Abstract
An air cleaner has a discharge electrode member, an intermediate electrode member, and a counter electrode member disposed opposed and spaced apart from each other. A voltage source is connected between the discharge member and the intermediate member for generating ionic wind. A further voltage source is connected between the intermediate member and the counter member for accelerating the ionic wind such that the gradient direction of the electric field between the discharge member and the intermediate member is identical to that between the intermediate member and the counter member.
