How It Works

Through our needlepoint bipolar ionization or NPBI® technology, we deliver clean indoor air — producing neither ozone nor other harmful byproducts.

GPS NPBI Technology

What is an ion?

An ion is a molecule or atom that is positively or negatively charged, meaning it must either gain or relinquish electrons in order to become neutral.

Cleaner Air, Naturally

Naturally occurring ions are everywhere outdoors, and they are constantly working to clean the air. Ions are created with energy from rushing water, crashing waves and even sunlight. GPS NPBI technology generates ions without producing ozone or other harmful byproducts, so you can bring outdoor freshness indoors.

A proven process to clean the air

Pollutants, dust, dander, pollen, smoke and even pathogens such as mold, viruses and bacteria all can be suspended in the air we breathe, even when you don’t see them.

Our patented needlepoint bipolar ionization technology safely creates and releases ions into the airstream using your existing HVAC system as the delivery method. When these ions disperse throughout a space, they seek out and form bonds with particles in the air through a process called agglomeration. This creates a snowball effect in which particles begin to cluster together. The larger a cluster of particles becomes, the easier it is for your system to safely filter it out of the air. This process is proven by independent laboratory testing to be both safe and effective.

Reduced Infectivity

Proven technology to fight pathogens

Contact with positive and negative ions has microbicidal effects on pathogens, which ultimately disrupts their surface proteins and renders them inactive.

*Independent laboratory studies have shown our NPBI technology limits the spread of viruses.
