The N95 mask is a mask certified by the National Institute of Occupational Safety and Health, which can block 95% of dust particles in the air. The diameter of the dust particles is the smallest. Up to 70-90 nanometers, many of our viruses, especially influenza viruses, the diameter of the new coronavirus is about 60 ~ 140 nanometers. Compared to ours, the diameter of masks that can block particles can be found. Pm2.5 masks, which can block Particles with a diameter of more than 2500 nanometers are completely unable to block the coronavirus, and the diameter of the particles blocked by the n95 mask is exactly the same as that of the new coronavirus. It is also said that the virus spreads with the droplet, as long as it can block the droplet You can stop the virus, let's look at the diameter of the droplets. Most of the diameters of the droplets are about 1.5 microns to 175 microns. In other words, the smallest droplets can also pass through the mesh of PM2.5 masks, and the surgical protective masks and N95 masks we use can block the droplets and thus prevent the virus from spreading.
