We use a standalone supplied air respirator for work like this, expect about $700.

Or, if you have pressurised air in a appropiate quantity and quality
available out of the wall plug, you could use masks with supply from
that pressurised air. Many work safety manufacturers (like Draeger,
Auer-MSA etc.) offer such stuff. Just a special hose for the "wall
plug", pressure regulator to wear at a belt, another hose to the
mask.
