6-Piece Litter Box Filters for Hooded Cat Litter Box – Activated Charcoal Filters Eliminate up to 99% of Litter Box Odors – 6 Inch x 6.5 Inch Trimmable Pads

2 cats using one box. Contains and eliminated the odor immediately. Glad I bought extras.

I started looking for these when I got a covered litter box. The box came with a filter just a little thicker than these and fitted for the shape of the box but I could not find refills for those anywhere. I held off on writing a review until I actually changed my filter for one of these. They were easy to cut to fit the opening in the box. And after installation there have been no odors escaping from the box. Since the space was meant for a thicker filter I folded it before cutting so it is actually double. It works.

These filters arrived on time and fit perfectly for my cat's litter box. They don't really have a scent, though. It does help with odor in the room not to be as bad, however. I think it gets the job done just fine. I would buy them again.

Easy of use and it works well

The material is not thick enough to stay on the liitter box properly and the cats remove it all the time.
