Caire Freestyle Comfort Portable Oxygen Concentrator

Caire FreeStyle Comfort Oxygen System

With its ergonomic shape, the lightweight Caire FreeStyle Comfort portable oxygen concentrator rests against the natural curves of your body, making it comfortable to wear while on-the-go. Equipped with user-replaceable batteries, this new oxygen therapy device meets FAA guidelines for all commercial air travel and allows you to extend your time away from home.

The Caire FreeStyle Comfort oxygen system is a lightweight portable oxygen solution: Weighing as little as 5 pounds, the FreeStyle Comfort portable oxygen machine can go anywhere you want to go, at a moment’s notice. You simply pick it up and walk out the door. The Freestyle includes an AC adaptor to plug into the wall, a DC adaptor to plug into your vehicle and is battery powered. You can choose between a standard size battery or an extended battery and we have special discount battery bundle packages on sale, too.

The Freestyle unit includes a protective carry case and padded shoulder strap. There is a back pack available as an optional accessory item.

The innovative new FreeStyle uses improved UltraSense technology to deliver oxygen.

UtraSense technology: The sensitive breath detection technology ensures oxygen is delivered to you when you need it. Where other concentrator models may miss a breath; not the new Freestyle. The Freestyle system also includes a *No Breath Alert* which signals the machine to start *Auto Pulsing* Oxygen.

The air we breathe contains approximately 21% oxygen, 78% nitrogen, and 1% 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, or purity, of oxygen delivered to you. The FreeStyle Comfort combines advanced oxygen concentrator and oxygen conserving technologies to create a portable device that allows for extreme portability and mobility. The advanced pulse flow delivery quickly senses when you inhale and delivers a pulse dose of oxygen. Pulse flow delivery is ideal for any users with an active lifestyle and enjoy having time away from home. Pulse systems conserve oxygen and extend battery life as opposed to continuous flow devices. The FreeStyle Comfort is lightweight enough to be carried via handle, shoulder strap, or backpack. It can be operated on AC (wall), DC (vehicle) or rechargeable battery power.

The Freestyle Comfort system is intended to provide supplemental oxygen to you who have been prescribed oxygen therapy from a doctor. The Freestyle Comfort oxygen concentrator doesn’t store or contain oxygen, making it very safe, thus why it is FAA approved for use on all airlines. The Comfort POC never needs to be refilled, and the battery can recharge anywhere via AC or DC power. This makes you more independent and self-sufficient in terms of in-home use, ambulation (both in and outside of the home), mobility, and overall lifestyle.
