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.

• Removes waterborne pathogens(viruses, bacteria, protozoan cysts), including Rotavirus, Hepatitis A, Norovirus, Giardiasis, Cryptosporidium, E. Coli, Cholera, Salmonella, Dysentery and more

• Filters: particulates (sediment, microplastics) and many chemicals, pesticides, and heavy metals
