Abstract
Engineering controls play an important role in reducing the spread of severe acute respiratory coronavirus virus 2 (SARS-CoV-2).1 Established technologies such as air filtration, and novel approaches such as ultraviolet (UV)-C light or plasma air ionization, have the potential to support the fight against the coronavirus disease 2019 (COVID-19) 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.
摘要
工程控制在降低严重急性呼吸综合征冠状病毒 2（SARS-CoV-2）传播方面发挥着重要作用。1 诸如空气过滤等成熟技术，以及诸如紫外线（UV）-C 光或等离子体空气电离等新型方法，具有支持抗击 2019 年冠状病毒病（COVID-19）大流行的潜力。2 我们使用 SARS-CoV-2 作为测试生物，在受控环境中测试了结合紫外线（UV）-C 光和高效微粒空气（HEPA）过滤的空气净化系统（APS）的功效。APS 成功地使用紫外线（UV）-C 光单独以及与 HEPA 空气过滤结合从空气中去除了病毒。
