In April 2023, we redesigned our cartridges to accommodate a one-way valve. This is a significant upgrade that includes a new "core" as well as "flow channels" allowing electrolytes, drink mixes, and other flavored liquids to be added to the GeoPress.
A feature no other filter bottle can offer, the GeoPress® one-way valve allows electrolytes and sports 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 beverages such as juices, sparkling water, mocktails, and cocktails.
Note: the GeoPress® one-way valve now comes pre-installed in every GeoPress.
Main features
- Enjoy a mix of beverages, no matter where your adventure takes you.
Replace electrolytes lost in sweat and hydrate quickly.
- Try them in your drink-ready GeoPress: cocktails, mocktails, beer, seltzer water and juice.
- Six duckbill valves prevent water backflow (or other beverages) through the cartridge while also allowing clean filtered water to pass through the cartridge into the inner press.
- Easy to remove for maintenance and use between uses. Thoroughly dry a wet cartridge by pressing it into an empty outer cup (without water), then discard any excess water. Remove the one-way valve and allow the cartridge to air dry completely (depending on humidity, it will take 2 to 4 days to dry completely). Clean and dry the one-way valve, then reassemble the GeoPress bottle.
- The one-way valve is dishwasher safe. Regularly wash the valve between uses to remove odors and residue left by powders or other beverages. Hand wash with warm soapy water or place in the dishwasher. Do not expose the cartridge to soap or any cleaning product of any kind.
