Absorbs any light and converts it into a UVC frequency emission of 265nm
UVC level irradiates 3.5” around the mask
UVC emission level is constant for 2 hours if there is no source of light after being charged for 30 minutes, but it functions at a constant UVC level if there is any source of light shining onto the mask. This would include scenarios of being outside in the sun, or inside in a store.
Why is this important?
“Sunlight or solar UV radiation (UV) acts as the principal natural virucide in the environment. UV radiation kills viruses by chemically modifying their genetic material, DNA and RNA. The most effective wavelength for inactivation, 260 nm, falls in the UVC range, so-named to differentiate it from near-UV found in ground-level sunlight, i.e., the UVB and UVA portions of the spectrum, 290 to 320 nm and 320 to 380 nm, respectively. Nucleic acids are damaged also by UVB and UVA but with lower efficiency than by UVC radiation.”
