This air ionizer removes particles as small as .01 Microns. Our Air negative ionizer emits no detectable ozone so don't expect the ozone smell that ozone generators create. The Wein Vortex Negative ionizer is a true high density negative air ionizer.n one hour, the VI-2500 will remove over 98% of the most respirable particles from the air in a very large room. These are the germs or pollutant particles that can lodge deep in the lungs that the body cannot exhale.The results are ten times better than the competitive widely sold unit. A sealed safety room would continue to be almost particle free as long as the unit runs continuously.Ion output:450 trillion ions/sec cm2 at 2.5cm,Coverage:800 sq. ft. (40' x 20') room,Purified airflow output: greater than 100 feet/minute.Negative Ions are molecules that have gained an extral electron. These are beneficial to the environment because they help attract dust, cigarette smoke, pet dander, pollen, mold spores, viruses, and bacteria; thus, helping eliminate them from the air you breathe. Have you ever noticed how fresh air smells after a rainfall or near a waterfall? If so, then you have experienced ionization in its grandest form.

True high density negative air ionizer.

Shown to help treat Seasonal Affective Disorder Depression in some people.

In one hour,the VI-2500 will remove over 98% of the most respirable particles from the air in a very large room.

Particle effectiveness: as small as .01 micron and Power use: Less then 6 watts.
