About this product

Enhance your GeoPress experience! Updated in April 2023, the Grayl GeoPress Cartridge feature a redesigned "core" and "flow channels" that include a One-Way Valve, allowing you to safely use electrolytes, drink mixes, and other flavored liquids.

Note: the GeoPress® One-Way Valve ships pre-installed in every GeoPress Bottle.

These replacement purifier cartridges for the GeoPress offer up to 350 uses (65 gallons / 250 litres).

While lifespan may decrease with water containing heavy silt, sediment, or tannins, the cartridge remains effective throughout.

As the cartridge ages, pressing time will lengthen—once it hits 25-30 seconds, it’s time for a replacement.

Even with slower press times, protection continues.
