      Information
        Medical protective masks have both the protective performance of surgical masks and particulate protective masks. In use, protective masks that can filter particulates in the air and block droplets, blood, body fluids and secretions are also classified as Class II medical device products. Must comply with the national mandatory standard GB19083-2010.
        The first version of GB19083 was urgently formulated during the SARS outbreak in 2003, and the old version of the standard was revised in 2010. GB19083 has clear requirements for the filtration efficiency and tightness of the mask, which is similar to GB2626-2006 at this point; medical protective masks are also surgical masks, so it is not allowed to set an exhalation valve to avoid droplets generated by the wearer. Exhalation valve discharges the contaminated surgical wound;
        Many medical protective masks use the blue-green shown on the outside, which is just a habit in the medical industry, and the material on the outer surface of the mask has a barrier effect on body fluid splashing. In this regard, non-medical particulate protective masks are usually not considered .
