NCT ID NCT05615870
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether using HEPA air filters at home can reduce respiratory symptoms in infants under 12 months who were hospitalized for bronchiolitis. 230 babies were randomly assigned to have either real HEPA filters or placebo filters in their home for 24 weeks. Caregivers tracked days without coughing, wheezing, or trouble breathing. The goal is to see if cleaner indoor air helps babies recover faster and avoid more doctor visits.
