PROBLEM TO BE SOLVED: To eliminate discomforting pollen, sound or troublesome wind inducing sound sleep and to simplify an air cleaner by forming an air outlet in an air bag having a porous vent portion. SOLUTION: This air cleaner comprises an air supply unit 1, having a fan 2 of an air flow generating means and a HEPA filter 3 for removing particulate substrate contained in an air flow formed of the fan 2, an air outlet 5 for supplying clean air from the unit 1, and a conduit 4 for coupling the unit 1 to the outlet 5. The outlet 5 is constituted as a flat plate shaped air bag 5'. The bag 5' is formed so as to have a plenum 5c therein by fusion bonding an outer periphery of an air permeable sheet 5a to that of an air non-permeable sheet 5b in a bag-like state. Thus, the outlet 5 can be folded and contained when it is not used, and formed into a steric shape, having the plenum 5c by diffusing the clean air from the unit 1 when used. |
