The replacement purifier cartridges for the UltraPress™ are engineered to serve you for up to 300 cycles, equivalent to 40 gallons (150 liters) of water purification. However, if you're purifying water with high silt, sediment, or tannin levels, the cartridge's lifespan may decrease. As the cartridge nears the end of its life, the press time will increase. When the press time hits 25 - 30 seconds, it's time to swap it out. Even as the press time goes up, the cartridge still offers reliable protection.

Using your Grayl UltraPress Purifier Cartridge is a breeze. First, make sure the cartridge is properly installed in your UltraPress™ device. Then, pour the water you want to purify into the container. Press down on the purifier, and clean, safe water will come out. Keep an eye on the press time. As the cartridge gets older, the press time will increase. When it takes 25 - 30 seconds to press, it's time to replace the cartridge.
If you're purifying water with a lot of silt, sediment, or tannins, the cartridge might not last as long as usual. Try to pre - filter really dirty water if possible. Store your unused cartridges in a cool, dry place. They can last up to 10 years if kept air - tight. And don't worry about chemicals, as the cartridge is chemical - free and made from safe, food - grade materials.
