What to Know About Portable Oxygen Concentrators

Portable Oxygen Concentrators: Continuous or Intermittent Flow?

Buy only features you need to keep costs and battery use down

Portable oxygen concentrators (POCs) are classified as continuous flow (CF) or intermittent flow (IF). Intermittent flow is sometimes referred to as “pulse flow.”

  • Intermittent flow concentrators are called pulse flow because these concentrators can be set to adjust the rise time, or how quickly or slowly the pulse oxygen is delivered to synchronize with your breathing cycle. Intermittent flow devices only provide oxygen during inhalation, producing nothing during exhalation, thus not wasting oxygen.

  • Continuous flow concentrators deliver oxygen continuously in liters per minute.

When determining which type of portable oxygen concentrator you need, keep in mind the COPD Foundation says for most patients, intermittent flow devices can fully meet the supplemental oxygen needs. Your doctor prescribes a flow amount based on what he or she feels is appropriate for your condition.

Managing the Cost of a Portable Oxygen Concentrator

Save money with rental options and check Medicare or private insurance coverage

Portable oxygen concentrators are costly and for some, buying a POC is financially impossible. Renting your equipment under Medicare Part B as durable medical equipment (DME) can be an excellent money-saving option. Ask your doctor about where you can rent a portable oxygen concentrator. According to, you’ll rent supplies for the first three years at 20 percent of the cost plus any remaining Part B deductible in most cases. After the initial 36 months, your supplier must continue to provide maintenance and service for up to five years at no additional charge as long as you need oxygen therapy. After five years, you can stay with your existing supplier or select a new one and the 36-month rental period starts over.

Portable Oxygen Concentrator Benefits

Let your medical needs, lifestyle and budget determine which POC is best for you

Portable oxygen concentrators are easily moved around the home or are lightweight, wearable devices you can carry with you as you walk, shop, travel or go to appointments. A portable air concentrator designed for home use is a unit either on wheels or a cart that weighs under 20 pounds. Wearable concentrators can weigh less than five pounds, and you can carry them in a small bag or backpack (Buy on Amazon). Most wearable portable oxygen concentrators run on AC or DC power and rechargeable batteries so they can be used at home or on the go. The downside is that the wearable devices are considerably more expensive than their larger, heavier counterparts.

Portable Oxygen Concentrator Company Reviews

When a doctor says that you or a loved one needs long-term oxygen therapy, you might not know where to start. The lack of oxygen often comes from a condition that prevents the lungs from absorbing enough oxygen, including:

  • Asthma
  • Chronic bronchitis
  • Chronic obstructive pulmonary disease (COPD)
  • Cystic fibrosis
  • Heart failure
  • Pneumonia
  • Sleep apnea
  • Other lung diseases

Dealing with one of these diagnoses and subsequent required lifestyle changes is difficult enough without wading through a sea of information from one POC company after another, so we did that work for you. Our in-depth portable oxygen concentrator company analysis included researching 10 of the most common POC companies. Then we narrowed that list based on specific criteria surrounding equipment features, cost, warranties and more. The result is our list of the top six portable oxygen concentrator companies.

Inogen Review

Great Warranty |

In 2001, Inogen CFO Alison Bauerlein’s grandmother was diagnosed with COPD and prescribed oxygen therapy. While the products available at the time allowed her grandmother to breathe, this was not without the hassle of dragging a heavy oxygen tank around. Bauerlein, then a University of California student, wanted to return greater freedom and independence to her grandmother. She and two other students, Brenton Taylor and Byron Myers, developed a prize-winning business plan that became Inogen, a medical technology company dedicated to improving the lives of those who rely on portable oxygen concentrators.

Inogen provides compact, lightweight, portable oxygen concentrators designed for an active lifestyle, with a rare lifetime warranty. You can buy either of these two wearable POCs alone and get a three-year warranty. However, if you purchase an Inogen One G3 or G4 system in one of three Freedom Packages, you will get a lifetime warranty and extra batteries.

Inogen is an ACHC accredited company for oxygen therapy and holds an “A+” rating with the Better Business Bureau. Its portable oxygen concentrators have won awards for design in Medical Design and Excellence categories.

Frequently Asked Questions about Portable Oxygen Concentrators

How does a portable oxygen concentrator work?

The air we inhale usually is 80 percent nitrogen and 20 percent oxygen. A portable oxygen concentrator pulls air in, then concentrates and purifies the oxygen level to deliver 90 to 95 percent pure oxygen and five to 10 percent nitrogen.

What is the difference between stationary and portable oxygen concentrators?

Stationary oxygen concentrators are continuous flow oxygen therapy devices, typically with a large tank. With a stationary oxygen concentrator, you can go about your usual activities at home while using tubing extensions attached to the oxygen tank often as long at 50 feet. Stationary oxygen concentrators are useful while sleeping and the oxygen flow is from one to five flowmeters per minute. Stationary devices are no longer as cumbersome as they once were, with today’s oxygen concentrators being much quieter and no longer requiring the once-customary 50-pound tank. However, SOCs need power from an electrical outlet, restricting use to around the house.

In contrast, the average weight of a portable oxygen concentrator is five pounds and can be as light as around three pounds. POCs can operate on a battery and are worn or carried by the person using the device. These characteristics make a portable oxygen concentrator easy to manage while you are out of the house.

Do I need a prescription to buy or rent a portable oxygen concentrator?

Yes. Any supplemental oxygen is considered a medical treatment. If you need an oxygen concentrator, your doctor may prescribe a specific oxygen flow rate and the length of time you should use the oxygen each day.

Does medical insurance cover a portable oxygen concentrator?

Most insurance companies cover portable oxygen concentrators as durable medical equipment prescribed by a physician. You need to verify coverage with your insurance provider.

Can I take my portable oxygen concentrator on an airplane?

Yes. Since 2009, the Department of Transportation final rule, Nondiscrimination on the Basis of Disability in Air Travel, requires air carriers with passenger service to allow passengers with a disability to use an FAA-approved portable oxygen concentrator on flights. There are currently 23 FAA-approved POCs, including all of the wearable models featured in this guide.

Are there any other considerations I should keep in mind when comparing portable oxygen concentrator companies and products?

Always be sure you understand the company’s return policy and if it includes any restocking fees. Also, check to see how the portable oxygen concentrator company handles service on the machine. Ask if they provide a free loaner POC to use while their technicians service your device. Last, be sure to read the warranty in its entirety so you won’t be caught off guard should you have any issues with your POC.

Concluding Thoughts on Portable Oxygen Concentrators

Bottom Line:
Discuss portable oxygen concentrators with your health care provider before you buy for help with deciding on the features you need so you can remain independent.

Regardless of which portable oxygen concentrator company you decide to go with, select your POC carefully after determining your needs and considering your desired lifestyle. No one portable oxygen concentrator is best for everyone; each has pros and cons, but CAIRE, Inogen and Philips all offer high-quality, dependable products.
