That's the case in much of the world already... I live in area where there's tons of smog in the colder months and consider installing a system for bringing in filtered air from the outside, so that I won't have to open windows for the 6+ months smog period.

It's been my experience that the newer high efficiency buildings seem to be optimising for that rather aggressively to the detriment of breathable air, because the air in them certainly feels a lot stuffier than in the older ones I've been in. I can certainly see building owners setting the recirculation as high as they can get away with, for the lowest cost.

"Stuffy" air is your body detecting CO2. You should totally do something about it.
