The air containing the dust flowing through the air passage is first electrically charged to remove dust particles by the ionizer, and then maintained at a high voltage by the inflow of ionic current due to corona discharge from the discharge electrode of the ionizer. The dust contained in the air is removed by applying an electrostatic charge to a dust collecting section having a high voltage side electrode connected to the ionizer and a low voltage 11II electrode connected to the counter electrode of the ionizer. At this time, dust and moisture may adhere to the space where the high-voltage side electrode and the 1°C side electrode that constitute the dust collection section face each other, or to the mini-pleated filter installed in this space, causing the electrical resistance between the two electrodes to increase. Even if the S
Since the ionic current flowing from the discharge electrode into the high voltage side electrode constituting the garden section is always suppressed to a certain value or less due to the presence of the corona gap, an excessive current does not flow between the two electrodes.
