The ability to use as a personal water purifier or as a filter in hydration bladder or gravity water system makes LifeStraw Flex a versatile water purifying tool. The kit includes the 2-stage advanced filter system and a collapsible bottle. LifeStraw Flex can be used as a personal straw filter to drink straight out of a lake, or with the collapsible bottle filled with water. Flex also fits most hydration bladders and gravity systems, so you can easily transform those into fresh water sources.

LifeStraw Flex filter system is based on a 2-stage filtration. At the first stage the hollow fibre membrane removes most bacteria, parasites, and microplastics. At the second stage the replaceable carbon capsule reduces lead and other heavy metals, chlorine, organic chemical matter, and bad odour and taste. The hollow fibre membrane has a 2000 litre lifetime capacity, while the replaceable carbon filter has a capacity of 100 litres (3 months in frequent use).
