There are many kinds of advertisements for masks How to choose a mask Here comes the guide to avoid the pit! Recently a press conference on the prevention and control of the novel coronavirus KN95 Face Mask with Five Layers epidemic in Beijing warned that key personnel in the takeaway and distribution industry as well as ordinary citizens should wear N95 and KN95 masks when they are in closed and controlled areas or when they go to hospitals to see a doctor and get medicine 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” Or it just looks like KN95 but it’s actually an ordinary mask What if I buy the wrong one and can’t play a protective role For this reason a reporter interviewed experts in related fields to explain how to choose and buy masks for you Popular “3D Stereo” and “4D Stereo” on the Internet Even “5D three-dimensional” masks Will the protection effect be better An insider in the mask production industry said that this kind of propaganda is just a gimmick and its protective effect still depends on the specific quality and performance of the mask
    There are also some businesses playing with the concept Searching for KN95 masks on an e-commerce platform you will find that many mask links are under the banner of “medical KN95 masks” and “medical KN95 protective masks” and publicize that they can “guard against viruses” and “coronavirus protection” These masks are cheap about 10 cents each However these masks sold under the banner of “Medical KN95” are packaged with the words “surgical mask” Many experts have confirmed that KN95 masks are all industrial standards and there is no “medical KN95 mask” An insider in the mask production industry said that this kindof propaganda is just a gimmick and its protective effect still depends on the specific quality and performance of the mask There are also some businesses playing with the concept Searching for KN95 masks on an e-commerce platform you will find that many mask links are under the banner of “medical KN95 masks” and “medical KN95 protective masks” and publicize that they can “guard against viruses” and “coronavirus protection” These masks are cheap about 10 cents each However these masks sold under the banner of “Medical KN95” are packaged with the words “surgical mask” Many experts have confirmed that KN95 masks are all industrial standards and there is no “medical KN95 mask” 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 Surgical mask is a common flat mask in addition flat masks are also divided into medical care masks and non-medical masks Simply speaking these masks have certain protective effects but three-dimensional medical protective masks (N95 mask) and KN95 masks are better than plane masks 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 Therefore when choosing masks consumers should not only pay attention to the introduction of products but also see clearly the implementation standards so that they will not be confused by advertising and choose the type of masks they need more pertinently 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% The actual protection effect may not even reach 60% Expand the full text 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 Surgical mask is a common flat mask in addition flat masks are also divided into medical care masks and non-medical masks Simply speaking these masks have certain protective effects but three-dimensional medical protective masks (N95 mask) and KN95 masks are better than plane masks 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 Therefore when choosing masks consumers should not only pay attention to the introduction of products but also see clearly the implementation standards so that they will not be confused by advertising and choose the type of masks they need more pertinently 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% The actual protection effect may not even reach 60% The choice of masks is not the more expensive the better It’s not the cheaper the better Instead we need to make reasonable choices according to our own actual situation Buy a mask in 3 steps to avoid the pit! Jin Shubin an associate researcher at the Institute of Urban Safety and Environmental Sciences Beijing Academy of Science and Technology said that as a daily protection there is no need to blindly pursue high-level protection capabilities just moderate The choice of masks is not the more expensive the better nor the cheaper the better but a reasonable choice according to their own actual situation Jin Shubin suggested that the purchase of masks to avoid “entering the pit” can be divided into three steps The first step is to choose regular purchasing channels such as chain stores drugstores and online flagship stores and carefully check the factory name address telephone number production date and validity period on the package Generally mask products will be marked with product information on their smallest sales unit and if the information is missing we should be vigilant The second step is to identify the implementation standards There are many standards for masks so you don’t need to be familiar with all of them Just remember that GB is the national standard and YY is the medical and health standard It’s usually right to implement these two standards On this premise you can combine your own specific needs such as the current takeaway riders to wear N95 or KN95 masks you can identify GB19083 GB2626; if it is for children to buy you can choose to implement GB/T 38880 standard masks The third step after getting the mask check whether the product packaging is intact whether the product surface is damaged or deformed if the product has a sealing inspection method you can check by yourself according to the method It should also be noted that hair can affect the fit between the mask and the face In order to get better protection it is not recommended to grow a beard when wearing a high-level protective mask such as KN95 Jin Shubin an associate researcher at the
