The present study aimed to evaluate the applicability of biofiltration to indoor air purification in a confined space for the longevity of human life and to support green activities. Currently, research on indoor air biofiltration in confined spaces is limited and ambiguous. This paper, on the other hand, provides a conceptual model that incorporates the factors to be considered while designing an indoor biofilter. The evaluation was focused on predicting the removal of certain target gaseous compounds that are generated from human bodies and from activities in confined spaces. The target gases include ethylene, ammonia, carbon monoxide, carbon dioxide, water vapor, and oxygen. A major target for the biofilter design should be the ability to completely remove ammonia gas from the confined space, due to its high generation rate (>350 mg/day/personnel) and high toxicity (over 7 mg/m3). Carbon monoxide is also a dangerous gas in that it is easily generated via incineration and is highly toxic at over 10 mg/m3; however, its removal using biofiltration is difficult.
