Review on Ivation 5-in-1 Air Purifier & Ozone Generator with UV Lights, Photo-Catalytic, and Carbon Filters, Eliminates Odors from Pets, Smoke, Food & More, Ideal for Spaces up to 3,500 Sq/Ft by Becky Duncan

Bought to get rid of the smoke smell (I bought a house where a heavy smoker lived). It works, it's simple and clear. We had to do a room twice (once on a low level, the other on a high level) due to the concentration of the smell. No smell after the second round. Very glad we got this. WARNING: Do not leave live animals of any kind, including annoying relatives, inside while this is in progress and for a while after you've opened doors and windows, if it's doing its thing (I don't know about plants, but I would take them outside bring be sure). My computer, TV, etc. were fine during the run, but the animals may not be feeling too well.
