“There is no study in the world that shows that masks work that well,” Dr. Ashish Jha, the White House’s COVID-19 coordinator, said during a recent discussion with the Philadelphia Inquirer.
“So you’re never going to get the kind of benefit from mandatory year-round masking as you would from making substantial improvements in indoor air quality, plus it’s a lot easier to implement as well,” Jha added. “So this is an area where we’re doing a lot and trying to really encourage people to use the resources they have to make those investments and start really improving ventilation filtration in buildings.”

As of February 2021 it was calculated that there were 2 billion billion (2 quintillion) SARS Covid 2 particles in the world.
That incredibly huge number of virus could fit in a single coke can.
The webbing of a mask would need to be so tight that it would suffocate the wearer, to contain something so incredibly tiny.
