Congratulations on your investment in Needlepoint Bipolar Ionization (NPBI™)! You’ve ensured your community is now a safer place for seniors to reside, staff to care and anyone to visit. Thank you. Not everyone in Senior Living can say that. We want to help you tell the story of your commitment to put Safety First and prevent the spread of infectious disease.

Global Plasma Solutions’ (GPS®) patented NPBI technology uses an electric charge to create a plasma field filled with a high concentration of positive and negative ions, which has been shown to be more effective than monopolar systems that emit only negative or positive ions. As these ions travel with the air stream they attach to pathogens, particles and gas molecules. The ions produced travel within the air stream into the occupied spaces of a building, cleaning the air everywhere the ions travel.
Two thorough metastudies have assessed the safety of ionization. “Air ions and respiratory function outcomes: a comprehensive review’ concludes the reviewed human experimental studies ‘do not indicate a significant detrimental effect of exposure to positive air ions on respiratory measures. Exposure to negative or positive air ions does not appear to play an appreciable role in respiratory function.” Another comprehensive review, “Negative Air Ions and Their Effects on Human Health and Air Quality Improvement’ found ‘no data showed the harmful effect of negative air ions on humans/animals.”
Moreover, in contrast to older forms of bipolar ionization, usually referred to as corona discharge systems, Needlepoint Bipolar Ionization was specifically engineered not to produce ozone. ASHRAE recommends keeping ozone levels beneath 10 ppb and warns that some ionization technologies can create ozone, which is known to be harmful. GPS has passed the extremely stringent UL 2998 certification, which requires products to not produce ozone at levels higher than 5 ppb (0.005 ppm).
To establish the effectiveness of NPBI, GPS partnered with several third-party labs, including EMSL, ALG, and Innovative Bioanalysis. Most GPS testing has been conducted at an ionization level of 1,500 ions per cubic centimeter, which is similar to what will be found in occupied spaces inside buildings where NPBI technology has been properly installed. All tests are conducted against a control group, so comparisons can be made between the natural rate of decay for any pathogen and the improvements stemming from ionization. We’re happy to share the results of any of these tests.
NPBI is an air cleaner that has some impact on surfaces, but it is not a surface disinfectant. Anyone considering installing NPBI should not be buying it with the intention of changing their surface disinfection and cleaning processes.
Global Plasma Solutions has been installing their NPBI products for over eight years. NPBI has been installed in many world-renowned institutions, including Johns Hopkins Medicine, Duke Health, Mayo Clinic, Boston Children’s Hospital, Google Headquarters, Harvard University, Starbucks Headquarters and The White House.
NPBI will improve the performance of your HVAC system by keeping coils and ductwork cleaner and free from growth. Plus, NPBI improves the effectiveness of the filters you are already using, including a four- to five-fold increase in the efficiency of a filter when challenged with viable bacteria. NPBI has been tested by a third party lab, which concluded MERV 8 filters plus GPS were as effective as MERV 13 filters at removing smoke particles.
No, you should not change your infection prevention and control processes. NPBI will enhance your current practices and make your HVAC system even more efficient at removing pathogens, plus it even makes the masks used as PPE more effective. It is important to continue to comply with all applicable public health laws and guidelines issued by federal, state, and local governments.
GPS’s lab tests prove this technology kills pathogens, but they have field tests as well:
Over the last 15 years GPS has 250,000+ satisfied installations, including many in hospitals or other healthcare settings.
You can directly measure the number of ions being emitted using a handheld monitor. You can directly measure the reduction in particles and odors using handheld monitors. For pathogens, the surveillance tracking your Infection Preventionist is already doing may allow you to see a reduction in incidents and outbreaks relative to the base rate for various infections in your buildings. Direct testing for the presence of pathogens is possible as well.
Some CMS Quality Report metrics may improve, like hospitalizations and rehospitalizations.
It’s actually cheaper than many alternatives, especially as you consider the lifetime cost of operation. NPBI requires no replacement parts, uses very little energy to run, requires virtually no maintenance (just one annual cleaning).
Currently there is no registration for IAQ equipment like this, so it is not something the EPA would be able to approve. Neither the CDC or ASHRAE currently recommend bipolar ionization (they have no official stance on it), but ASHRAE’s position document on infectious aerosols specifically says “Based on risk assessments or owner project requirements, designers of new and existing facilities could go beyond the minimum requirements of these standards […] to be even better prepared to control the dissemination of infectious aerosols.”
