Give your GeoPress® a boost! In April of 2023, we redesigned our Cartridges to accommodate a One-Way Valve. It's a significant upgrade that includes a new "core" plus "flow channels" making it possible to add electrolytes, drink mixes and other flavored liquids into GeoPress.

A feature no other drink-thru filter bottle can deliver, the GeoPress® One-Way Valve allows electrolytes and sport drink mixes to be added to clean purified water without compromising the integrity of the filter. Also allows a GeoPress to be used with a variety of flavored drinks such as juice, bubbly water, mocktails and cocktails.

Only compatible with 2nd Generation cartridges first sold in April 2023 that include a new "core" and "flow channel" design (horizontal vents). 1st Generation cartridges are not compatible with the Drink-Mix Valve.

01

INSTALLATION

Using your thumbs firmly press and seat the One-Way Silicone Valve into the cartridge. Insert finger into valve if needed.

02

SEATING & SECURING

Protect the cartridge media by double-checking that the valve is seated and secured. Check proper installation visually, by ensuring the rim of the silicone is flush with topside, and that the base of the Valve is flush with Cartridge floor.

03

REMOVAL

Using your fingers, firmly pinch the top of the One-Way Silicone Valve, then firmly grasp and remove the Valve from the Cartridge.
