Odor control from living environment has become of increased concern. In a previous paper, we investigated the removal of acetaldehyde (CH3CHO), which is one of the main odor components in cigarette smoke using the barrier-type packed-bed plasma reactor. In the present paper, we reported on the new results of acetaldehyde and ammonia (NH3) which is another odor component of cigarette smoke. In the experiment, two kinds of AC nonthermal plasma reactor were used. One is the packed-bed plasma reactor used in the previous paper, the other is the film-type plasma reactor consisting of laminated parallel aluminum plate electrodes. This reactor has lower pressure drop and higher energy efficiency than the packed-bed plasma reactor. In the experimental results using the packed-bed plasma reactor, more than 95% of acetaldehyde removal efficiency was obtained under dry air and N2 environment. As for NH3 removal, almost 100% removal efficiency was obtained with minimum reaction byproduct under dry air environment. In the experimental results using the film-type plasma reactor, it was confirmed that more than 90% of acetaldehyde removal efficiency could be obtained when the applied voltage is 8 kV (SED=391 J/L). The by-products were quantified using an FTIR. The induced HNO3 reacted with NH3 to produce NH4NO3 aerosol. In treatment of cigarette smoke, one of the main odor components NH3 can be completely removed. However, complete removal of another main odor component CH3CHO was somewhat difficult because of its low concentration
