An In-Depth Look at the AirSep FreeStyle 3

The AirSep FreeStyle Portable Oxygen Concentrator is one of the smallest and most lightweight portable oxygen concentrators available on the market today. Standing 8.6" tall and 3.6" deep, the FreeStyle is compact and unobtrusive. This sleek black oxygen concentrator features a durable, hard plastic shell with vents. The FreeStyle comes with an over the shoulder carrying bag that fits seamlessly over the body of the POC.

The FreeStyle's control panel is located at the top of the portable oxygen concentrator. The control panel is covered by a transparent protective case that flips open to display an easy to read LED screen and button controls. The FreeStyle is unique from most other portable oxygen concentrators in that instead of having an on and off switch, the unit turns on by simply pressing the button (1 through 3) that corresponds with the oxygen flow setting you need. The FreeStyle's large, soft buttons are easy to press. In addition to the three pulse dose setting buttons, the FreeStyle also has a battery test button, which displays the remaining battery life in increments of 25% when pressed.

Oxygen Output:

The FreeStyle is a pulse dose oxygen concentrator with three settings available. When used in setting 3, the FreeStyle is capable of delivering up to 332 mL of oxygen per minute with oxygen concentrations of between 87% and 95.5%.
