Drinkwell® Premium Replacement Charcoal Filters keep your pet's water tasting clean and fresh. The premium filter segments the charcoal into 6 compartments, reducing the settling of the charcoal and enhancing overall filtration. Each filter features a duo-density polyester pad that catches hair and debris, while the charcoal removes bad tastes and odors from the water to make it more appealing to drink. Filters help extend the life of your fountain and pump and should be replaced every 2 to 4 weeks. Compatible with most Drinkwell fountains.
