Joint Research by Nikkiso and University of Miyazaki Proves Effectiveness of Deep UV LED in Preventing Spread of COVID-19

Japan-based medical equipment supplier Nikkiso has collaborated with the University of Miyazaki and announced that its deep UV LED adopted apace disinfecting device can effectively prevent the spread of COVID-19.

The two parties conducted trials by exposing SARS-CoV-2 viruses contained liquid under deep UV LED radiation for 30 second and found that virus infectivity decreased by 99.9%. The experiment went on two months and the effectiveness of deep UV LED for preventing COVID-19 infection is confirmed.
