N95 mask is undoubtedly a good protective mask, it can filter more than 95% of non-oily particles, but it is not a good choice for anti-smog. The main purpose of KN95 masks is industrial protection, and its implementation standard is GB2626-2006 "Respiratory protective equipment-self-priming filter type anti-particulate respirator", which is developed for protecting mines, cement production plants, electric welding workshops and other industrial and mining workers Industrial protective masks.
N95 masks are too tight and have poor air permeability, which will cause a heavy burden on the human respiratory system, and ordinary people will feel bored and uncomfortable after wearing them for 30 minutes. The elderly, children, or people with respiratory diseases, cardiovascular diseases, and sensitive skin are even more unsuitable.
Even if a mask has a high particulate filtering efficiency, if the respiratory resistance is too large, it is not a good-performance respiratory protection product. For example, the common N95 mask on the market has a good filtering effect, but the respiratory resistance is large, and it is easy to wear for a long time. Causes the human body to lack oxygen and feel uncomfortable. A good-performance respiratory protective equipment must be the final product with high filtration efficiency and low respiratory resistance, both of which are indispensable.
