Great for litter boxes
We have a &#34;booda dome&#34; litter box with a charcoal filter and use baking soda in the box and our house still smelled like cat litter when you first walk in. I try to avoid using chemical or artificial smells to cover it up. This device cleared all odor within 48 hours!  Runs a little loud but it is not unpleasant white noise. Very pleased, bought one for my parents' cat too.
