Portable Oxygen Concentrator Comparison in Detail

Now that you have compared our Inogen One models, you can explore the differences in a little more detail. Read through this portable O2 concentrator comparison before making your final decision on which Inogen One model is right for you.

Portable Oxygen Concentrator Comparison: Weight and Dimensions

Every Inogen One model is designed with size and weight in mind, because our goal is to improve your freedom, mobility and independence. Though each of our portable oxygen concentrator models is under 5 pounds, each model offers different benefits so that you can choose the option that fits you best. Our Inogen One G4 model is one of the smallest portable oxygen concentrators on the market today, weighing just 2.8 pounds and measuring about the size of a one-pound bag of coffee. If you prioritize portability over all other features, this is your model.

The Inogen One G5, our newest model, is a bit larger at 4.7 pounds and a bit smaller than your standard coffee table book, but it offers more flow settings and the longest battery time. The Inogen One G3 comes in at 4.9 pounds and, while slightly larger than the Inogen One G5 in its size and weight, it also provides more flow settings than the Inogen One G4. Still, if size and weight are among your top considerations, the Inogen One G4 is likely to be your top contender. 

Portable Oxygen Concentrator Comparison: Flow Settings and Use

Your oxygen prescription plays heavily into which Inogen One model best meets your oxygen needs. If you need a variety of different flow settings throughout the day, the Inogen One G5 offers six pulse dose flow settings—more flow settings than ever before, even in a home oxygen concentrator comparison. These six flow settings give you the greatest flexibility, which is especially helpful if you travel frequently. The Inogen One G3 offers five pulse dose flow settings, while the Inogen One G4 offers three. Talk to your doctor about how many flow settings you need to determine the right model for you. If you do intend to travel with any of our Inogen One models, rest assured that all of our portable oxygen concentrators are designed for stationary, portable and travel use, and each model meets FAA requirements for use on an airplane. 

Portable Oxygen Concentrator Comparison: Noise Level and Battery Duration

Inogen has worked hard to minimize the impact of our oxygen products on your daily life. Each Inogen One model is extremely quiet to ensure you can carry on conversations, watch TV or read the newspaper without the sound of your oxygen concentrator overwhelming you. In fact, even the loudest Inogen One model, the Inogen One G4, only has a noise level of 40dBA, which is the same as a quiet library.[1] The Inogen One G3 is even quieter at 39dBA, while the latest model, the Inogen One G5, is the quietest at 38dBA. 

Moreover, our Inogen One models offer a variety of battery durations, depending on the size of the unit. The smallest unit we offer, the Inogen One G4, also has the shortest battery life to maintain its small size. Still, it offers up to 2.7 hours on setting 2 with a single battery. The Inogen One G3 is a larger unit and, accordingly, can offer up to 4.7 hours on setting 2 with a single battery. Our latest unit, the Inogen One G5, offers up to an impressive 6.5 hours of battery life on setting 2 with a single battery. If you are looking for the quietest unit with the longest battery life, the Inogen One G5 is your ideal pick. 

Portable Oxygen Concentrator Comparison: Incorporated Technology and Power Sensing 

After reading our home oxygen concentrator comparison, you’ll notice each of our Inogen One models offers innovative technology to make the user experience as easy as possible. Every model offers our Intelligent Delivery Technology®, as well as offering auto-sensing AC power supply and DC power supply for mobile use in vehicles. Additionally, our two newer models, the Inogen One G4 and G5, offer Inogen Connect App capabilities and Bluetooth capabilities. With Inogen Connect, you have quick and easy access to updates and information about the functionality of your unit to help keep you informed.

Portable Oxygen Concentrator Comparison: Operation and Warranty

When it comes to our Inogen One models, operation and warranty are the same across the board. Each Inogen One model features simple control functions and an easy-to-read LCD display, so you can trust that your portable oxygen concentrator will be easy to use. Each model comes with a 3-year Standard Warranty; however, you always have the option to purchase a Freedom Package, which comes with extra batteries and a Lifetime Warranty.

No matter which benefits are most important to you, this portable O2 concentrator comparison can help you choose the Inogen One model that will best improve your quality of life. Oxygen. Anytime. Anywhere.
