Indoor air pollutants and airborne contamination removal have been challenging in healthcare facilities. The airborne transmission control and HVAC system may collapse in hospitals due to the highly infectious respiratory disease-associated patient surge, like COVID-19. Common air filtration systems and HVAC systems enhance the patients' comfort and support indoor hygiene, hitherto insufficient to control highly infectious airborne pathogens and hospital-borne pollutants such as radon, PM, patient droplets, VOC, high CO, and anesthetic gases. This review summarized important air cleaning interventions to enhance HVAC efficiency and indoor safety. We discussed efficient air cleaning and ventilation strategies including air filtration, air ionization, passive removal materials (PRM), and UVGI to minimize cross-contamination in hospital wards.

在医疗机构中，去除室内空气污染物和空气传播污染物一直具有挑战性。由于 COVID-19 等与呼吸道疾病高度相关的传染性患者激增，医院的空气传播控制和暖通空调系统可能会崩溃。普通的空气过滤系统和暖通空调系统提高了患者的舒适度并有助于保持室内卫生，但迄今为止，在控制高传染性空气传播病原体和医院传播污染物（如氡、颗粒物、患者飞沫、挥发性有机化合物、高浓度一氧化碳和麻醉气体）方面仍显不足。本综述总结了重要的空气清洁干预措施，以提高暖通空调效率和室内安全性。我们讨论了高效的空气清洁和通风策略，包括空气过滤、空气电离、被动去除材料（PRM）和紫外线光解，以尽量减少医院病房中的交叉污染。
