Dave is still the go to for good information after all these years. Thank you.
OK brother when you’re ready to start selling that new add-on for your filtering system, please let us know. I will definitely be getting me one. I absolutely love all of the self-reliance outfitter products. Thank you Dave Canterbury.
This is exactly why Dave is the #1 survival instructor on UA-cam. No one else is as generous as he is with sharing information!
Thanks, Dave! I can’t express enough my gratitude for all you have shared with the community for free over the years. These complete lessons set you way above the rest. 🙏
Water filtering, disinfection and purification master class! Very comprehensive and excellent work as always. After all of that, it still brings me back to the Grayl as the best overall in my mind. It is a bit awkward to carry and has limited capacity per cycle but for a solo application and combined with the PF stainless cup and Millbank bag, it’s a gem and hard to beat.
Thanks for being nonbiased with your pros & cons, and for covering all the bases of what we need to keep in mind. It's also great that you can impart the experience of your actual hours and hours of dirt time testing various products.
Pretty eye opening regarding the stuff that doesn’t kill giardia. That’s high on my priority list to get rid of. Especially in a survival situation.
You left off radiation and other special hazards. Great class Dave, thanks for all that you do sir.
Exactly why I love my Grayl's. Weight doesn't bother me knowing I have purified Water where ever I am. Damn fine Info .
don't let wet filters freeze , , , ,will break membranes
Wow!! Brother!! Thank you so much!! I’ve been looking for this type of video for a long time!! I did buy the grayl that you sell, thank you for sharing this extra detail!! You’re amazing my traveling brother!!! Always facing the East!!
Ive experimented with myriad devices to treat water over several decades.
Since investing in a Grayl Geopress a few years back, I've got rid of most of my other filters/purifiers.
The Grayl is hands-down the best system I've come across for effectiveness and ease of use.
Owing to this, I'm happy to carry the extra weight it entails.
And regardless of boiling or purifying, I always carry a Millbank bag to combat turbidity.
A significant hazard that you haven't covered of suspended systems like the Sawyer is that, at the same time as clean water is collecting in your receiving container, so is contaminated water that is running down the exterior of the collection bag and over the filter.
For me, this is a major design flaw. Consequently, I have always stayed well clear of this type of filter system.
You're new bespoke 3D printed bottle caps are a great addition as they will eradicate the above problem.
For anyone using such a suspended filter into an open necked bottle, beware! You're running the risk of still drinking contaminated water.
Fantastic Dave! Very helpful!
Very informative. In my experience where a person is located and the season a person is out, freezing temperatures is another detail you should consider when choosing your water collection system.
Steam Distillation works for everything. . .even when contaminated by radioactive isotopes.
Great discussion. The blackboard presentation is worth remembering. Thanks!
THAT wuz one 'ell of a Safe Water 101 short course! TY soooo much for posting. I've always had the Sawyer, now I need to rethink it.
I shared u out on the texas news studio , twitch platform ml.and fam as well great job Dave!!!
Good information but the sources are surface water. Ground water is spring,shallow and deep well. I work as a licensed ground water op for an industrial facility. So I have testing equipment at my work area . The grayl is by far the best way to filter water .
Dave will always and forever be the G.O.A.T. when it comes to survival, and teaching it in a plain and simple, easy to learn fashion. We all owe him a thank you for that, and his service in our military 🇺🇸🫡
VERY helpful, clear, concise info. Thank you, Dave. I've just ordered a Grayl to give me "3 is better"...
Cheers!
Phenomenal video! This was exactly the information I've been looking for. Thanks Dave!
The sawyer squeeze is by far the best filter on the market and is well proven even in 3rd world countries where the water is absolutely filthy. Sawyer also donates loads of filter supplies to 3r world countries and this has significantly reduced water borne illnesses in these areas. Never a full guarantee but sawyer is going to give you a safe drink of water.
When I build my "Emergency Bag" , I take from Thru Hikers, Bushcrafters and Dave Canterbury. This is the info I learn from experts like Dave.
Great info, thank you Dave!
Best video on UA-cam!
This was an awesome information packed video! I learned so much!! Thank you👍
Great video and thanks!
Excellent presentation, thank you for sharing your knowledge.
Comprehensive!!!! Very nice.
So glad to see you still uploading videos. Thank you for all that you do Dave. God bless!
Great overview Dave. Thanks for putting this together.
Awesome video as always Dave! That was a LOT of great information and definitely worth watching again!
I appreciate all you do Dave. So grateful. Thank you
Excellent presentation. Bravo.
Great video Dave
This is great. Thank you
Thanks Dave
Excellent video, Dave. Thank you for the information.
Great information as always!
Very thorough information.
Thank you!
Absolutely great explanation of water and the different options!
Thank you Dave. Great info. Helped me change my idea of filtration in my pack.
Another great video from the undisputed heavy-weight champion of bushcraft.
I'm surprised the new Lifestraw didn't get a mention though, it's basically a Squeeze but with the additional functionality of the old Lifestraw.
Can't wait for the lid!
Informative and beneficial video!
Excellent content. Always a valuable lessons.
Another good and informative video. That new filter cap is cool. Thank you for sharing your knowledge and time.
Thank you for this class.
Thank you brother! This has come about at the perfect time as I am re-evaluating my water purification system and updating my kit
Thank you from those of us that are not Hydro-Chemist! Great info and right to the point.
Thanks for the great information
GREAT VIDEO
Awesome idea for the lid… maybe an extra side deal with a hole in it so you can hang the bottle too. Very nice!
Great fckn video. In depth, no BS. Thanks Dave.
excellent video
Well done!
I’m thankful for this video and learned a lot. I do a lot of fishing, camping day hikes and carry a sawyer as my only back up water source. I’ve never been a situation to use it but now I know truly how ineffective it could be.
This is good stuff
Thank you sir.
Very informative and I would say Thank You ! The video is a little wordy which makes it seem longer than it needs to be. I will say it is very informative and I appreciate the time taken to share with us !
Nice video. I like to call a good water plan the equivalent to having a CC with a high limit on as roast trop ... you can just keep going as long as you don't run out. I like how you referred to the CDC and demonstrated each item. Very thorough. The water boil & shelter test at basic is probably the most important thing I've ever learned for outdoor survival. Great job!
Is there a "shelf life" to these filters that can disinfect water? The number of gallons was discussed, but do I also need to consider deterioration of the filter over time. Can I put them in the trunk of my vehicle and forget about them?
Excellent in-depth video. Thank you Dave for taking the time to show us good options, and not least, giving us the details connected to disinfection and purification of water. I would love if you also added some kind of clinically testing of the water after the different options, that way there would be no doubt connected to the quality / efficiency of the different options. Thanks again for an super and educational video
Well done.
Great and informative video
Great video as always. Thank you for properly sharing this information. I've been in the water industry for over 30 years and I see people constantly mislead people on survival water treatment. You did a Great job.
My go-to is the Katadyn Pocket filter. Plus I always have chlorine dioxide not only for water treatment but also medical. I've seen it cure malaria quicker than any pharmaceutical. I will pack a small carbon for any taste issues but, I never run any untreated water through a carbon because the micro-organisms will colonize in the carbon and actually make the water worse with time. In regards to UV, I'm not a fan of it because I have seen too many instances where people have damaged their eye retinas, any turbidity renders it ineffective, and there's no way to verify its effectiveness. I only use UV for lab-grade water.
The CNOC bags suck because the slider is too tough to get on. Nice video! I like the steripen! 😁👍👍🇺🇸
Grayl! Filters are pricey as well. But it's a no brainer deal. It works. Milbank bag as well.
Dave, ty
Great video. I would like to add some details. Activate carbon works by having active sites, not by a strict pore size. The pore size of activated carbon. Activated carbon works mainly by abortions, not filtration. Graly purifiers utilize a combination of activated carbon, electroadsorption, and ion exchange technology to purify water.
i used to use a sawyer with a platypus carbon filter inline, Since grayl came out.. its my go to ..
I've been using the Grayl Geopress since 2020 on day trips and backpacking trips. For me it is now my preferred method of treating water.
Dave dropping some knowledge! Hope you're still running the school when my boys are old enough to do it
Nice looking bag on the picnic table 😊
Great, Great, Great video! Thanks Dave and BOOMER SOONER!!!
Katadyn Hiker micro filter. Going for 35 years. .02 absolute pore size. Fiber filbert carbon filter. Prescreen filter. Need more pre filter wrap a coffee filter around the acorn. Need viral, buy the Hiker Pro or just buy the replacement filter cartridge. A bit of hassle with the tubes but have lead many 4 day backpacking trips them. Used to under the Pur brand until sold to Katadyn.
Good video. Each person is different. I personally love my Grayle along with my mill bag. I also will use a stainless steel bottle with the mill bag then boil my water. I do have a Sawyer and like the fact that it fits on a smart water bottle, plus the Sawyer isn't expensive and a smart water bottle isn't that expensive either.
Appreciate how you give the pros and limitations of various devices and methods. I am interested in your thoughts on the P&G water purification system. It claims to address all the issues you discussed including some chemicals and heavy metals.

There is a LOT of good information in this video, thank you! I do have one question I have not found an answer for: I live in the Appalachian region of NW PA, and there are several natural seeps on my land, at the base of the the mountain, but just above the ground water creek. Is that water safe, when it comes out of the rock, or does it also need processing to drink?
very informative video. is there any plan in the future to have those bottle caps for the sawyer filters that will fit Kleen Kanteen large mouth bottles? I do prefer boiling, after pre-filtering, but when I can't I do carry a Sawyer mini.
Usually not a good idea to stare at a UVC light source.
Dave, Thank you, What about PFAS? Is there a packable solution to removing PFAS contaminants from our drinking water?
Filter slow, watch for frozen hoses and filter parts, might want to sleep with it, always think about digesting your map for finding water ie topography not just reading the trail map and relying on marked water sources. Make sure you can always boil.
Does that "lid" also fit the Sawyer Mini?
Water most important prep by far.
Know everything about it
I personally have a sawyer filter and Boil in a container as my plan. I will probably add millbank bag to pre filter and as a backup to my sawyer
What is your opinion on the survival and hunting use of blowguns?
Sawyer cleaning coupling makes backwash a piece of cake
How about putting a coffee filter on the mouth of the cup as a pre filter.
Dave have you seen the Survivor filter straw? It seems like a much better choice now over the Frontier pro. Thoughts?
Hi Dave just quick question I have the Sawyer mini in my kit so are you saying it takes out all those elements except viruses if so can I like use the Sawyer into a cup/pot then boil for viruses is that a good way to do it? Hope you reply. Thank you.
It's my understanding that viruses are a very low concern in North America as long as you're not collecting your water straight from a sewage source or immediately downstream from freshly dead bodies. Most viruses don't live long outside of a body making your chances very slim of it being a problem from most woodland water sources in Ohio. Chemicals and metals are a different concern, and one that that should concern most Ohioans, especially those who live along the Ohio river valley for what should be obvious reasons.
What is your opinion of the brown bags y'all used to sell? As good as the Pathfinder one?
Dave. EXCELLENT VIDEO! THANKS
Dave,
what is your opinion on larger water filters like the Big Berkey for emergency situations where you would stay at home? Are they worth it, do they work, and what level of protection do they provide? Additionally, are there other companies that make something similar you would recommend? Thanks for the video.
I use my grail every day. If you prefilter the water with a mil bag or even a t-shirt. The filter lasts quite a long time
Hey Dave, not sure if you’re aware of Purinize Drops but they are supposed to be the only option that removes biological and chemical contaminants by coagulating them. I think they’re a US based company. I carry them as a final option.
Platypus and Katyden make designated separate carbon filters. I do not know the effectiveness of these when paired with a hollow fiber filter like the sawyer or similar.
It might be food for thought.
How do you sufficiently disinfect the exterior of those that must go into the source? And your hands?
👍
