Give your UltraPress® a boost! Add a One-Way Valve to make it possible to add electrolytes, drink mixes and other flavored liquids into an UltraPress.

Note: an UltraPress® One-Way Valve now ships pre-installed in every UltraPress.

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

  • 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 UltraPress or UltraPress Ti Bottle: cocktails, cocktails, beer, seltzer water and juice.
  • Four 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 UltraPress 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.
