Replacement purifier cartridges for the UltraPress® (and Ultralight) are designed to last 300 cycles (40 gal. / 150L) 3L/Min.  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.

FEATURES

• Removes waterborne pathogens (virus, bacteria, protozoan cysts), including Rotavirus, Hepatitis A, Norovirus, Giardiasis, Cryptosporidium, E. Coli, Cholera, Salmonella, Dysentery and more 
• Filters particulates (i.e. silt, microplastics, etc.); ultra-powdered activated carbon effectively adsorbs chemicals (including PFAS & VOCs), pesticides, heavy metals, flavors, and odors
• Improves taste, smell and clarity
