You can get a hepa filter mask from places like Airgas.
THese were designed to be used by coal miners, and filter out almost all of the dust, etc. (but not isocyanates from modern auto paint).
I think the combo of black beauty and a hepa mask is a winner for blasting. That is what I do, courtesy of Paul's orginal post years ago.
