UV Light for Sanitization

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.

Healthe air and 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).
