Brand new in box. Quietly cleanse the air in any room with the Vortex VI-3500 Ionic Air Purifier. The VI-3500 begins to work immediately once plugged in, alternating between "on" and "off" cycles. When on, a stream of 3.4 trillion ions per second is released into the air. The air purifier is engineered to release them in a vortex pattern that simulates the natural airflow of a room. The negatively charged ions then bind to the positive ions in the dust, mold spores, pollen, smoke, viruses, bacteria, fumes, odors, and allergens. Once in the "off" cycle, these bound particles fall to the purifier's foam collector pad or harmlessly to the floor, to be removed when you next vacuum.
