The Lifestraw is a convenient portable water filtration device that I often use during hiking and camping trips. They say it will filter 99.9999% of waterborne bacteria and protozoan parasites and reduce turbidity down to 0.2 microns. I always used it in freshwater sources that appeared to be fairly clean. In this test, I show what happens when using the Lifestraw in a very turbid stagnant muddy puddle. Would you drink this water? Follow me on Facebook.com/chadzuber Follow me on Instagram @zuberchad
