VII. PRACTICAL INSTALLATION AND TESTING RESULTS: The collected results of UVC LED sterilizing fan, the process is carried out in an intensive care unit. In the first 30 minutes, the result showed that the volume of bacteria in the air reduced from 219CFU/m3 to 116CFU/m3. In 50 minutes, the volume continued to decrease from 116CFU/m3 to 9CFU/m3, and only 9CFU/m3 left in 70 minutes. The sterilizing rate reaches to 95.89%. If the testing process was continued longer, a tendency discribed as below:
