Well that was worrying. Now I'm sitting here in my air-conditioned office building wondering what the CO₂ level is and wishing I could open a window.
Got to buy a CO₂ meter: https://www.amazon.com/s?field-keywords=CO2+meter https://www.amazon.com/s?field-keywords=CO2+meter
- graeme 8y agoI think good AC is actually ok, since it's based on venting indoor air out. Definitely depends on the building though. But my CO2 meter reads lower with AC on. (With windows closed. Windows open is power still)
- janekm 8y agoIf your AC is the type that vents out indoor air then this makes sense (though smaller AC units tend to just circulate the indoor air after cooling/dehydrating). Depending on the sensor technology in your CO2 meter, it could be sensitive to temperature, so that may be worth trying to exclude as a factor.
