Why Is This Water Filter Perfect for You
✔ Fine ultrafiltration: The 0.000000394-inch ultrafiltration membrane is stated to remove 99.9999% of bacteria and waterborne pathogens, along with sediment and harmful particles. It helps provide clean drinking water from natural sources where municipal treatment is unavailable.
✔ 2.64-gallon batch capacity: Process up to 2.64 US gallons per filling for multiple users or extended use. The larger batch capacity means fewer interruptions to refill during group trips or emergency situations.
✔ Power-free and portable: Gravity does the filtering, with no electricity, batteries, or pumping required. At 1.10 lb, the compact design is easy to carry in a backpack or emergency kit and has no moving mechanical parts.
