Ulisem 8-piece filter set, compatible with 3L pet water dispensers, cat water dispenser filter with activated carbon and ion exchange resin

Perfectly compatible: Our cat water fountain filter is compatible with most 3-liter round pet water fountains on the market (filter diameter: 14.6 cm). Please check the size carefully before purchasing. 【Triple Filtration Protection】 This cat water fountain filter consists of a layer of cotton, activated carbon, and ion-exchange resin, which can filter out hair, debris, and impurities, effectively eliminating odors in your cat's water and ensuring healthy drinking water for your pet. Replace the filter regularly: We recommend replacing the filter element regularly to keep your cat's water clean. Replace your cat's water fountain filter every 1 to 2 weeks in summer and every 2 to 4 weeks in winter, or more frequently if multiple pets use the fountain. [Note] Soak the filter in water for 3 minutes before use and rinse thoroughly under running water to keep the product clean and the water fresh.
