Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are Alaska Native families residing in homes that use woodstoves for heating or have tobacco smokers present.
✕Probably not a fit
Patients who plan to move during the study period or already use HEPA air purifiers will not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This study focuses on improving indoor air quality in homes of Alaska Native children in the Yukon-Kuskokwim Delta, where poor air quality is linked to respiratory diseases. Participants will use HEPA air purifiers to reduce particulate matter (PM2.5) in their homes, which is often elevated due to wood stove use and tobacco smoke. Families will monitor their child's respiratory symptoms weekly over a 12-week period while using the air purifiers. The goal is to assess the impact of improved air quality on the health of these children.
Why it matters
Potential benefit: If successful, this study could lead to significant improvements in respiratory health for children living in homes with poor air quality.
How similar studies have gone: Previous studies have shown that HEPA air purifiers can effectively reduce indoor air pollution, suggesting potential success for this approach.
