After several weeks of searching fruitlessly for a portable oxygen concentrator, we found Inspired Portable Oxygen. Right from the start, Todd M. was a pleasure to work with. He explained in simple terms how the equipment worked and how each model compared to the others. In the end, we had our unit within a week. It met all of our needs: size, weight, noise level, pulse settings, and battery time. And it was at the most reasonable price.
Tom H.
Tom H.I highly recommend Inspired.
I enjoyed our personable conversations and all the patience you showed me during the entire process of ordering. It took me some time but you were so helpful and truly helped guide me through everything. Thank you for contacting my doctor's office. Now that summer is here, I'm excited to get my new system and get back outside more.

Inogen g4 Portable Oxygen System Makes Life Simpler!

Feeling tethered to a stationary oxygen concentrator can certainly transform your life. Things that were once a breeze, like leaving your home to run errands or play with the grandchildren suddenly become more challenging. And longer trips like family vacations seem nearly impossible. The Inogen One G4 portable oxygen system empowers you to live your life on the go.

Key Features of the Inogen One G4

Lightweight & Compact

The Inogen One G4 is Inogen's lightest portable oxygen concentrator, weighing just 2.8 pounds (with battery). It also comes with a custom case and strap so you can carry your device and take it anywhere!

Noticeably Quiet

At just 39 decibels, you'll notice a difference in the G4's volume compared to other portable oxygen concentrators on the market.

Intelligent Delivery Technology

With 3 oxygen settings the G4 Portable Oxygen System features Inogen's Intelligent Delivery Technology, which allows the respiratory rate to be sensed and adjusted quickly to deliver smaller, faster puffs of oxygen during activity, or slower, larger boluses of oxygen during sleep or rest.

Easy to Use

Flow rate adjustment is easy with a button on the top panel and an easy-to-read LCD display, so you can be confident the device is meeting your oxygen needs.

Monitor Activity Through Your Smartphone

Bluetooth capabilities combined with the Inogen Connect app provide the ability to monitor your Inogen One more closely through any Apple or Android-supported device.

Travel-Friendly

The G4 portable oxygen concentrator is safe and approved by the FAA for all commercial air travel, allowing you to take it anywhere.

Who can Use?

The Inogen One G4 seems to be one of the more appealing portable oxygen concentrators on the market. Enough oxygen production and enough battery life for some people. The Inogen One G4 is perfect for people who mostly travel around town or travel by car or RV. This way the shorter battery life isn't an issue as it can be recharged quickly.

Here at Inspired Portable Oxygen, we recommend the Inogen One G5 if you fly frequently or your oxygen requirement is 3 liters or higher. View G5 HERE.

How much does the Inogen One G4 weigh?

The G4 weighs a only 2.8 pounds with the Single Battery and only 3.3 Pounds with the Double Battery.

Can I use insurance to purchase a G4 unit from Inspired Portable Oxygen?

No. Typically, Insurance doesn’t purchase portable concentrators. Insurances may pay a rental fee for medical equipment and supplies only if a supplier has a Medicare or Medicaid supplier number. Inspired Portable Oxygen, the operator of this website, does not have a Medicare or Medicaid supplier number. Insurance will not pay for any medical equipment and supplies we sell to you.

Is financing available for the G4?

Yes, We do offer easy financing with approved credit. Please give us a call to discuss which package works best for you and we will help you get started on the simple financing application.

Will the Inogen G4 work for me?

Depending on your oxygen prescription, it’s likely that it will! The most common prescription for oxygen is 2-3 liters per minute, and the G4 can deliver that amount of oxygen using intelligent pulse dose delivery. The Inogen One G4 portable oxygen system is available by prescription only. If you have been prescribed oxygen, there is a good chance that the FIT System will work for you. We offer a 30 Day Risk Free trial, too!

Can I fly with G4?

Yes! The G4 can go where you go. The G4 portable oxygen concentrator complies with the applicable rules and regulations for domestic and international air travel. Each G4 machine has a label on the back indicating it is FAA Approved.

I'd like to get a loved one an Inogen G4. How do I do that?

If your loved one is on oxygen, there is a good chance Inogen will work for them! You can purchase a G4 or any other model to own and we will help you get the necessary doctor’s Rx.

My current oxygen equipment provider said they cannot assist me in getting a G4 portable. What should I do?

Because most oxygen equipment companies are dealing with Medicare and Insurance constraints, the G4 is not offered from most medical equipment companies. This is the main reason we are a discount retailer and why we assist so many oxygen users. You can purchase a new system from us, at a huge discount, and still keep your current oxygen equipment you may be getting through insurances.

How much does the Inogen One G4 cost?

Cost depends on which package you choose. You may want a system with one battery, or two. You may want to upgrade your warranty on the G4 device. We offer Exclusive G4 freedom/sale packages with discounts up to 60% off Inogen’s Suggested Retail Price.
