Inogen One G4 Portable Oxygen Concentrator

The Inogen One G4 portable oxygen concentrator is the smallest, lightest, and quietest unit available.

The Inogen One G4 is designed to run twenty-four hours per day on a setting of one to three liters per minute (1-3 lpm). And it weighs just 2.8 pounds (with one battery)!

Inogen outdid themselves with the G4. Every portable oxygen concentrator (POC) user wishes for the same things. They want a device that is quiet, light, reliable and has a long battery life. We think that Inogen delivered on all of these fronts.

As you may know, we put every portable concentrator that we sell through a series of non-scientific, real-world tests. Here are our thoughts on the G4:

First, we watched television with it. It was quite enough that it wasn’t noticeable. We think it’s the quietest that we’ve tested. Second, it’s the lightest POC available, so it passes that test. Third, we’ve put the G4 on many patients and have yet to have one fail (we did replace a carry bag for a lady that spilled some wine on it). Finally, we found that the battery life was on the higher end of normal (around 4.5 hours). We test all of the units at two liters per minute on pulse mode (that’s the most common prescription that we see).

Do you want to travel with oxygen? The Inogen One G4 is approved by the Federal Aeronautics Administration (FAA) for use on aircraft. It’s also approved for use on cruise lines, bus lines, and Amtrak. If you have questions about traveling with oxygen, contact us!

One caveat…

If your prescription is above three, this device will not work for you. The highest liter flow of oxygen that it can deliver is three (3 lpm). So, if your physician has been raising your oxygen prescription, you might want to consider a five-liter machine. Take a look at the Inogen One G3 as an alternative.
