PROBLEM TO BE SOLVED: To provide an air conditioner including a filter with better dust collection efficiency without reducing the draft resistance of the filter.SOLUTION: Charging brushes 41a, 41b are included for frictionally charging the filter 3, and a moving means is included for relatively moving the filter 3 and the charging brushes 41a, 41b in mutually contacting states. The filter 3 is rubbed with the charging brushes 41a, 41b to be frictionally charged, and dust in air is electrostatically attracted to the filter 3. |
