Anthrax is bacterial.
Furthermore, an airborne bio attack would not use individual virus
particles (though person to person contagion would). The ideal particle
is, IIRC, around 3 to 8 microns. A mask that filtered this size would
protect you from the initial attack, which of course you wouldn't know is
coming so you should wear your mask all the time. Don't want to do that,
huh?
Personally, I like the EVAC-U8
because it protects you from smoke and fire (which a war protective mask
won't)...a far more likely event. Cheap, too.
