Filters for Drinkwell Fountain's

These replacement filters are for the Drinkwell Pet Fountain Platinum item #7650P, Mini Drinkwell Pet Fountain item #7652 and the Drinkwell Multi-Level Pet Fountain item #7656 (sold separately).
They're pictured so you can see the front and back side. These filters feature (1) duo density polyester pad; (2) carbon impregnated pad; and (3) granulated carbon. This advanced triple layer ensures the cleanest possible water output. (Your filter will need changing when it becomes clogged with debris and water back flows excessively. You can rinse cartridges in the sink to clear out debris and extend the life. Cartridges last for weeks before changing is necessary).
Set of 3. Replace every 2-4 weeks
