Drinkwell Replacement Filter

The Drinkwell replacement filters keep water clean & fresh and are designed to fit any Drinkwell. 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.
