Overview

The Oneisall PW04 six-pack replacement filters are designed for the 3.5L cordless cat fountain. They fit specific models (B0DNJT76WJ, B0DMF2LH3Y, B0DSJ9F3M2) and are not compatible with PW03. These filters use a multi-stage filtration system with activated carbon to help capture hair, debris, and other impurities, supporting cleaner water for your cat’s drinking bowl. While results can vary by usage, many households notice a fresher-tasting water and easier maintenance when old filters are replaced regularly.

What’s included

  • 6 PW04 replacement filters for the 3.5L cordless cat fountain

Each filter is designed to work within the PW04 ecosystem, helping you refresh the fountain quickly so you can spend less time on upkeep and more time with your pet.

Key benefits you may notice

  • Activated carbon filtration helps reduce odors and concentrates impurities before water reaches your pet.
  • Filtration targets common fountain debris like hair and fine particles, supporting smoother operation and easier cleaning.
  • Regular replacement can help maintain water clarity and a more inviting drinking bowl for your cat.
  • Compact, six-pack design ensures you have replacements on hand to keep the fountain performing well.

How to use and maintain

Open the fountain, remove a spent filter, and snap in a fresh PW04 filter. Rinse the new filter briefly if recommended by your setup to remove any loose particles. Reassemble, refill with fresh water, and monitor the water clarity over the next days.

Care tips

  • Store extra filters in a cool, dry place to preserve material integrity.
  • Replace filters according to your fountain’s routine or when you notice changes in water clarity.
  • Keep the fountain and its filters clean to extend the life of the unit and maintain water taste.
