The LifeStraw Mission is a gravity-powered water purifier employing an award-winning technology that requires no chemicals, batteries or moving parts. The LifeStraw Mission removes 99.9999% of bacteria, 99.99% of protozoa, and 99.999% of viruses. The larger capacity of the Mission water purifier is ideal for providing clean water to multiple people, and is designed for camping, hunting, and other group or family activites, as well as disaster and emergency survival prep kits. The reservoir can be filled from nearby lakes, ponds, rivers, or streams and suspended from a tree or other sturdy support. Gravity moves water down the hose to the filter's advanced ultrafiltration membrane. Clean water exits through 0.02 micron pores in the walls of the hollow fibers, but bacteria, viruses, protozoa and other contaminants are trapped inside and are flushed out by backwashing.
