It is understood that at present, the purchase channels of N95 and KN95 masks are smooth, the supply is sufficient, and the vast majority of takeaway riders and citizens are also very cooperative, consciously wearing such masks in relevant scenes to do a good job of protection. However, there are a variety of advertisements for masks on some e-commerce platforms, and some consumers reported: “I thought I bought a KN95 mask, but when I opened the package, I found that it was either loose and poorly wrapped, or there was a strange smell that I dared not wear.”.

In the face of a wide variety of mask advertisements, How can consumers refine their “golden eyes”? Choose the mask you need? Li Lin, the head of the enterprise who is very familiar with the whole field of mask production and sales, answered the questions for netizens from four aspects. The first move is to see through the “false concept” of businessmen. Li Lin said that consumers often use masks such as N95, KN95 and surgical mask. Among them, N95 mask is a foreign word, which is not called N95 mask in the strict sense in China, but called medical protective mask; KN95 is a mask produced according to the industrial standard in China, and its protective effect is basically the same as that of N95 mask, except that it does not have the functions of sterilization and blood splashing prevention of medical protective mask.

It should be noted that there is no medical KN95 mask, and there is no “medical KN95 mask”. Li Lin introduced that some consumers encountered the implementation standard of YY0469 three-dimensional mask, but claimed to be KN95 protective mask, although it made a three-dimensional shape, and used the concept of KN95 to publicize, but the actual implementation is the standard of plane mask. Second, in the regular channels, through the implementation of standards to distinguish the performance of masks. Without professional testing equipment, this is the simplest and most feasible way. Li Lin introduced that N95 is the American standard and KF94 is the Korean standard. In China, the national standard for medical protective masks is GB19083, the executive standard for KN95 is GB2626, and the executive standard for surgical mask is YY0469. The model name of the mask is not directly related to its performance, and the steel seal on the mask is not the standard to judge the performance of the mask.

Third, masks with too strong pungent odor should be used with caution. Li Lin said that regular mask products have no smell, or only a slight smell of normal materials. Generally speaking, qualified products produced by regular manufacturers do not need to worry about odor problems. But there are also some substandard products on the market. If you find that the odor is pungent or very uncomfortable after wearing it, the quality of the mask may be problematic. It is recommended that you do not wear it, let alone clean the mask because of the odor, because once the melt-blown cloth, which plays the main protective function of the mask, is damp, it is difficult to play a protective role. Fourth, self-check the tightness of the mask. Li Lin said that even if the quality of the mask is up to standard, the protective mask is not suitable for the wearer’s face shape, which will greatly reduce the protective effect. He admitted that a good protective mask will suit most people’s faces, but there is no mask on the market that can suit all people’s faces. If the mask you buy can’t fit the wearer’s face well, for example, there is a gap in the bridge of the nose or the face, bacteria or viruses will be inhaled from the leaking part, even if the filter rate of melt-blown cloth can reach 99%.
