For others who may be curious, outdoor mean CO2 concentration is currently 410 ppm.
CO2 concentrations under 1000 ppm are described as having 'good air exchange'. CO2 between 1500-2000 is unpleasant, causes drowsiness and feels stale and gross. 5000 ppm is the typical workplace health limit.
Some guidelines are based on 1950s air quality, which had 250-350 ppm CO2. Today, you need more circulation to maintain acceptable CO2 levels than you did 50 years ago because the outdoor air has a higher concentration.
