Replacement purifier cartridges for the Geopress are designed to last 350 cycles (65 gal / 250 L). 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. However, the cartridge continues to protect, even as press time increases.
