This is mostly excellent, thank you, but you’re repeating the error that aerosols are particles less than 5 microns. Particles as large as 100 microns can remain suspended in the air. See Jose-Luis Jimenez, Kimberly Prather, Linsey Marr, and this summary in Wired. https://www.wired.com/story/the-teeny-tiny-scientific-screwup-that-helped-covid-kill

Exactly. If we were *all* wearing comfortable N95s which are fantastic for filtering floating particles/droplets (anything below 100 microns) we could reliably control any variant. A simple solution that is ignored by almost everyone. Sometimes the simple solution is best.
Step 1: Make, distribute the masks
Step 2: Convince everyone they work
Step 3: Enjoy a future without Covid.
Virons are 0.07 to 0.125 microns across, and there can be lots of them in each droplet of moisture which can be 0.1 to 100 microns. 0.3 microns (and smaller) are “most penetrative particle size” (MPPS) used to certify N95 masks - they flow directly into the lungs without being trapped by mucous membranes and are the most effective vector for delivering a high dose to the lungs.
We really need more sizes of the 3M Aura 9205+ N95 - it already fits about 90% of those 12+, we just need them sized for kids and larger adults.
That is the holy grail. We could stop Covid cold. Add great ventilation in public places where we eat and we could go back to normal while science comes up with a universal vaccine.
