✅ [Set Included]:You will receive 4 carbon filters and 4 foam filters. Replacement filters size is 7.6*4.2cm and the inner diameter of the foam is 6cm.
✅ [QUALITY MATERIALS]:The surface of the cat fountain filter contains a cotton surface with activated coconut shell carbon and a sponge to protect the pump. The outer layer of high-density cotton keeps the water isolated from hair and other impurities, effectively purifies the water and provides pure water for your cat.
✅ [EASY TO USE]:The cat fountain filter is easy to use and can be easily installed with the raised side facing up and the flat side facing down. Both filters provide adequate filtration and the cat fountain filter eliminates pet odours.
✅ [Suggestion]:To prevent activated carbon dust (harmless to pets) from settling in the water, soak the filter in water for 5 minutes before use and rinse thoroughly under running water. Replace the activated carbon filter every 2-4 weeks, depending on how often you drink the water and how many pets use the fountain. Replace the sponge filter every 2 months.
✅ [WIDELY COMPATIBLE]:This cat fountain filter is compatible with most stainless steel cat water fountains. It filters out hair, particles and heavy metals and improves water quality so your pet can drink fresh, clean water from the fountain.
