Key Features

• Made with a cotton layer, ion-exchange resin, and activated carbon, which work together to ensure the purity of the water
• Triple filtration system makes it highly efficient in removing residue, hair, harmful substances, bad tastes, and odours from the water
• Contains 8 filters and 8 foam filters
• Compatible with pet fountains and automatic water dispensers (sold separately)

Note: Please soak filter replacements with water for 10 minutes and rinse it under running water completely before use. In winter, 1 piece filter can purify pet fountain water for 2 to 4 weeks for cats. While in summer, the filter should be replaced once or twice every two weeks since pets use the fountain more often throughout hot days. If it is for multiple cats, frequently changing is needed.
