MyBreath Smart Mouthpiece
The MyBreath Smart Mouthpiece is designed for use with the WellO2 Steam Breathing Trainer to help you measure, track, and monitor improvements in your breathing. By capturing detailed breathing data during training, MyBreath allows you to better understand how your lungs and airways are functioning and how your breathing develops over time.
When used with the WellO2 Steam Breathing Trainer, the MyBreath Smart Mouthpiece measures respiratory muscle strength, airflow in the bronchial tubes, and overall breathing capacity. This makes it possible to follow your progress and improve your breathing more effectively—right from the comfort of your home.
The MyBreath Smart Mouthpiece works seamlessly with the WellO2 app and is used just like a regular WellO2 mouthpiece. Breathing performance is measured through guided tests in the app, with results automatically saved for easy tracking. These insights help you understand your day-to-day breathing and support training tailored to your personal goals and needs.
What you can monitor with MyBreath
- Breathing power – shows how efficiently your respiratory system performs in everyday situations
- Breathing capacity – indicates not only lung size, but how much of your lungs you actively use
- Airflow – reflects how open the airways and bronchial tubes are, and how freely air moves into the lungs
WellO2 App
In addition to breathing tests, the WellO2 app offers a wide selection of guided breathing exercises, making training motivating and easy to follow.
The app includes exercises designed to support different needs, such as relieving cold symptoms, strengthening respiratory muscles for sports, caring for your voice before important performances, or calming your breathing before sleep. The WellO2 app is free to download from your phone’s app store.

What is WellO2?
WellO2 is a lung-strengthening breathing exercise device that combines inspiratory and expiratory counter pressure breathing and the inhalation of warm steam. The device improves and maintains the condition of the respiratory system.
How does it work?
The device works so that the user performs respiratory exercises with the device. Initially, the user exhales into the device and then inhales the air back into their lungs from the device. The device creates a resistance for breathing and at the same time produces warm steam in the airways. The counter pressure breathing strengthens the respiratory organs while the warm steams opens and moisturizes the respiratory airways. In only one device there are more than one breathing and wellness methods.
