We both detected the strong smell of aftershave. I recognized the scent because I have a friend who uses too much of it daily. We had our masks around our necks and pulled them up to cover our faces. We could still smell the aftershave for some time as we drove along.

When I got home I did some research. The particle size of the airborne perfumes is between 30 and 150 micrometers. The particle size of the COVID-19 virus is 70-90 nanometers...a nanometer is 1000 times smaller than a micrometer.

I draw two conclusions:
1. Airborne particles can hang around for a decent amount of time
2. If I can smell perfumes through my mask, I can also inhale
COVID-19 particles through it.

Note: I have never assumed that the mask is protecting me, but might be protecting others, but there are many who feel bulletproof while wearing homemade masks.

Masks are not respirators. Gas Scent molecules are smaller than water droplets molecules.
