Actually works, which is a bit of a surprise.
I rarely leave product reviews but this thing surprised me in its effectiveness so I’m leaving one. Most of the air filter smell reduction technology they sell, especially at that size, is useless. I’ve had innumerable air purifiers and plug-in wall unit charcoal filter that have been terrible. I bought one of these for my second bathroom that has my cat boxes in it, put it in, and left the door just open enough for the cats to get in and out and it’s probably reduced the smell inside that room by at least half if not more. I bought a second one to put right outside the door in the lead in bedroom itself and the cat litter smell creep  has basically been reduced to zero. We will see how this is working a few months down the line but in the two weeks I’ve had it I’ve been really impressed and frankly shocked at how well it’s worked.
