Boost your GeoPress! 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 or other flavored liquids.
 
Note: the GeoPress® One-Way Valve ships pre-installed in every GeoPress Bottle.
 
Replacement purifier cartridges for the GeoPress are designed to last 350 cycles (65 gal. / 250L).  Lifespan will decline when purifying water with high levels of silt, sediment or tannins.
 
Cartridge press time increases towards the end of the cartridge lifespan; when press time reaches 25-30 seconds, the cartridge should be replaced.  Cartridge continues to protect, even as press time increases.
