With many options to choose from, choosing the right oxygen concentrator can be difficult — especially when you don’t know where to start. Your doctor will decide how much oxygen you need, but not necessarily the exact concentrator system you will buy. It’s up to you to choose an oxygen concentrator that has the features you’re looking for and matches your lifestyle.

That’s why we’re highlighting two of Inogen’s portable oxygen concentrators, the Inogen One G5 and the Inogen One G3. Once you understand what each concentrator has to offer and assess your individual needs, you can decide which machine is best for you.

Inogen One G3 vs. Inogen One G5 Flow Settings

Both the Inogen One G3 and the Inogen One G5 are pulse dose oxygen delivery systems and are built with Inogen’s Intelligent Delivery Technology. This technology ensures oxygen is delivered within the first 400 milliseconds of inspiration (when you breathe in) — when oxygen has the most effect on lung gas exchange.

The G3 and G5 differ in the range of oxygen flow settings offered. The Inogen One G3 has five different flow settings, while the newer Inogen One G5 offers six. The flow settings you’ll need will be determined by your doctor.

Weight and Size

The G3 and G5 are both compact and lightweight (both under 5 pounds), making them easy to carry and solid candidates for those in need of a portable oxygen concentrator.

With a single (8-cell) battery, the G3 model weighs 4.9 pounds, and it is about 8.75 inches wide, 3.26 inches deep, and 8.25 inches tall. The G5 model is slightly smaller, weighing in at 4.5 pounds and 8.15 inches tall, 7.19 inches wide, and 3.26 inches deep.

Battery Life

Battery life is an essential factor to consider when choosing a portable oxygen concentrator, as is the length of time it takes to charge the unit. You need the battery life of your oxygen delivery system to match your lifestyle; you don’t want to be worrying about recharging your unit if you’re constantly out-and-about, traveling, or running errands.

Battery life for both the Inogen One G3 and the Inogen One G5 will depend on which pulse dose setting they’re being used on and which battery is attached (the single 8-cell or the double 16-cell).

The Inogen One G3 has a battery life of approximately 4 hours with the single battery or 8.5 hours with the double battery (on a setting of 2). The Inogen One G5 has one of the longest battery life of a portable concentrator on the market today; it can last up to 4.5 hours with the single battery and 9 hours with the double battery (on a setting of 2).

The Final Choice: Inogen One G5 vs. Inogen One G3

The compact and lightweight design of Inogen’s G3 and G5 portable concentrators makes either an ideal POC for travel, errands, walks around the block, and trips around town. They are similar in size and weight, and are both made with the state-of-the-art technology Inogen’s oxygen concentrators are known for.

Whether the G5 or G3 is the right oxygen concentrator for you will depend on the length of battery life you’re looking for and the pulse settings and oxygen concentration you need. With a longer battery life and the highest oxygen output per pound of any portable concentrator, the Inogen One G5 is a great POC solution for people leading active, busy lives, and those who love to travel or be on-the-go.
