Not correct. If you're wearing a proper mask, with the proper fit, you will, in FACT, be protected, fairly well, from viral pathogens that may be in the air, UNLESS you're right in someone's face, and they sneeze or cough directly at you.
CV19 pores are approximately 1.25 microns in diameter. N95 masks can filter out down to 3 microns, according to the last standards I read. However, for that tiny virus to penetrate a mask with pores larger than it, it needs to have force behind it and hit the surface at a perpendicular orientation. Otherwise, the many fibers in the mask should grab anything landing on its surfaces, with "should" being the operative word, here.
I worked in PPE for fifteen years. I never caught a cold, flu or any other maladies caused by airborne pathogens, from clients I worked on. I was obsessive with my precautionary measures.
With those whose pig-headed disregard for their fellow humans compels them to wander about without proper PPE, one can only hope they get what they so righteously deserve!
Save the nasty retorts: If they care not a fig about me, why should I care about them?
