Key benefits you may notice

Multi-layer filtration targets hair, debris, and sediment that can accumulate in a cat fountain. It also aims to improve taste and reduce odors and impurities from water. This can help keep the fountain inviting while your cat sips at its own pace.

Usage and maintenance

Optimal setup starts with proper pre-use preparation. Soak the filter for 5-10 minutes and rinse for 30 seconds to minimize carbon dust. After installation, monitor flow and water clarity and top up as needed.

Recommended replacement schedule

• Summer months: replace every 1-2 weeks
• Winter months: replace every 2-4 weeks
• Multiple pets: expect more frequent changes and routine fountain cleaning

Care and installation tips

• Handle components with clean hands to avoid introducing oils
• Store spare filters in their sealed packaging until ready to use
