Efficacy of facemasks
The physical properties of medical and non-medical facemasks suggest that facemasks are ineffective to block viral particles due to their difference in scales [16], [17], [25].
According to the current knowledge, the virus SARS-CoV-2 has a diameter of 60 nm to 140 nm [nanometers (billionth of a meter)] [16], [17], while medical and non-medical facemasks’ thread diameter ranges from 55 µm to 440 µm [micrometers (one millionth of a meter), which is more than 1000 times larger [25].
Due to the difference in sizes between SARS-CoV-2 diameter and facemasks thread diameter (the virus is 1000 times smaller), SARS-CoV-2 can easily pass through any facemask [25].
Stanford study quietly published at NIH.gov proves face masks are absolutely worthless against Covid

Uh oh!! 😳. So, how many masks do I need to wear?
ETA: as an entrepreneur, I've just realized a business opportunity. A cellophane mask company. "Our masks stop COVID dead!"

All I know is the world is full of a lot of maskholes and they aren't given up easily. After all, our President is one along with his 80 million voters Pretty sure they will fall back on aerosol droplets and mists
The Stanford Study will still disagree.
