Industry insiders suggest that masks for ordinary people do not need to be used and replaced again. Nowadays, its sales volume in the market has always been good. People can wear ordinary disposable masks and wear them when going out. Especially in densely populated confined spaces.

　　Wash hands before and after wearing. When wearing a disposable mask, pull the elastic band on both sides of the ear, fix the bridge of the nose, and pull the mask to the chin. Under normal circumstances, avoid touching the mask surface with both hands to reduce pollution. When not in use, you can take it off (dark side out) and store it in a clean and breathable container, such as a paper bag, or hang it (dark side out) and put it on again after it is taken out, but it can be changed every day.

　　What if I can't buy it? After each use, disinfect with alcohol first, then wrap it with paper towel or hang it on the wall. Healthy people can use 1 to 2 tablets a day without changing each time.

　　In addition to wearing disposable masks, you should also pay attention to washing your hands. Don't dig your nostrils and rub your eyes. The dark waterproof layer is outside the wet layer, and the hydrophilic layer faces inward. If there is dirt or moisture, its protection will be greatly ineffective, and it needs to be replaced at this time.
