Give your GeoPressA(R) 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 GeoPressA(R) One-Way Valve now ships pre-installed in every GeoPress.
