What you need for extracting liquids without contamination is a peristaltic pump. It's basically just a straight tube from end to end, nothing ever touches the liquid in the tube. The pump pinches the tube with rollers, which transfers liquid without physically touching it. They're used in medical applications and they can very accurately dispense a defined amount of liquid down to fractions of milliliters.

One thing in common I found with most of these filters, they all filter out bacteria to near perfection, but not viruses. For people used to drinking treated water from big cities, the virus the filters missed can make you sick, unless the water are further treated. But it is a lot better than no treatment. The best way to treat filtered water in a survival situation would be to leave it in a copper vase for 1/2 a day, or add more copper wires or silver into it for shorter wait time.

[@jens-kristiantofthansen9376]

Your final comments RE: debris has me curious, so - lifestraw, vacuum tubing, collection container with two ports in the lid, second port connected also via vacuum tubing to a vacuum pump. Before connecting the lifestraw, sanitize the rig and run some purified water through the rig to pull as much debris out as possible before your sample collection run. Then nearly immediately connect the lifestraw, run the vacuum pump for however long and drain the samples. No risk of contaminating the pump so long as the sample container is large enough, but also able to utilize lab-grade materials in the spots where it matters and properly clean them pre-sample.

[@michaelccozens]

Something I wondered about laundry sanitizers is less about whether they work directly than about whether they're necessary in the context in which they're used. Sure, they probably kill a lot of stuff in the wash itself, but is it anything that would survive the rest of the laundry cycle (eg drying, storage, etc.) in meaningful populations? By the time you go to use an item that's been washed with laundry sanitizer, is it effectively any less infectious than the same item washed without sanitizer? It definitely feels like the old marketing ploy of having a "solution" in search of a "problem", so to speak. If there were significant amounts of infection from laundry (outside very specific special circumstances, of course), I think we'd be hearing about it from public-health officials, not detergent hucksters.

(including sterile tissue culture plastics, there's less of it and it's sterile dust, but it's there) The biggest thing if you wanted to do this sort of negative control on your own would not even be using distilled water, but cleaning the glass slides and cover slips, they tend to be dust (and oil) magnets, and sometimes have residue on the surface from manufacturing.

[@michaelccozens]

@@clou09 There's a lot of parallels here with the modern, holistic approach to pest control in agriculture, called "Integrated Pest Management" or IPM. One proactive approach is to ensure that possible niches in a given ecosystem that could support a pest population are seeded with benign or even beneficial competitors to the pests. Such populations can be established and supported at surprisingly-low cost, and work without the many harmful effects on the ecosystems of healthy soil that often come with harsher chemical methods, which are reserved for more dire situations. Also a number of parallels to the analysis of historical geopolitics ("Art of War" kinda stuff). It's like how much of the north coast of France was ceded to the Vikings who then became the Normans; doing so incorporated the Normans into the existing power structure, and also created a buffer for the rest of France. Thereafter, any Vikings raiding the north coast were met with other Vikings who were intimately familiar with their tactics and not at all happy to see them. A invasion of pathogens looks a lot like a military invasion; for example, the invader needs to establish a viable beachhead before a wider assault can be launched.

What happens if you let the filtered water (in an alcohol wiped jar) sit? Will it go bad eventually? I'm curious how long it would take in an open container from just stuff in the air vs a closed, but not airtight container.

[@google-is-a-stupid-piece-o2543]

Why would it go bad if all of the bacteria and microorganisms have been removed? There's nothing left to spoil it.

[@RubelliteFae]

Because air isn't pure gas. I guess a better way of putting it would be "How much does air quality affect spoilage?"

[@allenwatkins4972]

Water doesn't "go bad."

[@RubelliteFae]

@@allenwatkins4972 Strange that we have the word potable, then

[@RedStripeMedia]

In an open container it will eventually as particles in the air fall in it? An actual air tight container hypothetically never.

My daughter used a lifestraw filter while hiking in the Tonto National Forest in Arizona for 50 days as part of a wilderness survival class. She drank out of fetted cow pond water, one cow pond had a dead cow in it that she drank out of using a lifestraw filter. They are the real deal.

[@PantsuMann]

Well thats reassuring. I have used my lifestraw only 2 times, and that was when my water bottle depleted and we hadn't got a fire going yet. We found a small lake with jetty so I went out on it laid flat on the jetty and drank through the straw to my hearts content and it was very refreshing! I mean I trusted the straw to not give me diearreah on the trail, but still, this test confirms that it actually does remove all the bacteria and bad stuff. Cool! Thanks for sharing!

People like you are genuine heroes. Thank you.

[@Makaya9s]

That siphon is such a great add-on to fill up a bottle while exploring the wilderness

[@Shift18]

I took a life straw bottle with me on a kayaking trip to save on space and waste and it works incredibly well! You could just dunk the bottle into the lake, screw on the cap with the life straw built into it and start drinking immediately because it filtered it as you drank. It was super weird at first but it was amazing to always have fresh cold water right next to you.

[@AndRei-yc3ti]

The only question is - how many times can u use the straw? How do u clean it?

[@Shift18]

@@AndRei-yc3ti it's been quite a few years since I used it so my info might not be accurate, but I think to clean it you can run water through it backwards like most filters. I think it only has a lifespan of a few years too. But I remember it not being crazy expensive and an amazing investment even if I didn't get much use out of it

[@Hawtload]

thank you for this I remember seeing that it's not meant for filtering chemicals, so anyone who has one please keep that in mind

[@radiantbladez]

Awesome. I have a life straw knew it had some quality filtration but didn't know it was this good!

[@MultiSciGeek]

Do the powder/gel that you dump into dirty water, shake the bottle, and all the mud and stuff sinks to the bottom and you get clear water.

[@zacharyrusch312]

I have a life straw (present from Grandfather) and it’s really neat and I’m glad to see it’s filter works like a charm

[@kap79]

That's amazing. Good to see it actually works as described.

[@demilung]

This turned out way better than I expected.

[@user-sy4tz6rm2y]

as a retired waterplant operator , I am impressed at it's ability to remove bacteria and solids from the water

[@g1stylempdesign929]

These Life Straws get the Bugs out in your big out kit. Great gift for people you love

[@SecularMentat]

Yeah, that was a very effective point of data for making a case for the life straw.

[@jonlee72]

Thanks for the test. It seems pretty definitive and I have a few Lifestraws for emergencies.

[@CarlosRodriguez-hb3vq]

I carry a Lifestraw as a backup on long hikes. It’s good to know it would actually work if I needed it

[@ThePapawhisky]

Hiking in the desert I often drink from cattle troughs and cow ponds. I use alum as a flocculant before filtering. my understanding is that the flocculant removes not only organic matter but also removes a majority of the organisms. Would love see that tested.

[@VIKING-SON]

Thanks for taking the time to verify how well Life straw works. I recently purchased one for my emergency go bag / bugout bag. To see someone do an independent testing like this was extremely helpful. Again thanks for your time and efforts. Sincerely CWO SHOOK U.S. Army Ret.

[@EnligUlv]

Wow I’m shocked. I’ve had this very same product in my last three vehicles from CA to CO and back to CA about a dozen years. Never have had to use it yet, but I’m glad it works.

[@stevehensonuk]

Awesome - I bought some of these on faith - so great to see how well they really work! Thanks
