OVW pureAir OverWATCH

Commercial Active Air Purification For Large Spaces

​Support occupant health and well-being with proven air purification solutions from US LED. Our active air purification products recreate the same processes in nature, safely destroying harmful viruses, bacteria, mold, odors, and other pathogens. Unlike passive filters that affect only air that passes through them, this air purification system projects purifying solutions to the sources of pollution, continuously reducing odors and airborne particles.

OverWATCH provides continuous purification for all types of large commercial spaces, especially for applications where water-resistance is required like food processing or food warehouses. Even the portable roll-a-round model offers versatility in remediation for large spaces in healthcare facilities, daycare facilities, extended care, and more! Utilizing a proprietary form of photocatalytic oxidation called Active Radiant Catalysis (ARC®), the OverWATCH solution uses energy to activate a catalyst that turns moisture into effective advanced oxidation products (AOPs). These AOPs continuously sanitize the air and surfaces, actively destroying microbes and rendering contaminants harmless.
