Pathogen Testing Results Executive Summary
Updated: Feb 10
GPS recently invested substantial resources for independent testing to confirm kill rates of various pathogens in a real world application using our patent pending needlepoint bipolar ionization technology. The test was designed to prove kill rates of MRSA, E.Coli, and TB, in the space, which can be found in many applications including hospitals, schools, correctional facilities, airports and many others as well.
Until recently, documented pathogen control had been limited to UV lights. It is well known that UV lights can kill airborne pathogens, but UV lights can only kill pathogens the UV light can shine on. Pathogen kill rates in systems utilizing UV lights are determined by the intensity of the UV light and the time or speed of the pathogen through the light. UV lights have several issues: first, from the time UV lights are energized, the output starts to diminish and for this reason UV lights are generally replaced annually; second, UV lights are not safe for service technicians because they can burn your skin and eyes; third, they contain mercury; fourth, UV lights will deteriorate filters, duct insulation, wiring insulation and any other type of organic material or rubber. While UV lights can work for pathogen control in recirculating systems (see Figure 2 below), they cannot actively kill pathogens in the space. In addition to not being adaptable to single pass systems without recirculation (see Figure 1 below), systems with UV lights have to rely on the ventilation effectiveness in getting the airborne pathogen back to the air handler for a chance to kill it. For the sake of argument, let’s say a UV light system kills 100% of what passes by it; if only 20% of the pathogens return to the air handler from the space, then only 20% of the actual pathogens are controlled, even with a 100% effective kill rate. This is not beneficial if you are one of the occupants subjected to the remaining 80% pathogen load in the space.
Amazing Results of GPS’ Needlepoint Ion Technology
Unlike UV light technology, GPS’ needlepoint ion technology reaches down into the space and kills pathogens at the source before they can infect healthy occupants, see Figure 1 below. Based on the recent data provided by the world renowned testing agency, EMSL Laboratories, GPS’ technology provided the following extraordinary results:
The benefits to GPS’ ion technology are:
1. Kills mold, bacteria and virus in the space
2. No replacement parts required
3. Keeps cooling coil clean when mounted on the air entering side of the coil (just like UV light would do on the air leaving side of the coil)
4. Kills pathogens in the space
5. Does not produce ozone per the UL867-2007 ozone chamber test
6. Requires essentially no maintenance in non-smoking applications
7. Shock free design
8. Fits any size system and any layout configuration
9. Little to no air pressure drop
10. Controls gases and odors in the space
11. Using the IAQ Procedure from ASHRAE 62, outside air may be reduced in most applications to 5 CFM per person or less.
