Removal of SARS-CoV-2 Bioaerosols using Ultraviolet Air Filtration.

Engineering controls play an important role in reducing the spread of SARS-CoV-2 (1). Established technologies such as air filtration and novel approaches such as UV-C light or plasma air ionization carry the potential to support the fight against the pandemic (2). We tested the efficacy of an air purification system (APS) combining UV-C light and High Efficiency Particulate Air (HEPA) filtration in a controlled environment using SARS-CoV-2 as test organism. The APS successfully removed the virus from the air using UV-C light by itself and in combination with HEPA air filtration.
