Sneeze and cough droplets are usually between 7 and 100 microns. Surgical ,masks, and some ,cloth masks, will block 7 micron particles but the COVID19 virus particles are 0.06 to 0.14 microns.
Cloth masks, are ineffective as source control and PPE, surgical ,masks, have some role to play in preventing emissions from infected patients, and respirators are the best choice for protecting healthcare and other frontline workers, but not recommended for source control.

Among the three ,cloth mask, types, a ,cloth mask, with an exhaust valve performed best with filtration efficiency of 80-90% for the measured polystyrene latex (PSL) particle sizes. Two styles of commercially available fabric ,masks, were the least effective with a filtration efficiency of 39-65% for PSL particles, and they performed better as the particle size increased.
