Home / Science of UV-C Technology

Light is comprised of different wavelengths, each with their own unique properties. The germicidal properties of ultraviolet (UV) light, part of the non-visible spectrum, can be harnessed to effectively sanitize the air, water and surfaces. At the appropriate wavelength and fluence (dose), exposure to ultraviolet light modifies or destroys the genetic material (DNA and RNA) in viruses, bacteria and mold, preventing replication.

Surface sanitizing products employ various combinations of UV light and filtration to inactivate pathogens, including Far UV-C (200-230nm), UV-C (231-280nm) and UV-A (365nm).



The effectiveness of UV on inactivating or destroying microbes depends on the microorganism’s structure, size and resilience, in addition to the UV exposure parameters including duration of exposure, wavelength and intensity (see SCIENTIFIC SUPPORT).

UV-C (231-280nm) must be shielded from humans as it poses a carcinogenic safety risk. Continuous low doses of Far UV-C (200-230nm) have been studied and no human effects reported (see SCIENTIFIC SUPPORT).
