Common types of masks include regular masks, medical masks, surgical masks, and protective masks. How do you choose a mask that is suitable for you? How do you wear a mask correctly? Let's explain it to you below.
1. Types of masks and their protective effects: Protective masks > Surgical masks > Regular medical masks > Regular masks
2. Regular masks (such as cotton, sponge, activated carbon, gauze) can only prevent dust and haze, but cannot prevent the spread of bacteria and viruses.
3. Regular medical masks: Can be used in public places with low population density.
4. Surgical masks: Have better protective effects than regular medical masks and can be worn in crowded public places.
5. Protective masks (N95/KN95): Used by frontline medical staff when in contact with confirmed or suspected COVID-19 patients, in fever clinics, during on-site investigations, and by sampling and testing personnel. They can also be worn in densely populated areas or enclosed public places.
6. For the prevention of recent novel coronavirus pneumonia, medical masks should be used, and regular masks such as cotton, gauze, and activated carbon should not be used.
