CO2 Candles Experiment

CO2 Candles Experiment

In this experiment I will demonstrate how fast Carbon Dioxide CO2 rises inside a room by lighting two small candles.

I chose my study room as it can be easily isolated, plus I have got all the AQI monitors inside this room for the purpose of the experiment. The room is 7.3m². The experiment is easy, I lit 2 candles and closed the door and window of the room. Then I waiting with myself inside the room till the CO2 reached 1200ppm. Basically I logged the time when the CO2 was 430ppm and when it reached the 1200ppm with and without the candles.

With the candles the CO2 needed 35 minutes to reach the 1200ppm limit as you can see on the graph below and without any candle and with exactly the same conditions as before the CO2 needed 59 minutes to reach the upper limit.


You gain 25 minutes of more oxygen and less CO2 until the room reaches the 1200ppm limit which means more productive time and fewer headaches.
