Caire FreeStyle Comfort Portable Oxygen Concentrator

The Caire FreeStyle Comfort Portable Oxygen Concentrator is a lightweight, FAA-approved oxygen solution designed for active oxygen users who value comfort, performance, and reliability. Weighing just 5 pounds, this compact device offers pulse flow settings from 1–5, an ergonomic curved design, and an impressive battery life of up to 16 hours with the 16-cell battery.

Backed by a 3-year warranty (may vary with promotional offers), the FreeStyle Comfort is built to support your oxygen needs whether you’re at home, traveling, or on the move.

UltraSense Breath Detection Technology

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.

Long-Lasting Battery Performance

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. The device can be charged using AC power at home or DC power in your vehicle, offering unmatched convenience.

• 8-cell battery recharge time: ~3.5 hours

• 16-cell battery recharge time: ~6 hours

Comfortable & Ergonomic Design

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.
