The International Standards Organization is preparing to issue a new standard for testing and rating air filters. The procedures of the standard include a novel calculation of filter efficiency for three different particle size ranges, when the filter operates on a defined particle-size distribution in the filtered air. The rating system is based on these calculated efficiencies, and provides an index of the filter's effect on indoor air quality. The calculation procedure relates filter performance to typical urban and rural air pollution conditions, and can offer some evaluation of the effect of local air pollution conditions on filter performance.
