We are here to help answer your customer service or product questions.

How do I select the right product?

A representative will conduct a site survey and customer interview to help determine the right product to fit your needs in terms of coil cleaning, particle reduction and/or pathogen control.

How does this product save energy?

Outdoor air is required to ventilate a property according to the VRP (Ventilation Rate Procedure), which requires HVAC equipment and HP. By increasing the indoor air quality and minimizing contaminants of concern, a site may be able to reduce the need for outdoor air by up to 75%, which could save on upfront HVAC capital costs and yield less energy consumption. (Reference the Indoor Air Quality Procedure IAQP in ASHRAE 62.1)

Do we earn LEED points with the installation of this product?

There are two ways our products help contribute to generating LEED points, in accordance to the U.S. Green Building Council. As a part of the LEED “Indoor Air Quality Assessment,” a site must demonstrate that certain contaminants do not exceed specified concentration levels, using baseline IAQ testing protocols. Our products enhance indoor air quality performance to help achieve the desired levels. And as a part of the LEED “Optimize Energy Performance,” a site can also earn points by analyzing efficiency measures focused on load reduction and HVAC-related strategies. Our products can help demonstrate the potential energy savings and cost implications for all affected systems.

What is the warranty on GPS products?

Equipment manufactured by Global Plasma Solutions Inc. is warranted by GPS to be free from defects in workmanship or materials for a period of one year from the date of shipment to the original customer.

Is NPBI safe for people and animals?

GPS NPBI (needlepoint bipolar ionization) products are completely safe for humans and animals. With over 250,000 installations and many testimonials, GPS products have not only proven to be safe, but they also make the air cleaner and safer. GPS technology produces what naturally occurs in nature, and since GPS technology has been certified by UL 2998 as ozone-free, there are no health concerns.

Is your product UL certified?

Yes. Our NPBI technology has been certified by UL 867 and UL 2998 to be ozone-free. Also, RTCA DO-160 for aircraft.

What happens if you touch the brushes?

Touching the emitter brushes will produce a mild to moderate electric shock. It is not recommended.

Will ionization burn your eyes like UV will if you look at it?


How long do the ions last in the air?

Typically, small ions have a life expectancy of up to 60 seconds before they touch a surface or particle to discharge.

What is the optimal ion count in a space?

About 2,000 ions/cc/sec.

How does NPBI technology compare to UV technology for improving indoor air quality?

A UV light’s intensity will fade over time, reducing its effectiveness. The auto-cleaning technology employed by GPS ensures ongoing optimal performance. UV lights require costly bulb replacement at regular intervals. GPS does not require periodic replacement parts.

Does this replace UV technology or work in conjunction with UV technology?

NPBI is an ozone-free alternative to UV light, but it is possible to use NPBI and UV light in combination.

How do I know the product is working?

Check the indicator lights on the DM48, FC48, iRIB and iMOD Power Supply (not module), call the installer or purchase one of our sensors.

Does the technology generate line noise or EMF?

GPS technology does not generate line noise and does not generate electromagnetic forces. GPS technology is the only ionization technology approved by the FAA for installation on aircraft, since it’s passed the stringent DO-160 certification. This certification proves there is no line noise and no EMF (which can be detrimental to aircraft avionics, if produced).

Will one product properly sized and installed enable me to address both coil cleanliness and assigned space ionization requirements?

Possibly. Ionization does not have a one-size-fits-all solution. Distance from the equipment to space and duct design play major roles in this equation. Contact GPS for more information on your application.

Are there byproducts?

No. Passing through an ionization field causes compounds to break into one or more of four basic elements: oxygen, nitrogen, carbon dioxide or water vapor.

Can you measure how the product is performing?

GPS offers iMEASURE™ and iDETECT™ sensors to measure product performance.

Does NPBI mitigate the need for carbon filters or HEPA filters?

GPS recommends using filters in conjunction with NPBI.

Do air filters need to be changed more frequently when used with NPBI?

Filter change intervals may be increased in some applications based on run time and how the space is utilized. Most applications can maintain their existing filter change schedule.

Does ionization degrade filters, insulation or wire coatings?


Does ionization have an odor to it?

No, ionization is odorless. Some customers have experienced a change in the way the ionized space smells due to the removal of odors they had grown accustomed to.

Does NPBI mitigate ALL odors that carbon filters capture?

NPBI will mitigate odors created by compounds with an electron volt potential of 12EV or less.

Can both coil cleanliness and ionization requirements be met with a single product?

The iRIB and iMOD models are good options for this, as can be the FC48 (based on mounting location).

What are the auto-cleaning settings?

The factory setting is to clean once every three days. The cleaning frequency can be changed to clean between once every day to once every five days.

Will humidity affect the NPBI ion output?

Humidity does not impact the ionization output; however, if water condenses on the needle tips, ions cannot emit and the ion output will be greatly reduced or cease.

How long does it take to install?

Typical installations can be completed in 30 to 60 minutes per system.

Does GPS install the product?

No. Please contact a trained professional in your local area for installation.

Do I have to clean the product unit?

Models FC48-AC, FC24-AC and DM48-AC feature an auto-cleaning, maintenance-free system for easy use and ultimate convenience. These models include a programmable auto-cleaning cycle that cleans the carbon fiber brush emitters on your desired schedule. Under most circumstances, the factory auto-clean setting for every three days is sufficient.

How long does the product last?

On average, our products last 7–10 years. Accelerated life cycle testing has shown the emitter brushes and the motor that actuates the arm that cleans them last more than 20 years.

Are replacement parts available?

Yes, GPS offers replacement parts.

Are any aftermarket consumables required?

GPS recommends NPBI be used in combination with air filters.

Does product performance deteriorate over time?

Auto-clean models retain the highest levels of performance over time. To avoid degradation in performance, models without auto-clean should be cleaned once a year in most applications and every six months in high-load situations.

Does the product keep my HVAC ducts clean, eliminating the need for annual or periodic cleaning?

Customers who have installed GPS technology have greatly reduced or eliminated the need for duct cleaning.

What special tools are required for troubleshooting?

A high-voltage probe attached to a digital multimeter and a handheld ion counter are needed.

Can I install it myself?

GPS recommends installation by a trained professional.

What is the electrical consumption of the product?

The electrical consumption is up to 15 watts or less per unit.

How long does it take to install?

Typical installations can be completed in 30 to 60 minutes per system.

Does GPS install the product?

No. Please contact a trained professional in your local area for installation.

Where do I install the product?

Our products were designed for flexibility with mounting, offering multiple mounting options including at the fan inlet, interior duct wall or interior duct floor. The best mounting location is after a prefilter and before the cooling coil. If this location is not possible, the device may be mounted after the cooling coil. As a last resort, the device can be mounted before a filter, but the filter will stop the ions and there will be no further benefit downstream of the filter.

Is the product easy to install?

We designed our products to be easy to install across many environments and conditions. Our products offer multiple mounting options including at the fan inlet, interior duct walls or interior duct floor. The all-composite and carbon fiber construction allows the product to be mounted in corrosive environments.

Are any special tools required for commissioning?

For a typical installation, no special tools are required.

Can it be connected to a BAS system?

Yes. Our products can be used with a building automation system (BAS).
