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.

Researchers said that the technology can help to deactivate the virus in public areas such as hospital and lower the risk of cluster spreading. In the post pandemic era when people are returning to work and other social activities, it is important not only to maintain safety social distance but also integrate essential technology to reduce the possibility of group infection.

The deep UV LEDs are installed in Nikkiso’s air cleaning and deodorizing device which launched in January.
