The model also showed where the particles landed on its face, in nasal passages and how they are distributed in the lungs and pharynx.
Research has determined that a new three-layer surgical mask is effective 65% in the filter particles, but if the mask is worn, this number falls to 25%. In fact, the researchers have found that a worn mask has led the wearer to inhale more particles than those who do not wear any mask at all.

"Our results show that this belief is true only for particles greater than 5 micrometers, but not for fine particles below 2.5 micrometers."

4 Face masks with valves
Researchers at the National Institute of Standards and Technology (NIST) have recently found that facial masks with ventilation valves actually help to broadcast coronaviruses.
