George :
ISTR this was discussed on the shop-talk list not too long ago, you might check
the archives.
Your plan sounds good to me, except that I would want the air exit to be in the
mask, so I didn't reinhale the air I just exhaled. If your carbon mask has two
elements, you could probably just remove both, then blow air in through one of
the holes and cover the other one with a paper element.
Of course, you'll want your pump air intake outside, where it sucks only fresh
air.
