Key Takeaways

  • Portable oxygen concentrators are a great option for anyone in need of oxygen therapy and looking to maintain independence and mobility.
  • As regulated medical devices, most portable oxygen concentrators are quite pricey.
  • Dramatically less-expensive options found online are not capable of producing medical-grade oxygen and are not approved for medical use by the FDA.

If you’re facing the need for oxygen therapy, it might feel like you have to give up the activities you’ve always enjoyed. Images of large rolling tanks and excessive tubing can make any oxygen-dependent diagnosis feel like you’ve lost your freedom. However, thanks to modern technology, you don’t have to.

Compared to the oxygen options of the past, today’s portable oxygen concentrators (POC) are small, sleek, and more capable than ever before. Some claim to be usable 24/7, and recent studies confirm that they are effective enough to be your primary (if not only) source of supplemental oxygen. With many weighing under 5 pounds and batteries lasting for hours, long walks, social events, and even golf days are no longer off the table.

Here at, we understand the benefits of maintaining freedom and mobility, and we believe deeply in maximizing your potential to enjoy all of life’s adventures. We’ve researched the POC models on the market today to offer you reviews of the best options at the most reasonable prices.

Consider This When Buying a Portable Oxygen Concentrator

Flow type

Portable oxygen concentrators are available with pulse flow, continuous flow, or a combination of both. With pulse flow, oxygen release is usually triggered by inhalation. When the user inhales, a dose of oxygen is administered in a volume determined by your prescribed setting. 

Continuous flow produces a steady stream of concentrated oxygen, regardless of whether you’re inhaling, exhaling, or between breaths. Models offering continuous flow typically provide a higher maximum oxygen output, making them preferable for people with prescribed higher flow rates.

Flow rate

The flow rate is what determines how much oxygen is being delivered to you, either per breath (with pulse flow) or per minute (with continuous flow). It’s important to find a model with a flow rate range that can accommodate your needs according to your prescription. 

In pulse flow models, the flow rates available will be on a numbered scale, with most units offering between three and nine flow-rate settings. The models with more setting options allow for more precise dosing, which is beneficial for anyone with more sensitive or specific oxygen needs.

In continuous flow models, the flow rate is set in intervals of 0.5 liters per minute (LPM), with the flow setting between 1 liter per minute to 4 liters per minute or more.

Your ideal flow rate will be determined by your oxygen prescription, but many people benefit from a wider range of flow rates if they often need more during exertion or less during rest.

Size and weight

Although all POCs are by definition designed to be portable, they’re not created equal. Some are heavier or lighter than others, and the dimensions will vary in terms of height, width, and length. How much the size and weight of a unit affects portability will depend on your individual condition. 

For example, some people may find anything over 5 pounds cumbersome, while others can easily lift 10 pounds or more. While these models are designed to be lightweight and portable, factors like continuous flow capability, higher oxygen output, and longer battery life often mean more weight and larger dimensions.

Battery life

Like size and weight, how long a battery lasts on a full charge will directly affect how much mobility you’ll gain from your POC. Shorter battery life means you have less time to spend away from either a charger or other oxygen unit, whereas longer battery life means more time can be spent “unplugged.” 

It’s important to consider your individual needs, as not all people need maximum battery life. For example, if you typically only require oxygen therapy during activity or exertion, models with shorter battery life will have no problem accommodating your needs if your physical activity lasts less than a few hours.

If a model seems ideal on all factors except battery life, purchasing a second battery or a double-size battery is an option that many people choose. Having a spare battery offers extended battery life as well as peace of mind that you won’t be stuck away from home with a dead battery.

FAA approval

Approval from the Federal Aviation Administration is essential if you ever plan to use your POC during air travel. The FAA has strict guidelines for portable oxygen concentrators to be allowed onboard, but luckily most modern devices are FAA-compliant and usually labeled as such directly on the body of the POC.  


Portable oxygen concentrators filter the incoming air before it reaches the other components. Each model requires a specific filter as detailed by the manufacturer. 

Although most filters are designed for easy removal during cleaning or replacement, it’s important to recognize that filter maintenance is essential to keep your POC working properly and delivering filtered oxygen. Luckily, besides battery charging and tubing and cannula replacement, simply replacing or cleaning your POC filter is the only regular maintenance you should have to perform on your machine. 

Sound level

The sound produced by your POC, measured in decibels, will vary greatly between models. A continuous flow unit runs steadily during operation, so it requires a larger motor to produce higher-volume oxygen and is noticeably louder than pulse flow. 

While noise level doesn’t impact the effectiveness of a unit, some older adults find the steady hum of an oxygen concentrator to be embarrassing or distracting in certain settings. Even so, most models are designed to keep the sound level below that of a quiet conversation for the sake of subtlety and portability. 

If you plan to use your POC in quiet places such as a shared office environment, you may want to look for a model with a lower average sound level. 


Some models come standard with a variety of accessories, while others may require additional purchases. Items like a carry bag, rolling cart (for heavier/larger models), cannula and tubing, and charging cable are typically included with the initial purchase of your portable oxygen concentrator.

Accessories available for purchase separately include spare batteries or larger/double size batteries, carrying backpacks, external battery packs, and replacement cannulas.


The manufacturer’s warranty on your device is an important consideration in terms of protecting your investment. Most portable oxygen concentrators offer warranties between three and five years, though they typically break down the warranty into three parts—the portable oxygen concentrator, the battery, and the accessories. 

It’s helpful to be clear about what exactly is covered by the warranty on your POC to avoid any issues or difficulties if you need to make a warranty claim.

Cheap Portable Oxygen Concentrators

Before we dive into our picks for the best cheap portable oxygen concentrators, let’s define what is considered “cheap.” While the most expensive options can cost $4,000 or more, the more affordable models are still a significant investment—$2,000 or more.

When searching for cheap portable oxygen concentrators, you might come across even cheaper options, some even less than $500. However, those machines may not be producing medical-grade oxygen. A concentrator producing medical-grade oxygen will deliver oxygen with an average oxygen concentration of 95% or more. 

Non-medical devices are often sold as “oxygen concentrators” if they deliver anything above the average atmospheric air concentration of oxygen, which is 21% and does not accommodate increased medical oxygen needs.

With that understanding, let’s take a look at our favorite cheap portable oxygen concentrators.

How Oxygen Concentrators Work

Oxygen concentrators work by drawing in the air around you and purifying it to produce concentrated oxygen. The motor draws surrounding air in through a filter, then it passes through a sieve bed where nitrogen is removed. The concentrated oxygen is then compressed and temporarily stored in the machine before being released at a rate according to your settings.

Concentrated oxygen is delivered to you either through your nose with a cannula, or less commonly through your mouth and nose with a mask. The cannula or mask and tubing simply attaches to the outlet port on the machine. 

Once power is turned on, most portable oxygen concentrators have a short “power up” period of a few seconds to a couple minutes. From there, you set your flow rate, attach your mask or cannula, and you’re ready to be mobile and active while receiving your prescribed oxygen therapy.

Who Uses Portable Oxygen Concentrators?

A portable oxygen concentrator is an excellent solution for anyone on oxygen therapy who wants more freedom and mobility than they can get from a stationary concentrator or another oxygen method. Oxygen needs range widely, and many oxygen users are capable of normal activity levels if their oxygen needs are being met. 

The most common conditions that require supplemental oxygen use include:

  • Chronic Obstructive Pulmonary Disorder (COPD)
  • Asthma
  • Pneumonia
  • Pulmonary Fibrosis
  • Sleep Apnea
  • Cystic Fibrosis
  • Lung Cancer

“An increasing number of people suffer from various heart, lung, and other respiratory diseases and require supplemental oxygen therapy at home, when traveling, or while participating in daily activities away from home.”

Snehal Kamble, Marketing Strategist, Straits Research

Although stationary oxygen concentrators are still a widely-used option, “[portable] oxygen concentrators work on a plug-in battery, making them more convenient to use, lightweight, and compact, thus providing easy mobility. These factors contribute to the upsurge in demand for portable oxygen concentrators.”

Do I Need a Prescription to Buy a Portable Oxygen Concentrator?

Yes, you need a prescription to complete the purchase of a medical-grade portable oxygen concentrator in the United States. This restriction is enforced by the Food and Drug Administration, which states: “The FDA has not approved or cleared any oxygen concentrators to be sold or used without a prescription” to avoid misuse and dangerous side-effects like oxygen toxicity.

Though your prescription may be the most important factor in choosing your portable oxygen concentrator, a study from Respiratory Care Journal reiterates that patient choice matters, stating that “the healthcare provider should provide information and help to direct the subject toward the most clinically appropriate oxygen system, while being mindful of the patient’s preferences and lifestyle.”
