Review on Pure Air - 2 Units: Negative Ion Air Purifier Plug-in | Mini Portable Generator for Home | Eliminates Smells, Pollutants, Smoke & More | Ideal for Bedrooms, Toilets, Living Rooms, Bathrooms, Closets, and Pet Rooms by Dedra Block

Not much to say about this. We switched cat litter brands a few weeks ago and the new brand (arm and hammer) seems to leave a more musty smell in the room so I decided to give it a try. Musty smells are significantly reduced in our laundry room (approx. 6 by 10 feet) with two plugged-in outlets. Allergies are making my nose a bit and I can't say much more about the smell.
