Anti-fog masks have strict requirements on size and disinfection. Many masks are not supported by pure cotton yarn and contain many polyester fibers. Some of them have only 2 to 4 layers of light isolation gauze, making it difficult to effectively filter viruses and dust in the air. Wrapped on the face with precision and comfort, the air in the cavity is sucked into the human body without filtering.
Improper use of masks:
1. Nostrils are exposed outside the mask. This loses the mask as a “barrier” to protect the respiratory tract. After wearing it, it should cover most of the mouth, nose and orbit.
2. Hang the mask on your ear or chin. Hair, chin, and neck are exposed to the air. The contaminated dust and bacteria are likely to get into the inner layer of the mask. The next time you wear it, it will easily cause respiratory infections.
3. Wear a mask for a long time and do not take it off. If you wear a mask for a long time, the nasal mucosa will become fragile and the original physiological function of the nasal cavity will be lost. Masks can only be worn in special environments. For example, in the winter season when influenza is epidemic, masks should be worn in public places where there may be a large number of germs.
The above is the phenomenon of improper use of masks introduced by mask manufacturers. I hope you can avoid them when using them.
