Air Purification Through Bi-Polar Ionization – How It Works

iWave devices use a patented technology called needle-point bi-polar ionization. Carbon fiber brushes produce a refined electrical charge to proactively and safely clean the air in residential and commercial buildings.

The iWave approach uses two emitters to create equal amounts of positive and negative ions. When these ions are injected into the air stream, creating a plasma region, they break down passing pollutants and gases into harmless compounds like oxygen, carbon dioxide, nitrogen and water vapor.

When the ions come in contact with viruses, bacteria or mold, they remove the hydrogen molecules from the pathogens. Without hydrogen, the pathogens have no source of energy and will die. The ions also attach to allergens, such as pollen, smoke and other particles, causing them to band together until they are large enough to be caught by filters.

iWave’s technology generates the same ions that nature creates with lightning, waterfalls, ocean waves, etc. Nature uses ion energy to break apart molecules, naturally cleaning the air and producing a healthy environment. The only difference between iWave’s technology and nature is that iWave does it without developing detectable ozone. In fact, third party testing of iWave technology by Intertek/ETL to the UL867 ozone chamber test confirmed ozone levels less than 0.00PPM!

How iWave Ionization Differs From PCO Technology

Unlike iWave’s bi-polar ionization method, Photo Catalytic Oxidation (PCO) technology uses UV light, commonly with titanium dioxide (TiO2) and often with other alloys, to create ionization.

The Centers for Disease Control (CDC) has warned of cancerous risks involved with TiO2* – not something you want in a building’s air quality! ASHRAE issued a position document in January 2015 on Filtration and Air Cleaning where they cautioned UV lamps used in many PCO devices can emit significant ozone – known to be harmful for human health. They also observed and reported on page 9 of the document “…potential of an incomplete oxidizing process, which produces by-products of reaction that can be more toxic or harmful than the original constituents (i.e. formaldehyde). The catalysts can be contaminated (poisoned) by airborne reagents and/or products of oxidation, which results in reduced or total efficiency failure of the process.”

Lastly, the PCO approach requires the replacement of the UV cell every year or two. Bi-polar ionization requires no replacement parts, and on the self-cleaning models, they are maintenance free. The chart below shows several advantages of iWave technology over two common market approaches.

Frequently Asked Questions


iWave products are patented ion-generating devices that produce the highest available ion outputs and do not create ozone or harmful byproducts, which are different than current ionizers on the market. Not only that, these are self-cleaning options that require no maintenance, no replacement parts, universal voltage and universal mounting, making these highly versatile devices game-changers in the IAQ market for proactive whole home/office purification. The devices offer a superior three-year warranty – other products require light/cell replacement in a year or two.


The ions are circulated downstream of the iWave-F, iWave-V, iWave-C and iWave-R to where they thoroughly address pathogens through the coil, duct and living space, making it an active whole purification system. This is different than UV lights with a passive approach that only address pathogens that circulate past the UV light in the duct and only affect part of the coil.


iWave products are designed to last for a very long time, up to the design life of the air conditioning equipment.
