Customer will receive an Inogen One G5 or OxyGo Next depending on availability.
The Inogen One G5 is a portable oxygen concentrator (POC) designed to provide users with freedom and independence by delivering oxygen therapy on the go. With 6 flow settings, 3 more than the Inogen One G4, the Inogen One G5 is a versatile portable oxygen concentrator for patients with higher oxygen requirements. It meets FAA requirements for travel and is covered by a 3-year warranty. With its reliable, pulse-dose based Intelligent Delivery Technology, the G5 is powered to provide medical grade oxygen delivery all day, every day.
The G5 is designed to be lightweight and compact, making it easy to carry around for daily activities or travel. It comes with a shoulder carrying case for added convenience. An optional backpack is also available for this device.
Unlike most other device, the Inogen G5 has user replaceable sieve beds (columns). Sieve beds are what produce the air we breathe into pure oxygen. Most portable oxygen concentrator brands require you to send in your unit for service in order to replace the sieve beds. With the Inogen G5, you can do this yourself right at home!
One of the key features of the G5 is its extended battery life. It offers users the option of using either a standard or extended battery configuration, depending on their needs. The double battery configuration can provide double the usage hours, allowing users to stay active without worrying about running out of oxygen.
The G5 offers a range of flow settings to accommodate different oxygen therapy needs. It provides pulse flow settings ranging from 1 to 6, allowing users to adjust the flow rate based on their prescription and activity level.
The device is designed with a user-friendly interface, featuring easy-to-read LCD displays and simple control buttons. This makes it easy for users to adjust settings and monitor their oxygen therapy.
Inogen takes safety seriously, and the G5 is equipped with various safety features to ensure reliable operation. These include alarms for low battery, low oxygen purity, or malfunction detection.
The G5 is FAA (Federal Aviation Administration) approved for in-flight use, allowing users to travel by air with their portable oxygen concentrator.

The person helping me (Eric) was very helpful, polite and informative, this is a very good machine, a tad heavy with the larger battery but I would not be able to function without it. THANK YOU. A. O. 😎

Easy to use and instructions are easy to understand. The unit is just a bit heavier than expected but not intolerable.

We bought this for a friend whose medical insurance would not approve her for a portable device. She has used it every day due to her terminal condition. Her doctor was amazed how much better she looked and was surprised we were able to get this for her. To say this is life changing doesn’t even come close to how it has affected her life. She feels better and her quality of life has improved 10 fold. We were so happy how quick the service was and how easy this company is to work with. Thank you!
