[@K9River]

I used one on a 4 day float on the Missouri, which specifically states to bring your own water because the river water isn't potable. So many cows poop in it, not to mention the herbicides, fertilizers, etc. from farming and ranching. I used the Grayl and it worked pretty well. The filtered water was clear and tasted good. I bought a replacement filter after putting only 4 gallons through the first one. The filter slowed down toward the end because the river water truly was nasty and dirty.

[@waterfilterguru]

Thanks for sharing! One thought is that it might have clogged quickly due to the presence of suspended solids and/ or sediment. If the eater is brown, it indicates lots of this. A quick fix to extend the life of filters would be to first filter through a shirt or other cloth to remove the larger particles that clog the Grayl filter 🙂

You can extend your Grayl filter by pre filtering your water before using the Grayl. It is slower process but will extend your filter. Great option if your in a survival or bushcrafter.

[@waterfilterguru]

Most important thing is you don't have to suck the water out. You can just drink it which means you can pour it into another container and generate a storage of cleaned water. Which you cannot do with these other type of filters very well at all. So it's a great thing and get the larger size 24 oz 1. They make a bigger size as well and I don't think it's that heavy. It's maybe a little bit but with all the features it has. I think it's fantastic for travel. Don't have to have any extra bottles with you..boom you got water

Can you do a video on water filtration for a bug out bag when you largely have access to brackish or questionable water like SW Florida after a hurricane? It is highly likely to contain bacteria, blue-green algae, and pesticide runoffs. I see a lot of products that are designed for access to mountain streams, but we have to consider every body of water could have gators or snakes in it. Let alone possibly salt water. Also, this may be our only water source for a few days until bottled water can be brought in, if our home is destroyed.

Theoretically it can be used with any untreated water (stagnant or not). Make sure the water is clear before filtering, as suspended particles that make water murky will clog the filter extremely fast. Additional disinfection (like boiling) is always prudent.

It all depends on the source water being filtered. Not every type of filter is suitable for every application, and there is no one size fits all solution. You can know a system does what it claims if the brand provides third-party lab testing data, or even better if the product holds and official certification from the NSF, WQA, IAPMO or similar certification body. We've done some lab testing of our own on products, but this is 'real world' testing and is neither comprehensive, nor conclusive, but still cool to see how products perform in the wild.

[@IonorRea]

There is a larger version of this bottle with nearly double of the total water purifying capacity before needing a new filter which is far better value for money if you plan to use water cleaning heavily during travel, whatever hike or international, the difference in filter prices between filters for UltraPress and larger GeoPress are negligible despite the huge gap in the amount of (claimed) total purified water. As for claims of other producers which often did not provide the same level of water purification (filter with smaller holes or more filtering layers likely gets clogged faster if other parameters are the same), these claims are likely just false advertising, as many companies whose systems have often much smaller filters tends to claim a much higher total amount of filtered/purified water before the need for filter replacement, likely hoping that nobody will ever put their products into any kind of longevity test, as you really should replace these filters after the end of hiking season each year anyway, especially if they cannot be backflushed because stuff trapped inside start decomposing and further clogging filter with the growth of various nasty stuff. Thus also the claims from Grayl about using the same filter for 3 years are rather questionable even with some kind of boiled water treatment to somewhat disinfect already used filters. Use of leftover water filters from the previous year that may or may not work as intended should be similarly to used condoms reserved for people you are trying to get rid of without making local police too much suspicious about you... Anyway, it would be nice if you test some of these highly portable systems with overly optimistic filter lifespans if they can approach anywhere near their claimed amount of total cleaned water. My intuition tells me... NO WAY. Perhaps you will strike a nice viral video and a bunch of new subscribers from hiking, prepping, and military-oriented community which tend to care if their equipment will keep them alive even if things did not go according to plan...

Especially for microbes that can exist on surfaces for hours or days. I'm imagining a survival scenario where you may not have access to hand sanitizer etc.

This is a valid concern. The drinking spout does have a waterproof cap that creates a seal.

Depends on the application! Where would you be using the portable filter? Extended backpacking trip? Car camping? Emergency preparedness? Daily on the go filtration with municipally treated water? There are a few options in the description, actually.

[@juvehe]

@@waterfilterguru At the moment it'll just be used for "long" hikes, or could be considered extended backpacking trips. I'll be drinking water from lakes up in the mountains.

[@waterfilterguru]

@@juvehe Honestly for day hiking, the Grayl bottle is awesome. I use it for day hikes. Extended backpacking you might want to consider something lighter weight, like the Sawyer micro squeeze bit.ly/3rPaf0E (rei.com)

[@juvehe]

@@waterfilterguru awesome! Thank you so much!

[@StevenAllen-z6b]

Is there a specific reason not to use the grail with treated city water? I live in Detroit and we are persistently lied to about the quality of our tap water. Boil warnings are frequent and city government is not trustworthy. I need an every day filter option that I can take with me and use with city water.

[@waterfilterguru]

There are better more capable options if you are primarily drinking treated city water while not under a boil water advisory. Basically you don't need a filter which reduces bacteria if you are filtering water that's already been disinfected as that would be redundant. It might be more prudent to invest in a system that's more capable of dealing with contaminants found in treated city water with a higher capacity

[@theinterstellarcollection]

Curious on your thoughts on using this as a dedicated tap water bottle? Here’s the thing though - I mean primarily using it in the US. I know it’s overkill, but besides that, do people just use this let’s say at their office job, in their own homes or when they travel within the US to hotels? I don’t really trust our water is as clean as it’s being told to us, so I’m wondering if this would solve that. Also, I responded earlier today to another comment regarding whether it’s concern to be centralizing bacteria/potentially viruses in a filter attached to the bottom of this water bottle that I plan on drinking from daily. Thoughts on that? I know about replacing the filter according to the directions, but I’m wondering your thoughts on the fact that we are storing this harmful stuff right there on the bottle itself. I wouldn’t want to cause more harm than good. I did see your recommendations at the end, but I’m not afraid to spend more money if it means it’s the best of the best. Since this does viruses, too (even if not necessary), that’s what brought me to it. Thanks!

[@waterfilterguru]

This would be overkill for tap water. Tap water is treated so, in most cases, there is not risk of microbiological contaminants. If you will be filtering tap water, I'd recommend something else like the Clearly Filtered bottle filter geni.us/eo1oEIs which is capable of reducing common contaminants found in treated tap water

[@theinterstellarcollection]

@@waterfilterguru thanks so much for the response. This still makes me wonder though, what’s now in the water from the treatment? This is, I’m sure, a very uneducated question I am asking, but it still makes me wonder. If there are possibilities of viruses in our tap water, then this wouldn’t be overkill. But how can we be certain? Is it really overkill if it’s not that expensive to manage (replacing as needed)? I’m also still wondering about how we centralize the bad stuff in a filter, yet we still drink from it. I know that’s crazy to say because it’s literally a filter, but it still once again makes me wonder. All i ever hear about anymore, at least in my area, is how the water is nasty. Or the water is a dirty color because of lead, etc… thanks so much for your time. I know my questions are pretty dumb but I feel you’d know best.

[@waterfilterguru]

@@theinterstellarcollection The disinfection process at the treatment plant, typically using chlorine or chloramine chemicals, destroys/ inactivates microbiological contaminants including bacteria, viruses, and parasites. This is why you can drink the tap water in the US without getting sick immediately, like in other countries around the world. That said, there are a whole host of other inorganic and organic impurities that can be present in tap water, which pose risk with long-term consumption. Learn all about that here waterfilterguru.com/common-drinking-water-contaminants/ As for your question about pathogens building up inside the filter - yes, this would happen. However no, they should not escape out of the filter into the filtered water, as long as you are replacing the filter according to the manufacturer's instructions.

[@kinomorrison8004]

So I could still get dissentary?

[@waterfilterguru]

Not if it's used according to the manufacturer's instructions

[@NothingToNoOneInParticular]

I LOVE my grayl, but for much need huge quantities I use a survivor pro x electric but I am not a gram weenie...kek

[@waterfilterguru]

Yep bottle filters sure aren't the best providing large quantities of water, you're absolutely right

[@patrickschlauch6638]

You forgot one important information, this one also filters viruses (0,02ym). I'm not sure if the others you recommend do as well, at least I could not find any hint. The Sawyer does defenitely not.

[@waterfilterguru]

Great callout. The MSR Guardian we recently tested kzbin.info/www/bejne/equcpqypj55mjrc also has a 0.02 micron pore size, but it does not have the additional filtration media capable of reducing chemical contaminants like the Grayl does

[@GTFBITK]

How does this work with urine?

[@waterfilterguru]

No idea - haven't tried. Let me know how it goes haha

[@GTFBITK]

In my area my katadyn befree is my day hike filter. My multiday is a grayl. I have a bigger pack because of the bulk.

[@waterfilterguru]

Thanks for sharing!

[@sweetbeep]

Does the katadyn filter everything that a Grayl does?

[@GTFBITK]

@sweetbeep the grayl is better and I think it has charcoal in the filter to filter out some chemicals. If I was going to unknown areas I'd get the grayl. I hike mostly in Maine so the Katadyn is good to go. A small issue with the katadyn filter is if there is water in it and it's freezes, it will break. I'm not sure about the grayl. Good luck on your journeys.

[@sweetbeep]

@@GTFBITK thanks. Does the Grayl filter pharma drugs from water?

[@GTFBITK]

@@sweetbeep it probably filters out some, but probably not most. Their website doesnt name pharmaceuticals specifically.

[@Gadgeteer22]

Nice review. I also enjoyed your more detailed review on your web site.

[@waterfilterguru]

Thanks for watching! I'm glad your found the video and written reviews helpful!

[@Gusssugs]

So is this a water filter or a water purifier? You say filter a lot! Thanks

[@waterfilterguru]

I know they call it a purifier because it reduces bacteria and viruses

[@MRRAWRAW1]

Do more portable devices please

[@waterfilterguru]

Thanks for the request! Well noted, and we will be sure to do so!

[@waldo-ot6ul]

They now have 24 oz bottles

[@waterfilterguru]

Good call out!

[@sunnindawg]

Got one for $75. It's bulky and a little heavy. Provides about a cup of water. I bought this to travel to Medida Yucatan. I like the Portawell for a disaster.

[@waterfilterguru]

Perfect use case for each! I used my Ultrapress in Costa Rica recently

[@aeptacon]

But they aren't nsf certified. I just bought a few but I'm concerned hope it is not another berkey

[@waterfilterguru]

While not certified, they are independently tested by a certified laboratory to meet or exceed NSF/ANSI protocol 42 and 53 for pathogen and chemical removal; meets the the United States Environmental Protection Agency's Guide Standard and Protocol for testing microbiological water purifiers

[@mixeddrinks8100]

this feels more like a in case of emergency use

[@waterfilterguru]

Yeah these are a solid choice for emergency prep. Keep one in your car, etc.

[@timjrvine]

I carry one in my backpack when I go ride my motorbike offroad because I've been caught out before and had to drink river water. We were fine but now I carry it with me on rides.

[@sweetbeep]

As opposed to what?

Protip: When do you know it's time to change the filter? By blowing air in to it. I found this earlier when I was attempting to make it dry faster. When you have a new filter, you hardly can get any air through. I was using Geopress daily for several months in a base camp. Tip not based on actual science. 👨‍🔬

[@waterfilterguru]

Right on, thanks for sharing!

[@davemcbeardface8976]

I’ll stick with my Katadyn Vairo

[@waterfilterguru]

Fair enough! The Katadyn Vario is a solid filter

[@waldo-ot6ul]

They are two different uses though one is more quick use and carry one is more for larger amounts of water

[@baileymoto]

The Vario is a filter, this is a purifier. Yours doesn’t protect against viruses, etc. Apples and oranges comparison.

[@WorldSurvivalist]

Just get stronger, it's not that heavy

[@waterfilterguru]

Backpackers count every ounce

[@LWBrown-md4wm]

Do you know of a water filter system that removes that 0.001 % of whatever all these filter systems can't seem to remove? If they could hook up with all these other systems, or just 1 other system, you'd be swinging for the fence with every swallow!!

[@waterfilterguru]

Reverse osmosis or distillation are the best methods to purify water. Not portable though

[@timothytso283]

12oz is heavy?? How weak is someone

[@waterfilterguru]

In regards to backpacking specifically, every oz counts

[@barker316]

loosen the cap first

[@waterfilterguru]

Yes! gotta loosen the cap to allow the pressure to release as you are pressing

[@nathancory7325]

Clogs up within 50 plunges if you're not prefiltering. Even if the water seems spotless. Failed us terribly on the Bibbulmun track. Kinda false advertising really the way grayl make it out you can just scoop up water from anywhere. Yeah sure. A handful of times before the product is buggered. May as well upsell a seperate dedicated filter bottle with it. If they'd mentioned I needed to filter the water before filtering the water.... I may have filtered grayl out of the equation. Cool concept, just completely full of shit.

[@waterfilterguru]

Thanks for sharing. Out of curiosity, what type of water sources were you filtering?

[@nathancory7325]

​@@waterfilterguru Clean West Australia rain water. Some of the cleanest water in the world. It was actually meant for Nepal this year but I'm just going with good old fashioned tablets.

[@marvinbrock2572]

For me these are useless. Actually if you live in the uk it is pretty much useless. You cant use them with bleaches/chemicals so tap water and river water no good. You cant use them with salt water so thats also a no for saline rivers (salt mix). Also, you cant use them in peaty water which rules out any hill rivers and lochs/lakes in much of the Uk and basically all of Scotland. In fact, if it isn’t glacial water you probably can’t use the press on it. I was just travelling the john muir way and stopped by a stream to top up my 4 small water bottles and the first was nearly clear and by the fourth it was dirt brown. If you see that, your filter has been destroyed by the tannins. Much better off with a paper type filter and replacing it when needed as these don’t become ’broken’ by the water. Ive told their marketing to tell the truth but they just rephrase everything i say back to me as if im a one off case. Its the water, not me. Their statement is this, ‘GRAYL… make clean drinking water anywhere on earth!’. Well, that’s just bull. Overpriced and broken by Scottish hill water in its first use. Feeling VERY ripped off. P.s. Grayl consider their ‘instruction manual’ (that you presumably read after purchase) to be their disclaimer so 2 things- read it, then send your Grayl back to the reseller. Bear in mind, they don’t refer to peaty water etc, they refer to tannins, so watch carefully because if you get poisoned, they will just place blame on you for not properly reading their instructions. No good if you are stuck miles from a healthy water source. Fortunately, peaty water is actually healthy for you. You just gotta be careful that an animal didn’t die in the water upstream.
