An essential part of whole-house air purification, the dual lamp OxyQuantum LED is a combination UVC and UVV system designed to dramatically reduce and control odors, airborne toxic compounds and infectious agents. The patented UVV chamber provides precise control of UVV output that can be easily adjusted by the homeowner. The high output 190 mW twin UVC lamp extends almost 16 inches into the ductwork for maximum efficiency. As with all One Hour IAQ products, the OxyQuantum LED is certified as safe and beneficial for residential use by the International Indoor Air Quality Association. For HVAC systems up to 5 tons.
