Envion Ionic Pro Clean Air Ionizer Compact Air Purifier with Car Ionizer 250 sq ft

The Ionic technology is totally silent. 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 joins with these pollutants, 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 Compact model is super easy to clean.
