December 07,2021

The outbreak of COVID-19 has caused a strong operation against viruses. The most obvious behavior is to panic buying masks online and in pharmacies. But can you wear a mask? How should masks be worn to completely block bacteria and viruses?




What are the categories of masks?


First of all, many people see that there are N95 and KN95 on the Internet. These are only two different national implementation standards. The Chinese Standard is KN, while N is the American Standard. The two are the same.


The most common masks mainly include three categories: medical-surgical masks, medical protective masks (N95 masks), and ordinary cotton gauze masks.


How should I wear a mask?


  • Medical masks and surgical masks


Cover the nose, mouth, and chin with the mask. The upper belt of the mask is tied in the middle of the head and the lower belt is tied behind the neck;


Then put the fingertips of both hands on the nose clip and shape the nose clip according to the shape of the bridge of the nose;


Check whether the edge of the mask fits the face.


  • Medical protective mask


Hold the protective mask with one hand and back the side with nose clip outward;


Then cover the nose, mouth, and chin with the protective mask. The nose clip is close to the face upward, and pull the lower tether over the head with the other hand and put it under the ears behind the neck;


Then pull the upper tether to the middle of the head, put the fingertips of both hands on the metal nose clip, start from the middle position, press the nose clip inward with your fingers, move and press to both sides respectively, and shape the nose clip according to the shape of the bridge of the nose.


  • How to take off the mask?


Do not touch the front of the mask (contaminated surface). When removing the mask, first untie the lower tether, and then untie the upper tether;


Then hold the strap of the mask with your fingers and throw it into the medical waste container.


Wash your hands after taking off the mask.


Precautions for wearing a mask


✅Term of validity


The validity period of the medical-surgical mask is three years and that of the medical protective mask is five years. After the validity period is exceeded, the filtration efficiency and protective performance will be reduced, which can not effectively block the infection of viruses and bacteria.


Wash hands before and after wearing


Wash your hands before wearing the mask to avoid touching the inner surface of the mask. Try not to touch the mask during use. Try not to touch the outside of the mask when taking off the mask to avoid bacteria from touching your hands. Wash your hands after taking off the mask.


Don't wear masks for a long time


Wearing a mask all day is easy to make the nasal mucosa fragile, lose the original physiological function of the nasal cavity and reduce resistance. It is not recommended to wear a mask for a long time in a well-ventilated place.


Keep medical masks properly when not in use


To avoid secondary pollution, be sure to fold it into a clean self-sealing bag, and fold the side contacting the mouth and nose inward.


The above are some skills in the selection and use of masks. Have you all learned it? In the face of the COVID-19, you should not operate blindly and deal with it sensibly to ensure that you are better protected!
