Wow, a purge, that is soo 90s. 
That is sort of dated, you may see from some of the other posts. Honestly it is much easier to clear a low volume mask, and the purge value gets to be sort of maintenance issue.. I like the atomic masks but that may not be what you are looking for.. Not sure how wide his face is but you may like the Sherwood Magnum EX they also have a purge version but I would not recommend it.
