What Is Bipolar Ionization and How Can It Affect IAQ?

Bipolar ionization sounds very cutting edge, but it’s actually proven indoor technology that has been utilized to cleanse indoor air quality in health facilities, as well as in public buildings such as hotels, airports, and other installations for many years. It’s a simple electronic system — no moving parts or maintenance requirements — and it does not require any major alterations to install in a typical HVAC system.

Normally installed inside the home’s ductwork, a compact bipolar ionization unit generates millions of positively and negatively charged ions and adds them into the airflow circulated throughout the house by the HVAC system blower. These ions are also created by nature outdoors; for example, high levels of positively and negatively charged ions are present in fresh mountain air and around fast-moving water such as waterfalls. Here’s how and why this system works:

  • Charged ions are naturally attracted to living microscopic airborne pathogens, including viruses and germs. As the ions attach to the harmful particulates, they induce an oxidation process that deactivates the virus or other living particle.
  • The bipolar ionization process also causes airborne pathogens to become attracted to each other. These particulates then clump together, making them larger and increasing the efficiency of standard HVAC air filters to remove pathogens from household air as it circulates through the system.
  • Studies by the U.S. Department of Defense have shown that bipolar ionization can remove more than 99% of harmful viruses, including SARS, influenza, MRSA, and norovirus. Most of these airborne pathogens are neutralized by the system within 30 minutes.
  • Bipolar ionization also deactivates other microscopic indoor air quality threats such as black mold spores, dust mites, mildew, and pollen.
  • In most cases, a bipolar installation sized for a residential application will consume less electricity than a 60-watt standard lightbulb.
