You do realize that “open the window and hear that air” is massively energy inefficient, right?

- kccqzy 4y agoI 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)?
- mvnuweucxqokii 4y agoYou 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.
- Zanfa 4y agoHEPA 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.
- BenjiWiebe 4y agoOur house has a heat exchanger that exchanges air. So the outgoing air changes the temperature of the incoming air.
