We all know that masks are the most basic protective equipment. They can filter certain viruses and bacteria and prevent infection with the new coronavirus. They are very popular among people, and many people wear masks when they go out. There are good and bad masks on the market, so are masks that break when torn fake? Let's take a closer look! Is it fake that the mask breaks when torn?Not necessarily. However, masks that break easily when torn are likely to be counterfeit and of relatively poor quality. The key is whether you bought the mask from a regular store. For general masks, the performance is determined by the density of the mesh, not its flexibility or whether it can be torn. Therefore, as long as it can block bacteria and viruses, it is a good mask with a dense mesh. Medical masks usually have three or more layers to isolate bacteria and dust. They are disposable, safe and reliable, and there is no risk of secondary infection. A standard surgical mask consists of three layers: the outer layer is a water-blocking layer that can block splashing liquids; the middle layer is a filter layer that can effectively block particles of 0.3 to 1. Opm; the inner layer is a water-absorbing layer that can absorb moisture from the wearer's mouth and nose. It must also be equipped with a nose clip and a tie. The most common type of surgical mask is non-woven fabric with two ties. How to distinguish true and false masksUsually, the product registration number will be marked on the outer packaging of more formal medical surgical masks. The numbering rule is usually: X醫藥注册准 (X is the abbreviation of each province, such as Hubei, Zhejiang, Guangdong, etc.) + registration year + 264 (indicating that it belongs to Class II medical device 64 classification) + number. It can be identified through the website of the State Food and Drug Administration: 1. Log in to the State Drug Administration http://www.nmpa.gov.cn (gov means the official website of the government) 2. Click on the medical device query and choose whether it is a domestic or imported device based on the place of origin of the device you purchased. 3. Enter the registration certificate number, which is the part with X械注册准+201XXXXXXXX. 4. Choose the corresponding product according to the place of origin. 5. When you click in, you should mainly look at two places. One is the product name. If it shows as a medical surgical mask/medical protective mask, then you can use it with confidence. If it does not contain the words "medical surgical", such as "disposable non-woven medical mask", "disposable medical mask", "ordinary medical mask", etc., which do not contain the word "surgical", they are not officially recommended medical surgical masks, and medical does not mean surgical use. The second is the production standard. The production standard for medical protective masks (KN95/N95) is GB19083-2010, the standard number for medical surgical masks is: YY0469-2011, and other anti-smog standards are GB2626-2006. Generally, industrial-grade protective masks are sufficient to prevent droplets. Key points for buying masks1. Purchase masks that are packaged and have medical device registration information on the packaging; 2. Pay attention to the product logo and check whether the product name, production date, factory name, factory address, shelf life, product instructions and other information are clearly marked; 3. Try it on first to choose the style and model that suits you. Before using a certain type of mask for the first time, you need to try it on first by referring to the instructions. Taboos for buying masks1. Do not buy masks if the operator cannot provide purchase receipts; 2. Do not buy masks without factory name, address and health license number (medical devices without registration information) or without packaging; 3. Try not to buy masks with foreign language packaging and no Chinese labels in China; 4. Do not buy masks that do not meet hygienic packaging or whose packaging bags are not sealed; 5. Do not buy masks with fewer layers than indicated on the packaging. |
