Thanks for that info. I had thought scents were larger than viruses before you forced me to look it up. FYI covid is approx 100 nanometters. some scents are as small as 1-2 nanometers.

Cough droplets that carry virus are 0.62-15.9 micons (micrometers).

Typical mask if I recall correctly can only block 45micons.
