Bronchiolitis Recovery and the Use of High Efficiency Particulate Air (HEPA) Filters

IDeA States Pediatric Clinical Trials Network·interventional·Posted Nov 14, 2022·Updated Oct 2, 2025

In Brief

A clinical study evaluating Winix 5500-2 HEPA filtration units for Bronchiolitis. Completed, enrolled 230 participants across 17 sites.

Detailed Summary

This is a multi-center, parallel, double-blind, randomized controlled clinical trial. Children \<12 months of age hospitalized with bronchiolitis are randomized 1:1 to receive a 24-week home intervention with filtration units containing HEPA and carbon filters (in the child's sleep space and a common room) to improve indoor air quality (IAQ) or to a control group with filtration units without HEPA and carbon filters. The HEPA intervention units and control units will be used for 24 weeks after pre-intervention IAQ measurements. Children are followed for respiratory outcomes over the pre-intervention and intervention periods.
