Product Details

Nu-Calgon iWave-R Whole House Air Cleaner - With technology installed in over 200,000 applications, iWave-R is the world's first self-cleaning, no maintenance needlepoint bi-polar ionization generator designed specifically for treating air in residential duct A/C systems.

As the air flows past the iWave-R, positive and negative ions actively purify the supply air, killing mold, bacteria and viruses in the coil and living space. The ionization process also reduces allergens,
smoke and static electricity, as well as controlling odors (cooking, pet, VOCs) and other particles in the air without creating ozone or any harmful byproducts.

How Bi-Polar Ionization Works
iWave devices are bi-polar, meaning they use 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.

Designed for universal mounting, the iWave-R can be installed inside or outside of duct, or attached magnetically near the indoor fan in the air handler. NOTE: This product may require professional installation.
