It is simply a matter of particle-size capture and/or blow-by. I was told by looping the ear string it puckers the sides open so ones glasses won't fog up. One mask or Two it's still a matter of the capture of a particle and then where it goes from there once captured. It's decent policy to have something in the "active" column I suppose.
