Petmate Fresh Flow 替換活性碳濾芯

My dog actually drinks more water now that I've swapped in these charcoal filters—the bowl stays noticeably fresher between cleanings. They drop right in without any fuss, and one filter seems to last a good while before the water starts tasting stale again.

I keep a spare pack in the cupboard so I never run out—each filter drops right into the bowl and the charcoal does its job, my cat’s water stays fresh for days without that stale film.

My dog is a messy drinker, and these charcoal inserts have genuinely stopped that stale smell from building up between cleanings. Water stays noticeably fresher for the full few weeks, which is exactly what I needed.
