Save your money!  Does NOT work!
If I could give ZERO stars, I would. I saw all of the rave reviews for this, so I got it for my teenage son’s small bedroom. This has to be a joke!  It did not eliminate any typical odors one might have in a teen’s abode. I can’t imagine if I plugged it in my kitchen or had it by a litter box.  It wouln’t do anything either - & those odors have to be more pungent. Save your money!  This does NOT do what it says it does. A waste of a lot of money!
