1. Look at the product registration number:

The product registration number is usually marked on the outer packaging of more formal medical surgical masks, and the numbering rule is usually: X machine injection (X is the abbreviation of each province, such as Hubei, Zhejiang, Guangdong, etc.) + registration year +264 (representing Belongs to the second category of medical devices 64 classification) + number.

It can be identified by going online and entering the website of the State Drug Administration. If the query result shows that it is a medical surgical mask/medical protective mask, then you can use it with confidence. If it does not contain the word "medical surgical", it may say "disposable non-woven medical mask", "disposable medical mask", "general" "Medical masks" that do not contain the word "surgical" are not included in the officially recommended medical surgical masks, and medical treatment does not mean surgical treatment.

2. Look at the production standard:

(KN95/N95) The production standard is GB19083-2010, the standard number of medical surgical masks is: YY0469-2011, and other anti-haze standards are GB2626-2006, generally industrial-grade protective masks are enough to prevent droplets. If the production standard of the mask does not meet the above standards, then the mask is a fake.

3. Look at the thickness:

Disposable medical masks have three layers, from the outside to the inside are the waterproof layer, the filter layer, and the comfort layer, and they are divided into a white surface and a blue surface. The fake masks are relatively thin, and some have only a thin layer, which is very light-transmitting, and there is no blue and white sides.

4. Smell the smell:

Real masks have to undergo strict disinfection treatment before they leave the factory, and they generally have no other peculiar smell. However, if it is a low-quality counterfeit product or a recycled product, it will generally have a strong pungent odor.

The true and false of masks are related to our lives and health. We should keep our eyes open when buying disposable masks to avoid buying low-quality counterfeit products. In addition, whether you are buying domestic masks or purchasing foreign masks, you must buy them from trusted sources.
