Impact/Purpose:

Airborne particles in buildings, whether due to intentional dissemination or natural occurrance, can have very serious impacts on the health of the occupants. Many organizations have issued guidance documents regarding methods for reducing airborne particle concentration.. To provide some practical information for building air quality methodology design, the U.S. EPA's Office of Research and Development(ORD) contracted with Battelle to evaluate the performance of a wide range of commonly used ventilation filters and whole-house in-duct electrostatic air cleaners(EACs).
