The QT Hurricane Ozone Generator gives you the same power you would expect in the Queenaire Cyclone Ozone Generator with the added convenience of a 7 day 6 cycle programmable timer. It produces up to 1,250 mg/hr of ozone to remove your worst odors. This is a great choice for garbage areas | dank basements | crawl spaces | sewage odors | locker rooms - or any area that needs daily deodorization. All Queenaire models have a 5 year warranty and a 15 – 20 year life expectancy.
