A Beautifully Engineered European Masterpiece

Designed in the Netherlands by Ohen Group, the Model 5 is crafted from the highest quality materials, from high-purity silica quartz to A-grade stainless steel with no titanium traces. Every component, down to the smallest class A and B ozone-resistant parts, has been carefully chosen for durability and performance. This is a device built to last a lifetime, while providing powerful healing and consistent ozone delivery.

Stunning Design Meets Powerful Performance

The Ohen Model 5 looks as beautiful as it performs. Its new sleek all-white face, familiar Ohen blue buttons, and bright blue digital display and indicators create a premium, modern aesthetic that feels at home in any wellness space. With vents removed and a minimalist design, it’s not just a device — it’s a statement of effortless wellness and refined functionality.

Smart, Intuitive, and Effortless

The Model 5’s all-new interface is a revolution for home ozone therapy. Redesigned software, built from the ground up, works seamlessly to keep you safe and in control without overwhelming you with settings. Timer alerts notify you when therapy sessions end, provide gentle repetitive prompts to turn off oxygen if you’ve drifted off*, and even flag minor faults to ensure reliable ozone output every time.

Continuous sampling and monitoring paired with six intelligent modes unlock intuitive quick actions — pause or stop and reset, or adjust your session in seconds with a single press. For users who need nuanced, timed sessions, you can now set intervals as short as 1 to 5 minutes, perfect for sensitive users or those with higher toxicity.

Reliability You Can Feel

Every detail of the Model 5 has been refined for longevity and peace of mind. The newly constructed brace structure and individually levelled buttons ensures buttons remain responsive and durable*. With new materials, heat is dissipated evenly allowing us to remove air vents and protecting the device from dust, splashes, and other environmental hazards. Integrated oil damage prevention protects your device; say goodbye to servicing every time you forget to detach the tubing from the oil bottle — only a small amount can get in the tube but will never damage the device itself* while software updates keep your device aligned with the latest research and industry standards.

Next generation oxidation resistance is baked into the core of the Ohen Model 5 with gold plating, UV reflective protection and a complete technological redesign. Whether for yourself, your family, or clients in a professional setting, the Ohen Model 5 delivers high-performance therapy effortlessly, every time.

More Power, Less Consumption

Efficiency is at the heart of the Model 5. Producing nearly 70 micrograms per millilitre oxygen, it achieves high ozone concentrations and we've slashed the power consuption with up to 4x less power than older Ohen 4.1 devices* power consumption. One small cylinder refill lasts over 110 sessions, and the auto power-off feature ensures energy is conserved, even when using battery backups.

Designed for the Ultimate User Experience

From home users to doctors and wellness professionals, the Model 5’s adaptable interface prevents therapy mistakes and simplifies every step. Its timer-based operation automatically switches modes, halts ozone production at session completion, and even continues gentle alerts if you’re too relaxed to respond. Using a high-performance medical device has never felt so intuitive or stress-free.

Serviceability and Longevity

Ohen Group ensures that the Model 5 remains repairable, serviceable, and now updatable, reducing electronic waste and carbon footprint while prolonging your investment. Accidental damage or well-used performance degradation can be addressed efficiently and economically, ensuring your device delivers decades of wellness.

Optional Ohen Extended Care Plans offer peace of mind with extended warranties, accidental damage coverage, express replacement services, and priority technical support. This is wellness without compromise, giving you the confidence to enjoy your ozone therapy fully.

Why Upgrade From the 4.1?

The Ohen 4.1 has served you well, but the Model 5 is designed for those who demand more — more efficiency, more reliability, more control, and more beauty in design. From intuitive alerts to enhanced timed sessions, integrated oil protection, and automatic software updates, every improvement was made with you, the therapy user, in mind.

If you’re still using an Ohen 3, there’s no question — this is the device for you. Even for 4.1 owners, the Model 5 elevates your experience, making therapy safer, more efficient, and ultimately more effective.
