Breathe Better. Train Smarter. Feel the Difference.

The WellO2 Steam Breathing Trainer includes three coloured mouthpieces for comfortable steam inhalation through the mouth. A nasal mask is also included for effective steam breathing through the nose.

Why use a Nasal Mask?

Breathing through the nose naturally filters, warms, and humidifies the air, promoting healthier lungs and more efficient oxygen exchange. Using a nasal mask with your WellO2 device helps you:

  • Clear nasal congestion – enhance your breathing exercises by focusing airflow through the nasal passages to clear congestion.
  • Support Nasal Health – Encourages natural nasal breathing to open and clear nasal passages.
  • Strengthens Upper Airway – Regular training helps tone and support the naso-pharyngeal muscles, improving airflow during rest and sleep.

Still Have Questions? We’ve Got Answers.

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 is used to perform guided respiratory exercises. The user first exhales into the device and then inhales the air back through it. During this process, the device provides gentle resistance for both exhalation and inhalation, while also delivering warm steam into the airways. This resistance training strengthens the respiratory muscles, and the warm steam helps open and moisturise the airways.

Can the WellO2 device be used by multiple people?

Thanks to the device's own cleaning program and personal mouthpieces, the WellO2 device can be used by multiple people. The package includes three differently colored mouthpieces for easy identification. Other parts of the device are suitable for shared use.
