For many contractors and service techs, ultraviolet (UV) lights have become a much more common system accessory. They have certainly piqued the interest of residential and commercial consumers.
Most of these people do some preliminary searching online when they are looking into indoor air quality (IAQ) solutions. When they find information on UV lights, they will come across what may be unfamiliar scientific terminology - nanometers, UVV, UVC, and the light spectrum. They may find some basic information on UVC, but there isn't much out there about UVV, and UVV is one of the best weapons in the arsenal against poor IAQ.
