There have been a few threads recently where the idea of two, three, four, or more masks be used, and now I want to know how the math works. If the holes or pores on a mask that are intended to trap a virus are 1000 times larger than the virus, how would one calculate how many times larger the effective holes would be for two, three, four, or more masks stacked together? It gets complicated for me when I take into account that the distance between the stacked masks is probably at least 1000 times larger than the virus.
