FAQs

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 to open and moisturise the airways.

The WellO2 device features adjustable breathing resistance, making it suitable for both beginners and experienced users. You can also choose from three temperature settings to personalise the level of warm steam based on your preferences and needs.

The WellO2 breathing trainer can be used for both oral and nasal breathing exercises. When used through the mouth, the warm steam is directed to the throat area. When used with the nasal mask, it also moisturises the nasal mucosa, helps clear a blocked nose, and supports the small muscles in the nose and nasopharynx.

Can the WellO2 device be used by multiple people?

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

What does the package include?

The package includes:

  • WellO2 breathing trainer
  • 3 different coloured mouthpieces
  • Nasal mask and extension hose
  • Breathing regulator
  • Power base
  • User instructions
    • Does the WellO2 device have a warranty?

    Yes, the WellO2 device comes with a 24-month warranty.

    Is there any research behind it? Does the product really work?

    Yes, WellO2 is backed by clinical studies and trusted by over 150,000 users worldwide. You can read more about the clinical studies and in-depth research here.

    Is it suitable for me? I have long-term airway problems

    WellO2 is designed to support breathing for people with a range of challenges, like age-related issues, mild respiratory concerns, or breathing discomfort from airway problems.

    Do not use the device if you have had:

  • Pneumothorax
  • A recent disease or injury of the tympanic membrane
  • A recent surgical operation on your head, chest or abdomen

    • If you are not sure whether you can use the breathing exercise device, please discuss starting the breathing exercises with your GP.

    What’s WellO2 MyBreath?

    MyBreath is a smart mouthpiece used together with the WellO2 breathing training device. It allows you to measure, track, and improve your breathing! It is used together with both the WellO2 device and the WellO2 app.

    With the WellO2 MyBreath smart mouthpiece, you can track:

  • Respiratory muscle strength, which indicates how well the respiratory system can function in various life situations.
  • Respiratory capacity, which indicates the size of your lungs and how much of your lung capacity you utilise.
  • Airflow in the respiratory tract and bronchial tubes, indicating how effectively air can flow into the lungs along with the breath.
