Choosing the right oxygen concentrator for your needs and lifestyle can be stressful, especially when it’s your first time buying one or it’s been a while since you’ve upgraded, Oxygen concentrators aren’t something you can go to the store and try on, which is exactly why we’ve created a guide on how to compare oxygen concentrators, in-depth oxygen concentrator reviews, and side-by-side oxygen concentrator comparisons.
To help you choose the right oxygen concentrator, we’re highlighting the two portable oxygen concentrators made by Inogen. We’ll give you a side-by-side comparison of both the Inogen One G4 and the Inogen One G5. Once you assess your individual needs, you can decide which machine is best for you.
Inogen One G4 vs. Inogen One G5 Flow Settings
Both the Inogen One G4 and the Inogen One G5 offer a pulse dose method of delivering air. And like all of the Inogen One oxygen delivery systems, both the G4 and G5 are built with Inogen’s Intelligent Delivery TechnologyⓇ that ensures oxygen therapy is delivered efficiently and effectively in all modes of use.
The two portable concentrators differ in the range of oxygen flow settings offered. The Inogen One G4 has three different flow settings, while the newer Inogen One G5 has double that, with six different flow settings. The flow setting you’ll need and use during the day, different activities, and while sleeping will be determined by your doctor
Weight and Size
Inogen’s portable concentrators are known for being the most compact and lightweight portable oxygen concentrators available. Their portability allows oxygen therapy users to continue leading rich and active lives, without the burden of a heavy oxygen tank or bulky concentrator system.
Both the Inogen One G4 and G5 oxygen concentrators weigh under five pounds, however; the G4 model weighs less than the G5. With a single (small) battery, the G4 model weighs only 2.8 pounds, while the G5 model weighs 4.7 pounds with that same battery. The G4 model is about seven inches tall, six inches long, and about three inches wide. The G5 model is a little more than eight inches tall, seven inches long, and about three inches wide.
While the G4 weighs 1.9 pounds less than the G5, the G5 boasts a longer battery life. The battery life of the Inogen One G4 is up to 2.6 hours with the single battery and up to 5 hours with double battery. The G5 has one of the longest battery lives on the market — up to 6.5 hours with the single battery or 13 hours with the double — making it an ideal oxygen delivery system for on-the-go individuals.
The length of battery life will depend on which setting the machine is on, along with the size of the battery (single or double).
