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. Plus, these cartridges are compatible with the One-Way Silicone Valve, perfect for use with electrolytes and drink mixes.

Features:

• Filters particulates (i.e. silt, microplastics, etc.); ultra-powdered activated carbon effectively adsorbs chemicals (including PFAS & VOCs), pesticides, heavy metals, flavours, and odours
