Third-Party Testing

GPS works with third parties to put our NPBI™ technology to the test.

Results-driven technology

An innovative process to help 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

Advancing the science of ionization

GPS works with third-party laboratories to continually strive for best-in-class indoor air testing. Tests are conducted in large chambers designed to emulate realistic applications. To learn more about test methodology, please request test reports.

Airborne Organisms

GPS products are designed to work with air handling systems to deliver the benefits of ionization. These tests measure the reduction of certain airborne viruses and bacteria by aerosolizing a test specimen into a large biosafety test chamber (BSL2 or BSL3) and suspending it in the air using mixing fans. Measurements of the specimen are taken at regular intervals and compared to a control without the introduction of ionization.

The GPS NPBI technology was tested by Innovative BioAnalysis in a 20 foot wide by 8 foot high by 8 foot deep chamber with a temperature range between 69 degrees and 75 degrees Fahrenheit and a relative humidity range between 42% and 52%. The technology was used in conjunction with an air handling unit designed to create and sustain achievable ion density levels that have been observed in real-world applications. Mixing fans were used to disperse the ions and suspend the test specimen within the chamber. Significant variations in temperature, humidity or other environmental factors may impact performance. Testing the reduction rate of any virus or bacteria with GPS NPBI technology is an ongoing process, and additional testing will continue in the future. Tests conducted in the same manner with attention to all experimental variables should come within a margin of error of the results stated above.

Surface Organisms

GPS products are designed to work with air handling systems to deliver the benefits of ionization. These tests measure the reduction of certain viruses and bacteria on surfaces by applying a specimen to glass slides, petri dishes or coupons and placing them on a table within a large biosafety test chamber (BSL2 or BSL3). Measurements of the specimen are taken at regular intervals and compared to a control without the introduction of ionization.

Airborne Particles

GPS products are designed to work with air handling systems to deliver the benefits of ionization. These test results demonstrate the additional reduction of particles in air when NPBI is combined with mechanical filtration versus filtration alone. Particles from calibrated cigarettes were infused into a 10ft. x 10ft. x 10ft. chamber to provide a starting point consistent with wildfire smoke simulation. Testing occurred at six air changes per hour (ACH), consistent with ASHRAE guidelines.

NPBI + MERV 10 removed PM1.0 over 1.5 times faster than MERV 10 alone, the first hour after particles were introduced, based on triplicate experiments.

The GPS NPBI technology was tested by A2LA accredited [ISO 17025] Blue Heaven Technologies in a AHAM standard size testing chamber (10 ft. x 10 ft. x 10 ft.). The testing and chamber set-up follows ASHRAE 52.2 standards. The experiment design was based on industry standards and real-world scenarios. Consistent air pressure, temperature, and humidity was maintained throughout the test.

1. Removal Rate calculated as a 10-minute running average of reduction in PM1.0 per minute over the target time period. 2. PM1.0 is the mass concentration in μg/m3 of all particles with a diameter of less than 1.0 μm. 3. Measurement started after the first 15 minutes of testing to account for the high particle counts that result in unusually high average reduction in the first 15 minutes; agglomeration and surface deposition were highest during this period. 4. Ion density calculated as average of 30 minutes after reaching PM1.0 ≤ 35 μg/m3. This value was chosen as a proxy to ambient air based on EPA’s primary standard for supplemental health protection against short-term fine particle exposure which is a 24 hour outdoor average. (National Ambient Air Quality Standards (NAAQS) for PM | US EPA). 5. Product tested was the GPS-FC48-AC.
