LifeStraw Filtered Dirty Water Under the Microscope 

100%

No shit?

@@apapz3245 nah i take plenty of shits

Perfectly honest would be showing what colonies grew from the filtered water. He did that, but should have featured it more prominently. EDIT: Thanks to the 10 people who corrected this very important comment

He did though

That's a good question, because if I was going to buy one (and I'm thinking about it now, for sure!) I would have definitely sought out a video just like this to make sure the claims are true! This video is great accidental advertising.

Let's say lifestraw made an ad like this, would you in all honesty believe the results or would you assume that the test had been tampered with?Having independent people do these sorts of tests is the best advertising they can do (and they get it for free no less)

This video is an ad

@@MvMArcher Companies confident in their products are happy to hand over their products to independent RU-vidrs for rigorous tests without demanding any kind of positive outcome. "Take it, test it, make up your mind, and let your viewers know" -- LifeStraw could have just done that. If it's a good, novel product, at least one video will go viral.

They did, and vou just watched it.

I think of my life straw like I do insurance or a firearm. Have it, hope to never need to use it, and take reasonable steps to reduce my chance of needing to use it.

@@Snadzies exactly

they filter 1000 litres. Seems a bit much for 'emergency only'

Did you survive

@@mrsnail6091 Unfortunately I don’t believe they did.

@@mrsnail6091 I don't think they survived bro

Buy 5 more. 2 is one. One is none

Agh bad decision! Should have gone with a Lifestraw Go, much easier to use than the lifestraw and is much more of an essential item.

Sad that I returned my 4pk.

i would buy one if i actually had use for it, I drink out of a bottle all the time. lol

@@lokey416 it’s intended more as a camping/survival item. Less so everyday use

there’s only a few countries in Africa that has water insecurity not the whole continent the Africa adverts on tv did you dirty lol

@@thelittlestgiant i mean to be fair talking about Africa in a vague non specific way when we are talking about a continent is a problem in and of itself You wouldn't say oh spots in america are experiencing droughts to mean a spot in mexico and another in uper canada would you?

@@DimT670 I understand that Africa is gigantic and has many countries within it with many different cultures, practices, and biomes. I knew what I said was true about the LifeStraw though, and didn’t feel like doing extensive research for specifics before leaving a positive comment on a RU-vid video….. Take your overly sensitive negativity and shove it up your ass. Get a life.

Honestly, I didn't know what to expect but it was fun to learn what it is capable of.

Oh yeah yeah

OH YEAH YEAH

@@sci-inspi at least it works as they've claimed

@@sci-inspi Can you also test one of the cheap alternative filters from amazon that are no name brands ? Like Finerfilters or Lixada or Sawyer or Hydramate.

Plot twist this is the ad

If they do, they better pay me.

I wouldn't have believed them. My dude here is a 3rd party with no reason to lie to us, so his experiment is much more valuable and believable.

they are excellent to pack away in an emergency kit.

Lol same. 🤣

Do you have to clean the life straw ?

man people are so weak you can't even drink tap water without getting diarrhea i have been drinking the same water straight out of the ground unfiltered my whole life and not once has water ever given me any sort of sickness. i rarely get sick maybe once every 5 years and most the time it's because of other people.

Thanks Mike.

Thanks Mark.

works better than I thought it would, and I have one already.

Well It uses standard 0.2 micron filter fibre. I assume made by the couple companies that make such fiber. as long as the filter cloth is reliably made.... There isn't much to go wrong. Many much more expensive filter units use same filtering size. Mostly lifestraw is cheap, because it is bare bones. Their whole unit cost kinda what some filter replacement ments costs on other units. Which pretty much tells the story. Lifestraw costs what their filter element costs. It is filter element in a tube and the tube costs nearly nothing. It isn't magic. Just bare bones. Also since their unit doesn't cost that much less than what replacement fibre filter units costs on other devices..... Filter materials come from similar grade sources. On other units one is paying for the pumping units, extra secondary filters, active carbon catridges and so on. And should one go much higher in price, then one can start to see just even smaller filter size. Go all the way and one has reverse osmosis kit, since filter is tight enough to filter out salt molecyles.

I think the conclusion is that you can still get sick or die since it doesn't filters viruses and those other things mentioned. Am I right? If I am wrong then why is it that you think I am wrong? Thanks.

@@taowaycamino4891 That isn't entirely incorrect, but viruses, heavy metals, and pesticides (the three items mentioned) are far rarer than bacteria and protozoa. In a remote location that isn't near farm land or an industrial complex you don't need to worry about lethal amounts of heavy metals (things like uranium, lead, gold, and iron) and pesticides (chemicals used on crops typically to kill bugs), as those problems are almost entirely man made. Viruses are a bit more complex, but they cannot survive long without a host. The normal way they spread is by being excreted through a living being already infected with it (relevantly right now through sneezes), so the only real danger is if there's an animal corpse upstream and even then the viruses can't necessarily infect humans, as they generally specialize to best infect certain types of animals. Bacteria and protozoa are generally likely to cause illness, but live everywhere in massive quantities, so the chance of at least a _couple_ of them being dangerous is extremely high. Bottom line is that the product decreases your chances of getting sick from a near guarantee to an anomaly.

@@taowaycamino4891 I’d say that it’s still something good to have should you find yourself stranded and without a clean source of water or if you run out of water in your bottle while hiking. Even if it doesn’t work fully it’s better than drinking straight from the stream.

Same. I was surprised by how few colonies grew, because we used those filters usually after centrifugation to further purify the supernatant. The filter alone is quite excellent in this straw.

I'm almost certain that the bacterial growth came from other contaminant vector, like the dropper or the petri dish itself.

@@victoriazero8869 it looks like a yeast colony to me, so you could be right. I don't think it's dangerous anyways. you can drink the yeast and it will go in your stomach and die instantly so your body can handle it.

I've always felt fairly safe transferring brackish water from a LifeStraw Go bottle to a Camelbak All Clear UV treatment bottle when boiling in the field is completely impractical

And it's led to these being distributed in parts of the world where drinking water is routinely unsafe. It's a game-changer.

Those filters on the fridge barely do anything, my tap water has a total dissolved solids(TDS) of 330 ppm, while filtered fridge water has a TDS of 230 ppm. Spring water from a natural spring has TDS of 40 ppm. Best not to drink tap or filtered fridge water.

@@perrinmosca5942 your body needs some DS.

@@snowcow1173 probably not if you're drinking bits of lead. It really depends on the contaminants.

@@snowcow1173 your exactly right. Ppl who aren't strengthening their immune system will regret it one day.

@@snowcow1173 Good luck strengthening your immune system to lead, arsenic, and microplastics. There is much worse than bacteria in tap water, unfortunately.

Life straw actually has a lot of different types of filters now... I have one in my fridge for water.

@@backwoodsbaby9729 , I'm arguing from the same perspective as the video, that is for the outdoors like camping, hiking, biking and specifically SHTF. I might go as far as to say that the filter in your fridge cannot perform this task. And even if it could, it would be severely limited by the volume of water filtered before it breaks. Your filter is for 1st world problems, where the water is so clean that the chemicals that make it clean are purportedly killing you. It's a final stage filter. I have a 2L water jug with a filter on my kitchen counter for that as well, but I would never use it to filter water like in this video.

@@jdshl8423 check out the line of products they have before assuming things. I wouldn't put sediment filled water in it but I could put lake water in it.

Pre-filtering extends the lifespan of that very fine filter. Get the big stuff out so the LifeStraw only has to tackle the little guys.

Bro was like time to grow some microbes

There's better quality filters out there than lifestraw. Sawyer makes their squeeze which has been a favorite among hikers and backpackers for years. Platypus is also known for a good gravity bled system If you want virus elimination there's some purifier, UV, and tablet options available too.

Lifestraw also has a carbon filter iirc

@@twizz420 That doesn't stop viruses. You need a 0.02 micro or smaller filter for that. Lifestraw is a 0.2 micron filter. The Sawyer Squeeze is 0.1 micron. Suvivor sells a $30 straw type filter that's 0.05 microns which will get a lot of viruses but falls short of the EPA regulation. They have a pump style filter that's down to 0.01 micron that you can get for $60. There's 0 reason to get a life straw. A lifestraw's made for backcountry water in north america where you can expect the water to be fairly clean. Chile's no going to be as save water wise.

@@Furluge As a hiker I completely agree and those are my 2 filtration systems I use hiking. Platypus for multiple people or when weight is less of a factor. Extremely easy to use and can filter a lot of water quickly. This is my go-to for 90% of trips. Sawyer squeeze for ultralight / single person use. It weighs under 100g though it is more effort to use. Also be careful not to lose the o-ring when filling. Most common filter for people on the PCT.

@@graham1034 I've got a platypus and I had been looking to get a sawyer squeeze but it looks like the innovation has marched along and I think I'm going to swtich over to a suvivor pro system. That one'll take out viruses and heavy metals so you can use it more areas. They've got a stray type filter that goes down to 0.05 microns too that's very cheap.

I'm so glad they are both OK! It's a good thing they were prepared, you just never know what can go wrong until it does.

I Wonder where those crusty patches come from?

With the disclaimer that tap water varies from area to area though! Where I live tap water gets strictly controlled, it is supposed to be even cleaner than bottled water from the store.

Now that would be concerning to know u have crap water compared to the straw

Most municipal water supplies are laden with chemicals to keep it “safe”. I have a gravity filter that takes 24 hours to filter one gallon through and I filter all my municipally supplied water for consumption in to get all the chemicals out. The filtered water tastes much better - sometimes the municipal water has a bad chlorine taste, probably bad growth of bacteria in the water.

@@u4riahsc laden with chemicals lol? Chlorine only, laden with nothing and safer than bottle one

@@u4riahsc Unless you live in a third world country, there's nothing in your tap water other than residual chlorine (unless you have contamination between the curb and your taps, which is your responsibility as the property owner). Municipal water is disinfected by chlorine or ozone at the plant, then buffered with chlorine while in transit to your home to maintain disinfection. If there are other chemicals, your piping requires replacement.

the product isnt made for the western market, they dont care for what people think of it. it has had plenty of third part labs and goverments testing. as its used for humanitarian aid, its main design. the goal was, and is to provide clean, safe drinking water to everyone

Well it was made to be used in places like Africa. If they had tried a scam Charities would have called them out pretty fast. Life straws are often given out by charities.

@@brokeandtired you would like to think so. Look at how many people believe in crystal healing and that essential oils will cure cancer.

@@brokeandtired the charities are scams

Part of you said it was a scam, so you made a judgment based on nothing. A few minutes of research would have taught you that these lifestraws are used the world over by soldiers, explorers, hunters, missionaries, etc. People are so lazy and quick to judge with zero intelligence invested.

I found out about this several years ago. I think it was just one guy who came up with this simple and cheap system to help get people clean water. I'm happy to see it gain attention.

So it doesn't work is basically what you're saying right?

Theyre saying it works, the harmful bacteria cant make it through the 0.2 micro filters.

@@rickyjiggens2180 They said it does work and that it makes sense as to why?

Of course, it's designed to filter anything

I would have thought rain would be largely free of microbes, if it hadn't touched ground yet.

How much use is testing ph? it would, at best, tell you if its going to burn you or not. Bacteria do have optimum PH ranges, but im not sure how much of a check the ph of water is

Wouldn't boiling the water and collecting the vapor in a kind of destillation process the best option? I am really bad at chemistry, so there are probably still pesticides and heavy metals that are water soluable which would be in the vapor, right?

@@Medhusalem distillation like that is fairly reliable. Cant say its perfect, cause i dont know, but its pretty darn good. The issue is distillation is energy and infrastructure intensive

@@ciarangale4738 what do you mean? You won't encounter water that is outside of a pH that is drinkable. Maybe if you're in a super volcanic area that's known to have very alkaline water, but you'd know that going in. No need to test pH.

@@littlejackalo5326 that was my point. I couldnt see how carrying PH strips could be valuable for finding potable water

I’m not sure you would lol!!

As somebody who's naturally curious as well and had a microscope growing up, I'd recommend against looking around your house with a microscope. You'll "bug" (haha pun kinda intended) yourself out. It's amazing what accumulates in living spaces. Unless you're an OCD riddled hypocondriac, your house is nasty under a microscope. Most things live in harmony with us, either helping/ignoring us or being generally harmless outside of the body, but it's still really freaky to see *exactly* how many microbes are chillin on your doorknobs, faucets, devices, and floors. Unless you harcore sanitize your kitchen top to bottom every day, you'd probably be pretty grossed out in there too, and maybe even still.

What would happen if you actually drank that dirty water👀

@@anna.318 hard to say, depends on what's in it. Likely diarrhea, stomach discomfort and possibly fever until your immune system deals with whatever microbes were actually in the water.

There are cheap handheld portable microscopes by microbrite if i recall correctly, great value, I've only got the 60-120x one with LED lighting, use it for hobbyist mineralogy and it has never let me down
