The aim of this study is to understand the characteristics of indoor air pollutants and provide information about the present Indoor Air Quality(IAQ) in 104 public facilities from January 2011 to December 2012. The measured air pollutants are PM10, HCHO(formaldehyde), CO, CO2, and total airborne bacteria(TAB). And the effects of environmental factors such as temperature, humidity and construction characteristics were analyzed in relation to the measured concentrations. The results of this study showed that the mean concentration of PM10, CO2, HCHO, CO, and TAB were 55.3 /, 558.6 ppm, 31.0 /, 1.2 ppm, and 561.3 CFU/, respectively. The correlation analysis showed that CO2 and HCHO (r=0.497, p<0.01), CO2 and TAB (r=0.468,p<0.01), and PM10 and CO (r=0.342, p<0.01) were significant. The result of regression analysis was found that the influence factors associated with the concentration of PM10, HCHO, and TAB were the year of building construction, the temperature and the humidity
