Good product, Great Price!

Easy to use and my pets water is cleaner

They’re very easy to install. There actually is no noise with the filters. The fountain is just the sound of running water. My cats love their fountain!

This is a great mostly universal size filter for animal water dishes. I have bought this more than once.

One of them was missed.
