The biggest feature of the KN95 mask is that it can prevent droplet infection caused by the patient’s body fluid or blood splash. The size of the droplets is 1 to 5 microns in diameter. Medical protective masks are divided into domestic and imported ones. They have the protective performance of medical surgical masks and particulate protective masks. They are used exclusively in hospitals to filter particulates in the air and block droplets, blood, body fluids and secretions. The current n95 masks, in principle, can prevent 95% of non-greasy particulate matter from having a certain protective effect on viruses and bacteria, but any mask is not 100%. It is recommended to reduce going out as much as possible now. Pay attention to drinking more water, ventilating frequently, washing hands frequently, and keeping the indoor environment hygienic, so as to achieve the normal effect of improving one’s own resistance.
