Смысл: The main idea is that face masks are scientifically proven to be ineffective against aerosol-borne respiratory viruses, and their widespread mandate is based on political goals and social psychology rather than clinical evidence.
The author argues that masks cannot stop the tiny aerosols responsible for respiratory infections and that clinical trials prove they do not reduce infection rates in real-world settings.
Смысл: The main idea is that masks with exhalation valves are ineffective for preventing the spread of COVID-19 because they allow unfiltered breath and droplets to enter the environment, unlike non-valved masks which protect the people around the wearer.
NIST research using airflow visualization proves that valved masks do not stop the spread of COVID-19 because they allow unfiltered air to escape.
