Caire FreeStyle Comfort Portable Oxygen Concentrator

Easy to use 

The FreeStyle Comfort brings usability and convenience to a new level. A single button push starts the device and it takes less than 2 minutes to start delivering oxygen. The machine’s sound level is only 43 decibels, so you can use it with confidence whether at home, in a restaurant, or at church. It’s also fully FAA certified and approved for airline flight on most major airlines.

Light, Ergonomic & Comfortable  

The FreeStyle Comfort is just 5 lbs in weight. It is also easily carried around with the included case and strap. In addition, the unit itself was designed with an innovative curve which fits against your body snugly as you walk. This curve cleverly limits the amount of swinging and banging from your normal stride.

How does oxygen concentrator deliver what you need?

The air we breathe contains approximately 21% oxygen, 78% nitrogen, and 1% of other gasses. With the FreeStyle Comfort portable oxygen concentrator system, the ambient air is drawn into the machine through the air intakes. The air then passes through an adsorbent material called molecular sieve. This material separates the oxygen from the nitrogen and allows only the oxygen to pass through. The result is a flow of medical grade, high concentration/purity oxygen delivered to you.

AutoDose Safety

The AutoDose feature monitors your breathing closely. If it detects no breathing, the true brilliance of this machine shines through. The FreeStyle Comfort can instantly deliver automatic pulses of oxygen at a rate of 20 breaths per minute until normal breathing has resumed.


The FreeStyle Comfort's battery can last up to four hours at Setting 2.  
To give you peace of mind the unit includes an industry-leading 3 year manufacturer warranty that covers the unit and a 1 year warranty that covers the sieve beds. This is the only unit on the market with a warranty on sieve beds, a benefit that could save you hundreds of dollars. There is also a 1 year warranty for the battery and power supplies.
