>Normally a high CO2 level will go hand in hand with the air feeling stuffy I bought my Dad a NetAtmo weather station one part is outside and one is inside. During Christmas with guests over I looked and saw the CO2 was 1000ppm it felt very stuffy (no air handler in an old house). I opened a window and let some fresh cool air in and CO2 out. It felt so much better. It was nice to know why it felt stuffy. It wasn't just all the turkey and potatoes that I had eaten.
