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.

Inspired by Nature

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 freshen the air indoors.

How It works teaser 2x

A proven process to help clean the air

Particles like dust, dander, smoke and even 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 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 filter it out of the air.
