Filters as Expected
These are filters for cat water fountains. They work great as long as my kids don't pour all the cat food into the fountain. They are the same shape and size as the more expensive ones from the manufacturer.

Frequently Asked Questions
Quadruple Filtration Process:
Each pet water fountain filter consists of two layers of high-density microporous filter cotton, natural coconut shell activated carbon and ion exchange resin, which is chemical-free, safe and healthy. Healthier than other filters with only two or three filter materials. Quadruple action purification can filter hair and residue, absorb odor and soften water.
Better Purification performance:
Compared with most pet water fountain filters on the market, Smart Pet Water Fountain Filter contains more activated carbon, and the ample filling has stronger adsorption capacity than other filters, so it can achieve better purification performance.
Keep Pets Healthy:
Pet water fountain filters can filter hair and residue, absorb odor and soften water. They can improve the taste of water and keep water fresh. Help you encourage your pet to drink more water and stay healthy.
Independent Packaging is Safe and Hygienic:
It is convenient for the storage of the filter element, and it can also effectively prevent moisture and be more hygienic.
It is recommended to replace it every 2-4 weeks. Depending on the frequency of your pet's drinking and the number of pets, when using a water fountain, please replace the filter of the cat water fountain every 1 to 2 weeks in summer and every 2 to 4 weeks in winter.
These Smart Pet Water Fountain Filters are designed to fit seamlessly with a variety of popular automatic pet water fountains, including Catit Flower Fountains, etc. These filters are round and have a diameter of 5.5 in (14cm).
When installing, please place the convex side upward.
Please soak the filter element for 15-20 minutes before use. Before use, the filter should be soaked and rinsed under running water to prevent the activated carbon powder from falling into the water.
Please replace the cat fountain filter after 2 to 4 weeks of use to keep the water fresh and clean.
A small amount of carbon dust may be released during the filter's life, but this is harmless to your pet.
