Totally bogus meme. You will NEVER, EVER have a single, bare, viral particle floating around in the air.
ALL viable viral particles start out in the salt water "soup" that is the human body. When some physical process (coughing, sneezing, talking) dislodges some of that "soup", it is in the form of a small liquid drop that is far larger than a single virus particle.
That drop probably contains a number of virus particles, as well as salt, and many other dissolved body chemicals (proteins, and much else). Most of these microdrops are well within the filterable range of masks.
As the water in the aqueous microdrop evaporates, the particle STILL contains all that salt and other chemicals, so even the dried particle is far larger that a single virus entity.
Don’t confuse the idiot with facts.
