In use, protective masks that can filter particles in the air and block droplets, blood, body fluids and secretions are also class II medical device products, which must comply with the mandatory standard gb19083-2010.

The first edition of gb19083 was formulated urgently during the outbreak of SARS in 2003, and the old version was revised in 2010. Gb19083 has clear requirements on the filtration efficiency and tightness of masks, which is similar to gb2626-2006; medical protective masks are also surgical masks, so it is not allowed to set exhalation valve to prevent the droplets generated by the wearer from polluting the surgical wound through the expiratory valve;
