無線幫浦用泡棉濾芯

I swapped out my old filter for this foam one and the water is definitely staying clearer longer. It's easy to rinse and seems to trap the little bits of food and hair my dog tracks in.

My cat’s water bowl stays noticeably clearer since I swapped in this foam filter — the fine mesh catches tiny bits of debris I hadn’t noticed before. It fits snugly into the pump without any fuss, and the durable foam holds up well after a week of use.

Didn't expect a little foam ring to make this much difference, but the water stays clear for days now instead of getting that cloudy look. It fits the pump snugly and rinsing it out takes two seconds.
