EFFECTIVENESS:

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, pollent, 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 polution 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 VI-2500 eliminated over 95% of these particles.  In other words, the Pentex/Wein Vortex VI-2500 Unit was 10 times more effective.

Besides previous studies elsewhere on deoderizing perfumes and chemicals, the results show that the Air Supply (BioGuard 1000) 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 2 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).

SAFETY

Ozone levels have been tested as safe by Underwriters Laboratories, USA; FUJI Testing Laboratories, Japan; University of California, Advanced Pollution Instruments, USA.

The ionizers compared in this study were:

• Pentex/Wein Vortex VI-2500

• Sharper Image Ionic Breeze Quadra Silent Air Purifier

• SILA 10-31

During this study the testing of the SILA 10-31 unit yielded the following comment:
"No air cleaning (in addition to the natural decay due to sedimentation) was detected with this unit operating during one hour.  We attribute this to the very low ion emission rate produced by the SILA unit."

The Pentex/Wein Vortex VI-2500 yeilded this comment:
"The Vortex 2500 Ionizer shows an extremely high particle removal efficiency:  it increased sharply to about 90% with 5-6 minutes, reaching about 100% within 10-12 minutes.  We attribute this high removal efficiency to the high ion emission rate of the Vortex 2500 Ionizer."
