AirSep’s FreeStyle™ portable oxygen concentrator is one of the smallest and lightest on the market. Inside the FreeStyle, oxygen is concentrated to 90%, and is then delivered to the patient through one of three different pulse dose settings. Thanks to UltraSense™ technology, the pulse dose delivery is more sensitive and efficient than ever before.

The FreeStyle is compact and fits into a convenient, fashionable bag so that you can take it just about anywhere. It boasts a 3.5 hour battery life between charges, and is even FAA approved for in-flight use. If you are looking for even longer battery life, consider the optional AirBelt. Worn around the waist, it provides 7-10 extra hours of ambulation between charges. Experience freedom and self-sufficiency like never before -- no more lugging around massive oxygen tanks! 

On top of its incredible portability, the FreeStyle also offers UltraSense technology, which ensures the right amount of oxygen precisely at the first phase of inhalation. This provides oxygen when you need it most, while conserving it during exhalation. UltraSense technology is not impeded or diminished with longer tubing either – the FreeStyle can be used with up to 25 feet of tubing without sacrificing performance. The result of this advanced intelligence is a more efficient, reliable, and sensitive pulse flow.
