  • ionic winds from the first and second rod electrodes 221 and 251 to the plate electrode 231 are formed to be opposite to each other.
  • the ionic winds blow up and down along surfaces of the plate electrode 231, thereby collecting floating dusts in the air to the plate electrode 231.
  • the collected air is discharged outwards via a flow moving up and down around a point P where an electric field is concentrated and outlets of the air may be formed on a top and a bottom of the housing 100 for such flow.
  • both surfaces of the plate electrode 231 are used to collect dusts, thereby notably improving collecting efficiency.
