Precautions for use

(1) Respiratory protective equipment includes masks and masks. Wash hands before wearing and after taking off.

(2) Pay attention to the front and back and up and down when wearing a mask. The mask should cover the mouth and nose and adjust the nose clip to fit the face.

(3) Avoid touching the inside and outside of the mask with your hands during wearing, and remove the mask by removing the cords at both ends.

(4) Wearing multiple masks cannot effectively increase the protective effect, but increases the respiratory resistance and may damage the tightness.
