Description
Air pollution is the cause of various health concerns. One of the predominant concerns originates from fine particulate matter of 2.5 μm (PM2.5) or less in diameter that is a by-product of chemical reactions in the atmosphere and fuel combustion. This project focuses on assessing a new air filtration enhancement technology in removing PM2.5 concentrations that functions by generating inelastic collisions among particles. In-situ monitoring were undertaken at the Skidmore Owings & Merrill office in Chicago. Outdoor PM2.5 concentrations have been reordered during high variability periods along with indoor-outdoor ratios (I/O) that have been classified by occupancy conditions. The results indicate the effectiveness of the new technology under all levels of human occupancy, especially in indoor-dominated conditions. This is significant in the office environment where occupant density varies depending on the time of the day and where re-circulated air is utilized by HVAC systems (as applied in North America).
