From the viewpoint of energy conservation, the number of buildings or houses which have high adiabatic characteristics or high airtight characteristics has been increasing. As a result, what we call "sick house" syndrome is also on the rise. One of the main reasons for the syndrome is formaldehyde gas evaporating from the adhesive used in block board. In this study, a high-performance chemical filter was fabricated by coating the surface of expanded plastic using polyelectrolyte thin film. The decrease in formaldehyde concentration in a closed cell was also examined for various types of chemical filters using polyelectrolytes.
