Disposable medical masks are also fake. You can learn some methods to judge the authenticity of masks. First, you can cut off the mask. The real product has two layers of cloth, one of which is meltblown cloth, which can stop bacteria. Then you can burn the cut mask with a lighter. If the middle layer burns, it is fake. If not, then it is true. Because meltblown cloth will not be ignited, it is also a favorable standard to distinguish between true and false. Finally, you can pour a little water on the mask, and the water will adhere to it and become small drops, which will not leak. If the water leaks immediately, it means it is a fake mask.

When wearing a mask, you can see if there are some anti-counterfeiting marks printed on the mask, which is actually a very simple way to distinguish between true and false. The epidemic has been going on for a long time, and masks have become a necessity in our lives. Whether you go to the supermarket or go out of town, you need to wear a mask and bring more. Because these masks are disposable products, they can't be worn for more than 24 hours at a time, and then they need to be replaced. In fact, people also have their own methods. A real mask is more durable. It can intercept the fog you breathe and form some small water droplets on the inside of the mask.

Some netizens are curious about meltblown fabrics. This kind of cloth is really special. It is usually installed in the middle of a mask to keep out bacteria. The main material of meltblown fabric is polypropylene, which has a high melting index, so there are criss-crossing fibers in it, which can prevent bacteria from spreading in it. The diameter of these fibers is very thin, which is about 1/30 of that of ordinary hair. Netizens can imagine. So many fibers piled together can form a strong barrier, which can reduce the risk of infection after wearing a mask.

From the above description, we know the importance of wearing masks, so masks should become a part of our bodies. Don't forget to wear a mask.
