Aspen Pet Cool Flow 替換濾網

The charcoal in these filters actually does its job—my fountain water stays clear for the full two weeks between changes, and there's zero smell even with my two cats drinking from it daily.

My old filter was getting cloudy after two weeks, but these have kept the water crystal clear for over a month now. The charcoal really does pull the musty odor out, and my cat is drinking way more than she used to.

My picky cat refuses to drink from anything but her fountain, so these charcoal filters have been a lifesaver. The water stays noticeably fresher and odor-free between changes, and installing a new one takes me less than a minute.
