What are the rumors of clearing the lungs and detoxifying in foggy weather?

Smog is a fine particle with a particle size of about 2.5 microns, so professional respiratory protection should be done. Wear a suitable dust mask.

Medical research shows that all health care products and foods under the banner of completely curing smog and respiratory diseases are unreliable. For example, fungus and tremella can only moisten the lungs, but not clear the lungs.

1, the dust-proof efficiency of dust-proof masks, we must look for respiratory protective articles produced by regular manufacturers that meet the national standard grade, KN 100 grade, KN95 grade, KN90 grade, which do not meet the standard grade, and the dust-proof efficiency cannot be guaranteed;

2, the tightness of the mask, different people have different faces and sizes, so the dust mask must be divided into sizes to better fit the face of people and maintain good tightness;

3, respiratory resistance should be small, negative importance should be light, no odor, no irritation, no toxicity.
