The single battery can last up to six and a half hours on a setting of one, while the double battery can provide up to 13 hours of use. However, the double battery increases the device’s weight by 12 ounces. This extended battery life, combined with the device’s FAA approval, makes it an excellent choice for users who frequently travel or spend extended periods away from home.

We were also impressed by the condenser’s quiet operation, producing only 38 decibels of sound at a setting of two, which is equivalent to a quiet conversation. This low noise level ensures that users can comfortably use the concentrator in social settings without disturbing others.

Another compelling feature is the Inogen Connect mobile app, which allows users to monitor their devices more closely through their Apple or Android smartphones.

While the Inogen One G5 offers numerous benefits, it is more expensive than other portable oxygen concentrators. Additionally, some users may prefer a continuous flow option, which the Inogen One G5 does not offer.

We highly recommend the Inogen One G5 Portable Concentrator for its portability, advanced features, and user-friendly design. Its lightweight build, long battery life, and quiet operation make it a smart choice for users who prioritize mobility and discretion in their oxygen therapy.

Most customers are extremely pleased with the mobility the Inogen One G5 offers them, but some have issues with the noise level at night.

“Inogen One G5 is awesome!” writes Vicki M. on HealthOutletStore. “I have chronic respiratory failure… I have been using my Inogen One G5 for two weeks now. At home, I use the AC cord on battery power outside my home. It is terrific! The pulse mode provides the same O2 as my metal tanks.”

“The Inogen One G5 has been a blessing. Before, I constantly worried about running out of oxygen or facing breathing issues. With this machine’s reliable and consistent supply, I can finally breathe easy. It’s lifted a weight off my shoulders!”

—Zhang W., HealthOutletStore Reviewer

However, some users have found the Inogen noisier than expected and say it doesn’t live up to its price point.

“I just purchased the Inogen 5 after using another brand for six years,” writes Oxygen Concentrator Store shopper Tom. “My old concentrator never had one problem until the very end. It never needed any maintenance. I have had the Inogen 5 for a week. My wife and I couldn’t sleep the first night I used it because of the machine’s popping noise. Inogen told me the noise should disappear after the machine powers up. So they sent me a new machine which does the same thing. After reading the instructions, I noticed that it needs periodic maintenance. For the price, I am not too satisfied.”

Users wanting to take their oxygen concentrator everywhere and anywhere will find a lot to love in Inogen One G4’s incredibly lightweight and compact size.

The Inogen One G4 Portable Concentrator is our top pick for the best lightweight portable oxygen concentrator. Weighing 2.8 pounds with a single battery, the FAA-approved concentrator is incredibly compact and portable, making it ideal for users who prioritize mobility and ease of use.

Our testing proved the G4’s ability to provide efficient oxygen delivery despite its small size. The device utilizes Inogen’s Intelligent Delivery technology, rapidly detecting a user’s breath and delivering oxygen within the first 400 milliseconds. This is a critical feature, as most gas exchange in the lungs occurs during this initial period. By delivering oxygen at the start of a breath, the G4 ensures that the body uses oxygen more efficiently.

The Inogen One G4 proves to be exceptionally quiet, producing only 40 decibels of sound at a setting of 3, quieter than a normal indoor conversation. This low noise level makes it an excellent choice for users who want to use their oxygen concentrator discreetly in social settings or quiet environments.

The G4 offers three pulse dose settings, allowing users to adjust their oxygen therapy based on their needs. The device’s Intelligent Delivery system also accurately detects the user’s breathing rate and adjusts the oxygen level accordingly. During physical activity, the G4 provides smaller, quick bursts of oxygen to meet the user’s increased energy needs. At the same time, during rest or sleep, it delivers larger oxygen boluses more slowly to match the decreased respiration rate. This adaptability allows the G4 to be effectively used around the clock, eliminating the need for separate day and night oxygen systems.

Battery life is crucial for portable oxygen concentrators, and the Inogen One G4 performs reasonably well. The device can provide up to two hours and 40 minutes of use with a single battery, while the extended battery can last up to five hours. While this battery life may be sufficient for many users, those who require longer periods away from a power source may need to consider purchasing additional batteries.

One potential drawback of the Inogen One G4 is its limited oxygen flow settings, which only range from one to three. Some users with higher oxygen needs may require a device with more advanced settings. The G4’s small size may make it more prone to accidental damage if not handled carefully.

The Inogen One G4 is compatible with the Inogen Connect mobile app, which allows users to monitor the device more closely. The app provides information on battery life, column status, cannula life, and more, giving users greater control and peace of mind.

Customers call the Inogen One G4 a “game-changer” because of its lightness and portability. However, some users would like to see more detailed instructions for some of the accessories.

“I’m thrilled to have this unit,” writes “Reviewer” on DirectHomeMedical. “I’ve not been getting out as much as I would have liked because the weight of the other, heavier oxygen concentrator hurt my shoulder and lower back. My insurance would not cover this lighter unit, so I purchased it myself, and [it] was well worth the investment.”

Some users complained about a lack of instructions and difficulty with the power plug.

“The unit is great, but there were no instructions, and the carrying case is a little difficult to manage,” writes Allen at Oxygen Concentrator Store. “The power supply plug-in doesn’t line up with the cutout. Otherwise, we received the unit very quickly…much appreciated.”

We love the CAIRE SeQual Eclipse 5 for its wide range of oxygen settings, long battery life, and mobile cart that makes traveling easier. However, its high price point is a factor to consider.

We chose the CAIRE SeQual Eclipse 5 Portable Concentrator for the best pulse flow portable oxygen concentrator (5) because this powerful device offers a wide range of both continuous flow and pulse dose oxygen settings, making it an excellent choice for users with varying oxygen needs.

Our testers were impressed by the Eclipse 5’s precise dosage capabilities. The continuous flow settings range from 0.5 to 3 LPM in 0.5 increments, allowing users to fine-tune their oxygen therapy. The pulse dose settings are equally impressive, ranging from 16 to 192 mL across nine settings. This level of customization ensures that most users can find the optimal setting for their specific needs.

One of the Eclipse 5’s nice features is its AutoSAT technology, which maintains a consistent level of oxygen delivery even as the user’s breath rate changes. This is particularly beneficial for users who experience fluctuations in their breathing patterns throughout the day or during physical activity. The Eclipse 5 also offers three rise time options (slow, medium, and fast) and three adjustable pulse dose sensitivity settings, enhancing its adaptability to individual users’ needs.

While the Eclipse 5 is one of the heavier portable oxygen concentrators on the market, weighing 18.4 pounds with the battery installed, it makes up for this with its extensive features and settings. The included mobile cart alleviates some of the burden of the device’s weight, featuring smooth-rolling wheels and a telescoping handle for easy maneuverability. The cart can also be folded up for convenient transport and storage. And since it’s FAA-approved, it’s air travel-ready.

Battery life is another area where the Eclipse 5 excels. Depending on the flow setting, the device can provide up to five hours of use with a single battery. This extended battery life allows users to enjoy greater freedom and independence without worrying about constantly recharging the device. Additionally, the Eclipse 5’s battery can be recharged. At the same time, the unit is connected to any heavy-duty DC power supply, such as a vehicle’s power outlet, saving valuable time and ensuring that the device is always ready for use.

One potential drawback of the Eclipse 5 is its noise level, which measures 48 decibels at 3 LPM on continuous flow, comparable to average office noise. However, when using pulse dose settings, the noise level drops to a more comfortable 40 decibels at a setting of three, which is equivalent to a quiet conversation.

Our testing found the Eclipse 5’s upgraded internal system reliable and efficient, providing an average oxygen purity of around 90%. The device’s easy access to the removable battery and contemporary mobile cart design contributed to its user-friendliness.

Users like the efficient pulse oxygen dosing and say it’s improved their mobility, though some say the battery drains quickly at higher settings.

“I had another high oxygen unit that did not work for me, and I returned it,” writes Sue on Oxygen Concentrator Store. “The other high-flow oxygen machine was extremely noisy, whereas this one is quiet. When I take it shopping, I put it in the cart; it is heavy to lift. I am still able to do it. I like this machine, and this is much easier after using big oxygen tanks to go out. It has allowed me the freedom to go on trips again.”

“This device is a very capable POC and a great match for my medical and lifestyle needs. I am thrilled with my regained mobility. Pulse and continuous flows made this the ideal choice for me. I am thrilled.”

Next, consider the device’s size, weight, and battery life, as these factors will impact its portability and ease of use. Look for a concentrator with long battery life and quick recharge time to ensure uninterrupted oxygen therapy while on the go.

Noise level is another important consideration, especially if you plan to use the device in quiet environments or while sleeping. Additionally, check the device’s durability, warranty, and maintenance requirements to ensure it will withstand daily use and provide lasting value. Finally, consider the cost of the device and any ongoing expenses, such as replacement batteries or filters, and check if your insurance covers the purchase or rental of a portable oxygen concentrator.

Portable oxygen concentrators typically cost between $1,500 and $3,500, depending on the model, features, and brand. Some high-end models can cost up to $4,000 or more. Rental options are also available, ranging from $300 to $500 per month.

Yes, Medicare Part B covers portable oxygen concentrators as durable medical equipment (DME) if you meet certain medical criteria and have a prescription from your doctor. Medicare will cover 80% of the approved amount, and you’ll be responsible for the remaining 20% after meeting your deductible. (9)

Yes, there are portable oxygen concentrators that offer continuous flow. However, these models are typically larger and heavier than pulse-flow concentrators. Examples of continuous-flow portable oxygen concentrators include the Respironics SimplyGo, SeQual Eclipse 5, and Ox Life Liberty 2.

Yes, a prescription from a licensed healthcare provider is required to purchase or rent a portable oxygen concentrator. (10) The prescription should specify the oxygen flow rate, delivery method (pulse or continuous flow), and duration of use. This is necessary to ensure you receive the appropriate oxygen therapy for your medical condition.

“Patients with chronic obstructive pulmonary disease (COPD), pulmonary fibrosis, or other respiratory disorders can greatly benefit from using a portable oxygen concentrator,” says Dr. Raj. “These devices offer the freedom to maintain an active lifestyle while ensuring continuous access to necessary oxygen therapy, which is crucial for improving quality of life and managing symptoms effectively.”

Portable oxygen concentrators typically last between three and seven years, depending on the model, usage, and maintenance. With proper care and regular servicing, some concentrators can last even longer. Manufacturers often provide one to five years warranties covering defects and repairs.

The best portable oxygen concentrator type depends on your needs and lifestyle. Pulse-flow concentrators are generally smaller, lighter, and more portable, making them ideal for active individuals. Continuous-flow concentrators are better suited for those who require a constant oxygen supply or have higher oxygen needs. Consult your healthcare provider to determine the best concentrator for your medical condition and oxygen requirements.
