This standard establishes procedures to measure the ability of air-cleaning devices to remove dust as they become loaded with standard synthetic dust. The dust-removal performance is measured in two ways: first by the percentage of the weight of the synthetic dust captured by the filter (ASHRAE weight arrestance) and second by comparing the blackening of targets both upstream and downstream of the air-cleaning device using ambient atmospheric dust (ASHRAE dust-spot efficiency). The procedures in this standard do not measure the ability of the air cleaner to remove particles of specific diameters. This standard is not intended for testing air cleaners exhibiting ASHRAE dust-spot efficiencies of greater than 98%.

Since about 1980, asthma prevalence and asthma-related hospitalizations and deaths have increased substantially, especially among children. Of particular concern is the high mortality rate among African Americans with asthma. Recent studies have suggested that indoor exposuresâ€"to dust mites, cockroaches, mold, pet dander, tobacco smoke, and other biological and chemical pollutantsâ€"may influence the disease course of asthma. To ensure an appropriate response, public health and education officials have sought a science-based assessment of asthma and its relationship to indoor air exposures. Clearing the Air meets this need. This book examines how indoor pollutants contribute to asthmaâ€"its causation, prevalence, triggering, and severity. The committee discusses asthma among the general population and in sensitive subpopulations including children, low-income individuals, and urban residents. Based on the most current findings, the book also evaluates the scientific basis for mitigating the effects of indoor air pollutants implicated in asthma. The committee identifies priorities for public health policy, public education outreach, preventive intervention, and further research.
