For over 13 years, Global Plasma Solutions® has provided safe, cutting-edge solutions to help our customers improve indoor air quality. Recent reporting by Kaiser Health News, and subsequently picked up by others such as, and Education Week, presents an incomplete view of GPS® needlepoint bipolar ionization technology and the testing behind it.

GPS has and continues to make an unparalleled commitment to testing the safety and effectiveness of our products, and we continue to work closely with some of the nation’s most trusted scientific laboratories.

The experiences from over 250,000 installations around the world and several studies support that our unique, advanced needlepoint bipolar ionization (NPBI®) technology helps safely reduce particles and pathogens — and that it can add tremendous value and impact as part of a comprehensive, multilayered clean air system.

Not All Ionization Technology Is Created Equal

The Kaiser Health News article incorrectly portrays all electronic air cleaners, and especially ionization technologies, as producing harmful byproducts, such as ozone above acceptable limits. This is not the case with GPS.

GPS NPBI technology is vastly different from other ionization technologies in that it relies on the physics of lower-voltage applications, delivering benefits while not producing harmful ozone levels that are often associated with other electronic air cleaners. In fact, recent independent testing by Intertek Laboratories confirmed that GPS NPBI technology did not increase measured VOC byproducts.

We are also proud that our products meet UL’s stringent Environmental Claim Validation Procedure for Zero Ozone Emissions from Air Cleaners, referred to as UL 2998. This independent certification is also compliant with ASHRAE standards and follows recent EPA and CDC guidance that “the device meets UL 2998 standard certification.”

A Leader in Innovation

The Kaiser Health News article specifically highlights GPS’ use of a chamber “the size of a shoebox” during an initial test of our technology’s effectiveness against the SARS-CoV-2 virus in June 2020. This study was completed in one of the first labs in the country to offer SARS-CoV-2 testing when other major labs were unable or unwilling to conduct this testing due to pandemic protocols. To conduct important initial research on the efficacy of GPS technology in reducing SARS-CoV-2, Innovative Bioanalysis developed a small, scientific test chamber for use while it engineered proper protocols to safely perform testing in a larger, room-sized chamber.

Despite being presented with the facts, the article chooses to omit that in July 2020, as soon as the larger Bio-Safety Level 3 chamber was available, GPS began all of its testing in a larger chamber that was 20' × 8' × 8'. Efficacy results from the larger chamber were consistent with findings from the initial, smaller chamber testing. Furthermore, the latest testing from April 2021 demonstrates that GPS NPBI technology created an environment that enabled the in-air neutralization of up to 98.33% of SARS-CoV-2 pathogens in 60 minutes.

Commitment to Integrity

The data we report is fundamental to our mission at GPS. Our customers can be assured that we are committed to striving continuously for best-in-class, independent performance validation and technology research to provide both safe and effective products. We are also committed to further developing testing standards and methodologies that are relevant to real-world environments, and we remain open to working with others that share an honest commitment to improving indoor air quality.

The Kaiser Health News report states that GPS testing uses “about twice the level of ions than its leaders have publicly said the devices can deliver.” To clarify, independent testing concluded that at a concentration of 18,000 negative ions, airborne virus was reduced by 98.33% in 60 minutes in a laboratory chamber. In real-world installations, a similar ion density per cubic centimeter is achievable and maintainable with GPS technology. The ion density per cubic centimeter in any given space depends on a variety of environmental factors; however, ion densities in real-world spaces using NPBI have been observed in the range of 2,000 to over 40,000 total ions per cubic centimeter. GPS will continue to provide information to customers based on previous experiences and findings to assist them with installation and to help them determine how to best optimize ion density. Customers need to review all available data and make an informed decision concerning whether GPS products are appropriate for their desired application and environment.

GPS regularly conducts studies at various levels of ion concentration, and we remain committed to making test methodologies and results — including sensitivity testing, simulation testing, specialty testing and field testing — available to all customers and potential customers.

We stand behind our technology, our products and the important role they play in helping institutions of all types tackle indoor air quality concerns. We will continue to pursue advanced testing and standards, and we will work tirelessly to ensure that customers have the information they need to make informed decisions.
