Ozone machine recommendations needed

[Andy Webb]

We're looking at buying an ozone machine to help with odors after tenants vacate.  Our houses are generally 1200-2000 sf.  What brand and model would you recommend?  

Thanks for any input.

We have only used one kind, and have been pleased with this model.  We ordered it online, and place it in a room, turn the dial for an hour, close the door, exit the room and then wait for two hours.  It will kill mold, as well as any critters that are in that space.  This one does 1000 square feet.  It uses UV as well as ozone.  There are some which serve a larger square footage, but we wanted a unit that would have the additional ability to treat mold with UV.
