What is the physical explanation behind this fact, and how come normal masks protect others if a carrier wears it?
- TomMarius 6y agoThe physical explanation is simple, the gaps between the strings of the mask are significantly wider than 50-100 nm. The mask protects others through preventing you from breathing/coughing on them, which it does way better than preventing you from breathing contaminated particles in.
- P-ala-din 6y agoso you're saying that the gaps are so wide that almost no contaminated particle (getting in) will get stuck on the mask? but somehow (some of the) particles going out will get stuck. how is that simple?
