Why Use RGF’s Photohydroionization Technology?

Germicidal UV light rays have been used for decades by the medical industry as a method for destroying micro-organisms (germs, viruses, bacteria). UV lights can be easily installed in HVAC ducts or a plenum, and they are effective on stationary surfaces within direct line of site from the UV lamp.

However, germicidal UV light is not effective in reducing airborne micro-organisms in the moving airstream, as typical UV lights do not provide enough UV energy to inactivate the airborne microbes within the available contact time. Germicidal UV lights also have little to no effect on gases, vapors or odors. Photohydroionization Advanced Oxidation, on the other hand, is very effective on gases, vapors, VOCs and odors, as well as the airborne microbes found traveling throughout the HVAC system.

The main advantage...

Guardian Air™ does not need the pollutants to travel to the air handler for UV treatment or filtration. Guardian Air™ is proactive and sends ionized aggressive advanced oxidizers into the room to destroy the pollutants at the source, in the air and on surfaces, before they can reach your family, clients or employees.
