The Drinwell Replacement Filters keep water clean & fresh and are designed to fit any Drinkwell Fountain. Each filter is constructed of two filtration pads; first a duo density polyester pad is designed to catch large particles such as hair and other debris, second a carbon impregnated pad quickly removes bad tastes and odors that make water unappealing to drink. In between the pads we have added granulated charcoal for extended filtration. Filters should be changed every 6 weeks for cats and 4 weeks for dogs

Package of 3 Filters

Upgrade to preimium Filters:

The Drinkwell Premium Filters feature 6 compartments which evenly distributes the charcoal for a longer lasting, deeper water filtration. More charcoal is added to each compartment to maximize water filtration. This filter will work with any Drinkwell Fountain.
