IDPH Guidelines for Indoor Air Quality | IDPH

If average carbon dioxide levels within a building are maintained at less than 800 ppm, with appropriate temperature and humidity levels, complaints about indoor air quality should be minimized. If carbon dioxide levels are greater than 1,000 ppm, complaints may occur. Therefore, 1,000 ppm should be used as a guideline for improving ventilation.

Carbon Dioxide Concentration - Comfort Levels

Since CO2 is exhaled by people at predictable levels the content of Carbon Dioxide in the indoor air can be used as a significant indication of air quality. Fresh supply air correlates to the indoor level of CO 2 as: 15 cfm ventilation rate per occupant - aprox. 1000 ppm CO2 20 cfm ventilation rate per occupant - aprox. 800 ppm CO2
