Our safety has come to depend upon using breathing masks and understanding ventilation, airflow, and airborne droplet travel, and there are many interesting videos about how masks work (and don’t), led off by an excellent article by Henry Reich’s Minute Physics. His video discusses particle size and motion, and the electret properties of N95 mask fibers for trapping airborne particles. There are several recent studies and articles visualizing and characterizing face mask effects on coughs and sneezes via...
