Immediately Easier to Breathe and 20% More Breathing Power in One Month
Designed in Finland. Inspired by Clean Air.
Where Inspiration Meets Innovation
In the remote, fresh-air surroundings of Finland’s lake country, Aulis Kärkkäinen found his lungs at their best — until illness forced him to think differently. A problem-solver by nature, he turned his focus to the one part of the body we all rely on but seldom train: our respiratory system.
Aulis envisioned a device that’s more than just a gadget — one that brings medical precision into everyday breathing. That idea gave rise to WellO2: a tool born in Finland, engineered by people who believe that every breath matters.
Precision, Simplicity, Finland-designed
Guided by Aulis’ experience — both professional and personal — the WellO2 breathing trainer was developed in Finland by experts in healthcare, well-being, and technology.
Combining the latest scientific research with technical innovation, it offers a medication-free way to support and improve respiratory wellness.
The design is built on three clear pillars:
- Adjustability: Training levels that grow with you — from gentle resistance to stronger muscle challenge.
- Usability: A sleek, intuitive form that fits your hand, is easy to clean, and ready wherever you go.
- Durability: Designed with Nordic attention to quality, made with components built to last.
This is a tool for anyone who wants to breathe easier, stronger, and clearer — trusted by users and professionals alike.
Train Your Breathing. Change Your Life.
With WellO2, you’re joining the same mindset that motivated Aulis: treat your breathing as a foundational wellness habit. Just a few minutes a day can unlock stronger respiratory muscles, better airflow, and a quieter, calmer natural rhythm.
Whether you’re recovering from illness, pushing performance boundaries, or simply seeking daily well-being, this Finnish-engineered trainer is your partner. And just like Aulis started with a vision on the shores of a lake, your journey begins today — one breath at a time.
Breathe Better. Train Smarter. Feel the Difference.
A nasal mask is included with the WellO2 breathing trainer and is designed to enhance your breathing exercises, ensuring a comfortable and efficient experience every time. By sealing gently around your nose, the mask allows you to focus fully on your respiratory training without air leaks or discomfort.
Key Features
- Comfortable, Secure Fit – Soft, medical-grade silicone adapts to your facial contours for a snug, leak-free seal.
- Optimised for the WellO2 Breathing Trainer – Connects seamlessly with the WellO2 breathing trainer for precise resistance and effective inhalation/exhalation exercises.
- Hygienic and Easy to Clean – Washable materials make maintenance quick and convenient.
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—helping to clear congestion, strengthen the naso-pharynx, and support better, more restorative sleep.
- 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.
Experience cleaner, calmer, and more controlled breathing with the WellO2 Nasal Mask—your essential companion for effective lung training.
