These lightweight emergency water filters are a hard-to-argue-with addition to any foraging kit due to their incredible ability to remove a wide range of microbial and metal pollutants from water. Using a revolutionary five-stage filter system that combines three micro filters, activated charcoal, and a proprietary alloy (which attracts and removes heavy metals and other pollutants), these pocket filters can be used daily for up 6 months and still remain effective!

See the Specifications tab for details on filtration efficacy.
