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.

  • Enjoy a drink-mix no matter where your adventure takes you. Replace electrolytes lost in sweat and hydrate quickly.
  • Try these in your drink-mix ready GeoPress: cocktails, cocktails, beer, seltzer water and juice.
  • Six duck bill valves prevent back flowing of water (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 care and use between uses. Thoroughly dry a wet Cartridge by pressing into an empty (no water) Outer Cup, then dump any excess water. Remove the One-Way Valve and allow Cartridge to air-dry thoroughly (depending on humidity it will take 2-4 days to completely dry). Clean and dry the One-Way Valve, then reassemble GeoPress Bottle.
  • One-way valve is dishwasher safe. Regularly wash Valve between uses to remove smell and residue left behind from powders or other beverages. Hand wash with warm, soapy water or place in a dishwasher. Do not expose Cartridge to soap or cleaning agent of any kind.
  • Size: 2.25" (5.8 cm) H x 1" (2.6 cm ) W
  • Weight: .42 oz (12 g)
  • Compatibility. Only compatible with GeoPress® bottles and cartridges sold on Grayl.com in Spring 2023 that feature a 2nd generation cartridge with horizontal flow channels (stacked in groups of six). 1st generation cartridges will not be able to accommodate a valve.
  • BPA-Free Materials. Made from food-grade silicone.
  • Origin. Designed in USA, made in China.

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

Great to have but turns out they were already included in my extra filters and the ones in my bottles. I should have paid attention more.

An outstanding upgrade to an outstanding upgrade
When I expanded my water procurement methodology to include the Geopress, I didn't foresee a future product improvement to be this significant of a game-changer. I really blew it on that assumption. Since my Grandpa began teaching me to be self-reliant
