ペットメイト フレッシュフロー 交換用活性炭フィルター

My cat's water bowl was getting slimy every other day, but after popping one of these charcoal filters in, the water stays noticeably fresher for almost the full month. The water even tastes cooler and less stale to me when I change it.

The charcoal does exactly what it promises—my dog’s water bowl stays odor-free for a full two weeks, even in summer heat. I just pop a new one in each month and the water tastes noticeably cleaner to me, which means she drinks more.

My cat is picky about water, but she's been drinking way more since I swapped in this charcoal filter. The water actually smells fresh now instead of stale after a couple days.
