Bipolar ionization (BPI) is an indoor air quality method where air cleaners are installed within HVAC systems to create reactive ions or reactive oxygen species (ROS) in the air. These ions react with airborne contaminants, such as viruses, and clump together, where they are removed from the air via an electrostatic force.
With very little impact to the existing HVAC system, you can have a unit that proactively cleans the air by killing 99 percent of viruses, bacteria, mold, smoke and VOCs — with virtually no maintenance needed.
Mike Lee, president, Northern Weathermakers HVAC, Inc., Northbrook, Ill., says he was leery of using any type of ionization product due to concerns over ozone generation, which is an irritant to humans.” Based on third party research, air purification does not create ozone or any harmful byproducts. Lee says, independent studies show that air purification works against the COVID virus. Bipolar ionization generator is specially designed for light commercial systems up to 12 tons with no maintenance or replacement parts needed. It can be duct-mounted indoors or outdoors, depending on the application.
