Small enough to through mask but they are attached to salvia or nasal mucus which mask will prevent.
A mask doesn't prevent anything, because it simply redirects particles to the side instead of forward.
Plus it's literally the fucking cold, who cares.
Or just cover your mouth when you sneeze or cough. Do you really cough or sneeze directly into your mask?
the pressure blows the mask off your face
zero gravity , viruses can follow the air out the sides of your nose where the masks dont seal
