Inogen One G3 Portable Oxygen Concentrator
Inogen is one of the most recognizable names in the oxygen industry and the Inogen One G3 is a big reason why. Weighing in at 4.8 pounds and offering up to 8 hours of battery life, the Inogen One G3 has been one of the most popular portable oxygen concentrators on the market for over two years!
Small, Lightweight, and Durable Design
One of the reasons the Inogen One G3 is so popular is because of its size. Standing just 7.25” W x 3” D x 8.75” H and weighing 4.8 pounds with the 8-cell battery, the G3 is easy to carry wherever you go.
Whether you’re going on vacation, heading to the doctor, exercising, or lounging around your house you will be able to comfortably carry your Inogen One G3 wherever you need to go. Even with the 16-Cell battery, the G3 weighs less than 6 pounds!
One of the other major reasons why the Inogen One G3 is one of the most popular units on the market is the fact that it is one of the most durable and reliable concentrators available. But we will touch more on that later!
High Oxygen Flow
The Inogen One G3 is a pulse flow portable oxygen concentrator. It does not have the ability to provide a continuous flow. It offers pulse flow settings 1-5 and can accommodate nearly any oxygen patient who can use a pulse flow.
A lot of respiratory diseases are progressive in nature. So if you require a setting of 2 or 3, the Inogen One G3 provides you with some wiggle room for an increase in your flow rate. So if your flow rate increases you won’t have to worry about getting a new oxygen concentrator.

Intelligent Oxygen Delivery
Despite the fact that the Inogen One G3 is a pulse flow portable oxygen concentrator, the majority of oxygen patients can still use this machine for nighttime oxygen delivery! Just like the Inogen One G2, the G3 is equipped with Intelligent Delivery Technology.
Inogen’s Intelligent Delivery Technology ensures that your oxygen is delivered within the first 400 milliseconds after your concentrator detects your breath. This almost guarantees that you’re receiving the entire bolus dose of oxygen delivered by your G3.
Along with delivering oxygen within the first 400 milliseconds, the Intelligent Delivery Technology responds to your breath rate! This feature is what allows you to use your Inogen One G3 while you sleep even though it doesn’t offer a continuous flow.
When you are sleeping your breathing rate decreases. As the Intelligent Delivery Technology monitors your breath rate, it will automatically increase or decrease the amount of oxygen per bolus dose depending on the oxygen setting and your breath rate.
For example, if you are breathing at a rate of 10 breaths per minute the Inogen One G3 will double the amount of oxygen per bolus dose than if you were breathing at 20 breaths per minute. This is to ensure you are getting your required oxygen.
One of the big reasons pulse flow portable oxygen concentrators aren’t recommended to use at night while you sleep is that they don’t detect mouth breaths. The Inogen One G3, on the other hand, will be able to detect shallow mouth breaths! So as long as you don’t need a CPAP or BiPAP machine at night, the Inogen One G3 should work for your nighttime oxygen delivery system.
Using the Inogen One G3 is simple and straightforward. The control panel is equipped with an easy to read LCD screen and large push buttons.
The LCD screen shows you vital information like the flow rate you have the machine set to and your remaining battery life. If you are having a hard time reading the screen you have the option of turning the LCD screen backlight on or off.
There are a total of 5 buttons and each push button is labeled with its specific function:
- Power Button (standard power symbol)
- Display Backlight Button (lightbulb)
- Audible Alarm Button (bell)
- Flow Rate Up Button (plus sign)
- Flow Rate Down Button (minus sign)
Amazing Battery Life
One of the most important features our patients look for in a portable oxygen concentrator is the battery life. And it’s easy to understand why… More battery life equals more freedom and independence.
With the Inogen One G3, you have 2 different battery options to choose from:
- 8-Cell Battery
- 16-Cell Battery
The 8-Cell battery keeps your Inogen One G3 at 4.8 pounds and supplies you with up to 4 hours of battery life. It’s perfect for quick errands, doing things around your house, gardening, or exercising.
The 16-Cell battery adds about a pound of weight to your Inogen One G3, but it supplies you with double the battery life. When you think about it, adding an extra pound of weight to get up to 4.5 additional hours of battery life is a pretty good deal!
The 16-Cell battery is ideal for things like traveling, long trips away from your house, and using as a backup power source in case of a power outage.
Here is a chart showing you the expected battery life for every setting on your Inogen One G3:
|Flow Rate||8-Cell Battery||16-Cell Battery|
|1||Up to 4.5 Hours||Up to 9.5 Hours|
|2||Up to 4.0 Hours||Up to 8.5 Hours|
|3||Up to 3.0 Hours||Up to 6.0 Hours|
|4||Up to 2.0 Hours||Up to 4.0 Hours|
|5||Up to 1.7 Hours||Up to 3.3 Hours|
Multiple Carrying Options
Being comfortable when carrying your oxygen is a must! The Inogen One G3 comes with a custom carrying case that makes wearing your O2 as comfortable and easy as possible.
It is equipped with a padded shoulder strap to prevent it from digging into your skin after extended periods of use. It is also equipped with a comfortable handle strap so you can carry your G3 different ways!
One of the more popular accessories for the G3 is the custom backpack. It is designed specifically for the G3 with room for some accessories and personal belongings. Although it’s not included in the standard package, if you are looking to remain active with your Inogen One G3 the backpack is a must-have accessory!
Convenient Charging Methods
Charging your Inogen One G3 is possible virtually anywhere you go! In your package, you will get the AC power supply to use at home and the DC power supply to use on the go! The G3 also has an optional external battery charger available.
AC Power Supply
The AC power supply is equipped with a 110v power cord allowing you to plug it into any wall outlet. Whether you’re at your hotel on vacation, on a cruise ship, or at home you can find a wall outlet nearby and recharge your battery.
When your Inogen One G3 is plugged into the AC power supply your battery will recharge on all 5 oxygen settings. Not only will the AC power supply recharge your battery on all 5 settings, but it will power your concentrator to ensure your battery is ready to use when you unplug it.
If you are using the Inogen One G3 for your oxygen while you sleep, the AC power supply will keep your concentrator running all night long! However, we recommend keeping your 16-cell battery installed in the unit just in-case there is a power outage overnight. The battery will act as a backup power source.
DC Power Supply
The DC power supply is equipped with a 12v power cord. Whether you’re road-tripping across the country, taking a trip to the store, or spending a day on the lake you can plug your Inogen One G3 into the cigarette lighter or 12v outlet in your car, truck, RV, or boat!
When your Inogen One G3 is plugged into the DC power supply your battery will being to recharge and your concentrator will run off of your vehicle’s battery on all 5 oxygen settings. Before plugging your G3 into the DC power supply, make sure that your vehicle is turned on to prevent a blown fuse and to prevent you from draining your vehicle’s battery.
External Battery Charger
The external battery charger is probably the most convenient option to recharge your batteries. Not to mention it recharges your batteries faster than any other method. Instead of having to plug your Inogen One G3 into a power supply, you can simply connect a battery to the external battery charger and continue to go about your day. Because you aren’t using your concentrator at the same time you are recharging your battery it will recharge faster.
The Inogen One G3 external battery charger is equipped with a 110v power cord and can recharge one battery at a time. It’s ideal for patients who have more than one battery, are getting ready for a trip, or those who don’t want to be tethered to a power supply while their battery recharges.
Expected Recharge Time:
- 8-Cell Battery: 2-5 Hours
- 16-Cell Battery: 4-10 Hours
Easy to Maintain
Maintaining your Inogen One G3 is simple and easy to do. There are only two regular maintenance things you will need to worry about:
Depending on how often you use your Inogen One G3 you will need to wash your particle filters. So every week or two here’s what you will do:
- Turn your concentrator off and remove your filters
- Wash your filters in warm water with mild soap
- Let them air dry
- Put them back in
This process should take 5 minutes at most. If you’re worried about going without oxygen we recommend having 2-3 sets of filters that you rotate through. That way you can simply swap them out without having to turn your oxygen off.
Every 6 months to a year you may want to replace your filters.
