Perceived air quality (PAQ) is defined as evaluation of indoor air satisfaction and comfortable sensory by occupants. However, there are differences between criteria of indoor pollutants and lowest sensory thresholds. In this study, we compared indoor PAQ by questionnaire with measured benzene, toluene and nitrogen dioxide (NO2) concentrations in home indoors. The NO2 concentration was the highest in Seoul, while benzene and toluene were the highest in Asan. Average PAQ score in winter was higher than that in summer. Significant correlations between PAQs of home indoor air pollution and measured pollutant concentrations were not shown and correlation coefficients (r) ranged between -0.453<r<0.258. Several groups have been divided to analyze what may affect PAQ scores such as gender, city, home indoor smoking, passive smoking, and self-reported respiratory symptoms. Gender, city, and self-reported respiratory symptoms by indoor air quality were associated with high PAQ scores by using of logistic regression analysis. We are confirmed that no association between concentrations of home indoor pollutant and PAQ scores. Therefore we further need to develop new indicator indoor air pollutants, measurement, and evaluation by PAQ.
