When wearing a mask, note that the purpose of the mask is to prevent droplets from splashing onto the face, first of all the mask should cover most of the area below the eyes, it should be roughly from below the eyes to the lower jaw, and on both sides as far as possible to the cheeks. After the mask is put on, you need to press the nose clip against the shape of your nose, and wipe it down from the top to ensure that all the places fit until the lower jaw. Generally speaking, ordinary medical masks and N95 masks are easy to do this, but other masks do not have a nose clip, if you want to replace it, you can use tissue paper or gauze to pad up the concave and convex areas of the nose as much as possible. The most important thing to keep in mind for children is that since there are no particularly appropriate related masks for children, and it is recommended that they do not go to a place where the infection is concentrated, you can use a regular surgical mask or a regular medical mask that will fit the child’s face more easily, and if the size is not right, you can make an approximate face seal by simply tightening the drawstring at the back.
