Top 4 Portable Travel Oxygen Devices

Prescribed worldwide, supplemental oxygen therapy is a standard treatment approach for chronic lung diseases and conditions, such as chronic obstructive pulmonary disease (COPD), emphysema, pulmonary fibrosis (PF), asthma, and chronic bronchitis. 

While many people are familiar with the oxygen tanks often used in supplemental oxygen therapy, and even the portable tanks that have wheeled support carts for mobility, not as many know about the multiple benefits of the newly designed portable oxygen concentrators (POCs) available in today’s healthcare marketplace. POCs source oxygen from ambient air, filter and compress it, and deliver it to the patient through a nasal cannula attachment. 

Utilizing state-of-the-art technology, portable oxygen concentrators deliver efficacious therapy comparable to larger, less portable oxygen delivery systems, but they don’t require any tanks. They’re also significantly smaller than home oxygen concentrators and run on rechargeable batteries for hours of reliable therapy.

With their exceptionally lightweight, low profile design, today’s portable oxygen concentrators provide a discreet, effective, and dependable solution for excursions outside the home, including FAA-approved POC air travel. Providing multiple choices, such as continuous or pulse flow, display options, alarm functions, battery time/added batteries and other power preferences, everyone who requires supplemental oxygen therapy is sure to find exactly the right POC for their unique requirements.

What Features Should I Look For?

Determining the best portable oxygen concentrator for your particular needs is an important decision, and you should always consult with your doctor about what specific features you require. Along with that professional help, we’ve compiled some important expert research to help guide your decision so that you can make the best possible choice for yourself or a loved one.

  • Pulse Dose or Continuous Flow - Figuring out how you use your oxygen, and when, will help determine whether you require continuous flow or pulse dose mechanisms of delivery. Continuous flow delivers oxygen at a continuous, regular rate, while pulse dose or pulse flow delivers the oxygen at a predetermined rate with a specific setting, based on the individual’s own rate of breathing. Pulse dose only expels oxygen to the user as the user inhales, and is often sufficient for most patients requiring supplemental oxygen.
  • Size and Weight - Portable oxygen concentrators come in both larger, wheeled models, and smaller sizes that are around 5 pounds or less in weight. Because the smaller units in our review work just as well as their larger counterparts, we suggest you select a smaller, lightweight POC as they are so much more comfortable and easy to carry and transport. If you use air travel, it’s important to ensure you choose an FAA-approved portable oxygen concentrator, which most small units are.
  • Durability - As a considerable investment, you’ll want to make sure the POC you select is built to last, and can withstand some bumping and knocks, especially during travel and outdoor excursions. All of the POCs highlighted in our review are highly durable, with specialized design features to protect against damage and quality parts that can withstand hard and repetitive usage. 
  • Filters - Most portable oxygen concentrators offer some kind of filtration system to keep the system clean. Simple particle filters remove dander and dust from the oxygen supply, while others include HEPA or antibacterial filters for users more prone to respiratory infections, or those who have weakened immunity issues. 
  • Display - User-friendly interfaces and operational controls are a definite plus when using POCs. Screens should be easy to read, with large enough buttons on the control to avoid pressing the wrong ones, and the device should include alarms to alert you to issues like a low battery, oxygen flow problems, and other operational malfunctions. 
  • Noise - While most of the smaller portable oxygen concentrators are quiet, there are some models that are louder and give off a noticeable background noise when in operation. Decibel levels around 40 dbA are at the same level as a whisper, and preferable for use in sound or noise-sensitive environments. 
  • Battery Life - Battery life for most of the smaller POCs typically ranges between 2-4 hours, depending on what pulse or continuous flow rate they’re set at. Extra batteries, battery chargers, and AC or DC power supplies will help tremendously in ensuring you always have supplemental oxygen available when you’re on the go. POCs that enable charging as they still provide oxygen are a great choice, too.
  • Accessories - While most of the smaller portable oxygen concentrators come standard with the unit, a battery, an AC power supply, a DC power supply, and a carrying case, there is usually a range of add-on options to further customize the POC’s use to each individual’s unique needs. Replacement parts like sieve beds, filters, and panel vent covers will help extend the life of the POC, and extra batteries or battery chargers provide alternative power options.


How do portable oxygen concentrators work?

Like regular, larger oxygen concentrators for home use that are plugged into the wall, portable oxygen concentrators are powered by a rechargeable battery or an electrical source, and take oxygen from the surrounding air, filtering it through sieve beds to remove the nitrogen. Compressed within the device, the oxygen is then delivered to the patient via a nasal cannula that’s attached to the portable oxygen concentrator. 

Can you use a portable oxygen concentrator at night?

While it’s usually okay in most circumstances to sleep with a portable oxygen concentrator, this is an issue that should always be discussed with your doctor. There may be certain contraindications for use with some patients, and others may actually require a CPAP machine to more effectively treat issues like sleep apnea.

Are portable oxygen concentrators allowed on airplanes?

Most airlines and the TSA allow small portable oxygen concentrators aboard planes in both carry-on and checked luggage. If you’re flying internationally, be sure to check the regulations for each country. Contact your airline to ensure your POC complies with regulations, and that you follow any special procedures or instructions from them or the Transportation Security Administration (TSA). 

Will Medicare pay for a portable oxygen concentrator?

Although Medicare will pay for the cost of a portable oxygen concentrator to a homecare equipment provider you may use, it’s a complicated process and is dependent on several factors. It is often quite difficult to actually find a local company that will supply a small POC for you, as they tend to offer systems that use tanks, or larger concentrators for stationary home use.

Are portable oxygen concentrators covered by insurance?

Although they greatly improve quality of life for people with a range of respiratory disorders and conditions and are much smaller and easier to travel with than heavy oxygen tanks, portable oxygen concentrators are considered luxury items, and it may be difficult to get your insurance company to cover the cost. To maximize your chances, be sure your paperwork is correct and organized, including the order and relevant patient information from your doctor. Encompassing all the ways that a POC would improve the quality of your life in all its aspects over the use of the standard oxygen tanks, giving as many details as possible, will generally be your best chance of your insurance covering the cost. 

Does the VA supply portable oxygen concentrators?

Even though the Veterans Administration will not typically supply portable oxygen concentrators for long-term use, they do often issue them to Vets for temporary situations, such as plane trips and other travel, supplying them where Vets will be staying. 


Portable oxygen concentrators are life-saving medical devices that help people with compromised respiratory conditions to breathe more easily, providing supplemental oxygen derived from ambient air. Because they don’t require the use of large and heavy oxygen tanks, they are much easier to travel with and are now available in super small designs that work just as effectively as their larger counterparts. 

POCs improve quality of life for their users, enabling people to remain active and engaged in business, social, and recreational pursuits, enhancing freedom and independence to move about their world with ease. We researched the best portable oxygen concentrators available in today’s rapidly changing, high tech, and innovative marketplace for our review, and described the features, benefits, and customer feedback for our top choices to help you select the best POC for yourself or a loved one.
