The global spread of Corona Virus Disease 2019 (COVID-19) makes face masks become common protective equipment for daily life. This paper introduces the protection mechanism of disposable medical face masks, and investigates the changes of microstructure and filtration efficiency of disposable medical face masks after use and disinfection. It is helpful to get more understanding about protective effect of face masks.
