Inogen One G3 System

Talk to Your Insurance Provider for Costs

Features:

  • Accommodates double battery
  • Single battery included
  • AC/DC power
  • Carry bag included
  • Auto-sensing power supply for use worldwide
  • Up to 4 flow settings
  • Intelligent Delivery Technology
  • Never needs a refill
  • FAA approved

The Inogen One G3 System is a basic, portable oxygen concentrator available for insurance rental only. If you’re experiencing a temporary condition where you need oxygen therapy, your insurance may cover the rental fee to help you through recovery.

The G3 is relatively lightweight at only 4.8 pounds. Though it isn’t the lightest portable oxygen concentrator in Inogen’s line, it’s easy to carry around for most adults and seniors. It has dual-battery capabilities and also has AC/DC power for stationary use. With a single battery, the concentrator can last about 4.7 hours, and up to 10 hours with two batteries. The G3 offers four different oxygen flow settings, so you can adjust the amount of oxygen you’re getting for optimal comfort. For on-the-go use, the concentrator comes with a single battery and carry bag.

If you’re interested in using the G3, you’ll need a doctor’s prescription for oxygen therapy. From there, Medicare or your private insurance can cover up to 80% of the rental cost. Inogen can work with you and your insurance company to determine your eligibility and make sure you have the proper paperwork for insurance coverage.

Inogen One G4 System

$2,795

Features:

  • Accommodates double battery
  • Single battery included
  • AC/DC power
  • Carry bag included
  • Auto-sensing power supply for use worldwide
  • Up to 3 flow settings
  • Intelligent Delivery Technology
  • Inogen Connect mobile app
  • Never needs a refill
  • FAA approved

Like the G3 system, the G4 is built for portability and oxygen therapy on the go. The G4 is only 2.8 lbs, making it the most lightweight model in Inogen’s line of oxygen concentrators. You will have peace of mind about your health and safety, no matter where you are.

The G4 has dual battery capabilities, though it only comes with one battery. You can purchase an extra battery or double battery through the Inogen site. With one battery you’ll get about 2.7 hours of use, while two batteries can give you 5 hours. Inogen’s battery life estimates are based on continual use while on the second oxygen flow setting. The G4 has three different settings, so battery life may vary for the first or third flow setting.

The G4 also has Bluetooth connection to the Inogen Connect mobile app. Through the app, you can monitor your concentrator’s battery and column life. The columns convert normal air to medical-grade oxygen, so it’s essential to monitor and replace them as needed.

Like all of Inogen’s oxygen concentrators, you’ll never have to worry about filling the Inogen with oxygen. Inogen’s Intelligent Delivery Technology works to convert air to oxygen immediately, delivering you oxygen wherever you need it. Plug into AC power for at-home use, or use the concentrator’s DC power outlets while you’re in the car.

Inogen One G5 System

$3,295

Features:

  • Accommodates double battery
  • Single battery included
  • AC/DC power
  • Carry bag included
  • Auto-sensing power supply for worldwide use
  • Up to 6 flow settings
  • Intelligent Delivery Technology
  • Inogen Connect mobile app
  • Never needs a refill
  • FAA approved

The Inogen One G5 System offers the longest battery life, most quiet machine, and most flow settings out of any other Inogen One product. You can enjoy up to 13 hours of portable use, six flow settings, and only 38 decibels while the machine is running. For comparison, a quiet library is usually still around 40 decibels of noise.

Like the G4 system, the G5 connects wirelessly to the Inogen Connect app to monitor battery life and product health. Like all of the products in the Inogen One line, the G5 meets all FAA regulations allowing you to travel hassle-free and without worrying about your health.

The Inogen One G5 comes with a three-year limited warranty, which covers some repairs and replacements. Similar to the other Inogen One systems, your purchase will include a single battery, carry bag, and AC/DC power cords. At the Inogen site, you can find additional G5 replacement products and accessories to make sure you’re getting the most out of the product. Inogen offers a G5 backpack, external battery charger, particle filter, and more.

Inogen At Home

$1,795-$2,195

Features:

  • AC power
  • 100W energy usage
  • Continuous flow
  • Up to 5 flow settings
  • Auto-sensing power supply for worldwide use
  • Stationary use

The Inogen At Home is Inogen’s stationary oxygen concentrator. While it’s heavier than Inogen’s portable options, it’s still only 18 lbs – light enough to move throughout your home as needed. The At Home model is larger than the Inogen One concentrators, but it’s still just as quiet at about 40 decibels.

One way the At Home concentrator differs from other Inogen One models is that it offers continuous flow, which means that you’ll receive 5 liters of oxygen per minute, whether you’re inhaling or exhaling. You can switch between five different flow settings to optimize your oxygen flow and adjust for comfort.

Though the At Home concentrator uses AC power, it will hardly affect your utility bill. The concentrator only uses about 100W of energy, making it a very efficient option for ongoing oxygen therapy.

The Inogen At Home does not come with a carry bag, though it does include one cannula. The At Home also doesn’t offer Bluetooth connection to the Inogen Connect app, but the user manual can help you prepare for care and maintenance.

With Inogen At Home, you can choose from a three-year or lifetime warranty depending on how often you think you’ll be using the concentrator and for how long.

Inogen Freedom Bundle

Features:

  • One Inogen One model
  • One Inogen at Home model
  • Portable and at-home use
  • Consultation with oxygen specialist
  • Carry bag for Inogen One included
$3,495-$3,865

True to its name, Inogen offers Freedom Bundles to help you live your life just as you normally would, whether you’re using oxygen therapy or not. If you’re looking for long-term use out of your oxygen concentrator as well as portable and stationary use, the Freedom Bundle will give you the best deal.

Extras

Inogen offers a variety of features and extra services to help you customize your oxygen therapy. The add-ons are best for users who are looking for long-term use out of their systems and want to make the most out of Inogen’s products.

Inogen offers oxygen specialists who can work with you and communicate with your physician to determine the best system for your condition if you’re having trouble deciding what you need.

 

Inogen Connect

Inogen Connect is Inogen’s proprietary mobile app. Using Bluetooth technology, the Inogen One G4, and Inogen One G5 seamlessly report battery life, column life, and usage.

Oxygen concentrators are a significant investment, and the Inogen Connect app allows you to maintain your system properly for its best performance. If you’re usually very active, the app can also give you peace of mind knowing exactly how much battery you have left and when it’s time to charge the concentrator.

As an added bonus, Inogen Connect users also receive exclusive discounts through the app to purchase parts and accessories at a discount.

 

Parts and Accessories

Chances are, you’ll be using your oxygen concentrator for months or years to come. It’s essential to customize your system to your needs. Doing so can bring you more comfort and make your oxygen therapy as easy as possible.

Inogen offers replacement accessories like power cords, batteries, and columns. The company makes it easy to find what you need online according to the model you own. You can also customize your experience by purchasing add-on accessories like backpacks, hip bags, battery chargers, and filters.

 

Intelligent Delivery Technology

All of the concentrators in the Inogen One line use a proprietary Intelligent Delivery Technology to optimize oxygen delivery at all hours of the day. These products don’t offer continuous flow like the Inogen At Home. Instead, the Intelligent Delivery Technology optimizes airflow depending on respiration.

At night, when most people take more shallow and limited breaths, the technology allows the devices to deliver more oxygen per breath. The same concept applies if you’re just resting or exerting a lot of physical activity.

Through Inogen’s Intelligent Delivery Technology, you can count on the oxygen you need for the best comfort.

 

Customer Support

Whether you’re a new or prospective customer, it’s clear that Inogen places a big emphasis on making it easy to choose and use their products.

Before you even make a purchase, Inogen makes their oxygen specialists available through phone or email. You’ll receive a quick response to ask questions and understand which system is best for you.

Each Inogen system automatically comes with a full user manual, which you can additionally access online or through the Inogen Connect app. Furthermore, you can access product setup tutorials online. The quick videos take you through the entire process of unboxing your products, putting them together, and adjusting the settings to meet your needs.

If you have additional questions or concerns, Inogen customer support specialists are available seven days a week.

 

Costs

Inogen offers prices that are average for the rest of the industry. However, its Freedom Bundles offer exceptional savings for buying two systems at the same time. Throughout the year, you can enjoy savings off each system’s regular prices. Currently, the Inogen One G4 and G5 are both on sale at close to 20% off. If you can’t afford a one-time payment, Inogen will also work with you to offer monthly financing.

Inogen’s parts and accessories may seem like a way to spend even more money, but they’re only there to enhance your experience. With either system you choose, Inogen offers everything you need from batteries to carry bags.

 

What Customers Say

Inogen’s customers give the company exceptional ratings for its high-quality products that improve mobility and freedom. Overall, Inogen’s customer testimonials include stories about reclaiming their independence. Many customers were able to do things they didn’t think would be possible, such as extended traveling. It’s easy to forget the concentrator is even there with accessories like the hip bag or backpack and Inogen’s Intelligent Delivery Technology.

As with any product, there’s always a small chance that you’ll receive a damaged or defective product. Some customers received concentrators that didn’t last as long as promised or didn’t work altogether. In response to these scenarios, Inogen takes a proactive approach to offer extended warranties and fast repairs or replacements.
