New Improved Larger Unit and Design - Over 4,500 mg of ozone production and a new larger fan produces more ozone and sterilizes more square footage for the same price. Compare to other generic square ozone generators on the market and our larger fan, better timer unit, and proprietary ozone plates distribute more ozone more efficiently at a lower cost. Get more odor elimination for less money! Now that's value! 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 Enerzen 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). Over 4500 mg/hr of ozone produced kills germs, deodorizes, and freshens the air. Power: 55W, 110V AC. Timer Function. Size: 8.75"(H) x 10"(W) x 7.75"(D). Satisfaction guaranteed: 30 days unconditional replacement or refund if you are not satisfied. Factory Warranty: 1 year. CE certified and approved (HBSC2013012307)!
