Purpose of Review <p>This manuscript reviews the impact of important indoor environmental exposures on pediatric asthma, with a focus on recent literature in the field.</p> Recent Findings <p>Studies continue to support an association between numerous indoor aeroallergens and air pollutants found in homes and schools and increased asthma morbidity overall. Several recent home and school intervention studies have shown promise, though results have been overall mixed.</p> Summary <p>Indoor environmental exposures contribute to the development of asthma and impact asthma morbidity. Further research is needed to improve our understanding of how to optimize mitigation of these indoor exposures to significantly affect asthma outcomes.</p>
