UV Lights installed in your HVAC may help keep the evaporator coil clean but are ineffective at cleaning the fast moving air that passes by them. The HiTech Air Reactor is available as a customized in-duct unit that installs in-line with your HVAC system. As opposed to UV Lights alone, the Air Reactor produces stabilized Super Hydroxyl Molecules that seek out and an destroy contaminates not only within the HVAC system but throughout the entire indoor environment. Whether you choose the custom in-duct version or use one of the portable model Air Reactors you get the same benefits from the Super Hydroxyl Molecules – clean air and surfaces throughout your indoor environment.
