ぬ弊害を招くことがある。 BACKGROUND ART Conventionally, air cleaners having an electrostatic precipitator to remove dust and smoke from the air, and air cleaners having an activated carbon filter to remove organic compounds from the air have been known. However, activated carbon filters cannot remove carbon dioxide gas from the air, so in buildings where the density of residents is relatively high, such as offices, coffee shops, bars, theaters, movie theaters, restaurants, etc., and indoor temperature control is not possible. Therefore, in spaces where ventilation is restricted, the concentration of carbon dioxide gas gradually increases, while the concentration of oxygen gradually decreases, which can lead to unexpected problems such as a decline in the work efficiency of brain workers.
