If you live in the Louisville, Kentucky area, take one of our A7K Air Ozone Generators home with you to experience the intense power of ozone. The A7K is a 7000 mg/hour machine that is capable of eradicating mold or intense odors. Simply plug in the A7K and set on the desired treatment, exit the room, and return after the ozone has dissipated for a fresh-smelling area! For some strong odors, it may be necessary to repeat the treatment.
