Does "LifeStraw" Really Remove Parasites? A Look Under the Microscope.

Here we delve into the claims made by "LifeStraw" that 99.9% of bacteria and parasites are removed. With my trusty microscope I compare pond water with filtered water using "LifeStraw". This is not a paid advertisement.
Equipment Used:
AmScope SM-4TZ-144A Professional Trinocular Stereo Zoom Microscope, WH10x Eyepieces, Double-Arm Boom Stand
AmScope T490B Compound Trinocular Microscope, 40x-2000x Magnification, Halogen Light, Abbe Condenser, 2-Layer Mechanical Stage, High-Resolution Optics
OMAX 18.0 MP USB3.0 Digital Camera for Microscope

As a teen I was really into outdoor survival stuff. Had a few of these, never got sick. However there are chemicals out there that life straw cannot remove, so choosing the cleanest water you can find is important.

[@soulife8383]

PFAS are just extra calories! 😃

[@glenecollins]

As far as I know the modern ones don’t have any activated charcoal in them so they can’t remove anything smaller than the holes in the filters. If you knew you were going to be somewhere with water with nasty chemicals in it and you knew what they were you could use an activated charcoal pack or whatever is appropriate for those chemicals to remove it after it has been through the straw so you aren’t making a habitat for potentially nasty microorganisms.

Before using the LifeStraw or other similar devices, I suggest to pre-filter the water through a cloth (T-shirt or whatever) or carry some disposable coffee filters with you. This will remove a bunch of the particulate and extend the service life of the LifeStraw filter.

Well sir, I feel like I owe you a debt of gratitude for “taking one for the team” so to speak. Last year I really started prepping. Like a whole lot of other people in this country I FEEL like something is headed our way. Something not so good. Don’t know exactly what it may be, but I just can’t shake that feeling. In my preps I’ve purchased several of these Lifestraws for every member of my family who currently reside with me. In my house that is. I’ve also purchased more in case others show up after some unforeseen event. I’ve never used one I admit that, but I was trusting that they work, until I ran across your video. I gotta admit, before I saw the results, I was questioning these HARD. But now that I’ve seen the results I feel so much better. The weight of that decision, DEPENDING on these to keep me and my family safe and alive, THAT is a lot of responsibility and weight on my shoulders. So THANK YOU for proving to me, and affirming to me that these are going to help get us through if the need ever should arise. God Bless you and again, Thank You.

He put a lot of scummy pond water through the gizmo and into his own stomach without getting ill. His vids showed some scary looking water. He already knew the device was effective from lab tests but he want to show people that it worked safely. The issue was how to either clean or replace the filtres.

This isn’t much of a test. It’s a cool science experiment. The life straw does not claim to remove viruses, and this microscope can’t see viruses. In the case of a hurricane, you should expect water might be contaminated with viruses from human waste, and salt. Neither is removed by the life straw. Worse, the Life straw’s design makes it hard to filter then disinfect using iodine or chlorine. Please consider switching to a method that allows you to filter, then disinfect. A single gallon of bleach will allow you to disinfect about 1000 gallons of filtered water. Edit: I’m talking about the LifeStraw Personal. The device people think of as the LifeStraw. There are others in the line that do work better.

My brother has one. I have a sawyer mini which is very similar. Although slow(I think the filter claims 0.1 micron?)

The thread is a standard water bottle thread so you can use discarded plastic water bottles in a pinch. Water was always the heaviest thing in my bag, not any more. Great device!

[@CarlKem]

This is good to know. Though, from my experience in both the back country and rural areas, I would find and another filter source to run the water through first. Something like activated charcoal (not the Kingsford style, but something from a camp fire). Even the LifeStraw has a lifespan. Pre-filtering the water will make the LifeStraw last longer.

Very interesting to see such a change but for reliable bacteria detection to be seen you need to stain the sample and go to greater magnification. Viruses would not be seen in the sample with the rig you are using as they are far too small compared to bacteria. I would still chemically treat that water if I could. Trusting a filter that you have no way to verify it's condition in the field is a risk. But again very good results in terms of clarifying the water.

One question still to be answered: What gives the color of the filtered water? Is it a dissolved chemical or something else?

[@hoon_sol]

My guess would be that the color is primarily due to dissolved mineral salts. Small enough clusters of metals would also manage to make it through, so it could even potentially contain some heavy metals. Various molecules are also small enough; there's a big difference between single cells and single atoms or small molecules. The filter size is ~0.2 microns, i.e. 0.2 µm (micrometer, a millionth of a meter), whereas atoms are more on the order of ~0.2 nm (nanometer, a billionth of a meter), i.e. a 1000-fold difference (three orders of magnitude).

[@augustinchenault9981]

What could be the source of the slight green color still present in the clean water?

Likely whatever minerals and other things are dissolved in the water, as those molecules are too small to be filtered out by the lifestraw.

[@Deltarious]

A note about the intro: Though there were times before I had learnt that I *did* wonder about the mechanism of action and that it seemed almost like magic to me, there was never a time when I wondered if it actually worked.

probably released chlorophyll from dead algae in the pond water. After all molecules of chlorophyll are MUCH smaller than any bacteria so would escape. Thankfully chlorophyll is the stuff that makes plants green, and is actually nutritious for humans since its also in all the vegetables we eat, so it would be harmless in filtered water. I imagine if you were to run the life straw's flitered water though a carbon filter that would be taken right out.

​@@throbbinwoodofcoxley6830Rannins shouldn't hurt you. The fish get by well w them. In fact, you put Mopami wood in there where there's lots of limestone.

Hi, would you check salt water after filtration through lifestraw? It still has salttaste after filtration.

[@manofsteel1107]

It’s salt it disloves in water I belive dissolve is beyond the 0.02 microscopic hole probably like 0.0

[@MAGNITUDE16]

Don’t keep drinking it, you can’t just filter salt water out because it’s dissolved in water. 0.02 microns is not enough to filter salt. You can’t boil salt water either you have to distill it or evaporate it.

[@keithfillinger3182]

You need a different way to filter salt out of water. A solar still, or regular distilling device work. One other approach I heard about involves two containers and a wicking material. There also needs to be a slight difference in elevation between the two containers. The top container should have the salt water in in it. The bottom container is an empty collection conainer. You would take an absorbant material (cotton shirt, etc.) and run that from the top container to the bottom container. The cotton will wick the water from the top container to the bottom one leaving the salt behind. It works better on a hot sunny day, and it is a slow process. I would still treat the water for viruses etc. prior to drinking it.

Lifestraw doesn't filter sea water or toxic water.

Wow, it really works! Wonderful information. Good video.

Love it, been looking for exactly this content about these water bottle filters

[@duradim1]

You should get a Badge of Courage. You are the first person I've seen who actually drank the filtered water. Even people who sell these things never drink the water after being filtered on a KZbin commercial.

Notice that his last video was the one after this one, both two years ago. Oh, oh.
