    Outdoor air is ~420 ppm CO2. Unoccupied indoor spaces may be higher due to combustion sources such as gas appliances, candles and fireplaces. 

    For occupied spaces, each increase of 400ppm above unoccupied = 1% rebreathed air. 

    Cognitive function impairment increases above 1000ppm and is pronounced over 1400 ppm.1
