Pathogen Reduction

Reduce airborne pathogens through better indoor air

Through our patented technology, needlepoint bipolar ionization, also known as NPBI®, our products help improve indoor air by reducing airborne particulates, odors and pathogens — all while saving you energy consumption and lowering your carbon footprint.

GPS delivers clean indoor air without producing ozone or other harmful byproducts.

*DISCLAIMER: Global Plasma Solutions (GPS) uses multiple data points to formulate performance validation statements. GPS technology is used in a wide range of applications across diverse environmental conditions. Since locations will vary, clients should evaluate their individual application and environmental conditions when making an assessment regarding the technology’s potential benefits.

The use of this technology is not intended to take the place of reasonable precautions to prevent the transmission of pathogens. It is important to comply with all applicable public health laws and guidelines issued by federal, state, and local governments and health authorities as well as official guidance published by the Centers for Disease Control and Prevention (CDC), including but not limited to social distancing, hand hygiene, cough etiquette, and the use of face masks.

Pathogen Reduction 50 50

A proven process to clean the air

Pollutants, dust, dander, pollen, smoke and even pathogens such as viruses and bacteria all can be suspended in the air we breathe, even when you don’t see them.

Our patented needlepoint bipolar ionization technology safely creates and releases ions into the airstream using your existing HVAC system as the delivery method. 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 safely filter it out of the air.

Reduced infectivity of certain viruses by >90%

Contact with positive and negative ions have microbicidal effects on pathogens, which ultimately disrupts their surface proteins and renders them inactive.

Cleaner air, naturally

Naturally occurring ions are everywhere in the outdoors, and they are constantly working to clean the air. Ions are created with energy from rushing water, crashing waves and even sunlight. GPS NPBI technology generates ions without producing ozone or other harmful byproducts, so you can freshen the air indoors.

Performance Validation

Third-party testing shows: GPS gets the job done

Our results-driven technology reduces pathogens and particles.

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 installed with NPBI technology.

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.
