UltraPress One way Valve
Enjoy a drink-mix no matter where your adventure takes you.
Replace electrolytes lost in sweat and hydrate quickly.
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.
