OVERVIEWReplacement purifier cartridges for the GEOPRESS are designed to last 350 cycles (65 gal. / 250L). 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

TECH SPECS

• Active Technology: Electroadsorption and ultra-powdered activated carbon.
• Chemical-free: Yes
  
• Size: 2.9″ (7.3 cm) H x 3.1″ (7.8 cm) W
• Weight: 3.8 oz (108 g)
  
• Removes: waterborne pathogens (99.99% of viruses, 99.9999% of bacteria, 99.9% of protozoan cysts), including Rotavirus, Hepatitis A, Norovirus, Giardiasis, Cryptosporidium, E. Coli, Cholera, Salmonella, Dysentery and more
• Filters: particulates (i.e. silt, microplastics, etc.); activated carbon effectively adsorbs chemicals, pesticides, heavy metals, flavors, and odors
