Get a pressure hood instead of a mask. Positive pressure inside the mask
keeps out unwanted gasses and particulate matter.

Is the issue here fumes or simply not wanting to inhale dust?

Depends on what the OP is blasting on a small scale, but in industry
you wear a full hood even if it's just blasting paint off a bridge.
I'm not sure if that is a Michigan MIOSHA or OSHA reg.
