The technical paper entitled "Space Charge Control of Secondary Contamination Problems" by Michael H. Pelosi, Jr., is the result of research conducted by, and at the Armor Research Foundation of the Illinois Institute of Technology, beginning January 1962, to determined the CosaTron concept operating performance.
Minimizing Pathogenic Bacteria, Including Spores, in Indoor Air [test paper]
Five experiments were conducted to assess whether aerosolized bacteria, including spores, respond like particulate contaminants to the primary (electrical) forces that control the distributions of small particulate contaminants in indoor air.
Fate of Bioterrorism-Relevant Viruses and Bacteria, Including Spores, Aerosolized into and Indoor Air Environment [test paper]
From the ABSTRACT we learn that the experiments were conducted to assess whether aerosolized bacteria, including spores, respond like particulate contaminants to the electrical forces that control the distribution of small particulate in a room. Such responses would suggest a minimizing infection in office, hospitals, nursing homes, schools, and other such facilities. The results indicate that organisms do respond like particulate contaminants to typical electrical forces in the room.
Documentation of the CosaTron Effect and Its Influence on Airborne Respirable Particles [test paper]
Over a thousand tests were performed on smoke particles in a test chamber with CosaTron on and off, with a 55% filter. CosaTron caused over a 50% reduction in airborne respirable particles in the conditioned space without the benefit of any outside ventilation air.
COSA/TRON Does Not Produce Ozone [test paper]
Two types of tests were performed -- a series of time-exposure photographs and Mast Oxidant Monitor readings. There was no corona present in the photographs, nor was there corona produced ozone detected by the Mast Oxidant Monitor.
An Effective Means of Minimizing Contamination [test paper]
This paper shows that in-duct electrical fields accelerate the natural process of coagulation and indicates that the influence of the CosaTron system in improving air quality is substantial. Beside the improvement in control of particle contaminants, gaseous contaminants and odors, there are also implications for improving the control of bacteria. It also shows that these in-duct fields do not produce ozone.
Change in Room Aerosol Concentration by In-Duct Complex Electric Fields [test paper]
The technical data summarized in "Documentation of the COSATRON Effect and its Influence on Airborne Respirable Particles," and "COSATRON Does Not Produce Ozone," above have been the subject of further review, and the findings have been published in THE JOURNAL OF ENVIRONMENTAL SCIENCES, Jan/Feb 1984.
Influence of High-Frequency High-Voltage Electrical Fields on Perceived Odor Intensity [test paper]
A trained odor panel was used to determine the variation of odor intensity in an animal storage area. According to the subjects, the reduction was about 50%, which changed an unpleasant room to an acceptable one.
Modification of Animal Room Odor by Passing the Room Supply Air Through a Complex Electrical Field [test paper]
The technical data summarized in "Influence of High-Frequency High-Voltage Electrical Fields on Perceived Odor Intensity," above has been the subject of further review, and the findings have been published in The Bulletin of Environmental Contamination and Toxicology, Dec. 1983.
Electrical Charge Distribution and Olfactory Methodology and Theory [test paper]
This paper explains some of the interactions that occur between electrical characteristics that are on odorants, in the space, the materials used in constructing the space, and living organisms that could perceive that odorant.

Aditional information on electrical charge characteristics has been published in The Bulletin of Environmental Contamination and Toxicology, May 1986.
Using In-Duct Electrical Fields to Reduce Particulate and Gaseous Contamination [test paper]
This paper explains the effects of electrical interactions, charging mechanisms, consequences of particle collisions, adsorbancy of gaseous contaminants on particles with resultant effects in the conditioned space.
Control of a Severe Odor Problem in a Building [test paper]
This paper explains in detail the change in the interior environment of a medical examiners office building and autopsy area after the installation of CosaTron. The changes are supported by scientific tests that explain how this change could be expected in similar interior environments.
Modification of Aerosol Size Distribution by Complex Electrical Fields [test paper]
The technical data in "Using In-Duct Electrical Fields to Reduce Particulate and Gaseous Contamination," and "Control of a Severe Odor Problem in a Building," above have been the subject of another review, the findings of which were published in THE BULLETIN OF ENVIRONMENTAL CONTAMINATION AND TOXICOLOGY, June 1985. This paper verifies the occurrence of a particle size shift from fine particles to larger, more collectable particles and a reduction in the space of 94% of the mass of the fine particles involved in the particle size shift.
Reduction of Formaldehyde, Ammonia, SO2 and CO2 Concentration in Room Air [test paper]
The technical data in "Using In-Duct Electrical Fields to Reduce Particulate and Gaseous Contamination," and "Control of a Severe Odor Problem in a Building," above have been the subject of another review, the findings of which were published in THE JOURNAL OF ENVIRONMENTAL SCIENCES, July/August 1986. This paper establishes that certain gases can be more rapidly removed from the conditioned space without the benefit of outside air for dilution.
Control of Building Air Quality [test paper]
This paper discusses how to improve the air quality in animal storage facilities by improving the effectiveness of filters while reducing costs by using cleaned recirculated air to control particle contaminants, gaseous contaminants and odors.
Analysis of Ventilation Strategies and Filtration Procedures for Office Buildings in Taiwan [test paper]
This paper discusses the use of ventilation and filtration procedures to improve IAQ control of typical office buildings in Taiwan. An experiment was conducted to compare the effectiveness of utilizing an air-cleaning device, or a filtration procedure jointly with a ventilation procedure and to compare it with that of an outside air ventilation design alone. A high frequency electrical field device (CosaTron) was used for this experiment because it allows for return air recirculation and for it's snowball effect (contaminant collision) on particles. The results proved that when a ventilation system is combined with an effective filtration procedure (CosaTron), it is as effective as an all-outdoor air ventilation system in maintaining indoor air quality, but using much less energy.
Enhancing Contaminant Control to Mitigate Aeroallergies [test paper]
This paper, published in the Annals of Allergy, Asthma, & Immunology, December 1996, discusses improving indoor air quality for allergy and asthma patients through enhanced filtration effectiveness.
