LightAir tests air purification technology against coronavirus STOCKHOLM, Dec. 15, 2020 /PRNewswire/ -- LightAir (LAIR, NGM) is initiating tests on coronavirus with a leading European virus research institute. The tests will show how well the Swedish company's IonFlow technology also prevents contact and airborne transmission of COVID19. A scientific study from Karolinska Institutet has previously shown that the technology inactivates influenza viruses immediately and continuously, and prevents airborne transmission. In the coming months, specific tests will be carried out to show how well IonFlow also neutralizes coronaviruses such as SARS-CoV-2, which causes the disease COVID19, and SARS-CoV-1, which causes the disease SARS.
