Airsep® FreeStyle™3 Portable Oxygen Concentrator (Import from USA)

Airsep® FreeStyle™ Portable Oxygen Concentrator
(Import from USA)

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.
