Full Report


Recent developments in the application of controllable air ionization processes have led to significant reductions in airborne microbials, neutralization of odors, and reductions of specific volatile organic compounds (VOCs) in the indoor air environment. Removal of very fine particulates (PMx) by conventional HEPA filters also is enhanced by air ionization.

The process of air ionization involves the electronically induced formation of small air ions, including superoxide O2 .-, i.e. the diatomic oxygen radical anion, which react rapidly with airborne VOC and PMx species. The significance of air ionization chemistry and its potential for contributing to significant improvements in Indoor Air Quality will be discussed using case histories.
