I see you’re not only a vax shill, but a Karen as well.
N95 masks filter 95% of particles >3 microns in size.
Covid particle is 0.125 microns.
Do the math, genius.

Not only that, but to even approach that level of performance, they must be properly fitted (no, one size does not fit all), they are good only for a limited time and must be changed in clean-room type environments with proper procedures, and should be treated as hazardous waste when discarded (ever seen even one collection box for used masks?)
datura, the 0.125 micron is the large side. It is also measured down to 0.068 according to the CDC.
You are correct, bottom line is that the masks don’t work. An N95 might give you a few percentage points of protection. Maybe.
Good observation. The largest virus ever discovered (2) were around .75 microns and most viruses are less than .5 microns. Most of the quacks at NIH, CDC, Surgeon General and FDA drown you in a lot of word salad and misleading scientific facts. I doubt that you will see a bunch of scientists running around in N95 masks in real research facilities with dangerous pathogens.... Bio-suits and masks with independent air sources.
