Upgrade your GeoPress! GeoPress cartridges were redesigned in April 2023 with a new core and flow channels that enable use of a one-way valve for use with electrolytes, sports drink mixes or other flavoured liquids.

Note: The GeoPress® one-way valve comes pre-installed in every GeoPress bottle.

Replacement purification cartridges for GeoPress are designed to last 350 cycles (65 gal. / 250 l). Lifespan will decrease when purifying water with high mud, sediment or tannin content. Cartridge press time lengthens towards the end of cartridge life; when press time reaches 25 - 30 seconds, the cartridge should be replaced. The cartridge continues to protect even as press time lengthens. Compatible with the one-way silicone valve for electrolytes and sports drink mixes.

Features:

• Removes waterborne pathogens (viruses, bacteria, protozoan cysts) including rotavirus, hepatitis A, norovirus, giardia, cryptosporidium, E. Coli, cholera, salmonella, dysentery and others
• Filters solid particles (e.g. mud, microplastics etc.); ultra-fine activated carbon effectively adsorbs chemicals (including PFAS & VOC), pesticides, heavy metals, flavours and odours
• Improves taste, odour and clarity

Technical specifications:

• Active technology: Electroadsorption and ultra-fine activated carbon
• Compatibility: works with GeoPress® one-way valve for electrolytes and sports drink mixes
• Chemical-free: Yes

• Filters: solid particles (e.g. mud, microplastics etc.); activated carbon effectively adsorbs chemicals, pesticides, heavy metals, flavours and odours
• Fast flow rate: 8 seconds per 24 oz (5 litres/minute)
• Cartridge lifespan: rated for 350 cycles (65 gal. / 250 l), when "press time" reaches ~25 seconds (or three years have passed since first use), it is time to replace the purification cartridge
• Cartridge durability: stored under proper conditions, an unused (and airtight) purification cartridge has a lifespan of 10 years
