I really don’t know how this really works? I hear no sound . I guess I’ll have to see if any change threw a month . I have allergies to my dogs and cat. That’s why I got the purifier.

I like them because they quiet and I don't smell dog but she's not about to me. Anyway, I have to put two in my room for the smoke

I have 3 cats and I just started using this but I do believe it is hoping to eliminate litter box odors
