In this paper the use of a thin adsorbent sheet composed of activated carbon particles to purify indoor air is modelled. A loose sheet with high porosity appears more effective than a dense one. The carbon sheet can be replaced by a fresh sheet after a certain period of use, thus keepilzg the volatile organic compound (VOC) level low in the remaining years. The model has been used to predict the optimal replacement time. Binary VOCs are modelled. The results turn out to be close to those from single component calculations, which suggests that the efficiency of the carbon sheet to one VOC is negligibly affeaed by the presence of other VOCs at ppb levels.
