Seoul Metro is currently operating by installing the PSD at all station of the 1~4 line. After installation of the PSD, the safety of passengers was ensured, but Because supply and exhaust for air of platform is not normal, the discharge of polluted air was not enough.. The full renovation of the station is needed by deterioration, but it is not easy by nature of large-scale public transportation operated daily. If you do not secure adequate ventilation to the underground station, it leads to deterioration of the health and comfort of passengers by air quality worse. This paper studies solution plans for the deterioration of air quality inside station that PSD is installed.
