"On October 26, I took 2 airborne mold samples within the property in order to determine how many airborne spores were present. I used an air pump and drew 75 liters of air through an special filter which captures
airborne mold. The lab report results show that there were: - 335,518 total airborne mold spores per cubic meter in the main room of the basement. - 356,912 total airborne mold spores per cubic meter in the back bedroom of the basement. The predominant species that were captured are chaetomium, cladosporium, aspergillus and penicillium. The airborne samples included several other mold species but they were in much lower levels. On November 10, I took 2 airborne mold samples in the same places with the same air volumes and sent them to the same lab for consistent comparison analysis. The lab report results show that there were: - 9,212 total airborne mold spores per cubic meter in the main room of the basement. - 2,667 total airborne mold spores per cubic meter in the back bedroom of the basement. The predominant species that were captured are chaetomium, cladosporium, aspergillus and penicillium. The airborne samples included several other mold species but they are in much lower levels. Therefore, the total airborne mold spores per cubic meter in the main room of the basement were reduced by 97.5% and, the total airborne mold spores per cubic meter in the back bedroom of the basement were reduced by 99.5%."

E. coli Reduction
MRSA Reduction
M. terrae (TB) Reduction
Mycobacterium terrae (M. terrae) is commonly used as a surrogate test for
Mycobacterium turberculosis as it demonstrates similar physical characteristics and is slightly more resistant but is far less dangerous. EMSL Analytical, Inc.

Ozone TestGPS Excels During UL 867 Ozone Testing
GPS is pleased to announce that our needlepoint bi-polar ion technology has achieved UL 867 including passing the new ozone testing required as of December 21, 2007. Don’t be fooled by other manufacturers claiming to have UL 867 on their products. Many manufacturers had their testing performed prior to the December 21, 2007 amendment requiring the closed chamber test for ozone and a peak ozone test. The UL Standard for Safety for Electrostatic Air Cleaners, UL 867, Section 37 Fourth Edition, December 21, 2007 is a stringent test requiring peak ozone testing 2.0” away from the output of the device as well as a sealed chamber test to confirm ozone does not build up over time. Many manufacturers of bi-polar ion technology, especially tube based ion systems, point to job site test data that may have had inaccurate sensing equipment and may have relied on the cooling coil condensate to reduce ozone levels before entering the space where the test equipment would have been located. The new UL 867 ozone test proves that if an electrostatic air cleaner (bi-polar ion generator) does not produce ozone in excess of acceptable levels of 0.05 PPM in a closed chamber, it will not produce ozone above acceptable levels in a duct. GPS has set the new standard for negligible ozone generation. The peak ozone test revealed a maximum ozone level of 0.0033 PPM! That is 15 times lower than the limit allows! If you are an engineer specifying ion systems on new construction, retrofit or renovation projects, specify the test standard that protects you and the owner, UL 867-2007. If you are an end user, make sure your product supplier meets the standard mentioned herein. If you have any questions, feel free to contact GPS or one of their Representatives today.
