<P>PROBLEM TO BE SOLVED: To provide an air cleaner capable of keeping contaminant absorbing efficiency, a method for controlling waster supply and drainage in order to exchange filthy water effectively and a method for controlling water supply to an impregnated part, by which a water-impregnated member can be kept in a moderately wet state when air is in contact with water and the contaminated water-impregnated member can be washed easily. <P>SOLUTION: This air cleaner is provided with a gas-liquid contacting means for decreasing a contaminant in the contaminated air by introducing the contaminated air into the water-impregnated member prepared by impregnating an air-permeable member with water and making the contaminated air pass through the water-impregnated member to contact the contaminated air with the impregnated water, a water supplying means for supplying fresh water to the gas-liquid contacting means, a draining means for discharging the contaminated water from the gas-liquid contacting means, at least one of an air sending means and an air sucking means for taking-in the contaminated air and introducing the taken contaminated air into the gas-liquid contacting means and a water supply and drainage controlling means for controlling the water supply action of the water supplying means. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
