N95 dumbass. 99% of masks being worn in public are cloth or disposable, which are close to completely useless (as Fauci explained on 60 minutes in 2020). Derp!
false lol.
“The researchers reported that fabric face masks “blocked between 62.6% and 87.1% of fine particles, whereas surgical masks protected against an average of 78.2% of fine particles. N95 masks blocked 99.6% of fine particles.” But they said that survey respondents tended to “underestimate the effectiveness of masks, especially fabric masks.” The results indicated that “fabric masks may be a useful tool in the battle against the covid-19 pandemic and that increasing public awareness of the effectiveness of fabric masks may help in this endeavour,” the authors concluded.”

“Cloth masks not only effectively block most large droplets (i.e., 20-30 microns and larger)9 but they can also block the exhalation of fine droplets and particles (also often referred to as aerosols) smaller than 10 microns ;3,5which increase in number with the volume of speech10-12 and specific types of phonation.13Multi-layer cloth masks can both block up to 50-70% of these fine droplets and particles3,14 and limit the forward spread of those that are not captured.5,6,15,16 Upwards of 80% blockage has been achieved in human experiments that have measured blocking of all respiratory droplets”

Now guess what happens if both parties are wearing them? You are nearing doubling that filtration efficiency rate and reaching N95 protection levels if not higher.
you keeping up or is this math too advanced for you?
