Carbon Replacement Filters for Cat and Dog Fountain, Premium Pet Water Fountain Dispenser Filters (10 Packs for Pure White)

These are great filters. Each filter has carbon as well sponges inside the filter and even have sponge filters for the pump. Very economical, easy to use, perfect size, and they perform well.

Good quality

Works very well, that is why I bought 2 more boxes...

Costly, but it’s all good as my cats deserve filtered water :) Product was as described and arrived in good condition.

Fits my cat's fountain well but they seem to cause algae buildup pretty quick. They don't even last a month before I have to change them.

I searched for another brand of filter that came with my fountain but they were constantly out of stock and finally found these. They work just fine also. I like the multi-pack option. only down side is the smaller sponge has seemed to unlodge itself easier and it has been floating when i change out the water. Odd. But overall i'm very pleased and when time comes i will more than likely purchase again.

They are easy to use and work well. I go a little longer than it says as we use filtered water for it!

Yoo can wash them in a tiny bit of bleach and water… soak, flip and rinse really well! They last so much longer!
