It was done. Other configurations are the same as those in the first embodiment.
Is almost the same as

Next, this operation will be described. Since the operation of the air supply filter 7 is substantially the same as that of the first embodiment except for the operation of the air supply filter 7, the trapping filter 7a and the nitrogen absorption filter 7b are used here. Only the operation will be described. First, when outside air (outdoor air), which is led into the air supply passage and contains nitrogen oxide gas (nitrogen oxide) and various foreign substances (such as dust and garbage) discharged from a car or the like, passes through the air supply filter 7, it is captured. Various foreign substances are captured by the filter 7a, and nitrogen oxide gas is absorbed by the nitrogen absorption filter 7b, so that clean air is supplied to the room from the indoor side outlet 2a.

As described above, when the air supply filter 7 is constituted by the trapping filter 7a and the nitrogen absorption filter 7b, the air is supplied into the room after removing nitrogen oxides and various foreign substances in the air in the air supply air passage.
