What are the differences between children's masks and adult masks?

In addition, apart from the difference in size and function, the materials of children's masks and adult masks(Earloop Face Mask On Sales) are different. Most children's masks are made of cotton, and because babies' breathing strength is weaker than that of adults, the number of layers of children's masks is relatively small, and the protective power will be weaker. The breathing resistance design of adult masks and children's masks are not the same. The cardiopulmonary function of adults is stronger than that of children, so adult masks will have stronger respiratory resistance, while children's masks will be designed to be relatively small in terms of resistance to respiratory resistance and are more suitable for children to wear. Therefore, it is best to choose a mask that matches the age.
