Aquam Backcountry Srs Iv Rplc Fltr

The Aquamira Backcountry Series IV replacement filter is a compact, lightweight cartridge built for backcountry hunters, backpackers, and anyone who needs reliable water treatment far from the trailhead. Designed to work with Aquamira Series IV systems like the Frontier MAX and Shift Bottles, this ultralight filter adds less than 1 ounce to your pack while delivering the cleaning power to keep you hydrated on extended trips into the field.

This replacement filter gives you the flexibility to swap cartridges as needed without replacing your entire system. Whether you're filtering from a remote alpine lake or a sketchy backcountry creek, the four-stage filtration process handles the threats you actually face in the backcountry. It removes 99% of viruses, bacteria, and cysts—the contaminants most likely to ruin a hunt or expedition. With a 100-gallon rating per cartridge, you get solid capacity before needing to rotate in a fresh filter.

The Series IV modular design means you're not locked into a single bottle or system. If your primary hydration bottle gets damaged or you want to upgrade to a different Series IV container down the road, your filters stay compatible. That flexibility—combined with minimal pack weight and genuine backcountry-grade filtration—makes this a practical choice for hunters and backpackers who demand reliability without the bulk.
