Geopress Purifier Cartridge Steel Blue/TNF Black the Classic Hike Zero CushionReplacement 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.
