LifeStraw: This straw turns dirty water into drinking water

Posted by Earthr.org Content Team on 21 Aug, 2018

LifeStraw uses a hollow fibre membrane that doesn't require chemicals such as chlorine or iodine. Using high pressure upon sucking through the straw, the water is forced through the narrow fibres, trapping bacteria, protozoa and other contaminants, which are then flushed out by backwashing. 

It removes 99.9999% waterborne bacteria (including E.coli), 99.9% of protozoan parasites, and other health issues such as Hepatitis E, Typhoid Fever and Dysentery. Turbidity (muddiness) is also reduced down to 0.2 microns3. A game-changer for those living in poverty, or people traveling in areas where the water supply is polluted.
