A Clean Technology for Indoor Air Quaility(ST8277-1)

Syracuse University


Air cleaning can be an effective and energy-efficient method for improving indoor air quality (IAQ). The challenge is to find a technology that is effective for all the anticipated pollutants in a particular indoor environment. Indoor air quality in printing/copying environments is a concern for occupational health reasons due to the relatively large quantities of solvents, cleaning agents, oils and toners used. Recently, it has been found that the pollutants in the air around a color copier can have detrimental effects on printing quality (e.g., blurred images and deletions). Syracuse University and Xerox Corporation have teamed to develop methods that combine different filtration media or air purification technologies that remove targeted contaminants for indoor environments and prevent pollutants from entering copier machines.

Project Description

The Contractor shall: characterize the air quality in office, residential, and printing/copying environments, develop a design model and database for selecting air cleaning technologies, use the design model and database to select effective air cleaning methods for printing/copying areas, develop a design manual for using air cleaning technologies to improve IAQ, and prepare technical papers for presentations at appropriate conferences.


This project’s results have been published in several technical articles.

Project Results

Laboratory tests determined the effectiveness of various sorption media and ultraviolet photocatalytic oxidation (UV-PCO) materials for removing the volatile organic compounds (VOCs) commonly found indoors. The sorption media testing found that studied VOCs could be treated with various materials, but that no one material could be used to treat all VOCs. The UV-PCO tests found that this technology could be effective against individual VOCs or mixtures of two or three VOCs. As the number of VOCs in the mixture increased, the rate at which VOCs were removed decreased significantly. The rate of VOC removal and single pass efficiency of the UV-PCO technology were found to vary as the airflow rate through the device changed (e.g., as airflow rate increased, removal rate increased while single pass efficiency decreased, and vice versa as airflow rate decreased). These test results were used to identify promising materials and to develop a library of performance factors for these materials against specific VOCs. Simulation models for sorbent bed filter and honeycomb UV-PCO air cleaners were developed. The simulation models were validated, using the laboratory test results. A design manual was developed to illustrate how the models could be used. The manual and models are available to engineers so the performance air cleaners can be designed or evaluated for meeting specific indoor air quality objectives.
