I’m fully on board with “N95s work” but I still think this information is near useless from a public health point of view. They need to be fitted properly, which among other things, means being clean shaven. If you thought mask mandates were political trouble, just wait for the shaving mandate.
N95 masks still work (substantially reduce spread when worn by index patient and/or their contacts) when not fitted carefully. They then don’t live up to their rated specification, but are still a whole lot better than nothing or a lower-filtration mask.
