    • Method and apparatus for accurately determining an air quality level even when the temperature and humidity are varied can be achieved. A predefining formula used for obtaining the output value of an air quality level sensor according to the conditions of temperature and humidity at a clean state is obtained, the output value at the clean state of the air quality level sensor at a temperature and humidity at air quality detection using the formula is calculated a corrected amount as a difference between the calculated output value and an output value at the clean state of the air quality level sensor at conditions of temperature and humidity providing an absolute determination reference of the air quality level is taken, and the threshold value predetermined at the conditions of temperature and humidity providing an absolute determination reference is connected, by adding the correction amount to the threshold value, and determining an air quality level by comparing an output of the air quality sensor upon the air quality detection, with the corrected threshold value.
