Ozone is a molecule composed of three oxygen atoms, and it is only produced at wavelengths below 240 nanometers (nm), with peak production occurring at 185 nm. The Centers for Disease Control and Prevention (CDC), the National Institute for Occupational Safety (NIOSH), and the Department of Health and Human Services (DHHS) have all recommended using UV light to reduce tuberculosis (TB) transmission in hospitals. To this end, they have drafted a manual for effectively installing UV light, which suggests using UVGI (ultraviolet germicidal irradiation) light technology to inactivate airborne TB bacteria. A study commissioned by the United States Department of Energy found that photocatalytic oxidation, when combined with a surface coated with TiO2 (titanium dioxide), can convert more than 95% of hazardous chemicals in volatile organic compounds (VOCs) into harmless carbon dioxide and water molecules. UV lights can also significantly reduce the number of microbes in your home's ducts, coils, and airspace.
It is important to note that ozone is mainly generated within the UV or UVV range of the vacuum, between 100 and 200 nm, particularly at the UV wavelength of 185 nm. This is much lower than all Steril-Aire UVC products. When the UV light system is installed in the air conditioning system (inside the walls of the ducts), there is no direct or harmful exposure to you or your family. UV air purifiers use ultraviolet light to reduce mold and mildew, VOCs, airborne pathogens, flu, germs, bacteria, viruses, and other harmful airborne contaminants. Although UV light can be dangerous, especially when exposed to it for too long, these purifiers are designed to keep people safe from any potential harm.
