I really like how small this item is, but also I think if it was bigger it would work even better. It does help my room since I keep my bearded dragon in my room. His enclosure is clean ' just when he poops and I'm at work I can't clean it right away and It stinks so much When I get home from work. But this makes it from 100% stinky to 45% stinky Lol. But I think I'm gonna return this one and get a bigger one because I am really liking having better quality air.
