Works for cat litter odor control
Definite cat litter odor control with one unit in a 150 sq ft room in a multi (and I mean multi) cat household. Several different air filters have been tried in the past and eventually abandoned due to messy maintenance, costly replacement filters, and dubious final air quality. But something had to be tried with new additions to an already multi-cat home. It's not instantaneous, but removed odors within a few hours and continues to knock out litter odors. It is a bit noisy considering its size - I wouldn't want it in the bedroom - or it would get 5 stars.
Rating: 4 stars
