Which is Better – Bipolar Ionization or Ultraviolet Germicidal Irradiation?

By installing a Bipolar Ionization (BI) or Ultraviolet Light Germicidal Irradiation (UVGI) system within your HVAC system, you can reduce or even eliminate airborne particles such as bacteria, virus cells, mold, allergens, odors, and volatile organic compounds (VOCs).

What is Bipolar Ionization (BI) Technology?

Bipolar Ionization technology produces a natural bio-climate rich in positive and negative ions much like sunlight does in the atmosphere. The negative ions contain an extra electron while the positive ions are missing an electron resulting in an unstable condition.

To re-stabilize, these bipolar ions seek out atoms and molecules in the air to trade electrons with, effectively neutralizing particulate matter, bacteria and virus cells, odorous gases and aerosols, and VOCs.

What is Ultraviolet Germicidal Irradiation (UVGI)?

As radiation, Ultraviolet (UV) energy is a portion of the electromagnetic spectrum (a term used to describe the entire range of light in existence, from radio waves to gamma rays). UV light is invisible to the human eye.

The UV is readily absorbed by the DNA (a self-replicating material which is present in nearly all living organisms as the main constituent of chromosomes, and it is the carrier of genetic information) and RNA (which acts as a messenger carrying instructions from DNA for controlling the synthesis of proteins; although in some viruses RNA rather than DNA carries the genetic information of microorganisms).

UVGI can be used to disinfect air, liquids, and other surfaces. UVGI technology works well in HVAC applications as the air is typically blown across the lamp’s surface.
