Goodbye Phlegm. Hello better breathing!

Therabubble™ is an effective and affordable bubble PEP device designed to clear phlegm from the lungs and improve respiratory function.

The modern bubble PEP device

Therabubble™ is proud to offer the modern bubble PEP device, with patented features and technology that make breathing easier. This simple treatment can be used by adults and children with a variety of respiratory conditions.


Therabubble™ works by blowing air into a specially designed tube and water container to make bubbles.

This creates positive expiratory pressure (or PEP) in the airways, helping them to open and allow air to move in and out of the lungs. The vibrations created by blowing bubbles also help dislodge sticky mucus in the lungs.

With better airflow, phlegm can be coughed up and cleared and patients can breathe better.

Designed by a Physiotherapist

Therabubble™ was co-designed and created by Kathryn Potter, an Advanced Physiotherapist who has worked in hospitals for over fifteen years. Kathryn has a special interest in respiratory health and is a member of the Australian Physiotherapy Association Respiratory special group.

Kathryn saw a need for an affordable, purpose-built bubble PEP treatment. After a number of years refining the design, Therabubble™ was commercialised in 2014. To date, Therabubble™ has helped over 60,000 people around the world to breathe better.
