Drinkwell Premium Replacement Filter Cartridges (3-Pack)-Premium 6-Chamber

The New 6-Chamber Drinkwell Premium Replacement Filters will fit all models of Drinkwell products. They keep the water clean and fresh to encourage your pet to drink more water. Construction consists of two pads that filter the water, as well as granulated charcoal. The first pad is a duo density polyester pad, which filters out large particles such as food and hair. The second pad contains impregnated carbon which filters out bad tastes and odors, making the water more appealing to drink to your pet. Finally, granulated charcoal is added between the pads for extending the filtration. The new 6-chamber frame distributes this charcoal more evenly, giving the water a more thorough cleansing. Filters must be changed every 2-4 weeks (or every other cleaning of the whole fountain), so a 3-pack should last 1.5 to 3 months.
