PROBLEM TO BE SOLVED: To provide a portable air cleaner capable of supporting an air cleaning material having sufficient antibacterial activity with a simple structure, achieving stable quantitation, volatilization amount, and volatilization rate of the supported air cleaning material, having light weight, strength against external pressure, and uniform product quality, and capable of being safely used with low environmental load in disposal.SOLUTION: A portable air cleaner includes many pieces of porous solid carriers supporting an air cleaning material having volatility which are accommodated in a portable container having vent holes partially. The air cleaning material volatilizing from each of the porous solid carriers is emitted from the vent holes so as to clean the air around the container. Each of the porous solid carriers is made of a granule having a predetermined diameter, which is artificially produced from a raw material organic material, formed of approximately homogeneous substance having fine pores with approximately uniform diameter at least on the surface at a predetermined density. The air cleaning material is supported on each of the porous solid carriers such that the volatilization amount per unit time can be controlled.COPYRIGHT: (C)2015,JPO&INPIT【課題】簡単な構造で十分な抗菌作用等を有する空気清浄物質を担持でき、担持された空気清浄物質の定量化と揮散量と揮散速度が長期間にわたって安定しており、軽量であって、外圧にも強く、均質な製品の提供が可能で、安全に使用でき廃棄時の環境負荷も低い携帯型空気清浄具を提供すること。【解決手段】揮散性を有する空気清浄物質を一部に通気孔を有する携帯型の容器に担持させた多数個の多孔質固形担体を収納させ、前記各多孔質固形担体から揮散する前記担持させた空気清浄物質を前記通気孔から放出させて容器周囲の空気を清浄にする携帯型空気清浄具において、前記各多孔質固形担体が、有機物を原料として人工的に生産された所定の径を有する粒状体であるとともに少なくとも表面に略均一径を有する微細な孔が所定の密度で形成された略均質体であり、前記空気清浄物質の単位時間当たりの揮散量を調節可能に前記各多孔質固形担体に担持させた。【選択図】図1
