My crawlspace is outside the livingspace. The floor is made out of concrete with poured on concrete, finished with glued on PVC flooring. Aside of newly created holes it is completely sealed off, it's outside.
I did create 1 hole, where I draw my air from. This fresh air comes from 4 existing ventilation-holes, and thus it comes from outside.
You are welcome to come and have a look, from Italy it's only a day driving, I'll buy you lunch : -)
Seriously though: The air taken in is fresh, it comes from outside. I can prove that with a fryingpan, some oil and some garlic.
