Petmate Fresh Flow -varaaktiivihiilisuodatin

I’ve been using these replacements for two months now, and my cat’s water bowl stays noticeably fresher between cleanings—the charcoal really pulls the stale tap-water smell out. The filters drop right into the reservoir with no fuss, and the water tastes clean enough that I actually refill more oft

My last filter lasted over a month and our water bowl still smells completely neutral every time I refill it. The charcoal really does pull out that stale, doggy taste that plastic bowls usually pick up.

The charcoal does exactly what it should—tap water smells neutral after a few days, and my cat stopped turning her nose up at the bowl. Filters drop in without fuss and last a good month before I notice any difference.
