For use with the PetSafe Drinkwell Mini drinking fountain, Original drinking fountain, Platinum drinking fountain or Big Dog drinking fountain.

The DRINKWELL Premium Replacement Activated Carbon Filter from PetSafe keeps the water in your drinking fountain clean and fresh.

Each filter has two filter pads: one layer of polyester to trap hair and other debris and a second carbon impregnated pad to eliminate bad odours and thus a bad taste, and each replacement filter is divided into 6 chambers to ensure an even distribution of activated carbon in the filter. This enables consistent filtering of the water to keep it fresh and clean. Replace the filter every 2 to 4 weeks or as soon as signs of saturation with foreign matter (impurities, food residues, hair, etc.) become recognisable.

The filter should be replaced every 2 - 4 weeks.
