Third-Party Testing

In the lab and in the field, GPS works with third parties to put our NPBI™ technology to the test.

Results-driven technology

A proven process to clean the air

The air around us is filled with particles such as dust, dander, smoke, odors and even viruses and bacteria. Our patented NPBI technology helps reduce particles in the air by introducing ions into the space via the airflow in your ventilation system. 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. In addition to this clustering effect, contact with ions also inactivates certain viruses and bacteria.

Performance Validation

Third-party testing confirms: GPS gets the job done

Our results-driven technology reduces certain viruses and bacteria.

Sensitivity Testing

A petri dish containing a virus or bacteria is placed underneath a laboratory hood, then monitored to assess its reactivity to NPBI over time. This controlled environment allows for comparison across different types of viruses and bacteria. Sensitivity Testing is not a measure of inactivation in the air.

Simulation Testing

Simulation testing measures in-air inactivation of viruses and bacteria. Counts of an airborne virus or bacteria are taken before and after aerosolizing it into a sealed, unoccupied laboratory environmental room

Specialty Testing

Unoccupied laboratory test environments are designed to evaluate NPBI performance in conditions unique to particular industries or customers and may include special circumstances such as higher-than-average ion concentrations. Review individual test results for details.

Please note that testing the reduction rate of SARS-Cov-2 with the GPS NPBI product is an evolving process and additional testing is anticipated to be conducted in the future. GPS NPBI products are not marketed as, nor cleared by the FDA as a medical device.

Field Testing

Measurement at actual customer locations can be compared in rooms with and without NPBI or the same room before versus after NPBI. Measurement variables and test criteria are determined by the customer. Virus and bacteria findings occur as part of the customers’ normal course of business and are not introduced specifically for testing purposes.

Zero Ozone Emissions

GPS has earned UL’s stringent Zero Ozone Emissions Certification across its entire product line.

UL is the global safety science leader that provides testing, inspection and certification, including ozone safety standards that help people make informed choices when selecting systems.

All current GPS products* are certified to UL 2998 not to introduce more than five parts per billion of ozone - which is considered the threshold for zero ozone emissions.

For more information and to view our certified products, visit the UL SPOT website.

*Prior models may be either UL2998 certified or UL867 compliant.
