PROBLEM TO BE SOLVED: To provide an air purification device having a low humidification amount and furthermore having a high air deodorization function.SOLUTION: The air purification device has a body case 1 and further has in the body case 1: an air trunk 4 for connecting a suction port 2 and an air blowing port 3 air blowing means 5 for blowing air from the suction port 2 to the air blowing port 3 in the air trunk 4 a rotatable cylindrical air purification filter 6 provided in the air trunk 4 so as to block the air trunk 4 a drive part 16 for rotating the air purification filter and a water tank 7 in which a lower part of the air purification filter 6 can be immersed in water. The air purification filter 6 contains at least two fiber substrates 9 in which thickness of a fiber forming an opening 8 is different each other, one of the fiber substrates is a main fiber substrate 10 having a thick fiber for forming the opening 8, and the other is a sub fiber substrate 11 having a fiber for forming the opening 8 which is thinner than the main fiber substrate, and in the air trunk 4, the main fiber substrate 10 is arranged upstream of the sub fiber substrate 11.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】低加湿量でありつつ、高い空気脱臭性能を有する空気浄化装置を提供することを目的とする。【解決手段】本体ケース1内には、吸込口2と吹出口3を連通する空気風路4と、前記空気風路4内を前記吸込口2から前記吹出口3に向けて空気を流す送風手段5と、前記空気風路4を遮るように前記空気風路4内に設けた回転可能な筒形状の空気清浄フィルタ6と、前記空気清浄フィルタを回転させる駆動部16と、前記空気清浄フィルタ6の下部を水に浸すことのできる水槽7とを有し、前記空気清浄フィルタ6は、開口8を形成する繊維の太さが異なる少なくとも2枚の繊維基材9を含み、一方は、前記開口8を形成する繊維が太いメイン繊維基材10であり、他方は、前記開口8を形成する繊維が前記メイン繊維基材よりも細いサブ繊維基材11であり、前記空気風路4内において前記メイン繊維基材10を前記サブ繊維基材11よりも上流側に配置することを特徴とする。【選択図】図1
