Reasonable selection and wearing of masks is an important means to reduce “pathogen” exposure and reduce the risk of infection. So, how should I choose and wear a mask correctly? Do I have to choose a N95 mask? Need to choose activated carbon?
Medical surgical masks are similar in appearance to medical masks. The former is produced in accordance with the pharmaceutical industry standard (YY0469-2011 Medical Surgical Masks). When you buy, you can ask the pharmacy for details or check the instructions carefully.
The other is the N95 type mask, which is often used to prevent haze and has a better anti-virus effect than medical surgical masks.
Step 2: Pull the mask flat with both hands, aiming at the face. Note that the top edge of the mask is 1cm away from the eyes.
Step 3: Press the mask lightly on the bridge of the nose with your left hand. At this time, make sure that the bridge of the nose is in the center of the mask. Use your right hand to hang the mask strap to the back of the ear, taking care to hang it at the base of the ear, otherwise it will easily fall off.
Step 4: Use both hands to hold the edge of the mask tightly against the face. Many masks have a small metal strip that can be fixed and fixed. This is the nose clip. When wearing a mask, let the nose clip bend and fit on the bridge of the nose, so as to ensure the tightness of the mask.
Step 5: Make sure the mask completely covers the nose and mouth. Adjust the position of the mask, the correct coverage is from the chin to 1CM under the eyes.
