Ionization Advantage
Helping create a cleaner environment
iWave® and NuShield® bring a new, advanced air cleaning technology to the HVACR market. This patented technology, called needlepoint bipolar ionization, uses carbon fiber brushes to produce a refined electrical charge to clean the air in residential and commercial buildings. This approach produces positive and negative ions that help reduce certain viruses and bacteria. Nu-Calgon Air Ionization Systems also helps reduce particles, smoke, odors and VOCs in the air. The devices are OEM approved and can be installed in most air conditioning or heating systems.

How bipolar ionization works
Nu-Calgon Air Ionization Systems are bipolar, meaning they use two emitters to create positive and negative ions. When these ions are introduced into the air stream, they help reduce certain VOCs, pollutants and airborne gases. The emitted ions will also help reduce certain viruses and bacteria. The ions also attach to dust and other airborne particles, causing them to band together and become larger and more easily captured by the HVAC system’s air filters.
iWave’s and NuShield’s technology generates the same ions that nature creates with lightning, waterfalls, ocean waves, etc. The difference between this technology and other forms of ionization is that iWave and NuShield do it without generating unsafe levels of ozone.

How is ionization different?
Unlike bipolar ionization, Photo Catalytic Oxidation (PCO) technology uses UV light, commonly with titanium dioxide (TiO2) and often with other alloys, to create ionization.
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. Bipolar ionization requires no replacement parts, and on the self-cleaning models, they are maintenance free for the life of the device.
