Grayl GeoPress® Replacement Purifier Cartridge

Replacement purifier cartridges for the GeoPress® are designed to last 350 cycles (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.

Cartridges continue to protect, even as press time increases.
