PetSafe Drinkwell Porcelain and Stoneware Pet Fountain Charcoal Filters are made from organic coconut shells. These filters are designed around the filters used in aquatic fish tanks. The charcoal does not purify the water, but does aid in removing bad tastes and smells, as well as help keeping large particles and other debris from re-circulating back into the water.
