Pet Water Fountain Filters replacement Cartridges for the USB

Pet Water Fountain Filters are replacement cartridges designed to help maintain your compatible USB pet water fountain and keep your pet's drinking water flowing through the fountain's filtration system. This convenient 6-pack provides multiple replacement filters, making it easier to maintain a consistent cleaning and replacement routine for your pet's water fountain.

Each replacement cartridge features a 3-layer filtration design intended to help filter impurities and unwanted particles from the circulating water. Regularly replacing the filter cartridge can help maintain the performance of your compatible pet water fountain while supporting a cleaner and fresher drinking-water environment for your dog or cat.

Refill for the USB Pet Water Fountain Filters — not a fountain

This listing is a pack of 6 replacement filter cartridges. It fits one product only: the MATERA PET Automatic USB Pet Water Fountain. If you do not own that fountain yet, buy the fountain — it already comes with a filter fitted.

⚠️ These cartridges do not fit our 101 oz fountain. That model takes its own 6-pack, here.

Why Replace Regularly

• Cleaner water — removes hair, food residue and sediment
• 3-layer filtration — cotton pre-filter, activated carbon and nano-bubble cotton, together softening the water and cutting odors
• Protects the pump — a fresh filter stops debris from clogging and burning out the motor
• Encourages drinking — better-tasting water means better hydration for cats and dogs
• 6 months of value — six cartridges, one full replacement cycle

Common Mistakes

• Ordering the wrong pack. Our two fountains take different cartridges. Check which fountain you own before adding to cart.
• Rinsing and reusing an old cartridge. The carbon layer saturates; rinsing clears the surface but not the capacity.
• Running the pump without a filter. Debris reaches the impeller and shortens the motor's life.
• Waiting for visible dirt. A filter is spent long before it looks dirty — go by the calendar, not the colour.

Tip: rinse each new cartridge under cool water before placing it in the fountain.
