I don't know if this is the best place to ask this, but I need an extra-large respirator that would handle things like if I wanna do the various prop stuff, sanding, doing resin, maybe molding metal if I ever get down that far. But I have a bigger than average jaw and head due to having a pitutitary issue that was fixed a few years ago but has added permanent bone growth so makes doing things a bit more annoying. Any suggestions would be helpful.
