The harmfulness of HCHO and VOCs from construction material and furniture has been increased gradually. It must be need to prevent pollution materials' accumulation indoor effectively and to remove very small amount of harmful pollution materials in various plans, because these kinds of pollution materials greatly affect human body, Therefore, this study is focused to find out the improvements of Indoor Air Quality in execution of natural ventilation and bakeout to reduce indoor chemical pollution materials or not. After effects of indoor air quality by natural ventilation and bake-out being examined, it is follows the conclusion. As for the density change of TVOC and Toluene according to time lapse, in case the middle and high-story areas have bake-out, the density increased once, but it showed the gradual decrease after bake-out was stopped, and it was shown that it exceeded the standards recommended for newly built apartment. The bake-out is effective to discharge the HCHO and TVOC from the construction material and the furniture, and the natural ventilation is effective remove the indoor pollution materials.
