SteriZAP® UV-C HVAC Sterilizer metro The purifier uses HEPA filtersUV C light is electromagnetic radiation with wavelengths shorter than visible light. UV C can be separated into various wavelength ranges, with the short wavelength UV C considered to be germicidal. Furthermore, and at the specific wavelength range of 260 to 270 nm, UV C is found to be mutagenic to bacteria, viruses and other microorganisms.
