✔ Four-stage mechanical filtration: A pre-filter traps sediment, mud, and organic debris before water passes through the hollow-fiber membrane with a 0.00 in pore size. It reduces up to 99.9% of bacteria and protozoa, as well as microplastics, without electricity or chemical tablets.

✔ Filters up to approximately 1,800.5 gal: Each filter can treat up to approximately 1,800.5 gal of water under normal operating conditions, supporting repeated use and long-term emergency preparedness.

✔ Compact, maintenance-free storage: Weighing less than 2.1 oz, the filter fits in emergency kits and backpacks. It has no expiration date and needs no regular maintenance or storage rotation, batteries, electronics, or moving parts.
