Typical CO2 Levels at Home Test |

While this is above the 400 ppm fresh air level, it makes sense that in an occupied home or office the CO2 level should be higher than normal. If my CO2 levels at home were too high, it would mean I wasn''t getting enough fresh air. If the CO2 level was too low, it would indicate too much fresh air and wasted HVAC energy. 8

Where maximum accuracy is less important than cost, a CO2 sensor can be calibrated in fresh air. Instead of calibrating at 0 ppm CO2 (nitrogen), the sensor is calibrated at 400 ppm CO2 (outdoor air is actually between 350 ppm and 480 ppm in normal geographic locations), then 400 ppm is subtracted from the newly calculated offset value.
