The sense of stuffiness can be due to humidity, mold, or probably just various household smells.
If your sensors are able to do remote logging, you can do your own double blind test and cover up the displays for a week and log what you feel like the CO2 level might be, and then at the end of the week compare it to the logged levels.
Either way, you might consider an air exchanger - either commercial or homemade[0] that can efficiently move air from outside to inside, without much heat loss.

- nathan-wailes 3y agoGood ideas. "Air exchanger" is another thing I'd never heard of before. And I've written down the idea to do an experiment: I think maybe what I could do is cover up my Aranet4 CO2 monitor's front screen with some tape, take it with me to different venues around where I live, write down what I think the CO2 level is at that venue, and then look at the logs afterwards.

- colanderman 3y agoI used to use this window-mounted model from PuriFresh: http://www.purifresh.com/erv.html http://www.purifresh.com/erv.html Having fresh indoor air in the winter was amazing. Unfortunately my current home has non-standard windows so it doesn't fit anywhere. If you are in the Boston area I'd be glad to gift it to you.
- nathan-wailes 3y agoWow, thank you for the tip! I'm going to look into the Purifresh, that sounds like exactly the kind of thing I'm looking for. Unfortunately I'm not in the Boston area but thank you for the offer!
