Why choose us?

Activated carbon is responsible for purifying the water and removing odors and impurities; cotton may be used for physical filtration to intercept hair and particles; resin may be softening the water and reducing limescale. It can effectively promote cats to drink water and prevent urinary diseases.

How to Use?

Place the filter in water for 2 minutes, then remove and rinse under running water for 30 seconds.We recommend that the water pump in the cat water dispenser be deep cleaned and the filter replaced once every 2 weeks.

Customers find the water dispenser filters effective at keeping water fresh and clean, and consider them good value for money. They appreciate the drinking performance, with one customer noting their cat drinks more than before. The filter replacement aspect receives mixed feedback – while customers find them easy to use, they need to be changed every two weeks.
