Grayl Ultrapress Purifier Cartridge

Replacement purifier cartridges for the UltraPress™ 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 seconds, the cartridge should be replaced. Cartridge
continues to protect, even as press time increases.
