Abstract: A method for cleaning air and an air cleaner utilizing it are disclosed, by which the air cleaner can be made smaller than the conventional air cleaners when the performances are the same. According to the method of the invention, a filter formed on peripheral portion of a disk is formed along the peripheral portion of the disk so as to surround inside area of the disk is rotated, which filter is bent into wave-shape such that irregularities of the wave are formed in radial direction of the disk, thereby discharging air existing on the inside area of the disk to outside of the disk through the filter.

Abstract: A dehumidification apparatus which retains a high dehumidification ability is disclosed. The dehumidification apparatus comprises a container having at least one air inlet and at least one air outlet, and has an upper plate covering the container; a fan driven by a motor, which introduces air into the container from the air inlet and discharges air from the container through the air outlet so that air flow passing through the container is formed; and a holder for holding deliquescent dehumidification agent. The holder is contained in the container, which holder has at least one downwardly tapered compartment in which the deliquescent dehumidification agent is held. The deliquescent dehumidification agent held in the compartment contacts the air flow via through holes through which water and air can pass but the deliquescent dehumidification agent cannot pass, which through holes are formed in outer boundary of the compartment.

Abstract: A dehumidification apparatus of the type using a deliquescent agent, with which the leakage of deliquesced liquid out of the apparatus is securely prevented is disclosed. In the dehumidification apparatus, an air inlet and an air outlet are formed in the upper plate of the container. At least one closing member which can close the air inlet and the air outlet is arranged above the air inlet and the air outlet.
