LIFESTRAW FLEX GRAVITY BAG Water Filter - 3.7 Liters

How does the LIFESTRAW FLEX GRAVITY BAG water filter work?

The Flex Gravity Bag developed by LIFESTRAW is a water filter that works on the principle of gravity: non-potable water naturally flows through a very fine carbon filter. The large capacity water filter can be suspended in bivouac to the camping tent.

The characteristics of this water filtration system

This water filter has a filtration efficiency of up to 2,000 Liters. The carbon filter is designed to filter up to 100 liters before needing to be changed. The water filtration by the Flex Gravity Bag filter eliminates 99.999999% of bacteria such as E. coli responsible for diarrhea. 99.999% of parasites are also destroyed through water purification. The Flex Gravity Bag is very compact and usable in all circumstances. It requires no energy input and does not pollute the environment.

A water filtration system that goes well beyond current standards

Indeed, whether it's for the reduction of lead and other heavy metals (NSF53 standard), the reduction of chlorine (NSF42 standard), or the reduction of bacteria and parasites (US EPA standard), the Flex Gravity Bag exceeds the required thresholds.

With its two-stage filtration system, the Flex Gravity Bag filter eliminates:

• • • 99.9999% of bacteria (cholera, salmonella, E.Coli?)
    • 99.99% of protozoan parasites (giardia,
      cryptosporidium?) that can contaminate water
    • Reduces chlorine and chemical agents (pesticides, herbicides, VOCs), as well as bad taste and odors thanks to its activated carbon capsule.
