Regular filter resperators, the kind that cost 15 bucks, have one-way valves
in them to inhale through the filter and exhale directly. You test the
valves and the mask seal by blanking the inlet and inhaling, then blanking
the outlet and exhaling. If you were to hook your supply hose to the inlet
of such a mask, you would get a jump on the technology needed without having
to fabricate stuff.

No. Seal up the second inlet. Let the regular exhale valve do its work.
