The in-situ tests about anti-microbe of an case air filter by comparing with a control air filter under the same environmental conditions were carried out in winter 2005. Tests were performed to the filters installed in both an AHU (Air Handling Unit and OAHU (Outdoor Air Handling Unit). The main conclusions obtained from this study are as follows. (1) There were no remarkable differences in the number of adhesive bacteria and fungal between the case and control filters. (2) No differences of the number and specie of the fungi among the three kinds of culture media, i.e., PDA, M40Y, and DG-18 were observed. (3) It confirmed from the results obtained by chamber-test that many kinds of volatile organic compounds are emitted from both a case and control filter. Moreover, the quantity of the volatile organic compound emitted from a filter was not negligible.
