Inogen One G4 Portable Oxygen Concentrator


Let us introduce the smallest and lightest portable oxygen concentrator on the market, the Inogen G4. It weighs less than 3 pounds and will offer three settings. The Inogen G4 is excellent for both local use and uses while traveling. It can charge in the car or on the wall and can be used simultaneously while charging. This device is also one of the quietest portable units on the market at only 40 decibels. The G4 produces less noise than a usual indoor discussion. This means you won’t disturb others when you use your oxygen concentrator and will feel more comfortable in social settings. The G4 is an excellent option for 24/7 use!



Portable oxygen concentrators no longer have to be a hassle, thanks to the Inogen One G4. The G4 is one of the smallest and quietest packages available. The starter package comes with the Inogen G4 unit, single battery, AC power supply, DC power cable, carrying bag, cannula, and manual. An easy to read LCD screen is provided to detect when breathing is not efficient enough, or the battery is running low. This machine weighs 2.8 pounds and can easily fit into the satchel built for portability. The G4 delivers supplemental oxygen in three settings and offers up to five hours of cordless power with its double battery. Let’s say you’re exercising or physically active; the unit will provide smaller, quick bursts of oxygen to satisfy your energy needs. However, during rest or sleep, the system offers larger oxygen boluses more slowly to correspond with your decreased rate of respiration. This means the G4 can effectively be used during sleep at night, an area where many other portable oxygen concentrators fall short. The ultimate result is to provide a reliable solution for portable oxygen therapy. The G4 is one of the most convenient oxygen concentrators on the market.
