PROBLEM TO BE SOLVED: To provide a comfortable air cleaned living space by effectively removing particulate matter and/or gaseous contaminant. SOLUTION: In the living space A where air can be cleaned by irradiation 9 with solar rays 8, a double window structure 6, 14 at least a part of which is constituted of glass material and which has an inner space communicated with the living space A, is provided at a side irradiated 9 with the solar rays. A photoelectron emitter 10 and/or a photocatalyst 7 is disposed at an inner side of a constituting material of the double window. The photoelectron emitter 10 charges and removes the particulate matter 3 by the photoelectrons 11 emitted by irradiation with the solar rays and the photocatalyst 7 decomposes and removes the gaseous contaminant 2 by photocatalytic action by irradiation with the solar rays. The particulate matter and the gaseous contaminant can be simultaneously removed by disposing the photoelectron emitter together with the photocatalyst. |
