Abstract

An apparatus and method for selective environmental conditioning of a substantially enclosed utilization area is disclosed for removal of undesired matter therefrom while more readily establishing predetermined naturally occurring environmental characteristics therein. The apparatus includes negative ion generators and positive electrostatic field generators positioned relative to each other so that the field generators are adjacent to, and spaced a preselected distance from, the ion generators to enhance more even distribution of the positive electrostatic field and negative ions within the enclosed area and particularly adjacent to units and structural surfaces, such as walls, work surfaces, people, equipment, and the like in the area. The electrostatic field generators include field collectors and pulse generating circuitry for generating pulsations of selected frequency within the positive electrostatic field, and the apparatus includes control means for selectively controlling ion output, field strength and field pulsation frequency.
