There were some half-asses, lukewarm admissions sometime in the last year where they sort of, kind of, admitted that most masks did absolute jack shit, save for N95 (because N95 has electrostatic charge that "might" do something, in spite of how tiny the Covid virus is).
But of course, that's purely at the hypothetical level, since these fuckers don't ever follow through with actually proving a damn thing with anything even resembling solid evidence. And that electrostatic charge is generally not reliable at all upon repeated use of a mask.
