The mask I bought yesterday is a bit thin. Is a thin mask like this useful? How to choose a mask when buying a mask? Let's take a look together.

 

Is a thin mask useful?

It can only protect against dust. The thin masks bought on the market do not belong to medical masks. They are just ordinary disposable masks, which generally have only one filter layer. Thin masks do not have any protective effect against viruses, and can only be used to block dust and impurities in daily life. Such masks are generally suitable for electronic factories, stamping hardware, catering services, environmental cleaning and other personnel.

Can a two-layer thin mask protect against viruses?

No. Thin masks will not provide any protection against the virus, even if you wear two masks, they will not be effective. Because this kind of thin disposable masks are generally made of non-woven fabrics, the material of this kind of non-woven masks has relatively large gaps in the middle structure and strong air permeability, so there is basically no blocking ability against viruses, even if you wear two The virus can still invade the respiratory tract. In addition, wearing two masks will affect the air tightness of the masks, which will cause more air leakage. At the same time, it will increase the body's resistance to exhalation, making people use more breathing and more likely to be infected. It is better to wear a special medical mask directly.

 

How to choose when buying a mask?

Do not buy Sanwu products.  The most important thing when buying masks is that you cannot buy Sanwu products, because Sanwu products are often of substandard quality, without quality assurance, and may not be able to get up after use. Protection effect. Therefore, when buying masks, you must go to a regular pharmacy to buy them. Correctly choose the type of mask. Masks are divided into medical and non-medical masks. If you need to rely on masks to prevent viruses and bacteria, it is recommended to choose medical masks. If it is for ordinary dust and haze, use ordinary masks, or use the kind of masks with activated carbon.

 

How long can the mask be used after opening the package?

It depends on the situation. How long an opened mask can be stored is determined by its storage method. If the remaining mask is not taken out of the original packaging after the mask is opened, and it has been sealed and packaged all the time, it can generally be stored if the temperature and humidity are suitable. About half a year. If the mask is left unsealed after opening, it is recommended to use it within 1 month, because the longer the mask is left, the more likely it is to be contaminated.
