Air Filtration for COPD in VA Population of Veterans

The goal of this study is to investigate the effectiveness of stand-alone air filtration for improving indoor air quality (IAQ) and chronic obstructive pulmonary disease (COPD) outcomes in a high-risk urban cohort of 80 U.S. military veterans with COPD. Secondary goals of the study are to (1) investigate housing-related factors that may contribute to COPD exacerbation, (2) investigate the utility of using low-cost sensors for indoor air pollution epidemiology studies and for providing actionable or useful information on the quality of their indoor air to patients and their physicians, and (3) evaluate the costs and benefits of using stand-alone air filtration to improve IAQ and COPD outcomes.
