Indoor air pollution by odorants is an important problem relating to the comfort for occupants. This problem is particularly important in nursing homes for the aged. At the present time, air fresheners are commonly used as a countermeasure to reduce the concentration of airborne ammonia and methyl-mercaptane, but there has been no quantitative research related to their odorant removal performance. In previous research, the formaldehyde and VOCs removal performance of air fresheners was determined in an environmental chamber. The present study aimed at comparing the ammonia removal performance of air (fresheners using a "chamber method" and a "bag method".
