Studies Relevant to Indoor Air Quality

Concentrating on the indoor environments is particularly important for children, since they can spend as much as 90% of their time indoors. Exposure to indoor air pollutants can cause health effects ranging from sneezing and coughing to exacerbations of chronic respiratory disorders such as asthma. American Thoracic Society May 2010

Three recent, high quality, systematic reviews of the available evidence concluded that the implementation of interventions that combine elimination of moisture intrusion and leaks and removal of moldy items help to reduce mold exposure, respiratory symptoms and new onset asthma. This position has also been taken by the National Institute for Occupational safety and Health (NIOSH), many State governments, Health Canada, and internationally by the World Health Organization.

More than 50 epidemiological studies have been performed in different parts of the world. The majority of the studies have found adverse health effects from particulate matter at levels lower than the current federal standard. Particulate air pollution has been associated with increased respiratory illness or chronic respiratory symptoms, asthma aggravation, increased hospital admissions, and premature deaths.

Inexpensive, low-efficiency HVAC filters offer no better particle removal than no filter. Effectiveness of Air Filters and Air Cleaners in allergic Respiratory Diseases: A review of the Recent Literature by James L. Sublett, National Center for Biological Information July 2011

Dampness and mold in homes is associated with increases in several adverse health effects including upper respiratory symptoms, cough, wheeze and asthma exacerbation. Indoor Air Quality Scientific Findings Resource Bank by the Indoor Environment Group of the Lawrence Berkeley National Laboratory with funding support from the U.S. Environmental Protection Agency.

Children living in a high ERMI value home at 1 year of age had more than twice the risk of developing asthma by age 7. Annuals of Allergy, Asthma, & Immunology July, 2012

Housing dilapidation, especially the damage caused by water leaks, is directly linked to the rates of poorly controlled asthma in inner city children. Remediating water damaged buildings has improved the control of childhood asthma. After remediation, emergency room visits and hospitalizations were reduced from 22 visits and 11 admissions to 2 visits and one admission. A reduction in the dosage of medications was possible in all patients and, in some cases, certain medications were taken off following the intervention. Journal of Asthma 2012

Bedrooms with higher levels of particles were linked to more symptoms in the children with asthma. As the concentration of coarse particles got higher, the symptoms increased. Symptoms included coughing, wheezing and chest tightness. This study suggests that finding ways to cut down of the particulate matter in the air may help to reduce the symptoms of children with asthma. Meredith C. McCormack, MD, MHS, an instructor with Johns Hopkins School of Medicine and researchers from the Center for Childhood Asthma in the Urban Environment, which is a joint center of Johns Hopkins School of Medicine and John Hopkins Bloomberg School of Public Health. August 2009

Forced air systems with high efficiency filtration were found to provide the best control of asthma triggers: 30-55% lower cat allergen levels, 90-99% lower risk of respiratory infection through the inhalation route of exposure, 90-98% lower environmental tobacco smoke (ETS) levels, and 50-75% lower fungal spore levels than natural ventilation, portable air cleaners and forced air ventilation equipped with conventional filters.
