Shanghai men spent more than 4 million yuan to buy masks. How to identify the quality of masks?

For masks, when novel coronavirus broke out, masks were very necessary for any country. When China firmly controlled novel coronavirus, masks played a vital role, and the quality of masks was very important. This time, people will wonder that the masks bought by men in Shanghai are not up to standard. How to identify the quality of masks? In fact, from my point of view, I think we can feel the quality of masks by touching them. At the same time, we will also find that some inspection agencies will be more complicated in the quality of masks, and the quality of masks can also be felt on the back of masks. Let's analyze it in detail.

1: You can feel it yourself:

First of all, the simplest and most intuitive way is to feel the mask when we buy it. Generally speaking, the density of the mask is relatively high, and we will feel uneasy when we feel it. At this time, the quality of the mask is proved to be good. If we don't feel anything and it's thin, the quality of the mask must be very poor, which is the so-called inferior mask. It is meaningless to buy this mask, because it can't protect our basic safety at all. An excellent mask can isolate many viruses, especially novel coronavirus, which plays a vital role in stabilizing the epidemic.

2 inspection agencies should strengthen the audit:

At the same time, any masks that are sold again will definitely be reviewed by the procuratorate. Therefore, I think the police should strengthen the audit in this respect, and each mask should be put into use after it meets the standards in all aspects. He doesn't have any information behind many masks. Generally speaking, this kind of mask is produced and sold by himself. He just earns our money, and his body standard can't be reached at all. So we don't want to buy this mask when we see it.

Finally, I think any mask, he can kick out some mask information and standards behind his back, giving us a reassuring attitude. After all, masks are not expensive, but they play a great role in our lives. Especially during the novel coronavirus period, our country did control novel coronavirus steadily, but it doesn't mean that the strategy excluded novel coronavirus. Therefore, masks still play a great role in our lives. No matter by train, subway or bus, we all wear masks, so the quality of masks should really be strengthened.
