IMPROVED FILTER MEDIA FOR ACTIVE FIELD POLARIZED MEDIA AIR CLEANER

摘要

The filter media for the active field media air purifier comprises two layers of dielectric material having a high resistance air permeable screen sandwiched between low resistance electrical layers. The filter media further comprises a blended fiber filter layer having fibers from different sides of the triboelectric scale. The filter media may further comprise a layer of relatively high density dielectric material following a layer of relatively low density dielectric material.
