Breathe easy while the Uvonair OEUVA100 3000 Standard ozone generator attacks and neutralizes odors at the source. The Uvonair 3000 eliminates odors caused by molds, mildew, and tobacco smoke. The Uvonair 3000 generates one of the most powerful oxydizers available, ozone. It doesn't mask odors like an air freshener, it kills odors, then converts them to CO2 and oxygen. This ozone generator works silently with the same technology available in units costing hundreds of dollars more. The Uvonair is ideal for workplaces, offices, and homes that can benefit from purer, cleaner air.
