Set of 8 Pet Water Fountain Filters with 8 Filter Sponges, Compatible Replacement Filters for Dogs and Cats

The package contains 8 replacement filters and 8 replacement sponges for the water pump. The cat filter is compatible with the avocado-shaped drinking fountain. Please check the size before purchasing. The cat fountain filter is made of activated carbon, filter floss, and cationic resin. These materials filter out hair and heavy metals and improve the taste of the water, so pets can drink clean, fresh water all day long. The drinking fountain filters provide clean drinking water for cats and dogs, help increase water consumption, and reduce the risk of urinary tract infections. The pet filter is easy to install, remove, and replace. To prevent dust from settling on the filter surface in the drinking water, please soak the filter for 5 minutes before use. To maintain the drinking fountain's filtration efficiency, we recommend replacing the filter every 2-4 weeks.
