CO2 monitor, not CO monitor. CO is the byproduct of the combustion in your furnace, CO2 is the byproduct from YOU breathing!!!
Once you used up all the air in your room, the oxygen is replaced by CO2, and then you feel tired and dizzy.
Don't be tired and dizzy. This monitor alerts you when you run out of air. Just open the windows, and the CO2 level will drop. You'll see it on the monitor how fast that goes. Didn't your parents tell you to air out your stinky bedroom every once in a while? In fact every morning when you get out of bed?
That's right. Now you know!
