Cat H2O & Dog H2O Replacement Filter Pads combine a sponge layer that traps hair and debris with activated carbon that absorbs impurities, odours and unpleasant tastes from tap water, sold as a 3-pack.

Two layers, two distinct jobs

The sponge layer physically traps loose hair and debris before it can circulate through the pump, while the activated carbon works chemically, absorbing impurities, odours and unpleasant tastes that can make tap water less appealing to a pet — two genuinely different filtration mechanisms working together.

Each filter lasts about one month, and the 3-pack gives roughly a quarter's worth of replacements before needing to reorder.

• ✓Sponge + activated carbon. Two distinct filtration mechanisms.
• ✓Each filter lasts about one month.

Care & use

Replace the filter in your fountain approximately every month, or sooner if water flow slows or odour returns.
