CAIRE, Inc. Portable Oxygen Concentrator Costs by Model
CAIRE Inc. manufactures three portable oxygen concentrators with a variety of oxygen dosages and delivery methods. An extensive line of accessories, from carrying cases to tubing, is available for each model. All three models are FAA approved, so you can safely travel with these portable oxygen concentrators on planes, buses or other modes of transportation.
Each CAIRE portable oxygen concentrator comes with a user manual and quick start guide. Customers have access to detailed online video tutorials for easy reference and assistance with operating and setting up the products. Instruction includes unboxing and safety videos.
CAIRE Focus Portable Oxygen Concentrator
CAIRE’s Focus is the company’s smallest portable oxygen concentrator and is not much bigger than your palm. Focus uses breath-sensing technology to deliver oxygen only as you inhale instead of a continuous flow. Weighing under two pounds and worn over the shoulder or clipped to a belt, the Focus battery life is three hours. The optional backup battery is handy while traveling. CAIRE Focus functions on AC or DC power with its universal plug and power supply.
CAIRE FreeStyle Portable Oxygen Concentrators
CAIRE’s FreeStyle line offers two lightweight models to choose from with the FreeStyle and FreeStyle 5 with automatic oxygen dose adjustments.

The FreeStyle weighs under five pounds with three pulse settings for oxygen delivery. This portable oxygen concentrator runs up to seven hours on the two batteries included with the FreeStyle. Like the Focus, the FreeStyle utilizes breath detection to deliver oxygen and operates on battery, or AC or DC power.
The FreeStyle 5 is designed specifically for those living with COPD. FreeStyle 5 has all the features of the FreeStyle but is slightly larger, yet still very lightweight. This portable oxygen concentrator runs for five hours using both batteries. The FreeStyle 5 automatically adjusts the bolus (oxygen volume) based on your breath rate, so you continually get the right amount of oxygen as your breath rate changes.
CAIRE Eclipse 5 Portable Oxygen Concentrators
The Eclipse 5 from CAIRE Inc. is a portable oxygen concentrator with wheels to move the portable oxygen concentrator with you, similar to a rolling suitcase. Designed with CAIRE’s proprietary Automat technology breath sensing and automatic bolus adjustment, the Eclipse 5 ensures COPD patients receive the right oxygen dosage regardless of breath rate. This portable oxygen concentrator runs on AC or DC power, or batteries.
The Eclipse 5 can deliver higher bolus doses than smaller models and the highest pulse dose available in an oxygen concentrator. The Eclipse 5 is also a continuous flow portable oxygen concentrator. Battery life is two hours per battery on continuous flow or five hours on pulse flow.
Other CAIRE Oxygen Concentrators
CAIRE’s Companion 5 is a home oxygen concentrator, weighing under 40 pounds to move with ease on wheels around the house. The Companion 5 is a continuous flow model priced at $800 and operates on AC power. CAIRE includes a humidifier stand, and the Companion 5 has a large easy-to-read display with a space-saving narrow profile.
AirSep and SeQual are divisions of CAIRE Inc. Both companies manufacture oxygen devices for use in medical and industrial applications. AirSep portable oxygen concentrators are light and easy to carry, but we did not find CAIRE’s breath detection technology in this line. SeQual manufactures the Eclipse 5 portable oxygen concentrator which appears to be equally equipped compared to CAIRE’s identically-named model.
