Petmate Fresh Flow II uhlíkový a nečistotový filtr

The charcoal really pulls the crud out of the water—I can see a difference in the bowl after just two days. Swapping in a fresh filter takes about ten seconds, so staying on top of it is no hassle at all.

The charcoal actually does what it says—my cat’s water bowl hasn’t had that slimy film on top in over a week. Two filters in the pack means I’ve got a spare ready for when this one gives out, which is handy.

My dog’s water bowl stays noticeably clearer between cleanings since I swapped in these charcoal filters. They fit the dispenser perfectly and are easy to snap in, and two in a pack means I’ve got a backup ready when the first one’s done its job.
