Overview
This replacement cartridge is made for hunters and backcountry travelers who rely on a GRAYL GEOPRESS Water Purifier for drinking water in the field. It is designed to remove waterborne pathogens while also improving water flavor, odor, and clarity. The cartridge is rated for about 350 uses, or roughly 65 gallons, though that lifespan can decline when treating water with heavy silt, sediment, or tannins. As the cartridge nears the end of its service life, press time increases, and replacement is recommended once it reaches 25–30 seconds.
