The outbreak of COVID-19 disease, the cause of severe acute respiratory syndrome, is considered a worldwide public health concern. Although studies indicated that the virus could spread through respiratory particles or droplets in close contact, current research have revealed that the virus stays viable in aerosols for several hours. Numerous investigations have highlighted the protective role of air purifiers in the management of COVID-19 transmission, however, there are still some doubts regarding the efficiency and safety of these technologies. According to those observations, using a proper ventilation system can extensively decrease the spread of COVID-19. However, most of those strategies are currently in the experimental stages. This review aimed at summarising the safety and effectiveness of the recent approaches in this field including using nanofibres that prevent the spread of airborne viruses like SARS-CoV-2. Here, the efficacy of controlling COVID-19 by means of combining multiple strategies is comprehensively discussed.

纳米技术在空气净化器中的应用作为预防冠状病毒的可行方法。

COVID-19 疾病的爆发是严重急性呼吸系统综合症的原因，被认为是全球公共卫生问题。尽管研究表明该病毒可以通过密切接触的呼吸道颗粒或飞沫传播，但目前的研究表明该病毒在气溶胶中可存活数小时。大量调查强调了空气净化器在管理 COVID-19 传播中的保护作用，但这些技术的效率和安全性仍存在一些疑问。根据这些观察，使用适当的通风系统可以大大减少 COVID-19 的传播。然而，大多数这些策略目前还处于实验阶段。本综述旨在总结该领域最新方法的安全性和有效性，包括使用纳米纤维来防止 SARS-CoV-2 等空气传播病毒的传播。在此，综合讨论多种策略相结合控制COVID-19的功效。
