Yeah if you live in a place with pollution outdoors and no indoor HVAC there is a real severe trade off between co2 and aqi If a place is sub say 70-100 in AQI

If a place is sub say 70-100 in AQI then usually indoors will be 4-13 AQI with windows open but above that you’ll see indoor increases with open windows.
- dzhiurgis 4y agoCold climates also suck for co2. There are very cheap hrv’s but I think they are noisy.
- graeme 4y agoThat one’s actually easier. Air circulates much better when there is a temperature difference. A single window opened a crack will generally ventilate most homes or apartments. There will be somewhat higher heating costs but usually not excessive. Less than a lot of non-essential things people already spend money on
- graeme 4y agoTo manage high AQI and high CO2 and you need the windows open enough to ventilate and enough hepa to lower the AQI pollutants that comes in
