My cat appreciates this system. The filter adds even more purification to the already great stainless steel water filter. She is 16 years old and drinks like a fish out of the water. Filtration of the water before filling the fountain up gets even better water quality for the kitty. Amazing add-on

Great replacement filters. Easy to install keeping fresh available water to you fur baby. These filters fit the bigger model so make sure you double check which model you have. Also includes the foam replacement cover.

This replacement water fountain filter is exactly what I needed for my wireless water fountain. It came with 3 sets of water filters, plus 3 sets of each of the other filters needed for this fountain. Quick shipping and easy to install.

If you really want to spoil your pets, then you need this filtration system. These are the replacement filters that come 3 in a box so it lasts for over a month. It is easy to assemble and clicks right onto the Penthouse Paws Wireless Water Fountain. I love knowing that my dogs have fresh clean filtered water!

This water fountain filter set come with 3 replaceable filters along with the 2 types of black carbon filters this water fountain takes. I love having the replacement items on hand so it’s nice that this set comes with everything you need for 3 full replacements.

We have looked everywhere for these filters and could not find them anywhere around us. We are so happy that Wayfair has little odd ball things on their website along with everything else that have. We are so pleased

I have the other filtration system. These filters are nice and looks like mini replacements for a refrigerator. Just seeing the filters makes me want the buy the more expensive fountain. I would recommend both filtration systems made by this company.
