Pathogen Reduction

Reduce airborne viruses through better indoor air

Through our patented technology, needlepoint bipolar ionization, also known as NPBI™, our products purify 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 mold, 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. This process is proven by independent laboratory testing to be both safe and effective.

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 bring outdoor freshness indoors.

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

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.

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.
