Improved Filtration and the Residential Environment: An Intervention Research Project to Determine the Relevancy and Efficacy of Particulate Filtration in Improving Air Quality Conditions in Residences

摘要

This paper reports the results of a field evaluation project that demonstrates and documents the efficiency and efficacy of selected filtration products in residential application using fractional size efficiency and particle conting techniques. The emerging interest in indoor air quality is driving the need for more representative, accurate, and meaningful efficiency data on filtration products used in residential applications. This study evaluates and compares several efficiency levels of filtration in all zones of typical air-conditioned residences. Indoor conditions are compared to outdoor particle concentrations to establish the overall system efficiency of particle reduction within the occupied space.
