LifeStraw Mission Portable Water Filter

The LifeStraw Mission gravity powered water purifier removes 99.9999% of bacteria, 99.99% of protozoa, and 99.999% of viruses, while purifying an impressive 18,000 liters of water (4,750 gallons). Simply fill the BPA-Free bag, hang, and enjoy clean, purified drinking water. It’s Ideal for camping, group hikes, expeditions, and more.

LifeStraw Mission uses a highly efficient method of purification that requires no chemicals, batteries or moving parts. Water poured into the purifier moves down the tube, while being forced through narrow hollow fibers. Clean water exits through tiny pores in the walls of the hollow fibers, but bacteria, viruses, protozoa and other contaminants are trapped inside and are flushed out by backwashing.
