We can see many types of masks on the market. Chengge also introduced them in previous articles. If you are interested, you can have a look. In fact, whether it is a mask or an ordinary mask, we can distinguish from the protection level. The masks is higher than that of ordinary masks. Medical mask with higher standards implemented, and also play a better role in epidemic protection.But the names of masks on the market are variouse. , such as disposable masks, disposable masks, disposable protective masks, etc., it is difficult for ordinary consumers to distinguish the difference.

In fact, no matter what the name is, just be attention to the "implementation standard", you can distinguish:

Take a look at the side attached to the face is shiny and free of broken hair (broken hair, stains, yellowish, and the color cast is a defective product);

Second, touch the whole mask to see if it is soft and smooth, not rough (the fabric is hard, the light transmittance is too thin, and the roughness is a defective product);

Three smells, whether there is any odor on the fabric surface and the hanging ear strap (if there is any odor, it is a defective product);

Four wearing, wearing to stop the ears, whether the nose and face are itchy (if the ears are itchy or itchy, it is inferior).
