Regular masks are suitable for children over 3 years old, and it is best not to wear them for children under 2 years old. Children under the age of 2 wear masks, they cannot make the masks close to their faces, and they have no effect.
Also, the better the anti-fouling property of the mask, the worse the breathability. Masks cover the face tightly. Although they can withstand the invasion of bacteria, viruses, PM2.5, etc., it is not good for children to breathe fresh air. Compared with adults, children have poorer lung function.
