CAIRE AirSep FreeStyle Comfort Portable Oxygen Concentrator, 5 Pulse Settings

The CAIRE FreeStyle Comfort is one of the quietest and most ergonomic portable oxygen concentrators available, operating at just 39 dBA on setting 2 — quieter than a refrigerator. Its curved body hugs the hip naturally, reducing fatigue during all-day wear. AutoSAT technology automatically adjusts oxygen delivery to match the patient's breathing rate, while autoDOSE ensures a bolus is delivered even if breath is not detected. UltraSense breath detection reliably triggers delivery at low respiratory rates. Five pulse dose settings deliver up to 1,050 mL/min. The included 8-cell battery lasts up to 4 hours; the optional 16-cell battery extends to 8 hours. FAA approved. 3-year warranty on unit and sieve beds — the longest in the industry.
