One of the things that a lot of people don't realize is the vicious circle that happens when indoor combustion occurs.

Carbon Monoxide (CO) is created because of incomplete combustion, or better put, a lack of oxygen needed for complete combustion. Why does a lack of sufficient oxygen occur? Because the combustion sucks all of it up and turns it into Carbon Dioxide (CO2) and Carbon Monoxide (CO).

The point of all this… You don't just need to open a window to exhaust the gases produced. You need to open a window to allow fresh air into the combustion process to prevent Carbon Monoxide (CO) buildup in the first place!
