Filter Unit RECT 5PCS

The charcoal layer in these filters makes the water taste noticeably cleaner—my picky cat is drinking way more now. They were super easy to swap out and fit perfectly.

The multi-layer filtration really does make a difference — the water stays clear way longer than with the old inserts, and my cat drinks noticeably more now. Five filters in one pack is solid value too.

Swapping these in takes about ten seconds and the multi-layer filter really does catch the stray fur that used to float in the bowl. Five packs lasts me ages, so I'm not ordering replacements every other week.
