(57) [Summary] [PROBLEMS] To remove fine harmful substances such as dioxin, influenza virus, tuberculosis bacterium, etc., which have invaded household or other indoor air, and disinfect the air. SOLUTION: Indoor air is guided to an air cleaner 10 including a prefilter 15, an ionization unit 16, an electric dust collector 17 including a discharge electrode wire and an electrode plate for dust collection, and a carbon filter 18, and the prefilter 15 removes dust. And The ionization unit 16 and the discharge electrode wire ionize negatively, adsorb pathogens and harmful chemicals to the electrode plate for dust collection, and kill pathogens in fine harmful substances with negative ions and ozone generated in the electrostatic precipitator 17. Then, the air passing through the electrostatic precipitator 17 is passed through the carbon filter 18 to adsorb residual ozone and odor, and circulates to the indoor air. |
