Why we like Inogen One G4 as best lightweight
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.
What customers are saying
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.
“The Inogen one g-4 is a fantastic machine, light and powerful, and suits my needs to a tee!”
—James C., Oxygen Concentrator Store reviewer
“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.”

- It’s heavier than other models but has a mobile cart with rolling wheels and a telescoping handle.
Why we like CAIRE SeQual Eclipse as best pulse flow
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.
What customers are saying
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.”

A portable oxygen concentrator draws in air from the surrounding environment, filters out nitrogen and other gasses, and delivers concentrated oxygen to the user. (7) The device contains a compressor pressuring the air, passing through a sieve bed filter system. The sieve bed is filled with zeolite, which attracts and separates nitrogen from the air, allowing the concentrated oxygen to pass through. The oxygen is delivered to the user through a nasal cannula or mask. Portable oxygen concentrators are powered by rechargeable batteries, allowing users to move freely while receiving oxygen therapy. These devices are designed to be lightweight and compact, making them easy to carry and use on the go.
What to consider when buying a portable oxygen concentrator
There are several key factors to consider when buying a portable oxygen concentrator. (8) First, evaluate your oxygen needs and consult your healthcare provider to determine the appropriate oxygen flow rate and delivery method (pulse or continuous flow). 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.
