Aquamira Backcountry SRS IV Replacement Filter – Field-Replaceable Water Filtration

The Aquamira Backcountry SRS IV Replacement Filter keeps your Backcountry Series water filtration system operational in extended backcountry trips. Designed for hunters, backpackers, and preppers who need reliable access to clean water beyond resupply points, this replacement cartridge restores filtering capacity without replacing the entire system.

The SRS IV filter cartridge uses a 0.1-micron hollow fiber membrane to remove bacteria, protozoa, and sediment from natural water sources. Each filter processes up to 150 gallons depending on water quality and maintenance. The compact design packs light and installs quickly in the field—critical when you're days from trailheads or operating in remote hunting areas. Rinse periodically to maintain flow rate.
