Summary

This study tested whether long-term use of a special breathing filter (Provox Life HME) can improve lung symptoms like coughing and mucus in people who had their voice box removed (laryngectomy). Eighty adults who were at least 3 months past surgery took part. Results showed that using the filter helped reduce coughing and sputum, making breathing more comfortable.
