This paper presented experimental results for photocatalytic air cleaner removal performance formalodorous compounds generated from rest room. Photocatalytic oxidation (PCO) efficiency was up to 80∼90% for NH3 in chamber, 29.3% for H2S, 79.6% for CH3SH, 58.8% for DMDS individually. PCO efficiency forDMS(Dimethy Sulfide) and DMDS(Dimethyl Disulfide) were relatively lower than that of NH3 and CH3SH, thisresults indicate that DMS and DMDS removal process were effected by by-products of photocatalyticoxidation and humidity. Ozone was relatively low (below 5ppb) under the test conditions throughphotocatalytic oxidation. It is necessary to test a reliability of the air cleaner for a longtime under thevarious indoor conditions. But, prototype photocatalytic air cleaner will promise useful air cleaner for indoorair quality applications.
