Effect of Adsorptive Building Material on Reducing HCHO Concentration in Room

This paper reports the effect of adsorptive building materials in reducing formaldehyde inindoor air. Although some studies have reported that adsorptive building materials are effective inreducing concentrations in chamber experiments, there are few studies which are carried out in actual room. In this paper we examine the reduction effect of changing the surface area of the adsorptive material in a room and the most effective arrangement of the material. We confirmed that the reduction effect is not always proportional to the adsorption surface area.
