What is the micron protection?

Common Misperception
 

There is a common misperception that if people wear a face mask, they will protect themselves. That is only true if one has masks like the N95. We are encouraged to wear face masks in public to prevent US from spreading viruses to others. Since many may be carriers, unknown to themselves since they are asymptomatic, they can spread the virus through talking, exhaling, coughing or sneezing. By wearing a mask, they prevent viruses from becoming airborne. The mask does not protect the wearer unless it is a special mask. If everyone wore a mask in public it would reduce the spread.
