iWave is an air purifying device that delivers cleaner, healthier air for you and your family to enjoy.

How iWave Works

Pollutants, dust, dander, pollen, smoke and even pathogens such as mold, viruses ad bacteria all can be suspended in the air you breathe, even when you don’t see them.  An iWave air purifier installs in your air conditioning system to help clean the air in your living space.  When air passes over the iWave, ions produced by the device reduce pathogens and other airborne particles, creating a healthy environment without producing any harmful byproducts.

iWave uses patented needlepoint bipolar ionization (NPBI) technology to create equal amounts of positive and negative ions.  When these ions are injected into the air stream, they break down passing pollutants and gases into harmless compounds like oxygen, carbon dioxide, nitrogen and water vapor (see illustration below).

When the ions come in contact with viruses, bacteria or mold, they remove the hydrogen molecules – without them, the pathogens have no source of energy and will die.  The ions also attach to allergens like pollen and other particles, causing them to band together until they are large enough to be caught by your ventilation system’s air filter.  This process is proven by independent laboratory testing to be both safe and effective.

iWave’s technology generates the same ions that nature creates with lightening, waterfalls, ocean waves, etc.  Nature uses energy and shear to break apart molecules, naturally cleaning the air and producing a healthy environment.  The only difference between the iWave’s technology and nature is that the iWave does it without developing harmful ozone.

iWave Advantage

You’ll find iWave’s advanced technology provides the most effective air purification method.  Other common air purification technologies require ongoing maintenance with bulb/cell replacement every year or two, making the cost of ownership undesirable.

iWave air purifiers have no harmful byproducts, and most models require no ongoing maintenance and have no replacement parts.  In fact, with the iWave-R’s patent-pending self-cleaning design, you can enjoy years of maintenance-free performance.

Nu-Calgon offers a three-year limited warranty on iWave products.  For a valid warranty claim within three years, proof of purchase and proof of installation by a licensed HVAC or electrical contractor must be provided.  See full warranty for complete details.

The use of this technology is not intended to take the place of reasonable precautions to prevent the transmission of pathogens. It is important to comply with all applicable public health laws and guidelines issued by federal, state, and local governments and health authorities as well as official guidance published by the Centers for Disease Control and Prevention (CDC), including but not limited to social distancing, hand hygiene, cough etiquette, and the use of face masks.



What is iWave’s Needlepoint Bipolar Ionization technology?
NBPI is an artificial generation of both positive and negative ions through needle points, without the production of ozone or harmful byproducts.

How does iWave’s NPBI kill pathogens?
iWave technology produces ions that kill pathogens by robbing them of life-sustaining hydrogen. The ions also breakdown harmful VOCs into harmless compounds like O2, CO2, N2, and H2O.

Do iWave air purifiers kill COVID-19?
iWave air purifiers will kill SARS-CoV-2, the virus that causes the COVID-19 disease.  Through independent lab tests, iWave has been proven to kill 99.4% of the SARS-CoV-2 virus within 30 minutes.  When talking about pathogens, it’s important to avoid confusion and inaccuracies — use the correct terminology and call the virus SARS-CoV-2, not COVID-19.

Does iWave produce harmful byproducts?
No. Passing through an ionization field causes harmful compounds to break into harmless compounds already present in the air.

Is NPBI safe for people and animals?
NPBI products are completely safe for humans and animals. This technology only produces elements and compounds that are naturally found in air.

Do air filters need to be changed more frequently when used with iWave?
Filter change intervals may be increased in some applications based on run time and how the space is utilized. Most applications can maintain their existing filter change schedule.

Does ionization degrade filters, insulation, wire coatings, and plastic like UV lights?
No. Ionization leaves other equipment unaffected.

How long does the product last?
On average the product lasts the life of a new system, or 10-15 years.
