It is understood that the implementation standard for medical protective masks is GB 19083-2010; the implementation standard for medical surgical masks is YY 0469-2011; the implementation standard for disposable medical masks is YY/T 0969-2013. Some products claiming to implement the enterprise standards (YZB) formulated by the enterprise themselves are also available for purchase. In principle, the technical requirements of the enterprise standards are not lower than the national standards (GB) or industry standards (YY).

In addition, the product registration number will be marked on the outer packaging of medical masks that are subject to medical device licensing supervision. The numbering rule is usually: Guangdong and the like) + registration year + 264 (indicating that it belongs to the 64 classification of Class II medical devices) + number. Citizens can inquire and identify through the National Medical Products Administration website.

If the product name shows "disposable medical mask", "medical surgical mask" or "medical protective mask", then it falls within the scope of medical masks; if it does not contain the word "medical", like "Disposable non-woven masks", "ordinary protective masks", etc. that do not contain the word "medical" do not fall within the scope of officially registered medical masks.

Purchase and identification of non-medical masks

For non-medical masks, the consumption guideline points out that citizens can check whether the relevant information and requirements on product labeling and packaging are complete and accurate.

For example, for KN/KP series masks whose implementation standard is GB 2626-2006, the product name, trademark, model, implementation standard and other information must first be marked on the product. In addition, the filter material level should also be marked. The level is marked with a combination of standard number and filtration level, such as GB 2626-2006 KN90, and generally there are only six filter material levels: KN90, KN95, KN100, KP90, KP95, and KP100.

In addition to marking the above information on the product, the minimum sales package should at least be marked with the product license number, production date or production batch number, storage life, recommended storage conditions, etc. in a clear and durable manner in Chinese. . The daily protective masks whose implementation standard is GB/T 32610-2016 require that each mask should be sealed and packaged, and each packaging unit must have an inspection certificate. In addition to marking the manufacturer, product name, specification, implementation standard, and protection effect level in obvious parts , instructions for use (wearing method, precautions, etc.), the main raw materials of the product (inner layer, outer layer, filter layer), production date, recommended use time and storage period, disinfection method (such as disinfection), etc.

In addition, citizens also need to see whether the standards match. If the product name and execution standards do not match, please choose carefully. The implementation standard for anti-smog masks (PM2.5 masks) for daily protection is GB/T 32610-2016; the implementation standard for industrial dust masks (KN95/KN90) is GB 2626-2006. KN95 refers to the filtration efficiency of non-oily particles ≥95%. This type of mask can also achieve the effect or requirement of preventing droplets; and the N95 mask that people often call is in compliance with the requirements set by the National Institute of Occupational Safety and Health (NIOSH) Standard masks, the American N95 is equivalent to the domestic KN95 standard.

Selection and identification of imported masks

Imported masks mainly depend on the product label. The consumer guideline states that in principle, imported masks sold in the domestic market should be labeled with corresponding product information in Chinese.

When purchasing or ordering mask products from abroad, be sure to choose formal channels with reliable sources to ensure product quality. At the same time, for masks purchased from abroad, first look at the product logo. There may be no Chinese logo. You can check the database according to the public information on the product, or you can check the product registration certification on the official websites of relevant regulatory agencies and certification agencies in foreign countries. Information (such as www.cdc.gov; www.fda.gov, etc.), if the registration number cannot be found, it must be a fake product.

If you want to know whether the imported N95 you purchased is a regular product, you can check whether the product company name and product model are consistent on the US Centers for Disease Control and Prevention website. Only N95s that are approved by both the National Institute for Occupational Safety and Health (NIOSH) and the U.S. Food and Drug Administration (FDA) are medical N95s.

Different countries and regions have their own mask standards. For example, the N series is the American standard, the KF series is the Korean standard, the FFP series is the European standard, the DS series is the Japanese standard, and the P series is the Australian standard. The larger the number, the higher the protection level. .

In addition to "debating" when choosing a mask, you can also see and smell it

It is understood that different types of masks are used by different groups of people in different scenarios. In principle, if possible, it is best to use medical surgical masks and KN90 or above dust masks, but in environments where there are no confirmed or suspected patients, ordinary disposable medical masks will suffice. However, if you go to the hospital, it is best to increase the level of protection. It is recommended to use medical-surgical masks, KN95 masks or masks with a higher level of protection. The consumer guide points out that in addition to understanding mask product information, you can also check the appearance, material feel, and smell of the product to avoid buying fake and shoddy products as much as possible.

It is understood that when selecting a mask, you should pay attention to the appearance of the mask. The surface of the mask is clean and even, without damage or stains, and the size is consistent with the size specified in the standard. Some masks imported from abroad and masks sold separately do not have outer packaging information, which can be judged from the material and feel of the mask. Fake and shoddy masks are generally thin, with only one layer, or three layers but the middle layer is not melt-blown non-woven fabric; regular and qualified medical masks have at least three layers, and the outer layer feels smooth. If you cut it, you will see obvious three layers. Structure, poor light transmittance and no obvious weaving.

In addition, normal masks should be odorless and tasteless. Try not to buy masks with pungent or unpleasant odors, and be careful when buying masks with too strong fragrance.

Thin and translucent masks have poor protective effect

The higher the airtightness of the mask, the better?

It is worth noting that the consumption guideline points out that people and children with poor cardiopulmonary function or basic respiratory diseases are not recommended to wear masks with high airtightness such as medical protection or industrial particle protection to avoid wearing them. Unexpected situations such as hypoxia, dizziness, etc. are prone to occur.

Ordinary consumers do not need to use medical protective masks for daily use, and should be given priority to front-line medical staff;

It is not recommended that children wear adult masks with tight fit requirements Masks, because children's faces are smaller, are difficult to fully seal with the edges of the relevant masks.

At the same time, parents should pay attention to the wearing condition of children's masks. If they feel uncomfortable, they should adjust, replace or even stop using them in time.

In addition, given the current large consumption of masks worldwide, the shortage of masks will continue, and reasonable and limited reuse is necessary. But at the same time, we should also pay attention to:

First, if the mask has been used for a short time and does not become obviously dirty, deformed, or smelly, it does not need to be replaced every four hours;

Second, the mask is only It can be reused to a limited extent, provided that it has not been worn for a long time and there is no contamination. If you have experienced higher exposure risks, including wearing masks in high-risk areas such as hospitals, you must discard them promptly after returning home. Remember to spray alcohol and other disinfectants before discarding. ;

Third, masks intended to be reused can be disinfected by sunlight or ultraviolet light after removal. After disinfection, they can be hung in a clean and ventilated place, or stored in a clean paper bag (keep them dry to maintain the filtration of the mask as much as possible) performance) and cannot come into contact with other masks.
