Review on 🐱 Resinta 6-Pack Activated Carbon Filters for Cat Litter Boxes - Charcoal Filter Pans by Shantel Griffin

These filters are almost twice as thick as the ones I replaced. I had to use needle nose pliers to get them into the holders. I broke one of the slats on the tray when installing it. I would return them but I have already trimmed 2 of these to fit the width of the filter holes. In addition, one of the filters is not even in the depth of the filter layer. It has about 6 channels that looks like something hot and heavy is being pushed into the filter causing it to shrink. I just installed 4 of these in 2 bowls and they helped reduce the smell a bit. I had to remove a significant amount of charcoal dust after installation so I'm hoping this means they control odors adequately.
