Why Is This the Right Fit for You?
✔ Fine hollow-fiber filtration: The 0.00000039-inch hollow-fiber membrane removes 99.9999% of waterborne bacteria and 99.99% of protozoan parasites, including E. coli and Giardia. It does not remove all viruses or make chemically contaminated water safe.
✔ Lightweight and compact: At less than 2 ounces and 7 inches long, it fits in a pocket or pack and reduces the need to carry bulky water containers. It is compatible with standard 1.1-inch water bottles and hydration bladders.
✔ Long-lasting filtration capacity: Filter up to 1,057 gallons, with a 5-year shelf life for extended use. Backflushing after use helps clear trapped particles and maintain filter life.
