Summary
This study looked at whether using a HEPA air purifier at home can improve lung health in adults with a type of COPD called eosinophilic COPD. 178 people took part; half received real purifiers and half received fake ones. The main goal was to see if the purifiers helped increase the amount of air they could exhale in one second, a key measure of lung function.
