How iWave Works

iWave is an air purifying device that installs in any duct air conditioning system. When air passes over the iWave, ions produced by the device reduce pathogens, allergens, particles, smoke and odors in the air, creating a healthy environment without producing any harmful byproducts.

iWave uses patented technology, called needle-point bi-polar ionization, 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.

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.

iWave has proven to be the best air purifier on the market. But don’t take our word for it. See what real users are saying:

I would like to thank you so much for introducing me to the iWave air purification product. The iWave has far exceeded my expectations. In 10 days after firing up the units with the iWave installed, I have had to change the filters two times, and the third set is already showing signs of a thin cake starting to build up. The unit is effective and silent. I’ll be passing this on to our real estate clients.

I am thrilled with the change in our air quality after installing the ion generator in our residential furnace. As someone who suffers with allergies and asthma, I have seen vast improvement in my health after installation. When we moved recently, I had not re-installed the device right away and immediately noticed I had issues. However, within days of installing the device in the new furnace, most of my asthma attacks and allergy symptoms had gone away. As a licensed engineer designing all types of commercial HVAC, I can say that the energy savings in commercial applications and the health benefits of the device appear to be well worth the cost.

One of my dealers had a fire in his garage and attic. The fire department put it out fairly quickly, but for two days he and his family suffered through the smoke smell. He came in late Thursday afternoon and asked if we had anything that could alleviate the smell, and I immediately thought of the iWave-R. I showed him the video, and he purchased one.
At 7:30 the next morning, he called and said that the iWave was “amazing.” He said he and his family noticed a difference within an hour of installation, and by late evening the smell was gone. He said he will try to sell one on as many jobs as he can because he can personally vouch for them. The iWave definitely wows!

The ion generator has been installed in my building for approximately one and a half years, and I have to say the overall impact on what it accomplished was dramatic. The recovery area of my animal hospital was an enclosed area with no return air; the room was originally too warm – stagnant air to be exact, with an overpowering urine smell! After installing the ion generator, I immediately noticed a difference in the smell, and within 24 hours, the smell was completely gone.

I wanted to let you know how satisfied we are with the ion generators recently installed in our home. We live in an old frame house on the hot and humid Mississippi gulf coast that has a crawl space that seems to remain damp. My wife has always complained about the damp feel, and the mildew smell, in the house. A couple of days after the ion generators were installed, we drove our grand-daughter back to college and were gone for six days. With the house closed up for that whole time, we knew that this would be the supreme test of the ion generators. They passed with flying colors. My wife is happy; therefore, I am ecstatic!
