Drinkwell Avalon and Pagoda Charcoal Filters - Replacement (4 Pack)

This Drinkwell Avalon and Pagoda fountain charcoal filter should be replaced, on the average, every 2 to 4 weeks.
These filters provide a secondary method of trapping any hair or debris in the water, and help keep the water tasting fresh and clean for your pet(s).
Each of these filters consist of a double density polyester pad with a charcoal core, which removes odors or any bad tastes in the water, making it more appealing to drink.
