There are three most important points when choosing a mask:
- Very good filtering capacity
- Very good facial fit
The bridge of the child’s nose cannot be pinched tightly; when talking and blowing, the cheeks will also bulge (it may bulge without speaking). Every country has masks that correspond to certain standards. What about masks that can prevent new crowns and smog? When choosing a mask, you must choose a mask that suits your baby’s face shape and size. Only a high degree of fit can achieve a certain preventive effect. In general, KN95 (China), KF94 (South Korea) and DS2 (Japan) standards are very close, and both have children’s masks that meet standards. These three standard children’s masks, if you worn correctly, can prevent new crowns and prevent smog.
