But, even then, the pore size in a mask means about nothing... if the mask doesn't actually seal ? The N100 masks... do seal... so they will work "more better" than just because of the pore size ? Those stupid pleated blue paper "surgical masks"... entirely useless in protecting you from infections... and of only limited utility in limiting directional "spray"... from the one wearing the mask. They will help prevent you from spraying droplets onto others... which is why doctors wear them... so they don't infect patients during surgery... they are not using them to protect themselves from being infected by the patients ? The morons in public health... who decided that was the standard ? So that the public should wear masks that "try" to prevent them infecting others... in case they happen to find themselves performing surgery on passers by... rather than using masks that prevent themselves becoming infected if exposed to a source of transmission ? You can't fix stupid. But, N95 is not designed to be... and is not actually functional against viral threats. The VERY limited utility against viri that N95 might have... is a function of the mode of transmission... So, if transmission is by droplets... most "should be" larger than 5 microns... and N95 in a "one time use" would help. Before Covid, medical people believed, in error, that there was a "magic limit" at 5 microns... differentiating between "droplet" based transmission and "airborne" transmission of virus risks... That story is worth studying... as a case in point about the difference between medicine and science... and about how science and medicine both foster obvious errors... The 5 micron droplet size issue... which became adopted as "the standard"... came from a single study in which that number was valid... only in relation to the transmission of Tuberculosis... which is a bacterial issue ? That only got figured out just this year... that the "science" was wrong... because of a stupid extrapolation from that one, first, original study... as if that one instance ever made a lick of sense in being made a standard ? It is wildly foolish... Those of us who have been screaming "that's wrong"... for the last year and a half... have been vindicated.... but... ??? Being "right" isn't much of a reward... relative to the cost of others being wrong, yet refusing to listen... while imposing their will... in full ignorance... at ENORMOUS cost to society. Easy to generalize, from there, CORRECTLY, to "what's wrong" with the suppression of free speech... The error made included wrongly assuming that viruses would cooperate in segregating themselves into cohorts based on our incorrect beliefs about how they "should" behave... with a wholly artificial distinction being made between "airborne" and "droplet based" transmission through air... based on some fiction fostered about the 5 micron size issue. The physics of it.... was obviously absurd... In the result... among other impacts... Turns out that same stupidity is what drove our prior public health belief, in error, claiming that colds and flu are NOT airborne transmissible... which is now proven wrong. In hindsight, also perfectly obvious... that the epidemiology and the physics... AGREE... so that the experience of the transmission in the population, alone, should have been a sufficient proof that the understanding was in error. And, Covid, also... is WAY MORE transmissible by airborne means... than colds or flu... making the "social distancing" guidelines they adopted (by pulling a number out of their ass) into a bad joke...
