Clean air trial hopes to ease breathing for rare lung disease patients

This study is testing whether using HEPA air purifiers at home can reduce respiratory symptoms and improve lung function in children and adults with Cystic Fibrosis (CF) or Primary Ciliary Dyskinesia (PCD). Participants will have two purifiers installed in their home and will undergo lung function tests and symptom checks over several months. The goal is to see if cleaner indoor air makes a real difference in their daily breathing and overall health.
