It has a filter only for pump protection and not for water. It is made only of plastic and is difficult to clean (especially the neck of the faucet). The pump is quiet, but the noise made by the water when it falls from the faucet and hits the water collected in the base is extremely loud, like having a faucet constantly open in the house. The only good thing is that water is collected in the base and your pet can drink water from both the faucet and the base. My cat didn't drink water because she was afraid of the noise, but she is a cat that generally observes faucets but doesn't drink water from them.

Perfect little fountain, my mother's cats loved it. It has a continuous water flow and is extremely quiet compared to other similar ones. Finally, it is very well-made and sturdy, and doesn't seem to have any issues in the near future like other cheaper fountains.
