Abstract
An apparatus and method for establishing selected environmental characteristics in a substantially enclosed area is disclosed for removal of undesired matter therefrom while establishing selected predetermined desired environmental characteristics therein. The apparatus includes structure establishing the substantially enclosed area, the structure having units for negative ion production and positive electrostatic field establishment positioned therein. The electrostatic field establishing unit includes a field collector and pulse generating circuitry for pulsating the positive electrostatic field at a selected frequency, the field collector preferably having a collector surface which is removable and subject to processing to enable analysis of matter collected thereat. The apparatus includes controls for selectively controlling ion output, field strength, field pulsation frequency and selected functions of a fluid directing and conditioning system, and may include full spectrum lighting, structural and/or occupant grounding and/or a supplemental source of free oxygen.
