Does the mask need to present a physical barrier to the virus particles? Is there any electrostatic force, for instance, which would trap viruses as they passe

Does the mask need to present a physical barrier to the virus particles? Is there any electrostatic force, for instance, which would trap viruses as they passed close to the mask material?
- Symmetry 6y agoYes. Also N95 filter .15 micron particles better than .3 micron particles because their motion tends to be more Brownian and less ballistic, leading to more particle/masks interactions where they can get caught.
