Experience reliable respiratory support in a smaller, smarter form with the VARON Serene 3. 

Designed to deliver medical-grade oxygen at 93 ± 3 % purity from 1 to 3 L/min, this device strikes the perfect balance between performance, size, and energy efficiency. With flow settings adjustable from 1 to 10, it flexibly adapts to your daily needs while maintaining stable oxygen concentration at clinical levels within the 1–3 L range.

Powered by a high-efficiency, oil-free compressor, the Serene 3 operates quietly—ideal for continuous use through the night. Its advanced cooling system ensures steady output with minimal energy consumption, giving you dependable 24/7 oxygen support.

For added comfort, the included humidification bottle allows you to moisten the oxygen using distilled or cool boiled water—optional for those who prefer dry oxygen.

An intuitive control panel with an easy-to-read display makes operation effortless. You can set the automatic timer (10 to 2400 minutes), monitor oxygen concentration and system pressure, and receive instant alerts for power, pressure, or concentration issues.

Compact and lightweight, the Serene 3 moves easily with its smooth-rolling wheels, bringing high-grade oxygen support to any corner of your home.

Combining the functions of an oxygen concentrator and nebulizer, it comes with two nasal cannulas and one nebulizer kit—ready to support both oxygen therapy and medication delivery.

What is the difference between continuous flow and pulsed flow?

Pulse flow concentrators deliver the required oxygen only when you breathe in. While continuous-flow oxygen concentrators provide a constant flow of oxygen, regardless of whether you are inhaling. Continuous flow is suitable for those who need a non-stop oxygen supply, while pulse flow is mainly used on portable oxygen machines for lower power consumption and longer battery life.

What is a nebulizer and nebulizer therapy?

Serene 3 home oxygen concentrator has a nebulizer function.
A nebulizer is a medical device used in respiratory therapy to deliver medication directly into the lungs in the form of a mist. It converts liquid medication into fine particles that can be easily inhaled by the patient. 
Nebulizer therapy involves using a nebulizer to administer medication for the treatment of respiratory conditions such as asthma, COPD, cystic fibrosis, and more. It is suitable for patients of all ages, and is highly effective in delivering medication directly to the lungs, providing quick relief and targeted treatment.

Can I use Serene 3 overnight?

Yes. The high-quality compressor in Serene 3 allows for continuous use 24/7. It operates quietly with a noise level as low as 48 dB, so you can sleep soundly while using it over the night.

Can I use Serene 3 with a CPAP machine?

Yes, Serene 3 is compatible with common CPAP machines. Yet we recommend you check the specifications of your CPAP machine to confirm its compatibility with oxygen machines.
