In order to compare the concentrations of the indoor air qualities according to living conditions, this thesis measured and compared the concentrations of the fine dusts before and after vacuuming, the formaldehydes of living rooms and bedrooms, and the dust mites on beds and on cotton sofas from 1st of July to 14th of September in 2009 for the total 179 households including 110 general households, 23 multi-children households and 46 low income households in Seoul and Kyung ki areas. Among them, it was 8 cases(4.5%) that the formaldehyde baseline about livingroom were exceeded, and was 26 cases(14.5%) that one about bedroom were exceeded. All of three groups presented the higher formaldehyde concentrations in bedrooms than one in living rooms. The excessive level of the formaldehyde baseline in bedroom according to the features of living conditions were higher in general households than in multi-children and low income households, and they statistically had a slight similarity(p<0.001). The excessive concentration of formaldehyde was higher in bedrooms than in living rooms, and the reasons were that the bedrooms were smaller than living rooms, the various furniture were arranged in the bedrooms’ small spaces, and the times to ventilate bedrooms were less by comparison with living rooms.
