Breathing Should Be Easy—But for Millions, It Isn’t.
If you often find yourself short of breath, struggling to clear your airways, or waking up congested and tired, know this: You’re not alone.
Millions of people live with daily breathing challenges that can feel invisible to others, but deeply affect your quality of life.
The reasons may differ, but the result is the same: your lungs aren’t working as easily as they should, and your body isn’t getting the air it needs.
And that’s exhausting.
At WellO2, we understand how frustrating and isolating this can feel. That’s why we created a proven, drug-free solution to help restore what breathing should feel like: clear, calm, and effortless.

- Airway inflammation
- Seasonal symptoms and stuffy sinuses
- Coughs and throat irritation

Testimonials
10/10 from me
From the moment the product arrived I was impressed… I have definitely felt better since using it. I have not woken as often with an irritable cough as I did before.

EVELYN, UK
I feel fantastic!
I was reluctant to try something as simple as steam for my breathing issues, having had 43 years of poor breathing. But from the first use, I knew I had made the right choice with WellO2.

NIKOLA K., UK
Thank you for a brilliant product!
As a professional vocalist, having had a couple bouts of sinusitis and doing some dusty house renovations for the past few months, I feel Wello2 not only cleanses my respiratory system, but is also strengthening it.

MIKE S., UK
Thank you WellO2!

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.

- WellO2 breathing trainer
