Howdy yall, I have a question about cat fountains filters. I keep seeing a bunch of fountains for the cats to drink from and they all have filters that need to be replaced every 2 weeks or so. I was wondering if there was one that didnt need a filter replacement so often because my partner and I are also trying to save money and the filters will run up on cost long term.

Any ideas or recommendations are welcomed.

Thank you all for your time!!
