VegasDoggy Water Fountain Filters Pets Cats Good Senses Replacement Automatic Flower Dispenser Activated Carbon Filter for Mospro Design Pack of 4 PCS

These are okay. I got these to replace my Dogit and Catit filters, but they are not quite big enough and I am not sure they are filtering correctly. I will be buying the branded items because I know they work.

I've had the water fountain running for over a year and my animals all used it daily. However, once I started using these filters, none of them will touch the water. The only difference is the yellow Ion Exchange Resin present in these (instead of all activated carbon), so I have to assume that is the culprit. I do not recommend these or any other filters with that yellow resin present.
