So, I have a construction N95-type mask: its vent/valve/whatever is dead center right on the front. If we're talking about droplets/aerosols mostly, it seems directionality would be a pretty big factor, so it's actually somewhat plausible that the bandana could be relatively effective despite nonexistent fit.
It seems like we could/should have had pretty reasonably authoritative information about this kind of thing from public health services by now, though.
- lowmagnet 6y agoThey both point down (actually look at the valve on the N95) is the main point, BUT the n95 is 95% filtering everywhere the valve ISN'T. The bandana is certainly not.
- jbdigriz 6y agoMany of the vented masks come with N95 inserts as they are intended to filter inhaled air of particles - originally for mountain biking in dusty climates
- cameldrv 6y agoJust put a piece of tape over the vent, and it will act like an unvented N95.

This is correct, but look closely - there is a flap valve inside the little valve housing that hinges at the top, and the direction of the exhaust is downward.
