Envion Ionic Pro Electrostatic Air Purifier 600 sq ft

The Ionic technology is ultra quiet purification. It starts by generating a stream of negative ions. The negative ions attract the positive airborne allergens and particles in the air. The negative ions join with these pullutants, then the particles are trapped on oppositely charged metal collection plates and a clean fresh flow of negative air is then circulated back into the air. The Permanent Ionic filter is easily removable and dishwasher safe. Ionic technology works silently to trap particles and pollutants while circulating clean air back into the air
