Filter freshwater on demand — 0.00000039-inch hollow-fiber membrane, up to 1,321 gallons per straw, without chemicals, batteries, or electricity.
Why Is This Perfect for You?
✔ Fine hollow-fiber filtration: The 0.00000039-inch hollow-fiber membrane mechanically filters fine sediment, microplastics, and cloudiness from freshwater. Filtration is immediate and requires no chemicals, batteries, or electricity, with no chemical aftertaste.
✔ Fits standard threaded bottles: Dual 1.1-inch threads fit standard threaded bottles and connect to compatible squeeze bags and hydration bladders. The straw can also be used directly in freshwater, without a bulky hand pump.
✔ Compact with high capacity: Each compact 5.3 × 1.2-inch straw is rated to filter up to 1,321 gallons. The backwash-friendly design helps clear trapped sediment, and the two-straw bundle provides up to 2,642 gallons of combined capacity.
