A hard way is the Gesunheit (II) machine.An easy way to test the effectiveness of these masks at halting the transmission of aerosols is to simply exhale a vape hit through one.
YMMV but with all my masks the aerosol went right through. The two guys I saw wearing paint booth respirators seemed like the most powerful option.
With the abstract of:
We identified seasonal human coronaviruses, influenza viruses and rhinoviruses in exhaled breath and coughs of children and adults with acute respiratory illness. Surgical face masks significantly reduced detection of influenza virus RNA in respiratory droplets and coronavirus RNA in aerosols, with a trend toward reduced detection of coronavirus RNA in respiratory droplets. Our results indicate that surgical face masks could prevent transmission of human coronaviruses and influenza viruses from symptomatic individuals.
