It is characterized in that an electric field portion is provided for the purpose of making only a mist particle size having good diffusibility . The odor floating in the indoor space can be removed by filtration (filtration) in the air purifier as in the conventional case. Then, the liquid having a deodorizing action in the liquid reservoir (a liquid in which at least one of TiO ₂ and zeolite is dispersed) is atomized by the atomizing means and sprayed by the conveying means, so that the liquid is sprayed on the indoor wall surface etc. The adsorbent ( the one in which at least one of TiO ₂ and zeolite is dispersed) is adsorbed and can be effectively removed. And by controlling the particle size of the mist atomized by the atomizing means at the discharge part and classifying it at the electric field part, the mist to be sprayed can be made only with a diffusible mist particle diameter, The odor that diffuses and adheres to the wall surface of the room can be effectively removed over a wide area. Further, since mist having a particle size with poor diffusibility is not released indoors, the indoor humidity can be kept at an appropriate humidity.
