Results-driven technology

Through our patented technology, needlepoint bipolar ionization, also known as NPBI®, our products clean indoor air by reducing airborne particulates, odors and pathogens and energy consumption.

GPS helps deliver cleaner indoor air —producing neither harmful ozone nor other harmful by-products.

Performance Validation

Third-party certifications confirm: GPS gets the job done

Our results-driven technology fights pathogens and limits the spread of viruses.

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.

Simulation Testing

Counts of airborne pathogens are taken before and after aerosolizing them into a sealed, unoccupied laboratory environmental room installed with NPBI technology. The larger space more closely resembles a real-world environment.

Specialty Testing

This test was jointly executed with Aviation Clean Air. In this laboratory study, Aviation Clean Air designed a test to mimic ionization conditions like that of a commercial aircraft’s fuselage.

Please note that testing the reduction rate of SARS-Cov-2 with GPS’ NPBI product is an evolving process and additional testing is anticipated to be conducted in the future.
While this is not a surface disinfectant, this testing demonstrates a decrease in active virus on surfaces through particle aggregation.
