I don't know; is it more energy inefficient than having a fresh air intake via a duct? Maybe they are comparable in the absence of a heat recovery ventilation system (mentioned by a sibling comment upthread)?

You don't necessarily need to take in fresh air to freshen air in certain ways. It might suffice to pass it though a good filter.

HEPA and carbon filters do wonders for cooking smells, particulates etc, but unfortunately do nothing for the main reason you want air exchange with outside, which is CO2 buildup.

Our house has a heat exchanger that exchanges air. So the outgoing air changes the temperature of the incoming air.
