(Introduction) We had been measuring the odor in hospital. So the bad odor in hospital is from human. The human odor is consists of many organic substances. So we tried to make a small decompose odor substances apparatus by a titanium oxide which is a photocatalyst.We simulate human odor using alkaline ammonia, acid of the acetic acid and neutral methanol. So we measured in quantitative measurement by odor sensory test and machinary measurement.(Result) By this device is made of 21 pieces of 380 nm LEDs, and fixed fan which flow rate of 16 L/min. The methanol odor is quantitatively mesured by both odor sensory test and machinary. This measurement are exponentially reduce of odorous substances. (Conclusion) The human odor is reduced by our small device using a photochemical reaction, these odor was reduced at 63% within 20 minutes to 25 minutes quantitatively. And this curve was exponential decrease.
