Masks are commonly used protective tools in our daily lives. Although it is small and not expensive, it does bring protection to the human body, so more and more people choose to wear a mask when traveling.
Many people may think that dust and bacteria in the air can only be protected by wearing a mask. In fact, this is a wrong idea, because dust and bacteria are tiny particles that may spread in the air, so we should pay attention to some things before and after wearing a mask to ensure the protection of the mask.
Using masks: precautions before and after
(1) Press the nose clip with both hands. Squeezing the nose clip with one hand will make the nose clip appear sharp, causing air leakage and reducing the protective performance of the mask.
(2) Every time you put on a mask, you must perform an air tightness check and exhale at a depth of 33,360. If you feel that the nose clip is leaking, the mask manufacturer should readjust the nose clip according to the wearing procedure. If you feel gas leaking from both sides of the mask, please further adjust the position of the upper strap to the back of your head. If you feel air leakage from your chin, please further adjust the position of the lower strap.
(3) When wearing a mask, Peng glasses fogged, which also shows that the mask is not suitable and the effect of the mask is not good, so the nose clip must be readjusted.
