As the environment gets worse and worse, many people are used to going out with a mask. Many people choose a disposable mask. Choosing masks is often confusing for many people.. There are many people who don't know how to distinguish between the front and the back of the mask. I will introduce it to you today:

Usually, the disposable face mask we buy at the pharmacy is a medical general surgical mask. It has two sides, the darker side - the blue side faces outward, and the lighter side faces inward, close to our face. Not only that, but the mask is also divided into upper and lower parts. The hard side of the metal strip is the upper end, and it is close to the bridge of the nose when worn.

After understanding how to distinguish between the front and back of the face mask, let's learn how to wear the it correctly.

Second, hang: put the mask on the face and nose, use both hands to hang the rope at both ends on the ear;

Third, pull: both hands up and down to pull the wrinkles of the face mask, so that the face mask can completely cover the nose and mouth;
