How to replace the water pitcher filter cartridge

Replacing the filter cartridge in your aquabliss water pitcher is a straightforward process that takes around 15 minutes, including the soaking time. Follow the steps carefully — the soaking and flushing steps are important for making sure your water tastes clean and clear from the first use.

How long do the XL cartridges last?

Each XL filter cartridge is designed to last up to 80 gallons or 4 months — whichever comes first. Usage varies significantly between households. If you fill and filter the full pitcher multiple times a day, or use the pitcher as your primary drinking water source for several people, you may reach the 80-gallon limit before the 4-month mark. If you notice the filtration slowing down or a change in water taste before 4 months, it's likely time to replace the cartridge.

Step-by-step: how to change the cartridge

IMPORTANT: always use cool or room temperature water throughout this process. Hot water can damage the filter media inside the cartridge.

  1. Wash your hands before handling the new cartridge.

  2. Remove the new cartridge from its sealed packaging.

  3. Fill the pitcher base with cool or room temperature water and place the cartridge upright in the water. Leave it to soak for 10 minutes. This activates the filter media and removes any residual carbon dust before the cartridge goes into use.

  4. After soaking, remove the cartridge and rinse the top surface under running water for 10 seconds.

  5. Press the cartridge firmly down into the tube at the base of the Reservoir unit until you feel it seat securely. A poor seal here can allow unfiltered water to bypass the cartridge.

  6. Attach the Reservoir lid.

  7. Fill the Reservoir with cool or room temperature water and allow all of it to filter through into the pitcher below. This first filtered water should be discarded.

  8. Refill the Reservoir and allow it to filter through again. Discard this second batch as well.

  9. The third batch of filtered water is ready to drink.
