Be sure to pay attention to the size when selecting. If the size of the dust mask is too large or too small, it will directly affect the filtering effect of the dust mask. You should choose a dust mask based on your baby's age and face size. In general, an 8-10 cm mask is perfect for your baby, and it will be better if it is the right size.
When choosing, you should look at the degree of protection of the dust mask. The focus of the dust mask for children is that the filter rating of the dust filter is KN90 and above. In smoky weather, the KN90 mask and the dust mask on it can be used to achieve protection. There are many dust masks on the market today. When purchasing, please be careful to choose a dust mask that meets the KN90 rating or higher.

When wearing a dust mask with a dust mask, the dust mask is dry and moisture-free, comfortable and hygienic. It can also reduce respiratory resistance, which is good for children's breathing and is more conducive to the healthy growth of children.
