Original Note:
The point of the masks isn't to catch individual SARS-CoV-2 virus particles, because virus particles don't travel through the air by themselves. They travel inside respiratory droplets, which are many times larger. It's the droplets that are easily caught by masks. https://www.ucsf.edu/news/2020/06/417906/still-confused-about-masks-heres-science-behind-how-face-masks-prevent https://www.nytimes.com/interactive/2020/10/30/science/wear-mask-covid-particles-ul.html
