1/ "Masks reduce transmission risk by decreasing the quantity and velocity of respiratory emissions and increasing their dispersion. They do not eliminate trans- mission risk, however, because pathogen-laden aerosols can enter or exit the gaps between masks and faces"
2/ Again-- why *fit* is so critically important
The fit on N95 masks is better than ear loop masks. The latter can be augmented using mask braces @FixTheMask
In the hospital, we undergo fit testing for N95. Can approximate this in the community too

3/ Not completely fool-proof but one quick measure could be to check on how much glasses are fogging as a very general estimate of how much you are exhaling (& potentially inhaling)
In hospital, I use this to re-adjust my own fit as well

4/ Important to remember mainly for men- facial hairs can disrupt the fit so please be cognizant of this
Moreover, face shape does play a role in the size of the mask that will fit you best! If it feels like its too loose, it probably is
