In addition, there are a variety of stars on the market often worn cotton masks, sponge masks.

It is good for citizens to choose medical surgical masks for daily protection. The N95 mask is more effective in preventing disease, but it is not suitable for long-term wear due to its poor air permeability and high respiratory resistance.

When wearing the mask, the folded face will be fully expanded, the mouth, nose, chin completely covered, and then press the nose clip, so that the mask and the face completely fit.

Wash your hands before wearing the mask or avoid touching the inside of the mask while wearing it to reduce the risk of contamination.
