Comsmart Cat Fountain 6 Sponge Filters Replacement, Pet Dog Fountain Sponge Foam Filters for Round and Cubic Stainless Steel Top Cat Water Fountain Automatic Drinking Water Dispenser

They fit the size of the water purifier for the cats great. They last about six months and keep the water clean. The value for the money is about a medium. The functionality is a little different because it has cut outs on it, that the one that came with it didn’t have.

Work as they are supposed to

Nice price, easy to use, and shipped promptly. They are quiet

They fit as needed, nothing special about the inserts they were exactly as described.

Really does a great job at filtering.

I have a dog and two cats who share the bubbling fountain. The filter does a good job. I change it monthly

The cat waterer stays cleaner longer when using the filters.

I ordered these filters to add on to the pump in my Comsmart Cat Water Fountain (81 ounce, stainless steel, round), but they do not fit and stay on the pump. The plastic shown in this filter's listing, where the filter would be inserted at the edge of the pump, is not actually the same as shown. The filter doesn't slide in and stay there at the bottom of the fountain. The filter just floats away from the pump and is useless. I missed the return window by a day, unfortunately.

Good quality
