1. One-time wear multi-layer N95 mask
In fact, wearing multiple layers of N95 masks at one time is not necessary, but harmful: one is that it affects the air tightness and leaks more; the other is that breathing is blocked, and it is more likely to be infected if you inhale hard.
Ordinary people usually wear one disposable N95 mask.
2. Throw away immediately after using it once
If there are not enough N95 masks at home, there is no need to change them every 4 hours, and there is no need to drink saliva and throw them away immediately.
Use disposable N95 masks in places with lower risks. N95 masks can be reused if they are clean and structurally complete, especially when the inner layer is not contaminated.
3. Disinfect N95 masks with alcohol
N95 masks can protect against viruses because the virus will form small particles with liquid droplets, which are attached to the N95 mask. Spray the surface of the N95 mask with alcohol. When the alcohol evaporates, the water inside will be taken away. When it is used again, the separated virus may be inhaled.
After the N95 mask is taken off, if there is no obvious pollution, it can be dried directly in a clean, ventilated place, or stored in a clean and ventilated paper bag.
4. Touch the outside of the N95 mask when taking off the N95 mask
We use N95 masks to block droplets. If you remove them directly with your hands, it is equivalent to opening the channel for contact transmission. The hands may be contaminated on the outside of the N95 mask. If you forget to wash your hands, touch your nose and rub your eyes, the virus will enter the human body unknowingly.
★Hold the ear lanyard and take off the N95 mask.
★Because the front part of the N95 mask has been contaminated, remember not to touch it when you take off the N95 mask.
★Wash your hands after taking off the N95 mask, and try not to take off the N95 mask without washing your hands.
5. Wear N95 masks wherever you go
Whether to wear an N95 mask should be considered based on the risk of personal exposure to the disease.
★For healthy adults, if you are alone, such as driving by yourself, doing activities at home, in an open and ventilated place, and there is no intensive contact with people, you do not need to wear an N95 mask.
★In elevators, taking public transportation, in crowded places such as shopping malls and supermarkets, people who are in contact with home isolation personnel and close contacts, and those engaged in high-risk occupations, N95 masks must be worn throughout the process.
