Sure, being out in the sun can kill novel coronavirus on frequently touched surfaces or objects, like a smartphone, but what about when you’re inside? Introducing Time to Toast. Simply place you smartphone in the slot, press the handle down, and you have a clean device in about 10-minutes. Yes, the UV light will kill all viruses on the surfaces of your device.
Researchers at Columbia’s Center for Radiological Research are currently experimenting with far-UVC, or rays whose wavelength of 222 nanometers makes them safe for humans but still lethal to viruses. At those frequencies, the rays will not be able to penetrate the surface of the skin nor of the eye. This means they could potentially be used in closed and crowded spaces where contamination risks run high, with future promise for use during the current pandemic.
