At less than 5 lb (2.3 kg), FreeStyle by AirSep is the only portable oxygen concentrator tailored specifically for those patients who know no boundaries. Bold and provocative like its name suggests, FreeStyle captures the heart of what it means to live the good life — without limitation. This portable concentrator offers the same weight advantage of a contents-based system, yet provides an unlimited supply of oxygen.

FreeStyle's miniature batteries all fit inconspicuously in an exclusively-designed accompanying AirBelt. This battery belt offers not only function but fashion for those who won't leave home without the assurance of additional hours on FreeStyle. And AirBelt is so lightweight and ergonomically correct that one can easily forget that it's being worn.

FreeStyle is offered as an ensemble consisting of the portable concentrator, shoulder tote, and matching leather AirBelt.
