The present invention provides a wet-type air cleaner comprising: an air pressure generation unit a fluid supply unit and an air purification unit. The air pressure generation unit comprises: a first housing which has a blowhole at an upper end thereof and a blower fan which is installed inside the first housing to draw in the outside air to supply the same to the blowhole. The fluid supply unit comprises: a second housing which has an open upper part, and is joined to an upper side of the first housing a transfer pipe which is installed inside the second housing, and has open upper part and lower part to communicate with the blowhole and a water vapor supply container which forms, inside the transfer pipe, a first water storage space with an open top to supply water vapors. The air purification unit comprises a third housing, a first guide pipe, a second guide pipe, a disc assembly, and a cover, wherein the third housing has an insertion hole in the center of an upper end thereof, has an air outlet on an upper circumferential surface thereof, and is joined to an upper part of the second housing the first guide pipe is seated in the center inside the third housing to form a first fluid path with open upper and lower sides to vertically communicate with the water vapor supply container the second guide pipe is inserted through the insertion hole to form a second fluid path with open upper and lower sides between the third housing and the first guide pipe a disc assembly is slidably inserted between the first guide pipe and the second guide pipe, and includes a plurality of inclined plates for turning fluids downwardly and the cover covers the insertion hole of the third housing. Accordingly, the fluid paths are configured to enhance the retention time for which the introduced air is in contact with water vapors and the contact area thereof, and to minimize flow resistance, and thus air purification effects are improved.COPYRIGHT KIPO 2018본 발명에 따르면, 상단에 송풍구가 마련된 제1하우징
