The Flex multi-use water filter features a durable TPU nylon soft bottle that houses a compact microfilter membrane with an additional activated carbon + ion exchange filter. The microfilter membrane provides up to 2,000 litres of clean drinking water - enough for an individual for over 2.5-years. The activated carbon + ion exchange filter that reduces lead, chlorine and bad odours for improved taste. The activated carbon filter lasts up to 100 litres and can be removed when taste poses no issue - for instance when drinking from an alpine source.

The LifeStraw Flex uses a microfilter made of hollow fibre membrane technology. These membranes are made of small straws that contain microscopic pores of 0.2 microns in diameter that allow clean water to pass through while preventing larger bacteria, parasites, microplastics, and other forms of turbidity from reaching the clean water chamber at the other end. The result is safe drinking water flows into a clean chamber for consumption while contaminants are blocked.

LifeStraw’s membrane microfilters are capable of removing 99.999999% (log 8) of bacteria (including E. coli), 99.999% (log 5) of parasites (Giardia, Cryptosporidium, etc.), and 99.999% (log 5) of microplastics. The LifeStraw Personal does not filter viruses and should be used in areas/conditions where the water source is known to be free of human contamination.

The LifeStraw Flex has been tested all over the globe for a proven solution to the problem of finding safe drinking water in regions where clean water sources are in short supply. Using a LifeStraw water filter on your trip also helps reduce the amount of bottled water consumed which reduces the amount of plastic waste.
