Looking for a metal, antimicrobial cat fountain

I want to replace our current plastic, Wondercreature fountains as the filters are now annoying to find.

Ideally, I want an antimicrobial metal and a UV light inside with an easily replaceable filter but stainless steel will be fine if I can't. I'm slightly concerned that copper will corrode over time but I'm not sure how much of a problem that will be.

Also, if it can go through a place that is not Amazon that would be great.
