Indoor air pollution is among the top five environmental health risks. Usually the best way to address this risk is to control or eliminate the sources of pollutants, and to ventilate a home with clean outdoor air. The ventilation method may, however, be limited by weather conditions or undesirable levels of contaminants contained in outdoor air. If these measures are insufficient, an air cleaning device may be useful. Air cleaning devices are intended to remove pollutants from indoor air.
Polarized-Media Electronic Air Cleaners use an active electronically-enhanced media to combine elements of both electronic air cleaners and passive mechanical filters. Most Polarized-Media Electronic Air Cleaners convert 24 volt current to safe DC voltage to establish the polarized electric field. Airborne particles become polarized as they pass through the electric field and adhere to a disposable fiber media pad. Ultra-fine particles (UFPs) that are not collected on their initial pass through the media pad are polarized and agglomerate to other particles, odor and VOC molecules and are collected on subsequent passes. The efficiency of Polarized-Media Electronic Air Cleaners increases as they load, providing high efficiency filtration with air resistance typically equal to or less than passive filters. Polarized-media technology is non-ionizing which means no Ozone is produced.
