If your doctor has prescribed supplemental oxygen, you may choose a portable oxygen concentrator (POC) or a home oxygen concentrator (HOC), depending on your doctor’s recommendation. A POC, also called a portable oxygen machine, provides safe, effective delivery of oxygen to people with low oxygen levels while they are away from home, according to the U.S. Food and Drug Administration (FDA). You may use a POC while running errands, traveling, or doing other activities outside the house.

Finding the best portable oxygen concentrator for your needs can be confusing—especially if you’re buying one for the first time. Our Reviews Team researched the best POCs on the market to help you choose. We dug into information on pricing, features, battery life, and more to help you find the best model for you.

Inogen One G5

9 Best Portable Oxygen Concentrators in June 2024: Our Expert Picks (5)

9 Best Portable Oxygen Concentrators in June 2024: Our Expert Picks (6)

Price: $2,882

Weight: 4.7 pounds (single battery)

Battery life: Up to 8 hours of battery life (with double battery)

Maximum oxygen output: 1.26 liters per minute (LPM)

Why we chose this machine

The Inogen One G5 is a small, lightweight device with a long battery life. This machine can be worn with a shoulder strap as you walk to and from your flight and is easily stored underneath your seat or by your side on the plane. It is also approved for use on planes by the Federal Aviation Administration (FAA), as is every POC we reviewed.

Pros & Cons

Pros Battery life can range from 6 to 13 hours on the lowest setting The noise level is quiet Cons The double battery adds 12 ounces of weight Only a three-year warranty

Additional details: lightweight with long battery life

Generally, the lower the oxygen output and the longer the battery life, the better the POC is for air travel. If you use a double battery for your G5, you’ll have up to 13 hours of power on Setting 1 and nine hours on Setting 2. The G5 also has a maximum oxygen output of 1.26 liters per minute (LPM) and six different flow settings to suit your oxygen needs.

The free Inogen Connect app is a bonus feature to connect the G5 to your smartphone. You can check the battery life and change your concentrator settings on the app instead of pressing buttons on the machine itself.

A customer review on the Oxygen Concentrator Store said, “I’ve used it one day so far, and all is well with the G5. I chose it because of the longer battery life it has. I was tired of feeling like a prisoner in my home. I wasn’t able to be out for more than 2 hours without carrying extra tanks with me. Now I can do more things with the G5.”

Inogen has an additional brand called OxyGo, selling the same machines under a different name. The Inogen One G5 is the same machine as the OxyGo Next. The cost is the same; the only difference is the OxyGo Next comes with a five-year warranty, and the G5 comes with a three-year warranty.

In late 2023 or early 2024, Inogen plans to rebrand the G5 as the Rove 6 to comply with European regulations. The product won’t change, but the name will.

Check Price 877-428-7356

Why we chose this machine

The CAIRE Freestyle Comfort delivers oxygen for up to 16 hours between charges (with an extended battery), surpassing most other models on the market. This is why our Reviews Team named it “Best Battery Life.” If you enjoy long outings, this unit may be a great fit.

Pros & Cons

Pros The longest battery life of any POC we reviewed Curved design for easy carrying Comfort Zone service program will send a replacement if yours malfunctions Cons The warranty is only for three years Extended battery costs $589 extra

Additional details: leading technology and customer support

Extended batteries add an additional cost to your purchase, but offer longer battery life. With the Freestyle Comfort, it costs an additional $589 for the 16-cell battery. If you purchase the machine and the extended battery, the total cost adds up to $3,584.

A feature making the CAIRE Freestyle Comfort unique is its leading technology. It has ultra-sensitive breath detection, automatically changing the flow to match your breathing rate.

CAIRE’s Comfort Zone service program also sets the brand apart. Comfort Zone includes the following features:

  • Live online orientation with a CAIRE representative to help you set up your machine
  • Customer support seven days a week
  • A replacement POC will be sent to your home within three business days if yours malfunctions

The last point is unique among portable oxygen concentrator companies; no other brand we’ve reviewed provides this type of warranty or service. The replacement device will become your new unit, and the warranty from your older device will transfer over. Comfort Zone is included with the purchase of a CAIRE Freestyle Comfort unit at no extra cost.

The CAIRE Freestyle Comfort can also be purchased as the ARYA Portable Oxygen Concentrator. The machines are the same but sold under different brand names and prices. The Arya POC costs $3,495, while the Freestyle Comfort costs $2,995.

A customer review on the Oxygen Concentrator Store page said, “After spending two days researching for a concentrator replacement with the right balance between weight and battery run time, choosing the CAIRE Freestyle Comfort was easy. And it was a pleasant experience talking to the representative. I now have a smaller unit that easily fits into my walker’s seat compartment and has five output flow levels. Very pleased.”

The Freestyle Comfort is a good device if you don’t want to worry about changing batteries every few hours while out and about. Explore more in our full CAIRE review.

9 Best Portable Oxygen Concentrators in June 2024: Our Expert Picks (10)

Price: $2,500

Weight: 10 pounds

Battery life: 3.4 hours

Maximum oxygen output: 2 LPM

9.6 Excellent

Check Price 877-428-7356

Why we chose this machine

Oxygen needs can change, and you may want a device to accommodate those changes. The Respironics SimplyGo offers both continuous and pulse flow options and up to 2 LPM of oxygen in the continuous flow setting. It has six pulse settings, while most other devices offer three to five. This range gives users flexibility in their oxygen flow if their doctor recommends a change in dose.

Pros & Cons

Pros Six pulse settings Pulse dose and continuous flow Maximum oxygen output is 2 LPM Comes with carrying case and wheeled cart Cons Weighs 10 pounds Battery life is shorter than other machines

Additional details: versatile settings and features

The Respironics SimplyGo offers a portable solution for both pulse-delivered oxygen and continuous flow. It comes with six pulse settings and a high maximum oxygen output. A larger motor brings this device to 10 pounds. That said, it’s one of the lightest continuous flow oxygen concentrators on the market, and its carry case and foldable rolling cart make for easier transportation.

The SimplyGo uses a “sleep mode” to automatically boost oxygen flow while you sleep. It also shows alerts when it detects a low battery, low oxygen purity, no flow, no breath, or a high breath rate. Its concentrator unit has a three-year warranty, while its accessories, like chargers, tubing, and carry cases, have a 90-day warranty.

A smaller alternative to the Respironics SimplyGo is the SimplyGo Mini, a pulse-only model that is half its weight with more than double its battery life. Both devices are designed to function at altitudes up to 10,000 feet and withstand extreme temperatures, vibrations, and impacts.

Price: $2,744

Battery life: 1.2 hours 40 minutes to 5 hours (on Setting 1)

Maximum oxygen output: 0.63 LPM

9.9 Exceptional

Check Price 800-926-0586

Why we chose this machine

The Inogen One G4 (also sold as the OxyGo Fit) is smaller and lighter than almost every other POC on the market, making it our Reviews Team’s pick for the “Most Portable Oxygen Concentrator.” If you’re often on the go and need something easy to carry, this model may be an ideal option.

Pros & Cons

Pros The lightest and smallest concentrator we reviewed Can connect to your smartphone Cons Battery life is shorter than other machines Only three pulse settings to choose from

Additional details: one of the smallest, lightest POCs

Because it’s so small, the G4 is less powerful than other models, with a maximum oxygen output of only 0.63 LPM. The other Inogen model on this list, the Inogen One G5, has an output of 1.26 LPM.

The G4 single battery lasts only about 2 hours and 40 minutes, depending on the setting. If you’re heading out for more than a quick errand, you’ll want to have the double battery or bring an extra one for backup. You also have the option to charge your machine in the car between errands.

You can connect the G4 to your smartphone using the free Inogen Connect app. The app allows you to use your phone to check the battery status and change device settings.

Some customer reviews from the Oxygen Concentrator Store and Trustpilot reported the device can overheat. When our Reviews Team asked a representative at the Oxygen Concentrator Store about this, they said POCs can be susceptible to overheating when the vent is covered up, which can happen if the machine is placed in the carry bag incorrectly or placed too close to another object for a long time. Overheating prevents it from functioning properly, and it may damage the machine. When you place the machine down or in the carry bag, ensure the vent isn’t covered.

Our Reviews Team found most customer reviews from the Oxygen Concentrator Store and Trustpilot on this product were positive. Reviewers praised the device’s light weight, which allows them to run errands with ease. One reviewer from the Oxygen Concentrator Store said, “Within 24 hours, I had the unit in hand, and I was just so excited. I had my freedom again! It has kept my oxygen consistent. I am already looking to get a smaller battery for extra time while I’m out. Being a small person, I don’t think I could carry a much heavier machine.”

CAIRE SeQual Eclipse 5

Highest Oxygen Output

9.7 Exceptional

9 Best Portable Oxygen Concentrators in June 2024: Our Expert Picks (13)

9 Best Portable Oxygen Concentrators in June 2024: Our Expert Picks (14)

Price: $3,200

Weight: 18.4 pounds (single battery)

Battery life: 3.7 hours on continuous, 5.4 hours on pulse (on Setting 1)

Maximum oxygen output: 3 LPM (continuous), 1.92 LPM (pulse)

9.7 Exceptional

Why we chose this machine

The CAIRE SeQual Eclipse 5 has the highest oxygen output of all the portable oxygen concentrators we reviewed. The oxygen output on this machine can go up to 1.92 LPM on pulse flow and 3 LPM on continuous flow, so it can be used while sleeping. It also has nine different settings for pulse flow, allowing users to adjust to their specific dosage.

Pros & Cons

Pros Maximum oxygen output is 3 LPM Comes with a wheeled cart for easy transport Continuous and pulse flow Cons Heaviest portable machine we reviewed Customer reviews reported it might be slightly louder than expected Most expensive POC we reviewed

Additional details: high output with nine pulse settings

Since this concentrator has a high oxygen output, it is bigger and heavier than other devices and cannot be carried in a bag. The SeQual Eclipse 5 is 19.3 inches tall, 12.3 inches wide, 7.1 inches deep, and weighs 18.4 pounds. The device comes with a wheeled cart to make it easier to move around. Some customer reviews on the Oxygen Concentrator Store reported they prefer this machine as they can roll it around on a cart instead of one carried in a shoulder bag.

Customer reviews vary when it comes to the machine’s noisiness: some reported the machine is louder than expected, while others reported it is quieter than other machines they’ve used. The noise level of the SeQual Eclipse 5 varies based on its setting. At 3 LPM on continuous flow, the noise level is 48 decibels—comparable to the noise level of the average office. [2]International Noise Awareness Day. Common noise levels – how loud is too loud? Found on the internet at https://noiseawareness.org/info-center/common-noise-levels/ At the pulse dose setting of 3, the noise level is 40 decibels—comparable to background noise in a library. [2]International Noise Awareness Day. Common noise levels – how loud is too loud? Found on the internet at https://noiseawareness.org/info-center/common-noise-levels/

A customer reviewer on the Oxygen Concentrator Store wrote, “I had another high oxygen unit that did not work for me, and I returned it. The other high-flow oxygen machine was extremely noisy, but this one is quiet. When I take it shopping, I put it in the cart. It is heavy to lift, but I can still do it. I like this machine, and this is much easier after using big oxygen tanks to go out. The [SeQual Eclipse 5] has allowed me the freedom to go on trips again.”

Check Price 877-428-7356

Why we chose this machine

Philips Respironics designed a POC with a clear and simple display screen, making it an excellent choice for anyone looking for a basic unit—especially those purchasing a portable oxygen concentrator for the first time. The touch screen relies on images and easy-to-follow instructions rather than buttons. Its user-friendly design earned the Philips Respironics SimplyGo Mini the title “Easiest to Use” from our Reviews Team.

Pros & Cons

Pros With an extended battery, the unit can last up to 9 hours Can withstand extreme temperatures, vibrations, and impacts Simple screen display with large numbers and pictures Cons Loudest pulse-flow portable oxygen machine in our review Extended battery costs $500

Additional details: durable with a long battery life

While the Philips Respironics SimplyGo Mini is a quiet machine, it is louder than other pulse-flow portable oxygen concentrators on this list. At 43 decibels, it is 3 decibels louder than the Inogen One G4. For reference, a refrigerator humming is about 50 decibels. [2]International Noise Awareness Day. Common noise levels – how loud is too loud? Found on the internet at https://noiseawareness.org/info-center/common-noise-levels/

With the standard battery, the device can last up to 4.5 hours. You can purchase an extended battery to give your device up to nine hours of run time, but it does cost an additional $500 at the Oxygen Concentrator Store. The device comes with a carry bag.

If you’re interested in this brand but need continuous flow oxygen, you might want to check into the Philips Respironics SimplyGo. At 10 pounds, it’s heavier than the SimplyGo Mini, but it offers both continuous and pulse flow settings and comes with a rolling cart.

The SimplyGo Mini is an easy-to-use portable oxygen concentrator able to tolerate accidental drops or falls. Read more in our full Philips Respironics review.

Maximum oxygen output: 0.78 LPM

9.2 Excellent

Why we chose this machine

When purchasing an oxygen concentrator, you want a reliable machine able to work for years to come. Even though there’s no way to know for sure how long a device will last, you can ensure the POC you purchase has a warranty covering any damage or issues. The Precision Medical EasyPulse comes with a five-year warranty (the other POCs we reviewed come with three-year warranties). The EasyPulse is a great choice for those looking for extra protection to cover their POC.

Pros & Cons

Pros Most low-cost POC we reviewed Five pulse settings Five-year warranty Cons The heaviest pulse dose machine on our list Oxygen output isn’t as high as other POCs

Additional details: low price, long warranty

The EasyPulse has a user-friendly design with large, easy-to-read buttons and a top handle to move it from place to place when not in its carrying case. The maximum oxygen output is 0.78 LPM, which is lower than other machines on this list.

This machine is the heaviest pulse dose machine in our review, weighing 6.6 pounds. If you are looking for a smaller device, the EasyPulse is available in a 3-liter option weighing 4.9 pounds and ranges in cost from $975 to $1,118. The cost varies with either machine depending on if you purchase a backpack or an external battery.

The 3-liter machine has three pulse settings, while the 5-liter machine has five settings. The 5-liter machine is quieter than the 3-liter machine (40.6 decibels compared to 42 decibels). On Setting 1, the 3-liter device has a battery life of 5.5 hours, and the 5-liter machine has 4.7 hours.

Customer service

The EasyPulse POC is available for purchase online through the Precision Medical website. Precision Medical doesn’t have any reviews on Trustpilot or BBB. Our Reviews Team found it very difficult to reach customer service. When we contacted them through the contact form, we never received a reply.

9.3 Excellent

Check Price 877-428-7356

Why we chose this machine

Our Reviews Team chose the Invacare Platinum Mobile as our “Most Durable” POC because this solid machine can resist impact and endure accidental falls. The Platinum Mobile is encased in shock-resistant foam with reinforced bumpers for added protection. In addition to being water resistant, the machine can tolerate temperatures from 41 to 104 degrees Fahrenheit and altitudes up to 10,000 feet.

Pros & Cons

Pros Water resistant and can withstand up to 10 minutes of rain Carrying case converts to a backpack and purse-style bag Cons Only four pulse settings A single battery only provides four hours of use

Additional details: durable and water resistant

One of the benefits of the Invacare Platinum Mobile is the carrying bag, which can convert into a backpack, messenger bag, or purse. The machine is also lightweight, weighing 4.8 pounds.

The battery compartment is located at the top of the device, making it easy to access on the go without having to remove it from the carrying case. The Invacare Platinum Mobile comes with a single battery, providing up to four hours of charge. If you anticipate being out of the house for longer than four hours, you can purchase an additional battery, giving you eight hours of running time on Setting 1.

A customer review on the Oxygen Concentrator Store stated, “I travel a lot internationally, and a year ago, I realized I had been suffering from high-altitude pulmonary edema for years. Now, with my oxygen concentrator, I get off a long flight feeling great and ready to go. No more international doctor visits. It’s never overheated, and some airlines let me plug in. It’s been awesome.”

9 Best Portable Oxygen Concentrators in June 2024: Our Expert Picks (22)

Price: $2,310–$2,562

Weight: 5 pounds (single battery)

Battery life: 6.5 hours (on Setting 1)

Maximum oxygen output: 1 LPM

9.2 Excellent

Why we chose this machine

The Precision Medical Live Active Five has a unique curved design, separating it from other POCs we reviewed. Some POCs are designed with a curve to fit around your body in the carry bag. But the Live Active Five is curved on both sides of the machine, so you can carry it on either side of your body. The device is lightweight, but if it does become too heavy for one shoulder, you can switch it over to the other.

Pros & Cons

Pros Five pulse settings Double-curved design for added comfort Easy-to-read screen Cons No customer reviews on the product No backpack option available

Additional details: comfortable and affordable

In addition to the curved features, the Live Active Five has a simple design with few buttons and an easily read LCD screen featuring large text. You can access the battery from the top of the device, so you do not need to take it out of the carrying case when changing the batteries.

As a bonus feature, you can also connect the machine to a computer or smartphone through Bluetooth to troubleshoot the unit if you encounter any problems. The Live Active Five has audible and visual alarms if there are problems like:

  • Low battery
  • Blocked cannula
  • Low oxygen purity
  • No breath detected
  • High breath rate
  • External power failure

If the machine doesn’t detect your breath, it will automatically deliver a pulse of oxygen. The Live Active Five also has five pulse settings and a maximum oxygen output of 1 LPM.

Customer service

The Precision Medical Live Active Five is sold through the Precision Medical website and online distributors like Vitality Medical.

Vitality Medical has a good score on Trustpilot—4.4 out of 5 stars based on over 35,000 reviews. On BBB, Vitality Medical has an A+ rating and 1.4 out of 5 stars based on 46 customer reviews. Reviewers reported the buying experience was quick and easy, and customer service representatives were prompt, professional, and friendly.

Our Reviews Team’s customer service experience

A member of our Reviews Team called the Oxygen Concentrator Store to learn more about the brands and models in this list. It took less than 30 seconds to get a representative on the line. He was friendly, helpful, and knowledgeable about every model we asked about.

He informed us all portable oxygen machines sold through the Oxygen Concentrator Store come with a free seven-day trial period. If you find the unit you’ve purchased has mechanical problems, is hard to use, or just isn’t a good fit for you, simply call the store to receive a shipping label. Then, you can send the unit back (at your own cost) and exchange it for a different one.

Shipping takes about three to five business days, but Oxygen Concentrator Store also offers two-day and overnight shipping for an additional cost.

After sharing details of the various models over the phone, the representative offered to email us the information and gave us his direct phone number for any future questions. He also said even if we didn’t buy a unit from the Oxygen Concentrator Store, he would be happy to answer questions and provide help in the future. We were very pleased with the customer service experience; it felt like we were learning about portable oxygen concentrators rather than enduring a high-pressure sales call.

What is a portable oxygen concentrator?

People with lung issues, such as sleep apnea, COPD, and cystic fibrosis, may use a portable oxygen concentrator as a means of inhaling supplementary oxygen when they are away from home. These machines are typically lightweight and small, making them easy to transport.

Portable oxygen concentrators provide supplemental oxygen by removing oxygen from the air, compressing it, and removing the nitrogen. After that, the oxygen is stored in a tank where it can be delivered through a tube for breathing.

How does a portable oxygen concentrator work?

Oxygen concentrators take in air from the environment, filter out nitrogen, and deliver oxygen to the person using the device. [1]U.S. Food and Drug Administration. Pulse oximeters and oxygen concentrators: What to know about at-home oxygen therapy. Found on the internet at https://www.fda.gov/consumers/consumer-updates/pulse-oximeters-and-oxygen-concentrators-what-know-about-home-oxygen-therapy The oxygen is usually delivered through a cannula sitting beneath the nose. These devices are different from oxygen tanks because oxygen concentrators use electrical pumps to concentrate oxygen from outside, according to an article in the journal Breathe. In contrast, oxygen tanks have a set amount of oxygen stored inside the container requiring the tanks to be replaced with another filled container when empty. [3]Hardavella G, et al. Breathe. September 2019. Oxygen Devices and Delivery Systems. Found on the internet at https://breathe.ersjournals.com/content/15/3/e108

Found on the internet at https://www.lung.org/lung-health-diseases/lung-procedures-and-tests/oxygen-therapy/getting-started-portable-oxygen-concentrator

Oxygen flow types

Portable oxygen concentrators deliver either a continuous flow of oxygen, measured in liters per minute, or a pulse flow (also called intermittent flow). Pulse flow delivery systems give a puff of oxygen every time you breathe.

Some concentrators can deliver oxygen by both pulse or continuous flow, depending on the setting your doctor prescribes. Other devices only provide one type of flow. Most portable concentrators offer only pulse flow settings.

9 Best Portable Oxygen Concentrators in June 2024: Our Expert Picks (23)

When buying a portable oxygen machine, it’s important to know which type of flow you need and the amount of oxygen (in LPM) you’re prescribed. If you’re unsure of these details, check with your health care provider.

Who should use a portable oxygen concentrator?

If you need supplemental oxygen—also known as oxygen therapy—you’re not alone. The American Thoracic Society estimates 1.5 million adults in the United States use oxygen therapy. [5]Jacobs SS, et al. Annals of the American Thoracic Society. December 2018. Optimizing Home Oxygen Therapy: An Official American Thoracic Society Workshop Report.

Things to consider before you purchase a portable oxygen machine

Before you purchase a POC, you should consider different factors to decide which model is the best for your needs.

  • Your current and future oxygen needs: Check your prescription to see what your doctor has written for oxygen amount and flow type. You may also want a machine with an adjustable oxygen output in case your oxygen needs change.
  • Battery life: Consider how long you’ll need to use your POC when you leave the house or if you plan to go on long trips.
  • Warranty length and type of coverage: Warranties vary among manufacturers of portable oxygen concentrators, both in terms of length and what they cover. Make sure you find out specific information on the warranty before you purchase.
  • Size and weight: You may need a small, lightweight machine if you can only carry a few pounds at a time. While most machines come with a carry bag or rolling cart, you may need to move it without the bag or cart from time to time.
  • Noise level: All POCs create sound as they convert air to medical-grade oxygen. Typically, the noise level is about the same as a room with background noise, around 45-50 decibels. But some oxygen concentrators are quieter than others. For instance, the CAIRE Freestyle Comfort only emits about 38 decibels of sound.
  • Buying vs. renting: Determining whether you should buy or rent your POC depends on your needs. Those who only temporarily require oxygen therapy or don’t want to deal with maintenance or repair costs may benefit from renting their device. While buying may be the best option for long-term needs.
  • Cleaning and maintenance: All POCs should be wiped down daily as part of a regular care routine. Some devices need more maintenance than others, requiring regular filter changes or deeper cleaning. Before purchasing, look into your device’s maintenance guidelines to determine if you can keep up with its care.
