Original Note:
A sneeze generates droplet nuclei ranging from 0.125 μm to 10 μm with a median size of 1 μm, which N95 masks can trap with 95% to 99% efficiency. Human olfactory receptors can detect smell from much smaller molecules, such as sulfur, with an approximate diameter of 0.0004 μm. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7447000/
