Independent Testing

We put our needlepoint bipolar ionization (NPBI®) technology to the test: Third-party testing shows it helps limit the spread of pathogens.

Results-driven technology

A proven process to clean the air

The air around us is filled with particles such as dust, dander, pollen, smoke, odors and even pathogens including viruses and bacteria. Our patented NPBI technology cleans the air by introducing ions into the space via the airflow in your ventilation system. Our technology delivers indoor air that’s free of ozone and other harmful byproducts. Through NPBI️, GPS products improve the air by reducing airborne particulates, odors and pathogens.

Performance Validation

Third-party testing confirms: GPS gets the job done

Our results-driven technology reduces pathogens.

Sensitivity Testing

A petri dish containing a pathogen is placed underneath a laboratory hood, then monitored to assess the pathogen’s reactivity to NPBI over time. This controlled environment allows for comparison across different types of pathogens. Sensitivity Testing is not a measure of pathogen inactivation in the air.

Simulation Testing

Simulation testing measures in-air inactivation of pathogens. Counts of an airborne pathogen are taken before and after aerosolizing that pathogen 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. Pathogen findings occur as part of the customers’ normal course of business and are not introduced specifically for testing purposes.
