Replacement filters for PetKit Eversweet fountains . Special three-stage filtration ensures your cats have longer access to clean and fresh water. In the first stage, a special mesh filter effectively cleans the water from hair and other impurities. Then, an activated carbon filter removes unpleasant odors and enriches the water with aroma. In the last stage, an ion-exchange resin reduces the level of heavy metals in the water. Replacing filters is no problem for you. To ensure the purity of the water and maintain the efficiency of the device, do not forget to change the filters in the drinking fountain often.
