What this trial studies
This randomized control trial aims to determine if using box fans with high-quality filters can reduce asthma symptoms and enhance indoor air quality for children aged 6 to 17 years living in the Duwamish Valley of Seattle. Participants will be divided into two groups: one using fans with MERV 13 filters and the other with sham filters. The study will assess changes in asthma symptoms and lung function, measured by forced expiratory volume (FEV1), alongside monitoring indoor air quality. Participants will complete questionnaires, use peak flow meters, and run the box fans in their homes to gather data on the intervention's effectiveness.
Who should consider this trial
Good fit: Ideal candidates are children aged 6 to 17 years with poorly controlled asthma living in the Georgetown and South Park neighborhoods of Seattle.
Not a fit: Children with unstable housing or shared custody arrangements may not benefit from this study.
Why it matters
Potential benefit: If successful, this intervention could significantly reduce asthma symptoms and improve the quality of life for children suffering from asthma.
How similar studies have performed: Other studies have shown that improving indoor air quality can positively impact asthma symptoms, suggesting this approach may be effective.
