When these ions disperse throughout a space, such as an office or a schoolroom, they combine with particles suspended in the air. This creates a snowball effect in which particles of opposite polarities begin to cluster together, making them easier to capture in filtration systems.



During the NPBI process, contact with ions disrupts the surface proteins of certain viruses and bacteria, rendering them inactive. See our third-party testing.



GPS NPBI technology reduces odor-causing VOCs, leaving indoor air smelling fresher.

This technology has been a game-changer for our facility. We tried other products and never got these kinds of air quality results. I am constantly recommending GPS and the NPBI technology to others.

GPS Calls for Clear Guidance and Common Standards

GPS Calls for Clear Guidance and Common Standards


Helping improve indoor air is more than our business. It’s our obsession.

GPS was founded 13 years ago to deliver the clean air benefits of ionization without the negative effects produced by existing ionization technologies.

Today, GPS systems not only meet CDC, EPA and ASHRAE guidance, but GPS is leading the industry by certifying its products to the recent, more stringent UL 2998 zero ozone emissions standard*. Testing in third-party labs and feedback from thousands of installations have demonstrated the benefits and value of GPS technology and that it can play an important role — alongside other technologies, such as filtration — to deliver cleaner indoor air. Continue Reading.

It’s why NPBI technology is in more than 250,000 locations worldwide, including some of the most sensitive, closely monitored places like schools, airports, research labs and health care facilities.

GPS is an industry leader in testing and advancing ionization technology and actively embraces the call for common standards and expanded accountability on safety and efficacy. These standards will help ensure consumers can continue to depend confidently on innovative clean air technologies.

For 13 years, we’ve worked to deliver on our promise — creating new solutions to provide cleaner indoor air. Safely. Today, that effort remains our top priority.

*All GPS products comply with UL 867 or are certified to UL 2998. The current products listed on the GPS website are all certified to UL 2998.


Better Standards, Protocols and Guidance

Concerns over Indoor Air Quality call for improved standards, protocols and guidance to ensure safety, efficacy and accountability. That’s why we’re asking ASHRAE to take fair, prominent and fast action to raise the bar and ensure consumer confidence.

Having this system reduces and further mitigates the risk of pathogens from spreading inside the facilities, which is in the best interest of our veterans and employees.

GPS' patented NPBI™ technology is different from other ionization technologies - they shouldn’t be conflated or confused

Some technologies use high-voltage, produce ozone, and do not meet regulatory standards. GPS' NPBI uses a unique, lower-voltage application that helps deliver cleaner air while complying with UL’s zero ozone emissions standard.

GPS is committed to science and transparency.

We’ve invested more than $1 million in testing in the past year, have our own advanced testing centers and work with some of the country’s most trusted third-party research labs. These labs are leaders in the effort to review, refine, and confirm the safety and effectiveness of products across a range of industries.

GPS embraces the call for common standards and expanded accountability on safety and efficacy

We are eager to engage with industry partners and others to help establish common standards for responsible innovation. Together, through continued innovation, we can ensure consumers can keep depending confidently on cleaner indoor air technologies.

GPS Blog Post re: Axios Retraction

Last week, the media outlet Axios ran an article entitled “A COVID strategy backfires at schools,” which attacked GPS and our NPBI technology. Immediately following publication, our team presented evidence that the article contained false and misleading statements about the company and its technology. To Axios’ credit, after conducting an investigation and considering the evidence […]

IAQ In Schools — It’s Complicated

Indoor Air Quality – It’s Complicated Especially for Schools The waning days of summer traditionally signal the beginning of the back-to-school season.  However, after the last 18 months, the return to in-person learning is toggling between welcome and uncertain. Upon their return, administrators, teachers, staff and students will be greeted with new guidelines or protocols, […]

The Case for Universal IAQ Standards

On every side of the indoor air quality (IAQ) equation: people. At the heart of our industry: science and technology. But what’s missing today is where those two things come together–enhanced, universal standards and protocols to promote safety, validate efficacy and provide users with the confidence and peace of mind they deserve. While this is […]
