High-Quality Materials: The replacement fountain filter is made of high-quality materials (cotton layer, activated carbon, and ion-exchange resin). The resin adsorbs hair and large debris from the water, softens the water, and reduces the possibility of stones. The sponge prevents debris from clogging and damaging the pump, thus extending its lifespan. The activated carbon eliminates odors from the water, so it always tastes fresh and clean. Compatibility: The cat fountain filter has an outer ring diameter of 145mm and a round hole diameter of 42mm, compatible with 3L Flower Cat Drinking Water Fountains. Note: Please measure your fountain's size before purchasing! Regular Replacement: The drinking fountain filter ensures clean and fresh water for your pet. To guarantee clean water, the filter should be replaced regularly. Recommended replacement schedule: Replace your cat fountain filter every 1-2 weeks in summer and every 2-4 weeks in winter to ensure clean drinking water. (If multiple pets use the fountain, the replacement frequency should be higher.) Simple and convenient to use: The cat water fountain filter is simple and convenient to use; just soak the filter in water for 5 minutes and rinse it thoroughly under running water before use.
