I saw a video in which a former special forces operator suggested filling a container in a stream with the mouth of the container facing downstream. That reduces the initial uptake of sediment, prior to pre-filtering which is crucial.
You are spot on. Also covering the mouth of the container with a bandana is a big bonus too
Some tips. Add a fine film of food grade silicone paste to the main O-ring. That alone made mine 10x easier to press which is one of the complaints with the Grayl. They sell food grade silicone in tiny tubes that will last years. For situations where you can't apply full body weight from above try leaning back and pressing it into your chest with both hands. I don't get leaks once the main O-ring is initially seated into the outer cup.
Awesome tip ! Thank you
Is food grade silicone another toxin? Won't it saturate the filter?
Great video. I absolutely love my Grayl filters! Best filter out there. I enjoy taking them with me to Colorado and drinking that crystal clear, ice cold mountain stream water!
I would add another step between these two - a hollow membrane. It's relatively cheap, light and compact and will reduce load on GRAYL carbon filter significantly.
Any half decent water filter has minimum of 3 step filtration and this is what should be done if you want most lifespan and effectiveness out of your filtration system.
If you've ever gotten sick off water the investment in new filters isn't bad. A lot faster than other other options.
Agreed. I think people should draw the distinction between water on the move and stationary water. Things like having time to boil when you set up camp or a big filter at a Bug out location. The grayl sits perfectly in the water on the moves section
Getting sick of dirty water is defin. an issue and replacing the filter is the best solution. Do you think that flushing the Grayl with diluted H2O2 after use and back at home, just to get rid of residual bacteria an prototozoe could be effektive? Do you additionally boil filtered water out of a used Grayl? Would be nice to hear from you, thanks.
I keep a small bottle of water with dissolved ALUM in it and mix 2 tablespoons in a 5gallon bucket of water and all the particulates sink to the bottom leaving me clean water to filter off the top…Alum is used by your municipalities water treatment plants to remove solids and particulates 👍
My tip for extending the life of your Grayl. Have a MSR Trailshot Micro with you as well.
@2:31 That's a nice millbank bag you designed for the Grayl UltraPress. In particular I like that it can nest your Grayl for storage. Too bad I didn't find one for sale on your website, I would have loved to add it to my own Grayl.
Thank you. Sadly, we had to stop selling on our site. Just a lack of time to be able to make sure it all ran smoothly.
You can find them at the bushcraft store in the UK or camp craft outdoors, stateside. If that helps
They sell them on Etsy
@@curttomlinson9337thanks for the pointer. My Grayl arrived today and I just ordered the millbank bag off etsy!
Thanks to your advice will try a replacement filter but mine locked up within 20 - 30 litres in a body of water frequently camp on, a lake in back country of Canada and later read instructions and Grayl does not advise using in tannin stained water which is most of the Northern Boreal here. My other filters work well over a good number of trips before losing filtration ability.
Your very welcome. Anything at all to help take those bits out is worth it. If it still gets hard to use after that I recommend returning the filter.
Simple solution is to use a sawyer filter before it goes in your grayl filter,
Sawyer filter is light and cheap and it will save your crayl filter and make it last many times longer
❤ I never thought of that.
A very good tip brother. I use sawyer a heap in the car and such. But as you can imagine this is a commissioned video by grayl.
The sawyer is also much better against cysts and Protozoa than the Grayl
@@seankelleher4222 yes but its ability for microplastics, heavy metals and blood born pathogens etc. is what does it for me. I dont agree there is one filter to rule them all. But there is horses for courses and when I am UL hiking in mountains the sawyer works just fine. For everything else I use the grayl.
@@inforestsandlands it does depend on what the risks are. 3 log removal of cysts and protozoa is inadequate in any source where they are a significant risk. And the amount of things like heavy metal that the Grayl will actually deal with is very uncertain. It’s main advantage is where viruses are a risk - but they can be dealt with by temperature pasturisation. It’s biggest problem though is that there is no genuine way of knowing when that cartridge has run out of umph.
Thank you for that nice and helpful video!
Very welcome ! 🤜🏼🤛🏼
I can't wait to get one and I'm going to get that blue bright blue and orange one so I don't lose it😂 this is an awesome video by the way Dave Canterbury talked about the same thing about (pre-filter) before you ( purify )
(filters for chunks)
( purifiers to make it clean to drink)
Great advice its such an easy step to over look
Thanks Mike. It's nice to talk to end users on the daily. Best way to keep improving something
Years ago on a 4day hike our filter stopped functioning both with in a pint or two US pint. Not going to name the company. This happened on the first day three of us three filters two down right off the bat . Returned those two filters bought a different one never have had a problem since. Yes it even had a pre filter on it. Had to boil our water after that. I’d say always have a backup and pre filter if possible. Thanks for the reminder’s
Great product and super presentation!
Thanks Eugenio 🤜🏼🔥🤛🏼 / joe
The grayl filter looks great. My only hesitation is that some areas we go into we've experianced heavy freezes overnight even in July or every monthbof the year. It happens sometimes. I worry what happens in heavy freezing temps.
A great question, and I ain't a spokesperson for grayl. I live in sweden, and the temps get pretty vicious. But I have a thick wool cozy for my one. In the viciously colder months (-30c) just strain and boil.
Nice one Joe. ATB
All the best brother 🤜🏼🔥🤛🏼
I carry a dedicated bandanna in my water kit specifically to pre-filter my water - no matter which filter system I’m using at the time…
Informative and beneficial video
Thank you Corley !
Killing it bro 🔥👍
Thanks my friend 🤜🏼🔥🤛🏼
That bookit looks like the world’s largest whoopee cushion.
Thanks for the recommendations. Can you share about your millbank bag you designed and showed for use with your Ultrapress (2:47)? Like the tight, small size. I would like to find one to fit the larger GeoPress as well. Thanks.
No problem. Are you stateside or Europe?
What, if any, are the differences between the orange and the black Geopress replacement filters?
To my knowledge there is no functional difference. The black models were simply made for people who bought the covert edition Geopress and didn't want the aesthetic ruined with a bright orange filter.
Just the color. I use them to help prevent mixing up new vs old filters.
If I'm using the grayl as an everyday water bottle because let's face it tap water is just as suspect as water in the wild, will I get more than the advertised presses or just the same
Just the same. It's more about what the various stages of the filter can handle or remove. Legally that's what can be said to he 99.99.99 percent safe.
24oz Geopress in almost daily use here in Arabia 🐪 Edited to add, you can also back flush the filter
Backflushing a Grayl may or may not be a great idea. It’s not designed for it. And even if it does unclog it a bit without damage it isn’t doing anything to restore the active carbon so may just be giving a false sense of security.
@@seankelleher4222 Have you ever replaced the filter? Asking for signs of degregation. I have a replacement but the original seems to do fine, despite the heavy use. I’ve relied on it now coming half-year.
@ it’s impossible to tell when the activated carbon is exhausted. That’s an intrinsic problem with activated carbon based systems. That’s why Grayl say to replace the cartridge after x many litres. If it’s been used heavily for 6 months it’s probably all used up and no longer removing pathogens.

@@seankelleher4222 Manufacturer website
“An UltraPress cartridge is rated for ~300 cycles (150 liters / 40 gallons); GeoPress cartridge for ~350 (250 liters / 65 gallons)”
I’m around 70 gallons minimum. Time to exchange the filter and keep an eye on the volume. Good timing, thanks.
Is it possible to take the filter out and securely close grayl Nalgene bottle to fill with hot water to use as a hot water bottle in your sleeping bag at night?
Great question and yes that is entirely possible. As always be careful of any bottle containing boiling water as seals can always go. As I have seen too many times haha
Thank you, breathing through your mouth is very damaging, filter water or not
?????
Should I be washing the Grayl in soapy water once per week and if so should I be washing the filter in it as well?
Wash with warm soapy water, by hand only, the container and never wash in any way the cartridge itself, the cartridge cannot be cleaned.
The filter can be rinsed well had set out to dry in a warm place for 3-4 days for long term storage between uses.
Always chech visually and smell rest for mold/mildew growth. Thats why a warm area with air flow is best, avoid cold, stagnent air and high humidity when drying.
Any chance you can direct me on where I can purchase that green ( I apologize for not knowing the name of it) green bag you use to carry water ?
Of course, brother. Its the Savotta water bucket.
@@inforestsandlands perfect, thank you for quick reply. Keep up with your content, I really enjoy learning from your videos.
Why is it not possible to back flush the Grayl filter? Is it just for the sake of replacement filter sales, or it actually impractical to do so? I’ve seen a video of someone using a jar inside their inner Grayl bottle to back flush their filter, but I don’t know how much it extends the useful life of it.
If your filter has the anti backflow silicon insert in it, it should be possible to remove it. Then fill clean cup with clean water while inserted and withdraw out from cup. Might take a few draws, but should backflush grayl if at all possible. Haven't tried it yet. Simple enough principle.
The one point however is I normally replace my carbon filters every 9-12 mths. with average use. Irregardless of ceramic filter conditions.
Am a zon just had geofilters on sale $23.00 so I picked up couple. I use Millbank bags and have a dozen various sawyer type/form filters which I add bag/tubing/refillable charcoal-filter canister to.
The Grayl is good for instant right now water supply. The bag system is a good camp/long term supply system where you have time to set up and treat water supply in volume.
ok then you get back home. do you let the filter dry out or throw it away and use a new one every time you go camping. ?
Let it dry out. Thoroughly dry cartridge by performing 1-2 'dry presses' (pressing without any water in the bottle) and empty excess water. Remove cartridge and allow it to air dry completely (depending on humidity it can take 2 - 4 days). Hand wash all other parts with warm, soapy water. Reassemble Grayl filter to create air tight seal for storage. Cartridges can last up to 3 years after opening if cared for properly between uses.
There are instructions with it that say you should dry it out for 1-4 days.
I filter the water before I put it in the bottle.
Best way to do it
Where can I get that bucket?
Variose types of collapsable buckets availible online, standard sources.
They go back to marine canvas buckets, but now use more modern designs and materials. And their fairly cheap and compact.
Where do I buy the filters by themselves?
If your based in Europe you can buy them from Astro Sweden , Scandinavian outdoors and Friluftsland. Amazon do also have them from time to time.
@@inforestsandlands Thank you! I could not find them anywhere!
Try thinking about baseball while you are purifying
haha " i should call her"
