Grayl Geopress Replacement Purifier Cartridge

Replacement purifier cartridges for the GEOPRESS are designed to last 350 cycles (65 gal/250 L). 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 (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 
• Improves taste, smell and clarity
• Ion Exchange & Activated Carbon: Inside the purifier cartridge, non-woven ceramic fibers block particulates and provide structure for two technologies: (1) positively charged ions (i.e. molecular magnets) and (2) powdered activated carbon. As dirty water is forced through the purifier media, ion exchange permanently binds pathogens (i.e. virus, protozoa, bacteria). Activated carbon adsorbs pesticides, chemicals, heavy metal, flavors and odors
• Clean safe water Once purified; water is ready to chug, sip or store for later. Purify water, anywhere in the world
