Remediation effect of indoor airborne fungi by operating the ionizing air cleaner in the university office.

Our study from Feburary to March, 2003, were done in university office A and B, located in Seoul. This study was carried out to investigate the reduction of the airborne fungi before and after we activate the air cleaner which using ionization. And the method of assessment was done by the CAMNEA method. The result was as follows. 1. In the research office A, the concentration of the airborne fungi was 18(${\pm}$11.3) CFU/㎥ before the ionizing air cleaner system was turned on: whereas three days after this result the concentration decreased to less than 1 CFU/㎥. 2. In the laboratory office B, the concentration was 210.6(${\pm}$5.3) CFU/㎥ before using the air cleaner and was decreased to 32.2(t 10.3) CFU/㎥ after using the air cleaner. The remediation rate in the experiment was 85 percentile,
