EVALUATION OF IONIC AIR PURIFIERS FOR REDUCING THE AEROSOL CONCENTRATION AND INACTIVATING  VIABLE AIRBORNE BACTERIA IN THE BREATHING ZONE

A year long study by eminent researchers in air pollution science has concluded that Pentex/Wein ionic air cleaners can substantially prevent the inhalation of toxic particles such as smoke, dust, pollens, molds, many allergens, fungi, germs and the most dangerous particles that would otherwise remain trapped in the lungs.

This study was performed by leading authorities in air pollution research in laboratories that have no equal in this country that are used by EPA, NIH, OSHA, CDC, NIOSH, HUD, NIST, and NATO.

Wearable and stationary ionic air cleaners from three different manufacturers were evaluated and the results and conclusions reviewed by experts . The Pentex/Wein ionic air cleaners surpassed the other manufacturers by a wide margin. Indeed, in one study of a competitor's room unit versus the Pentex/Wein Vortex VI-2500, 50% of the most dangerous particles still remained airborne and breathable while the Vortex VI-2500 eliminated over 95% of these particles. In other words, the Pentex/Wein VI-2500 Unit was 10 times more effective.

Besides previous studies elsewhere on deodorizing perfumes and chemicals, the results show that the BioGuard from Pentex/Wein Products Inc. prevents more than 85% of dangerous pollutants from being inhaled and that close to 75% of many germs are killed within two seconds of entering the human breathing zone.

These studies confirm previous studies by UCLA, The Good Housekeeping Institute, Fuji Testing Laboratories and MIE Corp. (Monitoring Instruments For The Environment)

The Authors of this report conclude:

"The research teams at the Department of Environmental Health at the University of Cincinnati Medical Center are very excited about these studies and are now considering two papers to be prepared and submitted to major peer-reviewed journals with international circulation."

The researchers will present the report to the annual European Aerosol Conference at Leipzig University, Germany.
