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 Muscles.
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 looking to push your performance boundaries, seeking daily well-being, or a product to use as part of a breathing exercise program recommended by healthcare professionals, 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 Steam Breathing Trainer – Connects seamlessly for precise resistance and effective inhalation/exhalation breathing 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:
- Better Nasal Health – Designed for nasal breathing exercises, the nasal mask encourages natural nasal breathing to open and clear nasal passages.
- Support Upper Airways – Gentle resistance training helps tone and support respiratory 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.
