The parent comment asked about the masks most people wear. I'm under the impression most people aren't wearing N95 masks, let alone N95 respirators. I refuse to wear a cloth face covering--I only wear N95 respirators with a silicone seal. I'm not taking that kind of chance.
I hate to say "right in front of your nose" because that's where the mask sits....
As others have pointed out, the reasons doctors wear surgical masks is because they prevent the spread of infection. Why do you think they are called 'surgical masks'? Why do you think doctors wear them?
The N95 standard (if you want to upgrade to a N95 mask) requires that the mask have a certain ability to filter out aerosols.
I would consider that pretty strong evidence that a (properly fitted) N95 would reduce your chance of exposure via aerosol transmission, and also reduce your ability to spread it to others via the same route.
Is this really so hard to understand?
