So since @ODELL had been talking about the CO2 detectors somewhat recently I decided that I wanted to get one before my next air travel, which is next week, but I found out that when I close the door to my office, which is rather small, within an hour or so it gets above 1000! Crazy!

So now I know that in the winter, when I cant open the window, I at least need to open the door every hour or so at a minimum.

Next I am interested to see if this impacts my ability to stay focused and work efficiently in here.
