Subsequently, large dust is removed, and fine dust is forcibly ionized by the discharge electrode 17 and the discharge counter electrode 18 in the ionizing portion 19 behind the prefilter 23 and flows in between the spaces of the rear collecting portion 1a. The dust is forcibly collected by the Coulomb force of the acceleration electrode 7a and the collecting electrode 8b, so dust particles are continuously collected at the collecting electrode 8b, and the remaining odor component is a deodorizing filter behind the collecting unit 1a. Only air that has been removed and cleaned at 24 is discharged to the outside through the discharge grill 26.

However, such a conventional air purifier can not perform any dust collecting function because the amount of dust is saturated inside the dust collecting filter after a certain time of use, so the dust collecting filter is taken out and cleaned by using water, detergent or other methods to collect the dust collecting filter. Not only can it be reused efficiently by removing dust inside, but also when it is washed with water or detergent, it takes a lot of drying time after washing, which makes it impossible to use for a long time and causes inconvenience to users.
