The newest portable oxygen concentrator in CAIRE’s FreeStyle line, the CAIRE FreeStyle Comfort features an ergonomic design that gently curves to fit the user’s body better. The unit is light, weighing just five pounds with a small battery, making it one of the most comfortable portable oxygen concentrators to carry around.

With its competitive price, it is an ideal mobile oxygen concentrator for those who want a powerful and ergonomically designed machine.

The FreeStyle Comfort portable oxygen concentrator is an elegant machine, rounded and curved to rest naturally against the user’s body when wearing it. It is a sleek white color, with a subtle blue logo on the front side. At the bottom are two air intake filters, the power port receptacle tab, the battery pack, and the battery pack release button. The top side of the unit features the control panel, which is easy to access when the machine is standing upright or carried at your side.

Dimensions: 7.3 inches wide x 3.1 inches deep x 10 inches high with the small 8-cell battery (11 inches high with the large 16-cell battery) Weight: 5 pounds with the small 8-cell battery (6 pounds with large 16-cell battery) Power: 100–240 VAC, 50-60Hz

At a meager five pounds with a small 8-cell battery and six pounds with a large 16-cell battery, the FreeStyle Comfort oxygen concentrator indeed is portable. Although it is small, it still offers five pulse dose settings and can deliver up to 1050 mL of oxygen per minute. With a small battery at a setting of 2, the unit will last 4 hours on average; at a setting of 5, it will last two hours.

The unit features CAIRE’s sensitive breath detection technology, UltraSense. When the unit doesn’t detect a breath for 15 seconds, it will automatically deliver oxygen at its current setting at 20 breaths per minute until it detects another breath.

The control panel on the FreeStyle Comfort features just three buttons and a large color LCD display, which makes it easy for anyone to operate. On the right-hand side of the display is the power button; on the left are the “Increase Flow” and “Decrease Flow” buttons, which allow you to control the flow setting. All three buttons glow in the dark so you can see the control panel in low lighting.

The LCD screen displays the current flow setting, the battery charge, whether the unit is plugged into AC/DC power and an alarm indicator should an issue arise. Because the unit is also FAA approved, the screen will also display an airplane symbol when the unit is in Airplane mode.

Caring for the unit is easy: users must only clean the air intake filters on a weekly basis, though you may be advised to clean them more frequently. Users can also use a damp cloth and a mild disinfectant to clean the outside of the unit as needed.

The unit comes with a 3-year warranty on the unit as well as 3 years on the sieve beds. The battery and accessories are covered for 1 year making this one of the best manufacturer warranties on a portable oxygen concentrator.

The CAIRE FreeStyle Comfort comes with either a small 8-cell battery or the large 16-cell battery, power supply with AC input cable, vehicle power cord, carry bag and strap, cannula, and a user’s manual.
