UV light at most wavelengths can kill COVID–19. andriano_cz/iStock via Getty ImagesScientists have long known that ultraviolet light can kill pathogens on surfaces and in air and water.

The Excimer UV Cleaner uses UV light (Xe excitation at 172 nm) to remove these contaminants from the specimen surface. This method can also be used to hydrophilize a specimen’s surface. Image Credit: ...

The mercury lamp (254 nm) needed 20 s exposure to reach similar virucidal activity, while the excimer lamp (222 nm) had a LRV < 2 with limited anti-SARS-CoV-2 activity after 40 s of exposure.
