Drinkwell® Replacement Charcoal Filters keep your pet's water tasting clean and fresh. Each filter features a duo-density polyester pad that catches hair and debris, while the charcoal removes bad tastes and odors from the water making it more appealing to drink. Filters help extend the life of your fountain and pump and should be replaced every 2 to 4 weeks.
Each filter is constructed with two filtration pads; first a duo density polyester pad that's designed to catch large particles such as hair and other debris. The second carbon impregnated pad removes bad tastes and odors, making the water fresher and more appealing to drink.
In between the pads we have added granulated charcoal for extended filtration.
Works with the following fountains:
