The science, made simple
Not a gimmick. A physio technique you can hold.
Decades of clinical use
PEP therapy began in Denmark and is used by physiotherapists worldwide to help people with excess mucus breathe easier.
Same proven design
A Griffith University report (Prof. Norman Morris) found steel-ball oscillating PEP devices perform similarly to the well-known Flutter device across a range of breathing speeds and tilt angles.
More mucus cleared
An early study of people with cystic fibrosis found this style of device helped them clear significantly more mucus than postural drainage and coughing — with no adverse events.
Gets air behind the mucus
Gentle pressure opens extra side-airways, letting air get behind trapped mucus so a cough can move it out.
