The generator generates ozone, a form of oxygen which is synonymous with clear, fresh, invigorating air. The ozone is delivered at a controlled rate into the atmosphere where it attaches itself to airborne and surface contaminants, destroys them, then reverts to pure oxygen. By literally oxidizing impurities in the air, the ozone destroys bacteria, mildew, mold and fungi. It works quickly, with significant results appearing within the first hour of operation.
