How to Use CO2 Monitors – See The Air

20210201· The CO2 level in exhaled air is about 38,000ppm. When CO2 is exhaled it is quickly mixed with the ambient air and, if the ventilation is good, the concentration is quickly reduced to safe levels. Keep the monitor away from your face, at least 3m/10ft. Preferable in a fixed point on the wall.
