Removal of acetaldehyde (CH_3CHO) and ammonia (NH_3), which is the main odor components in cigarette smoke, was investigated using two different types of nonthermal plasma reactors. One is the barrier-type packed-bed plasma reactor (BPPR), the other is the barrier-type multi-layer plasma reactor (BMPR). As the experimental results using the BPPR, more than 95% of CH_3CHO removal efficiency was obtained under dry air environment. As for NH_3 removal, almost 100% removal efficiency was obtained with negligible reaction byproducts in dry air. On the other hand, approximately 90% of CH_3CHO and 100% of NH_3 removal efficiency was obtained using the BMPR with 33 W. As the experimental results of the removal of the real cigarette smoke, NH_3 was completely removed. However, removal of CH_3CHO was somewhat difficult because of its low concentration and the co-existence of other constituents.
