Grayl GeoPress® Purifier Cartridge

Keep your GeoPress performing at its best with replacement purifier cartridges built for fast, reliable clean water wherever you go. Each cartridge is designed to last up to 350 cycles or 65 gallons (250L), giving you dependable filtration for travel, trail use, emergency kits, and everyday carry.

As the cartridge nears the end of its lifespan, press time will begin to slow. When it reaches 25–30 seconds, it’s time for a replacement. Even as flow slows, the cartridge continues to protect, giving you added confidence until you swap in a new one. It’s also compatible with the One-Way Silicone Valve, so you can keep using electrolytes and drink mixes with your GeoPress setup.
