Original Note:
First, mists such as those being shown in this demonstration are smaller than viruses and so this doesn't prove that masks don't block microbes. This article is a great primer on this: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7447000/ Second, masks are effective at stopping the spread of covid-19 https://www.mayoclinic.org/diseases-conditions/coronavirus/in-depth/coronavirus-mask/art-20485449
