The article discusses the results of a study which investigated the role of various filter efficiencies in attaining and sustaining clean heating, ventilation and air conditioning components and distribution systems. This study evaluated the Sub-Minimum Efficiency Reporting Value (MERV) 4 to MERV 14 filtration systems in a variety of commercial-building types. It was divided into two phases. Phase one involved nine spaces within five Atlanta, Georgia office buildings. Phase two expanded the number of sites.
