Questions about our technology.

What is Needlepoint Bipolar Ionization technology?

NBPI is an artificial generation of both positive and negative ions through needlepoints that treats the air in the breathing space.

How long do ions last in the air?

Typically, small ions have a life expectancy of up to 60 seconds before they touch a surface or particulate to discharge.

Do iWave or NuShield air ionizers affect SARS-CoV-2 (virus leading to COVID-19)?

iWave and NuShield Air Ionization Systems have been tested and demonstrate the ability to help reduce SARS-CoV-2, the virus that causes the COVID-19 disease. See our Performance Data for more information.

Does iWave or NuShield produce ozone?

iWave is UL 867 ozone standard certified to produce no harmful levels of ozone. NuShield is UL 2998 zero ozone emissions certified.

Will one device properly sized and installed address both coil cleanliness and assigned space ionization requirements?

Possibly. Ionization does not have a one-size-fits-all solution. Distance from the equipment to space and duct design play major roles in this equation. Contact your contractor for more information on your application.

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.

Does ionization have an odor to it?

No, ionization is odorless. Some customers have experienced a change in the way the ionized space smells due to the removal of odors they had grown accustomed to.
