Don't let your lungs be the ONLY air purifier in your home! This industrial grade ozone generator/air purifier does not merely mask mal odors like some air purifiers, it DESTROYS odors! Utilizing activated oxygen (O3) technology, the Clevr air purifier/ozone generator oxidizes and destroys airborne contaminants such as bacteria, viruses, and odors. The oxidation process breaks down the molecular structure of bacteria, viruses, and bad odors, thereby neutralizing them. What is left is a "fresh, clean spring rain smell" similar to the clean air smell after a rain storm (nature's ozone generator).
