A method and an apparatus for detoxifying harmful objects such as microbes, their toxins, pathogenic viruses such as those of severe acute respiratory syndrom e (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, 18 is placed in a corner or suitably adjacent to a wall in a n inner chamber (room). A dust gauging sensor 20 is mounted on or in proximity to a side wal l 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 outsid e of the chamber. When the number of airborne microbe particles having a predetermine d 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. |
