Grayl Ultralight Replacement Purifier Cartridge

Campmor says:
Replacement purifier cartridges for the UltraPress(TM) 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.Removes waterborne pathogens (viruses bacteria protozoan cysts) including Rotavirus Hepatitis A Norovirus Giardiasis Cryptosporidium E.
