GENERAL VENTILATION AIR FILTER TESTING LABORATORY VERIFICATION The Research Triangle Institute (RTI) and the U.S. Environmental Protection Agency (EPA) under the Environmental Technology Verification (ETV) Program have established a laboratory verification program for general ventilation air filters. The goal of the ETV program is to verify the environmental performance characteristics of commercial-ready technologies through the evaluation of objective and quality assured data so that potential puchasers and permitters are provided with an independent and credible assessment of what they are buying and permitting. RTI's program covers products used indoors, including the measurement of particle size dependent efficiency for filters used for general ventilation. The test protocol is based on the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) proposed standard 52.2, Method of Testing General Ventilation Air-Cleaning Devices for Removal Efficiency by Particle Size. The purpose of the general ventilation air filter testing laboratory verification is to establish laboratory inter-comparability. Candidate laboratories must have 1) all necessary test equipment; 2) completed system qualification measurements requirements as specified by ASHRAE 52.2P test method; and 3) a quality management system. The verification program will consist of testing up to nine filters during which an onsite audit will be conducted.
