I've been searching for it for a while and couldn't find anything.';

'>>2724027
I work in an industry tangentially related to materials science. The rating on these filters is determined by a recognized guideline, either ASTM D6908 or ISO 20468. I know as a matter of fact that Sawyer contracts their testing through BCS, North Florida (whom I work closely with).

Their claim of filter efficacy and life is based on that testing. Lifestraw tests their filters by one of those standards as well, and probably contracts it to a company like BCS (ostensibly; as a large company they’d catch hell for not testing to a recognized standard practice). That’s where the claims come from. You can probably find the test results in their websites.

>just use a Lifestraw
Lifestraw is a brand, but we have to assume you’re talking about their most popular product. It has a worse flow rate, much shorter lifespan (1,000 gallons), and a filter that’s only half as effective as a Sawyer Squeeze (.2 microns vs .1 microns). Why recommend it?';

Yeah, and if you've spend 3 more seconds actually reading it, you'd see there's nothing about bacteria, viruses or when exactly were those tests concluded: did they test it on a brand new filters? After filtering 1000 gallons? After 100,000 gallons (like advertised)? We don't know.
There was plenty about speed of water flow, ph, hardness and what not, I'll give you that, but it's not transparent at all how used those filters were before being tested.

>Faster flowing with the lighter, softer pouch

>Is this a good water filter?
I'd assume just about any filter from Katadyn, Sawyer, MSR or other reputable brand should be fine. I find it hard to believe that it'll actually filter up to 100 000 gallons but with regural maintenance (backflushing in field and more thorough cleaning at home) people have gotten several years out of their filters.
Also if you want to extend the lifetime of your primary filter, then use a sediment filter (or run it trough a bandana, coffee filter or something) to prefilter the water before running it trough your main filter.

When I got home I looked up the manufacturers instructions for maintenance. Sure enough there’s an article on how to clean, sanitize, and store a filter. I was just going by shit I’d read on forums, but it was the same as the website.

Nowhere does anyone say shit about using distilled water. I searched and found a few people who had the same issue. The best guess is that municipal water supplies are so hard that calcium deposits start growing and aren’t flushed out with use, so they clog the filter.';

Non-standard practice, though not unheard of.

The Lifestraw is less effective and has a worse flow rate. Not to mention its size makes it incompatible with SmartWater bottles. You still haven’t stated why you recommend it.';

this was my issue. i used a 50/50 mix of hot (not boiling) distilled water and vinegar. worked like brand new again. when i get back from trips, i back flush with distilled. night before i leave, i soak 50/50 vinegar distilled. no more problems since.';

'>>2724070
They run these tests on brand new filters, because it would be nearby impossible to control the tests with used up filters. The minerals in water are way different in different places. How much sediment is getting in to the filter etc. The same filter that works well after 1000 litres in one place may get gunked up from just 100 litres at another place.
>>2724074
The way these Sawyer filters work is that they have very miniscule pores in the fibres that let the water trough. Even if the filter gets dirty from all the gunk, it should still never be able to let the nasties trough because the pores are not getting any larger from use. They just get stuff stuck in them. Meanwhile the activated carbon purifiers themselves keep on letting water trough even when they loose their effectiveness.';

'>>2724082
>Non-standard practice
Company that goes beyond standards to provide a healthy product is better than one that does not.
And a company that makes claims about being great even after 100,000 gallons, without proving they've actually tested it, isn't as trustworthy as company promising you only 1000 gallons, but actually showing tests they did.

Also having a carbon filter is nice (as I've already mentioned in the first post). I think having one is more important than having a high flow rate.

>>2724087
>They run these tests on brand new filters, because it would be nearby impossible to control the tests with used up filters.
Somehow Lifestraw and Sagan managed to do just that. Seems like either skill issue or an attempt to hide how good or bad Sayer filters actually are.

They could get damaged through use and get bigger, if materials they used were subpar.';

I mean if it gets rid of Protozoa and ecoli id say it works great! Chemicals and other stuff won’t kill your (quickly at least) however giardia could in a couple of days depending how dehydrated you are.

Lifestraws are great when you have water nearby, but how the fuck you going to transfer it to a container? They work great if you’re sleeping next to a cleanish body of water but if you’ve ever used a life straw you’ll know that you will be spending a fair amount of time sucking.
