Wear a mask when it is necessary You should wear a mask during flu season, haze, sandy weather, sickness and when you go to the hospital. In winter, it is best to wear a mask when going out for the elderly with low immunity and the weak and sick. 2. Don't prefer colored masks Fashionable color masks are mostly made of chemical fiber fabrics, which have poor air permeability and chemical irritating odors, which are easy to cause damage to the respiratory tract. Qualified masks are made of non-woven fabric and meltblown fabric. 3. Don't put it around It is unscientific to put them in random after use and not clean them in time. After wearing a mask for 4-6 hours, many germs will gather. After wearing it, you should fold the mask first, fold the side close to the nose and mouth when folded, put the mask in a clean bag, and finally put it in a bag or pocket. 4. Don't run with a mask Many friends who love outdoor sports often do sports. In order to prevent smog or COVID-19, some people may choose to wear masks to continue. However, the doctor suggested: Because the demand for oxygen during outdoor exercise is greater than usual, masks may cause poor breathing and even hypoxia in the organs, which can have very serious consequences. 5. Don't affect the line of sight After wearing the mask, it should be able to cover most of the area below the mouth, nose and eye sockets. The edge of the mask is close to the face, but be careful not to affect the line of sight. FAQ 1.Where is your factory located? How can I visit to your factory?
