GRAYL UltraPress Purifier Cartridge - Black

Replacement purifier cartridges for the UltraPress (and Ultralight) are designed to last 300 cycles (40 gal/150L). 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 sec, the cartridge should be replaced. Cartridge continues to protect, even as press time increases.
