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.

Note: the GeoPress® One-Way Valve now ships pre-installed in every GeoPress.

Overview

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.

Excellent addition

I don’t use this for drink mixes, but I bet it would work well for that solo. My primary use for this is so I can use my Grayl as a primary water container without getting me filter wet if I have a safe source of water. It made my Grayl a much more EDC
