The FreeStyle Comfort uses UltraSense™ Breath Detection Technology to deliver oxygen efficiently and precisely. Instead of a continuous flow, the device releases oxygen only when a breath is detected, ensuring each bolus is perfectly synchronized with your breathing. This method reduces oxygen waste while maximizing therapy effectiveness. With five pulse flow settings and a maximum oxygen output of 1050 ml/min, the FreeStyle Comfort meets the needs of most oxygen users and provides flexibility as therapy requirements change.

Unlike traditional oxygen tanks, the FreeStyle Comfort operates on rechargeable lithium-ion batteries, giving you the freedom to move without restrictions. On the lowest setting, the 16-cell battery provides up to 16 hours of runtime, outperforming many competitors in its class. Detailed battery expectations include: Setting 1 (8-cell 8 hrs / 16-cell 16 hrs), Setting 2 (4 hrs / 8 hrs), Setting 3 (3 hrs / 6 hrs), Setting 4 (2.25 hrs / 4.5 hrs), Setting 5 (2 hrs / 4 hrs). The device can be charged using AC power at home or DC power in your vehicle, offering unmatched convenience. Recharge times: 8-cell battery ~3.5 hours, 16-cell battery ~6 hours.

Designed with user comfort in mind, the FreeStyle Comfort features a curved, body-contoured shape that rests naturally at your side. Unlike bulky concentrators, it won't slide or interfere with movement. All controls are conveniently placed on the top of the unit, and the battery can be quickly removed from the bottom for easy replacement. At just 5 pounds with the 8-cell battery and 6 pounds with the 16-cell battery, it's one of the lightest portable oxygen concentrators available. The device is FAA approved, allowing you to bring it onboard commercial flights.
