Please be cautious with this airline respirator?approach as well. There must be an in-line CO detector to safely use "wall plug" compressed air. An affordable alternative might be a Survivair-type inexpensive supplied air unit. In all cases, though, the flammability must also be considered and may require ventilation.

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.
