Rids the air of most dust particles - Charged particles are attracted to each other and are taken out of the breathing range. Since bi-polar ionization will go the source of contamination, a larger percentage of particles are affected than with filter systems. * Chemical pollution reduction - Chemical off-gasses (Volatile Organic Compounds - VOCs) and odors are eliminated by the interaction with ionized air, eliminating the use of masking agents that add to indoor pollution. * Microbials Reduction - Airborne molds, bacteria and viruses are reduced by particle decay as well as by ionized air disturbing their reproductive cycle. The ions act as hydroxyl radicals - they remove hydrogen from the outer shells of mold, and the surface proteins of a virus. They also inhibit the receptors of allergens from causing allergic reactions, even if you may breathe them in. * Static Reduction - Static electricity is neutralized. Where humidification is needed to compensate for excessive dryness, static can be reduced or eliminated. Visible dust is also reduced, as its static cling is eliminated, and less labor is needed for cleaning.
