Want to kill Covid? 30 sec under 285-nm UV-LEDs will do it

December 15, 2020 By Lee Teschler 1 Comment

UV LED

Researchers from Tel Aviv University found that UV light at a wavelength of 285 nm was almost as efficient in disinfecting the Covid virus as a wavelength of 265 nm, requiring less than half a minute to destroy more than 99.9% of the coronaviruses. They say this result is significant because the cost of 285-nm […]
