Aspen Pet Cool Flow Reservfilter

My cat used to turn her nose up at the fountain after a few days, but these charcoal filters keep the water tasting fresh enough that she drinks way more now. They snap in easily and I only have to swap one every couple of weeks.

Swapped in a fresh charcoal filter and within a day the water looked clear again instead of that cloudy film my cat kept sniffing at. It's a small thing, but she's drinking way more now, which was the whole point.

My old filter started making the water taste funny after a few weeks, but these swapped right in and the odor is gone completely. They fit the fountain perfectly and the charcoal does its job without any fuss.
