filter types. Based on this review I bought the Pure Clear filter (500ml squeezable bottle) and when it arrived the instructions clearly state 'We recommend you change the filter every 2 months' - and again 'The filter cartridge has a lifespan of 200 litres or 2 months'. Nowhere on the website does it specify the '2 months' lifespan, which feels like deceptive marketing, because for most casual backpackers who go walking once or twice a month, a 200 litre lifespan is likely to last anywhere from 6 months to a year, whereas changing the filter every 2 months makes it a much more expensive proposition.
In your video you state that the filter only has a lifespan of 2 months if it's left wet, but that lifespan increases if it's dried - and the website also states 'The life of the filter can be extended by drying out the filter and storing it after use' - but neither your review, nor the website give any indication of how much the lifespan is increased by storing it dry - which kinda matters. Is it by an extra month, 2 months, 6 months? Also the packaging which comes with the product makes no reference to the lifespan being increased beyond 2 months.
The bottom line is - if I really have to change this every 2 months, then that takes the yearly cost to £90 just for filters (assuming I buy them in bulk, otherwise I'm also paying shipping) - which is nowhere near as cheap as is suggested in this review or on the website. And, if the lifespan can be increased by drying - by how much?
Anyway, not a direct criticism of your review, more a note of caution for anyone else looking to buy this specific filter (I've emailed the company so will update here if I get a response)
UPDATE - very helpful clarification from the manufacturer (and quick response!): 'To be crystal clear - the filter performs for around 220 litres, but for safety reasons we state 200 litres. The “change every 2 months” is based on usage of every day. You see some people find it hard to calculate how much they have used the filter when they use it every day. Our filters are in many different products, and some products are used every day (not sure a collapsible squeeze would be) but we offer this information as guidance.
If someone is happy to calculate the exact usage, then its 200 litres. That 200 litres can be used in many ways such as 5 litres, then stored away for 1 year, then used the remainder of the 195litres, or just 10 litres in June, then stored, then used 20 litres in August etc etc, there is no limit on how you used your 200 litres. We would just recommend that the filter is stored correctly, which would be to dry out, placed in an airtight bag and stored in a dry place out of sunlight. Alternatively you can store it in the freezer.'
You make a good point. I do think this information should be clearer. Basically if you dry it out between uses it’ll last as long as it takes you to filter 200liters.
Thanks for that additional information, it really was very helpful.
I think this is not true!!! There is activated charcoal in it and from day one you activate this charcoal, so the first use, mostly it is so that then one month later the working is not there any more or much less. Also not when you did filter just only 5 litre with it. Can you ask them? And does'nt it loose his electricity from the whole filter itself, tw motns later after used just 5 or 10 litere or so? Because this is how it works.
@@Dingeman-nonameYou’re correct that the activated carbon will remain activated (in truth it was activated from the moment it left the charcoal burner). We know a permanently wet filter has a shelf life of 2 months, so when dried, we can calculate the rate of activation because we know the density of air - it’s going to activate 816 times slower in air with 50% humidity. This extends its life to 1632 months or 136 years. If, in the example you were responding too, someone filtered 5L of water then stored the filter dry for 10 years, they don’t have 195L left, they have 175L left due to the degradation you refer too.
Edit, they said 1 year, not 10, so they would in fact have 193 L of filtration left, not 195.
You essentially lose 2L of filtration capacity per year. Of course anything that increases the molecule collision rate of air on the filter will increase this, if you store it on a warmer than 20C environment, you will lose more capacity, likewise if you have a higher humidity than 50%. If you live somewhere like the UK that tends to have high pressure atmospheric conditions sat over it, this will also have an effect, so to be safe, you could say 3L per year loss and be completely covered.
@@PippetWhippet From the moment the filter is activated with the use of water, the duration of its usability is only 2 months maximum, after 2 months the power of the carbon has worn off, whether you only filter 1 liter or 195 liters with it? So does the filter only last a maximum of 2 months from day 1 that you let water pass through it? In addition, it is written that if activated carbon is not (properly) sealed, it will not last long because it will absorb toxins from the air. Even if you have not activated it with water. So activated carbon also filters toxins from the air and there are extremely many giofen in the air, especially because of all the chemtrails that they spray over us day in and day out. And what does radiation from smartphones, WiFi, etc. do? There is virtually no greater poison than this and these rays disempower All Life and reverse life and its life force and thus also disempower and damage the activated carbon. This is what radiation and techniques from and in smartphones in particular do. So probebly also also with activated carbon.
A technical point for the geeks out there - filters which remove heavy metals and pesticide almost certainly do not do so by _filtration_- to have a filter so fine that it can remove metal ions (this is possible and is called reverse osmosis) requires a lot of pressure, far more than you could generate by squeezing a bag or sucking on the outlet. These contaminants are almost certainly removed by adsorption which partly explains the lower lifetime (volume treatable).
Stop obfuscating the issue with facts!
Your are confused between a filter and a purifier.Not all filters filter heavy metals.
I was on a bushcraft course and mentioned to the instructor that my befree lets through the peaty water colour in the Peak District. He said if it's letting that through it's not filtering everything out and from the looks of what that does filter vs the Pure Clear it's a shocker. I've now ordered two conversion caps to fit my befree and CNOC bladders. Good to see a British company making some decent too.
Yeah befree is just a fibre filter. Grand for higher places (if you don’t mind the flavour)
Sawyer is the only option. Much longer life and they donate all proceeds to helping undeveloped places around the world to get clean water.
One can fill a water bottle and suck clean water from it using a Life Straw. A person does not need to put the straw into the stream.
Only some of the life straws have this ability.
@mountaineer5596, He literally said exactly that in the video.
Have Grayls for emergency kit bags/stationary camping. Have a collapsible silicone cup to uses with a lifestraw in my bicycling backpack bag =for day trip/areas with sketchy water supplies (in Wisconsin, we have some state parks that have drinking fountains connected to old iron hand pump/wells with extremely rusty pipes). Appreciate your information on the collapsible water bag options may look to purchase one of those as for day hikes!💧🥾
Grayl has been a life saver
I have used the Lifestraw for years. I discovered the problem you pointed out while in my kayak. I had a small dry bag along so I used it to scoop up water then I sat upright and drank the water through the filter from the dry bag. From then on, I wrap my dry bag around my life straw filter and secure the rolled up bag with some rubber bands. Thanks for the video.
Good to know the new info. I still probably prefer sawyer with inline carbon filter. Its slower and slightly more bulk, but lasts much longer and the activated carbon can be replenished. Good to know this is an option if i was in some sort of race or just wanted to shave down to the slimmest pack.
Ahhhh!! I am so glad I stumbled across your video. I just recently purchased the Grayl and this video solidified I made the right choice for my travels!
I've just trialled the Pure Clear on a 25K hill race in the Mournes. Really hard to get a decent mouthful of water, had to suck and squeeze for 2-3secs to get enough. Not ideal when running over rough terrain. Interestingly, the Pure Clear lid and filter fit and seal onto my Salomon filter bottle. I used that combo as the Salomon is much easier to re-insert into running vest when refilling.
In future, I'll use Salomon bottle/filter, but carry Pure Clear filter in case refilling from source I'm not too sure about.
I've just got a pure clear, it's much faster flow rate than my sawyer filters. It's far more convenient as well....and less expensive, it's a clear winner for me 👍🏻
Is the Pure Clear system available out side UK?
Hi thank you. But the link does not lead to the pure clean. Where can I buy the pure clean water bottle and filter
I enjoyed the Gear Skeptic's water videos. They have a lot of information on the effectiveness of various filter methods based upon the certifications and scientific papers. Very understandable presentation of a difficult subject.
I went for the pure clean. Thank you so much for this informative video
Great video stephen, got a question!
is the grayl ultrapress a better version of the grayl geopress?
i am thinking of buying ultrapress but just checking!!
thanks again, you legend!
Regarding the Pure Clear filter, the filter itself looks nice, but I checked out all of the different containers and I don't like the materials they use. The hard bottles are Tritan plastic, the smaller soft squeeze bottles are TPU, and the bladders are ABS. All of these either leach significant amounts of hormone disruptor chemicals and/or add a definite taste to the water if water sits in it for any length of time.
Would be nice to see some options in medical grade silicone (the least leaching of human made non metal container materials) or at the very least HDPE. I really can't stand the plasticky, chemically taste that a lot of plastic containers impart to water.
You can try using a sheep's bladder, with a metal straw, that should be perfectly organic enough for you.
Tank you, you say this! This is very, very important! Thanks!
Thanks Stephen for this fantastic video, it answered all my questions.....well except one.....does the pouch of the pure clear give the water a plastic taste? I seem to be able to taste plastic from many type of bottle.
I don't know if it's because it's a newer product or what, but it looks like the pure clear filter in not available in the US. I only found it on a couple of weird sites that all had them for more than $80.
Chase3141 what websites did you find it on out of interest?
Great video, I have a GeoPress and an Ti GeoPress which are larger then the UltraPress. I've looked at the UltraPress and always wondered how the cap was attached and you showed that. I prefer the cap attached to avoid dropping it.
I'm trying to decide between a Pure Clear bottle and a Lifestraw bottle. Any suggestions? I love the video but I feel that beside your review Lifestraw difficulty to use you didn't touch on its filtration. Any thoughts? But in general your video is the only useful and most comprehensive one on travel water bottles with filter 👏🏻
One little known one missing... aquapure traveller from Pure Hydration, british company been around nearly 30 years, they also manufacture for and supply their products to the military. It's easy to use and effective against bacteria, protozoa, aswell as viruses and chemicals/metals. Also endorsed by the London hospital for tropical diseases and tge Liverpool school of tropical medicine.
Useful video, thanks. However, I do have a LifeStraw bottle which works similarly to the Grayl in that a bottle scoops up the water before the cap with the straw screws on. It has a 650ml capacity and the brand is Verstergaard. Obviously, it is heavier but it is a good bottle fur using at camp or on a bike.
If using to fill up a 2L hydration bladder how long do you think the two soft flasks take? Which one packs down smaller?
The pure clean will be the slowest. I think it takes at least a full minute to refill one of my 500ml flasks. The Salomon fibre filter takes about 15seconds
Nice one, thank you. I'm Old School but not in any good way. Still setting off with loads of tap water and using chlorine tabs to eliminate any pleasure from drinking water collected on route. Going to get with the times.
Filters like this are game changing for me. I rarely carry anymore than 500ml at a time now
Brilliant review Stephen, very informative 👍
Never really thought I'd have a need for a water filter with my camping requirements, but I have just picked up a cheap one from AliExpress
99% of my water consumption is in either tea or coffee, so boiling would take care of most of the nasties, but always thought it might be nice not to have bits of grit and other chewy things in my drink if I have to use something apart from tap water.
Only tested once in our local brook so far, but it seems to do what I wanted it to do 😁
That PureClear one though looks excellent for anyone who needs a larger amount of good quality water, but is limited for space and weight.
No one ever wants to chew their tea 🤢
I personally use the grayl geopress, i have a couple of them.. my problem with pretty much any other ive used is when you really pay attention to the water as you dip the containers (especially bag style), attached the filters (with the wet hands from the water source) and transfer the water, you tend to get loads of points where cross contamination can occur.. with the grayl i am far more able to control this, and personally have never seen any cross contamination..
At 09:25, you say the Solomon costs £ .045 or 4.5 pence, but the screen shows £. 45 or 45 pence, making it look three times the cost of the Pur, as opposed to 1/3 the cost.
Otherwise, Great video and review!
I am really really interested to look into the Pure Clear, because a downside of fibre filters that was not mentioned is that the fibres (which are in fact tiny diameter tubes) can burst when allowed to freeze with water in them thus ruining the filter and letting lots of stuff through. Pure Clear looks like a single membrane. Would you care to comment @StephenJReid
I liked the t.p.
flying in the air.
Funny, Stephen.
Great video.
Thanks for the video! I’m currently researching these types of filters for trail running (I have an MSR guardian for hiking). Given that all my runs🎉 are in the mountains in western Canada, I think I’ll go with the Salomon!
This was a really good video. Thanks
I've been using the sawyer squeeze for a number of years & I've been looking at the pure clear filter as the sawyer constantly gets blocked. Definitely going to swap after watching this, thanks very much 👍.
Thank you so much, I was looking for something with high filtration (semi rural area, farm land) but at a cost I could live with to Keep in an emergency bag. Found it!
What about the Sawyer Squeeze? Apparently it’s popular with through hikers.
Used this for years. You can backflush when it gets clogged.
I just purchased a Grayl bottle as I got a 20% off coupon and was able to get the titanium version that I can put on a campfire to heat the water as well. It's my 4th water filtration option. Why have so many? Depends on where I am going, how much I trust the water, etc. I also have a lifestraw in my BOB as it's so easy to just leave in there in the package at all times and guarantees that in an emergency if I forget to grab anything else I at least have something basic, even if it's not the preferable option.
Sadly it looks like Pure Clear does not ship to America.
Yeah I have these 3 filters I’ll use for different things. I saw the titanium Grayl, expensive but a cool bit of kit
@@StephenJReidplease don’t compare the grayl and the pure as 1 is a purifier and other is a filter.your video failed the most basic of fact-checking.Both are totally different
They ship to America now.
@@chefgav1but in the end they both do the same thing for you
Do you know whether the Pure Clear filter bottle will be available from US storefronts?
They're shipping to the states now!
Apologies if anyone's already asked this but have you (or anyone else reading this) tried any of the products from Water Well? They claim 100l per filter, and they do hard bottle and soft flask versions, they also claim filtering levels similar to the Gray, and appear to be cheaper than most other options. Not sure how long they've been about, can't really find any reviews for them
Thank you! Off the back of your review I purchased the 1 litre pure clear. I use a bladder but will carry as a backup
That was interesting Stephen. What do you think did the harm when you got sick? Chemicals from the trees or the fuel/lubs of the harvesting equipment?
I have a Grayl and a Sawyer Squeeze and i nearly always go with the Sawyer because its smaller and I'm collecting water near source.
I'm camping not running so i process about 2 litres in one go when i get to my location. I hang it in a tree and let gravity do the work.
Grayl warn you about peat blocking the filter. Grayl is too big and bulky. The Sawyer can be put in a ziplock bag and put in your pocket and into your sleeping bag when its freezing. Couldnt sleep with a Grayl lol.
I take the Grayl if I'm doing a bit of glamping with the wife because you never know about the plumbing and it is a "catch all".
I definitely think I will buy one of those Pure Clear as it hits the sweet spot with quality water, weight and price. Thank you.
What is the difference in weight between the brands when filled with water rather than the difference when empty? This is the weight that matters, and it’s much less significant of a percentage difference when the bottles are full.
What about the sawyer mini
I had one, it’s a fibre filter. My problem with it was that the flow rate was worse than the Salomon filter and the thin plastic bottle/bag it came with has a tendency to burst, which mine did.
Sawyer squeeze would be better than the mini for flow rate. Pair it with a CNOC bag and ditch the crappy bag it came with
I’ve been wondering about these, perfect timing!
About 15 years ago I spent an afternoon trailing around all the local outdoor shops with a friend buying up all the last iodine tablets before they were pulled from the shelves.
He completely refuses to use chlorine tablets to this day 😅
How things have changed!
Added reminiscing: Small dry bags were experimental stage too (but I still have mine from from 2009 trade shows 😁)
Great advancements, I’ve drank countless litres with my filter bottle on mountain runs. Including from a couple of suspect sources when a bit desperate
@@StephenJReid Chocolate sheep drops are usually my biggest concern in my area so good to know!
Does the grail have a 100% metal version? I don't want any plastics. thanks :)
How does the sawyer compare with the grayl? Sawyer has like 100k liters
It is entirely different. It's only a hollow fiber filter like the Salomon in the video, so it only filters bacteria and protozoa, with no chemicals, viruses, or metals. Sawyer is the most common brand for hollow fibers, and it filters more water than Grayl. If you want an added level of water protection get some chlorine dioxide water purification tablets to protect against viruses. Chemicals and metals are rare in the backcountry unless you're near a factory or a more urban area.
Cheers for this. I need a water filter and i didnt know where to start. Pureclear seems the best option for me.
Thanks Sam
Can’t find the pure clear in the states 😞
Thanks for the recommendation Stephen. I’ve just got back from my hike in the lakes and I really liked using this pure clear filter. I usually flush my katadyn be free with water and a micropur tablet before I store it away. As this is a different type of filter do you do the same or just let it dry naturally without any flushing/cleaning before you store it in an air locked bag. Great bit of kit.
I just rinse it out, disassemble and leave to dry between uses
@@StephenJReid Top man. Thank you Stephen
Does the Pure Clear has the same thread as the Salomon/Katadyn which are all the same, cause Hydrapak is the manufacturer for both. Would be nice if I could just buy the Filter/Screw Top and put it on my Flasks I already have.
Yeah 40mm
Thanks Stephen, is the the Pure Filter interchangeable with a Salomon soft flask - i.e. same thread?
Yes it is, its a 42mm cap lid which is the same thread as the Salomon, Katadyn and the Life Straw Soft Flask
Is the slower filter speed of the pure clean close to the same rate as the Kayden?
Very good review, especially the environmental impact of the throwaway plastic bits. I’m in the market for a new filter, so if you survive a few more weeks after use,I’ll get one 🤣🤣
Used it a few more times and no diarrhoea so far 😂
Review was terrible. Doesn’t understand the difference between a filter and a purifier
Hi, have you considered the Water-to-Go bottles? They filter viruses and heavy metals too, with cheap replacement filters.
That list sounds like stuff we can also find in normal tap water 😅
I'm still looking for a good affordable one as an emergency back to have at home.
if u want anything for just home, straw should be enough imho.
Does that filter fit a standard 40mm opening like the Salmon or the Katadyn BeFree? Wondering if it could be placed on other soft flasks like the CNOC.
Hi, thanks for the vid, I'm excited (how sad am I) to be getting the 1ltr Pure Clear for Christmas. Can I ask since you made this vid is the Pure Clear still your go to filter... Cheers, Gary
Grayal has a titanium version that you can use for cooking/boiling too and it's lighter than the original.
Costs near £200 though 😱 does look cool
@@StephenJReid Yep but //titanium = light and since it is made of that it gives you the option of removing a number of items from your kit like a mess kit entirely. So it's more of a multi tool and comes with a cook pot lid.
Great review Stephen, been interested in the pure clear filters for a while. So is the life span 200 litres of usage or 2 months time period? Atb
Thanks. The lifespan is 200litres. So if you dry it out in between it’ll last years if not used loads.
The 2 months is based on continuous usage. It’s confusing and I’ve told them they should change the wording.
Personally I filter about 10litres max a month with mine so it’ll last about a couple of years for me.
@@StephenJReid that’s good to hear, I’ve the be free but looking for protection now the hills are getting busier. Thanks for getting back to me
One thing nice about the Grayl is it’s obviously more durable. What happens if the plastic bag of the others bust? Gayle also had a titanium model and you can use the outside container to boil water. Kinda expensive though.
0:20 ha ha You are a funny man...I really enjoy your reactions....I never knew there were so many different types of water filters! Thanks for this great comparison SirToday your videos are like science lessons..I love it it's easy to understand...I like it
Thanks Ajay 🙂
@@StephenJReid you are welcome Sir
Really good review - I currently have a Katadyn, and will be getting the Pure Clear - thanks for making the choice easy for me :)
No problem, glad you found this useful
Avoid as its 2log virus results are average at best.
I'm sorry, what?@@chefgav1
Would you be willing to do befree vs pure clear?
Befree is a fibre filter so same as the Salomon one I showed here
Well put together video as usual. However I have some concerns around the tannins in water, in places like the Peak District. You are quite right, tannic water itself is not harmful, but apparently the tannins can damage the filters themselves. I have just been having a conversation with a representative of Grayl and they absolutely do not recommend using their filter with this kind of water.
This is what they said
"the problems with tannins is that they bind to the receptor sites intended to capture pathogens (bacteria, protozoa, virus)"
"A Grayl should not be used with tannins at all. Even a single use in waters with such a high concentration puts you at a highly elevated risk
since those receptor sites get blocked, there isn't anything to prevent the flow of pathogens through the filter."
I was under the assumption that maybe the filter can still be used with this kind of water but it would just deteriorate quicker and that would be noticed by a slower flow rate and resulting in an early filter replacement.
"as a representative of Grayl, I simply cannot instruct you to use your purifier in those conditions"
Maybe they are just covering their backs and have to tread very carefully when it comes to something as life threatening as contaminated water.
Also, When I asked how I could remove the tannins before filtering it they said this. "They really cannot be separated from a water source. Ironically, the best way to remove them is with the type of technology that Grayl uses"
It seams that unless the water is running clear, the filters such as those in the Grayl are at risk of being compromised by the tannins present in that water and therefore you could be at risk of getting sick.
Would love your thoughts on this.
hmmm I'll have to look into it. If it's true it makes the Grayl useless for at least a lot of Ireland & the UK as most upland areas here are peaty and will have tannins. I'll have to check with Pure Clear too
@ I thought I would look into it as we used a brand new Grayl a couple of years ago to filter water for 3 of us when hiking for 2 days in the Peak District. We didn’t get sick but by the end of the trip the filter was taking well over the recommended 25 second maximum to filter one cycle. It felt like 2-3 mins. It felt blocked. The water wasn’t full of sediment just discoloured (tannic) We certainly didn’t filter anywhere close to the amount of water they say it can cope with before a filter replacement is needed.
That conversation I had today was with one representative, maybe some more formal clarification would help clear this up. Someone like yourself might be able to get that information.
Thanks for your reply
i've been using the grayl for over 6 months since july.. almost every time i am out i use it.
Its only problem is in the cold it is nearly impossible to get the cylinder out without rocking it in the cold. It has changed my entire out door experience. being able to get water as i need it is excellent.
Clean clear water every time
Grayl is a brilliant bit of kit if you don’t mind the weight. I suppose it does save you having to carry extra water so for still weight savings
@@StephenJReid
The 500ml is to me a sign of what they were thinking making it.
You have effectively a 4 hour system. For every two hours you need on average 500 ml.
that means you have 500 ml at the car, then 500ml two hours later, and carry only the flask empty. the 500ml is the key , well as i see it.
I have heard the system just slows down rather than fails. still testing mate, so the jury for me is still out until the unti has lived a life with me. I still only tap into water i trust.. or even pre boiled. if i'm out, for a camp i drink 50 percent boiled and 50 percent filtered, but for hiking... for me, the grayl is all i know of this stuff so far. its always interesting to read the comments on these topics.
I just thought i'd let you know my experience.
the worst was a cold day, cold hands, cold grayl, low strength, i could not budge it from the cylinder, i figured out that wiggling it was the way to go. The unit was empty and out in the wind chill for at least two hours.
i did get it open though. but a challenge.
@@lifesahobby That's good to know, I haven used mine on a really cold day yet
I was very Interested but sadly they do not ship to Switzerland or Germany. But I will keep a eye out tanks for the video.
yeah they are quite new and a small brand so mostly shipping to the Uk for now unfortunately .
Real and informative video thank you!
Great video as always! How is the pure clear filter holding up? What's flow rate like when trying to drink from the soft flask when it is upright in a trail vest? I am very tempted to get one but don't want it to be a nightmare to drink from, especially when on the move! Thanks.
It’s not fast to drink from. That’s the one downside. I’ve adapted by sipping from it regularly which works for me. But you’ll not be able to down a flask in a hurry.
@@StephenJReid thanks. Little and often is my approach when trail running anyways doesn’t sound like it would be a problem. Does it last for 200 litres or 2 months from first use, as I’ve heard conflicting reports about its lifespan?! Cheers, Louis
Have you tried the Hydroblu? Pls try that as well. I have had it since a few years, traveling over south east Asia, India and Srilanka, where most water sources are questionable (unless store bought). the filter portion of it is quite small and the water flow is quite good. If you have access to it, pls check it out. They give 1 spare filter with it as well. and I bought a pack of 5 filters along with it.
pure Clear is UK only?
Currently yes
New subscriber here thanks for doing this video, lots of practical advice and information on water filter for hiking!
Both really interesting and very entertaining too. Surprised however that you didn't mention a Sawyer or Katadyn filter. I have a Sawyer which can be back flushed and claims a very very long lifetime. It is a 0.1 micron absolute filter and thus can easily take out bacteria and protozoa, but the pore size is not small enough to take out viruses - that makes the Pure Clear very interesting.
Liked and sub'd
Well, instead of the Salomon you can use a Sawyer screw on filter (or clone thereof), which fits all standard bottle threads, is the same technology, can be reverse washed and also dried, costs same or less and is way more versatile.
But the clear flask one looks very interesting.
Btw, which would be an actual filter instead of a bottle with integrated filter.
are you using a Sony camera?
Great Video and insight. The Pure Clear seems the best choice for me and I'll be popping it on my list of things to get.
Thanks
Glad it was useful Bruce!
Thanks for the info. I have the tabs for emergency but never used... bought the life straw but don't take it with me/never used😂 only thing I've done so far is boil water or melt snow!! But I've also only winter camped!
Thanks for all the information!!!
This video is quite perfect
I didn't know about the Pure Clear! A wonderful discovery for me hahahaha
The breakdown of full costs, post inital purchase was so helpful. I've been trying to figure this out and decide which to buy for days. Thank you!!!
Nicely put together. Best wishes out there. Been a wet one!
Can you use it longer then two monts if you did only filter 10 litres qater with it the first two monts? There is activated charcoal in it and I did read a lot of it and also this: When you first use this, so from day one where you activate this charcoal, so the first use, mostly it is so that then one month later the working is not there any more (or much much much less). Also not when you did filter just only 5 litre with it this first month. So is this also true with this Pure Clear water filter? And does'nt it loose his electricity from the whole filter itself, two monts later after used just 5 or 10 litre water or so? Because this is how it works is it? So is then the electricity or the electric magneticy?. So that the negative poisons do clamb on this magnetic electric loaded filter because the magneticy is gone after two o first use, so also if you did filter only 10 litres in this two monts?
What are your thoughts on the Lifestraw Go bottles?
I don't think they remove viruses, chemicals or heavy metals. Probably fine for upland use, but for lower down or near where people might be going to the toilet I'd want something more advanced
Excellent video. I just bought three collapsible filters.
I‘ve been using the katadyn befree filter for several years. Never had any problems and the water tastes like the water source you filter. Just use clear small streams and you are good to go.
Edit: After watching this I will get a Pure Clear filter for the lower areas with more man made contamination.
Yeah the fibre filters are great for higher areas. But definitely worth having something more robust lower down, we have bad problems here with farm runoff and pollution in most lowland rivers
I loved my Katadyn BeFree filters but I have never had one of the filters last longer than a trip or two. They clog, pretty much immediately. And yes, I store them dry and clean them when I get home...
@@AldenWeebstaJust got a lifestraw filter (think that’s similar to
yours?) and the instructions actually say to store it with water in the bottle. Hope that helps.
I got very ill after using the katadyn be free! I'm definitely not using it again without adding a chlorine tablet
It would be super cool if they made pre filter that can be screwed into the bottle when you scoop dirty water. Just some mesh to clean up most bigger particles.
Hi stephen were was clip at 4.23 filmed your talking about Bann looks familiar
Lough Beg
Yip my back yard
the soft ones are handy, but its easy to make holes, rip it etc. also, microplastics.
That was superb Stephen, I've been using the Katadyn but on higher ground only, prior to this I also had the OG Lifestraw. Have to say that the Pure Clear is now a no brainer and even carry both based on the eight ratio.
That’s a good shout, could easily carry the pure Clear and the Salomon/katadyn for less than 200grams and benefits of all
Video was terrible. Compares the grayl which is a purifier to one is which is a filter. He makes no distinction. Grayl and pureclear are totally different
What is your opinion on the Lifesaver bottle 🤔
your Pure Clear link doesn't work from the US
Unfortunately not, they are a small company and not set up for US sales yet
On the website "For every product purchased Pure Clear Filters provides 1400 litres of pure, clean and safe drinking water to those that need it most." They also come in 1000ml for longer hikes which is nice. Thanks for the video Stephen!
They donate to a water charity with every purchase to provide 1400 litres to people without access to clean water
Stephen! Loved this :) thank you! Could you review ozone water filters?
The pure clear looks the same kind of flow rate as the Sawyer mini.
I use the befree and normal Sawyer squeeze. I use knoc soft water bottles.
Yeah similar to sawyer flow except this filters out a LOT more than the sawyer. The sawyer is a fibre filter I think
I managed windfarms on up land sites in NI. My projects specified drilling wells. Even on summits, irons, legionelala and Ecoli was always of the scales. No mission no thanks. I bring my own.
you contaminated the mout piece at 7.28 with your wet hands..
It is filtering the water from insides, but wath it left outside can leaks to where you put your mouth.
I’ve used the Katadyn BeFree since it came on the market and before that I used the Sawyer and Sawyer Mini. I’ve used these in Kentucky, Illinois, Michigan, Minnesota and Wisconsin (all heavily agricultural states) as well as mountain states like Colorado, South Dakota, Wyoming and Idaho, and I’ve never gotten sick or noticed a weird taste. Maybe our EPA does a better job of regulating agricultural runoff?
That’s possible, we have massive problems here in Northern Ireland. A lot of agri runoff and other pollution, it’s been warned about since the 70s and nothing has been done.
Last summer there was a massive toxic algae bloom that turned entire lakes and rivers green and even contaminated beaches. Loads of dogs, swans and some other animals died and people got sick
Regular fish kills from slurry too.
The Pure Clear looks like the winner. Lightweight, affordable, purifies everything. 200 liters is 3 liters a day for 66 days.
It’s 200 litres though. Where did you get 1400?
Its or 2 months so shy of 66 days. A bit shit and would love to see if that 200l holds up in water that actually needs filtering. Here its common sense to first use coffee filter on some lake waters so you dont kill larger hand pump filter too soon.
@@StephenJReidjust an FYI it’s virus filtration results were average at best with only a 2log reduction. Also there active water filter bottle comes from alibaba so identical to many many out there.
@@StephenJReid Their webpage say 1400. But my guess is that the carbon filter is good for 200L and the 1400 number is for bacteria and cysts with basically zero protection from virus. Similar to the grayl and many other carbon based filters
The grayl has some advantages. I will still buy the pure clear but the grayl has no contact between the clean spout and dirty water and this is vital for me. Then, I do not like to keep dirty water around, I’d have to filter water in a bottle.
Interesting vid cheers Stephen! Thought about doing a similar one myself as I have several different filters. The clear blue looks good! 👍
Thanks! I get asked about filters all the time so thought I should finally just make a video.
@@StephenJReid haha just realised I put clear blue which is a pregnancy test 🤣🤣🤣🤣🤣
Here in the US, the pure clear filter setup is SIGNIFICANTLY more expensive than the Grayl (by about $40). I've never seen anything from your side of the pond so outrageously marked up, especially since the US and UK have trade agreements in place - so I doubt it's any kind of tariff scheme adding to the price. But until they come down in price, I doubt you'll be seeing much adoption over here. Looks like an interesting product, though!
Where are you seeing it for sale? There have been a few places buying and reselling them at high markup. I don’t think they officially sell to US yet
@@StephenJReid ah, that explains it. It did seem like a disreputable site, now that I think of it.
Love to see your review on Water-to-go. Bacteria, viruses heavy metals, 3 stage filtration and 2 filters around 20 quid (active bottle tho it’s squeezy)
