Cat Water Fountain Filters, 12 Carbon Filters + 12 Foam Sponge Filters

24 Pack Cat Water Fountain Filters: Includes 12 activated carbon filters and 12 black foam sponge pre-filters for regular pet fountain replacement. Keep a complete filter supply ready for everyday fountain care without purchasing the two filter types separately. Helps Filter Hair, Debris & Odours: Each cat fountain filter combines fibre cotton with activated carbon to help capture hair, sediment and debris while reducing unwanted odours, helping maintain fresher flowing drinking water for cats and pets. Foam Sponge Helps Protect the Pump: The black sponge filter fits around the pet fountain pump to help catch hair and larger debris before they reach the pump. The carbon filter and sponge work together as part of the fountain filtration routine. For Many Stainless Steel Pet Fountains: Replacement filters designed for many 2L, 3L, 3.2L and 4L stainless steel cat water fountain styles. Compatibility depends on the fountain design, so compare the filter shape, dimensions and installation position shown in our images before ordering. Soak & Rinse Before Use: Soak the activated carbon filter in clean water for 5 minutes, then rinse thoroughly before installation. Clean your fountain regularly and replace the filters according to fountain use, water condition and the number of pets.
