According to Shangguan news, according to China's national standard "gb2626 respiratory protective equipment self-priming filter particulate respirator", the filter elements of filter respiratory protective equipment can be divided into kn and KP according to their filtering performance. For microorganisms, just look for kn, and the number "95" refers to the level of filtration efficiency. The kn mask only tests the filtration efficiency of particulate matter, and does not test the synthetic blood penetration, surface moisture resistance and other indicators. Therefore, this type of mask can be used to block viruses for a short time, but it can not be used to contact patients who may splash or contact patients for a long time. The N95 mask is a kind of mask that meets the American standard, and the medical protective mask in China is a kind of N95 mask. According to CCTV Finance and Economics, medical N95 adds hydrophobic layer on the basis of particle blocking ability, which can prevent liquid splashing, especially when doctors perform intubation and other operations, it can play a more effective protective role. N95 series masks (N99, 95, 90) have the strongest protective ability, but their air permeability is relatively poor, and they are easy to lack oxygen after long-term use, so they are suitable for healthy people with high epidemic prevention requirements.
