ABSTRACT = {PM<sub>2.5</sub> and formaldehyde are two main indoor pollutants potentially
threatening the health of human beings. In this paper, the concentrations of
PM<sub>2.5</sub> and formaldehyde inside an office were measured under different conditions. The effects of temperature on the formaldehyde originating from the decoration materials, including flooring, gypsum powder, joint mixture and
corestock, were also assessed. The results show that window ventilation can produce the same PM<sub>2.5</sub> purification as an air cleaner. The concentration of formaldehyde released from the decoration materials is highly correlated to the indoor
temperature, but it is not significantly influenced by humidity. In particular, the
percentage of formaldehyde grows approximately linearly with the increase in
the heating temperature. The importance of the different sources responsible for
the release of formaldehyde is as follows: joint mixture, gypsum powder, corestock and flooring. The concentration of released formaldehyde from the four decoration materials was found to vary from 0.08 ppm to 0.4 ppm when the heating
temperature was increased from 16°C to 30°C.},
