Abstract
An air cleaner is described wherein an ion wind is generated by an ionizing element and directed to pass over a dust collector surface. By proper design and adjustment of the ionizing element and collector, the unit can be operated without emitting charged particles, if any, in other than the direction of orientation of the dust collector surface and thus avoiding smudging of the surrounding walls. The collector may be cylindrical in form and may be separately detachable, rendering it readily available for cleaning.
