100% brand new and high quality The water dispenser filter is made of high-quality activated carbon and pure cotton material, which is durable and reusable. The water dispenser filter filters hair and residues, removes odors, softens the water, and is easy to disassemble and clean. It is recommended to replace it every two months to keep the water fresh and clean. It depends on the number of pets using the fountain. Allowing more pets to use the fountain will increase the saliva and debris in the water, so the filter needs to be replaced more frequently. In order to prevent the carbon chips from falling off, please rinse the filter thoroughly with running water before putting it in the filter.
