Can wearing a mask prevent smog?

 

Wearing a mask can prevent smog.

 

When wearing a mask, it can reduce the exposed area and filter the pollutants in the air, so it can prevent smog. However, wearing masks to prevent smog requires careful selection of masks. Not all masks have the effect of preventing smog.

 

What mask to wear to prevent smog

 

KN90 and KN95 masks.

 

If the mask has a filtering capacity of 90% for fine particles with a diameter of 2.5 microns or less, this type of mask is called a KN90 mask. If the filtering capacity reaches 95%, it is a KN95 mask. This kind of professional mask can effectively prevent haze and virus. Correspondingly, the breathability of this kind of mask is not good. If the breathing rate is too fast, it is easy to cause breathing difficulties.
