A feature no other drink-thru filter bottle can deliver, the one-way valve for the UltraPress® allows electrolytes and sports drink mix to be added to clean purified water without compromising the integrity of the filter.
- 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
