Owner's Manual & FAQs

Question: How do I replace my filter?

Answer: Pull the Filter Cartridge Handle straight up slowly, listening for water dripping from the filter. With the Cartridge fully removed, flip the Cartridge Door open. Remove the filter, and either: Flip top to bottom to ensure the top does not dry out OR Replace with a new filter. To prolong the life of your Wicking Filter, turn it over each time you fill the Water Tank. This will keep the top of the Filter from drying out and will help the Filter to age more evenly. If you notice the Filter getting hard, you may soak it in cool water to loosen mineral buildup. This will temporarily improve performance of the Wicking Filter until a replacement Filter is purchased. DO NOT attempt to clean the Wicking Filter with vinegar, soap or any chemical solutions. Doing so may damage the Filter.


Question: When do I change my filter?

Answer: It is recommended you change your Wicking Filter every 30-60 days depending on water quality and usage. If you have hard water, you may need to replace your Filter more frequently.

Change your Filter if you notice:

  • The Filter is hard and crusty
  • The Filter starts to give off an odor
  • Moisture output is decreased
