Air Filter

Fits right in box.

Not sure where this goes in the unit. There needs to be more visible instructions if u pair this with the equipment for purchase

These filters work great! Thanks!

Works perfect! No odor at all!!!

Though I was expecting a round one but can be used.

Fits the slot in the pan well and works great!

One of the filters was open and the contents were all over the inside of the shipping package. It appears that whatever seals the filters contents didn't! The filter itself was not damaged. Haven't opened the other others. One out of five ain't bad so far! Cheers

I ordered a jumbo cat litter box. The clear plastic swinging door was defective in that it was wider than the opening. When I pushed the clear plastic door, because it was too wide, it jammed to the sides of cut-out space and would not swing at all. I had to really push it hard to unstick it, and my 8-pound cat would not have had a chance of being able to enter the box with her own strength. I am a 68-year old woman who is not handy and I do not own any scissors that would be sharp enough to trim the door, nor would I know how to trim it properly (and I shouldn't HAVE to trim a door on a brand new litter box). I'm in quarantine due to the pandemic, and it wasn't worth my time or risking my life to go to to the Post Office to ship the litter box back to PetMate. So I removed the door and the litterbox is otherwise fine -- it is clean, new, room for lots of litter, and it looks fine, but there is minimal odor control as a result of the big open door space (mitigated by charcoal filters). I didn't ask for a refund because I didn't return it. I'm just stuck with it. However, the litter box works functions in every way except for having no door cover. The cat used it immediately with no adjustment issues from her previous box (which had just gotten too old). It's roomy for her, which I think she likes.
