<p>A method and an apparatus for detoxifying harmful objects such as microbes, their toxins, and pathogenic viruses such as those of severe acute respiratory syndrome (SARS) by means of a photo-catalyst technique and an air cleaning technique so as to eliminate or minimize the damage due to such harmful objects. An air cleaner (12) incorporating air filters (16,17,19) is placed in a corner or suitably adjacent to a wall in an inner chamber (10). A dust gauging sensor (20) is mounted on or in proximity to a side wall of the air cleaner (12) to detect the amount of dust inclusive virus particles based on each airborne particle diameter circulating in a building space while a computer (23) for processing the output of the dust gauging sensor (20) is placed in an inner chamber or outside of the chamber. When the number of airborne microbe particles having a predetermined particle diameter exceeds a predetermined number in a unit of time, the air filter (17) is activated by a signal from the sensor (20) to annihilate the viruses.</p> |
