The items of measurement as follow: carbon dioxide (), particle matter (), total volatile organic compounds (TVOC), formaldehyde (HCHO), total bacteria colony (TBC). Measurement site in day care center is classroom and living room where the children spent in activity and measurement time is in class. After appling technology, Two month later, it measured same mensuration. To determine which factors influence improvement indoor air quality, it analysed the measurement data by comparing before.
