Boost your GeoPress! The GeoPress cartridges were redesigned in April 2023 with a new core and flow channels to accommodate a one-way valve for use with electrolytes, drink mixes and other flavoured liquids.

The replacement cleaning cartridges for the Grayl GeoPress are designed to last 350 cycles (250 l / 65 gal). The service life is shortened when purifying water with a high content of sludge, sediments, or tannins. The cartridge press time increases towards the end of the service life; when the press time reaches 25–30 seconds, the cartridge should be replaced.

The GeoPress Purifier cartridge will continue to protect even as the press time increases.
