Have you stepped on these ＂thunders＂ about masks?(2)
5. I feel that wearing a few more masks will improve the protection
Some friends feel that the people are denser when they are on the train, so they wear 2 masks directly. However, wearing multi-layer masks will not increase the filtering capacity, but will also increase the breathing resistance, which will cause some discomfort. Therefore, wear the mask correctly and wear it. Just one, don’t wear too much.
In addition, children need to wear masks that meet their age. Do not wear other types of masks. Children should wear child masks. Children under 3 years old are not recommended to wear other types of masks.
