Features: The pet water dispenser filter uses coconut shell activated carbon, which is healthier than regular activated carbon. The cotton filters out hair, sediment and debris, making the water clean. Activated carbon adsorbs impurities and odors, making the water fresh and clean. Resin softens the water and reduces the chance of lithiasis. The pet fountain replacement cartridge allows multiple filtration and purification to soften water and prevent urinary problems, such as pet urinary stones. Compatible with most 1.6 liter / 2.4 liter dog and cat water fountains. Please clean the new cat water filter replacement thoroughly under running water to remove loose dirt before use.
