The paper discusses full-scale residential building tests to determine the effects of building features on indoor air and pollutant movement. It was found that the activated heating and air-conditioning (HAC) system served as a conductor that enhanced the indoor air movement and transported the pollutants from their sources to the rest of the house. The interior door functioned either as a barrier or as a channel for the air exchange between the room and the rest of the house. The outside window brought about leaks. The area exhaust fan was a very effective pollutant remover when properly used. It is recommended that either an outside window or an exhaust fan be installed in rooms where indoor pollutants may occur. If indoor air pollutants are accidentally released, it is recommended that the source be isolated by closing the door of the room and turning off the HAC system. Outside windows should be open and the area exhaust fan in the polluted room should be kept on for several hours to completely dissipate the indoor air pollutants.
