<p>PURPOSE:To sufficiently obtain an air amount and to improve air purifying action for removing fine particles in the air by providing a plurality of filter members in a suction port, and sequentially arranging as the members a wire netting, an insulating resin gauze, electrode pair, actived charcoal filter from the outside to the inside of a casing. CONSTITUTION:In a gas hot air room heater 1, a filter unit 40 for removing dusts such as dusts in passing air, cigarette smoke, pollen is provided in a suction port 11. In the unit 40, as a plurality of filter composing members are arranged in a unit case 41, sequentially from the outside a wire netting 42, a resin gauze 43, a positive electrode 44, a resin frame 45, a negative electrode 46 and an actived charcoal filter 47, the members are engaged with engaging grooves 41a, 41b inside the case 41, and a retaining cover 48 is engaged with the upper end of the case 41. Since the fine particles in the air to be sucked are charged, they are easily sucked when passing the actived charcoal filter, and since O3 generated at a high voltage can be absorbed, its purifying effect is improved.</p> |
