Best Portable Oxygen Concentrators

Profile picture of Kathryn Parkman
by Kathryn Parkman ConsumerAffairs Research Team

Patients who require supplemental oxygen often prefer portable oxygen concentrators (POCs) over oxygen tanks for the convenience. Oxygen tanks, which are typically used in the home or a hospital, can weigh more than 150 pounds and must be regularly re-filled with liquid or compressed oxygen.

The reason why a portable oxygen concentrator is lighter and easier to travel with is that it doesn’t require a tank. About the size of a lunchbox, a portable oxygen concentrator is battery-powered and sources oxygen from ambient air in the room, so it never has to be plugged in or refilled.

About portable oxygen concentrators

What is a portable oxygen concentrator?

Portable oxygen concentrators are medical devices that deliver oxygen therapy to people who cannot source enough oxygen on their own. Portable oxygen concentrators weigh less and are easier to travel with than home oxygen devices.

How do portable oxygen concentrators work?

Unlike conventional oxygen tanks, portable oxygen concentrators source oxygen from ambient air and filter it through bed sieves to remove the nitrogen. The oxygen is then compressed in the machine before it is delivered to the user when it flows through a nasal cannula.

How much does it cost to rent a portable oxygen concentrator?

The average cost of renting a portable oxygen concentrator is $840 per year, per unit. For qualifying patients, Medicare and other insurances may be able to reduce out-of-pocket fees for portable oxygen concentrator rentals.

Are portable oxygen concentrators covered by insurance?

In the United States, insurance companies are only required to supply medical equipment that maintains a patient’s basic oxygen needs. Typically, a patient’s basic oxygen needs can be met with less costly devices, and so it is unlikely the purchase of a portable oxygen concentrator will be covered by insurance.

Are portable oxygen concentrators covered by Medicare?

It is unlikely that Medicare will provide you with a portable oxygen concentrator. They are only required to meet patients’ most basic oxygen needs, which can usually be met with less costly oxygen tanks.

Medicare coverage of portable oxygen concentrators dropped by 50 percent in 2013. Since then, respiratory equipment suppliers provide less costly oxygen tanks over high-dollar portable oxygen concentrators for Medicare patients. In the event you have to travel by plane, Medicare will not pay for a portable oxygen concentrator, though you may be able to rent one from your oxygen supplier.

Types of portable oxygen concentrators

Disclaimer: Always consult a medical professional to determine the type of concentrator most suited to your lifestyle.

Continuous flow portable oxygen concentrators

The most common type of oxygen concentrator delivers a steady stream of oxygen to users (home oxygen concentrators are always continuous flow units).

  • Oxygen flow: delivers up to 3,000 mL of oxygen per minute
  • Weight: 10–20 pounds
  • Best for: Patients who require 2–5 liters of oxygen per minute. Continuous flow machines are typically heavier than pulse flow units and are recommended for use when sitting still or sleeping.

Pulse dose portable oxygen concentrators

With pulse dose units, oxygen is delivered to the user intermittently, in regular spurts based on the patient's breathing rate.

  • Oxygen flow: delivers between 450 mL to 1,250 mL of oxygen per minute
  • Weight: 2–10 pounds
  • Best for: Patients who require less than 2 liters per minute of oxygen. Because pulse dose units are lighter than continuous flow portable oxygen concentrators, they are recommended for more active users.

Common questions about portable oxygen concentrators

Who needs oxygen therapy?

Those suffering from respiratory diseases like chronic bronchitis, emphysema, pulmonary fibrosis or certain heart problems and neuromuscular conditions are prescribed supplemental oxygen therapy to alleviate symptoms like headaches, dizziness, shortness of breath, visual disturbances, high blood pressure and rapid heartbeat.

 Are portable oxygen concentrators dangerous?

Oxygen therapy creates a fire risk, as oxygen is highly flammable. You should never smoke near oxygen or use oxygen near an open flame. Oxygen concentrators shouldn’t be used in small, unventilated rooms.

Can you travel with a portable oxygen concentrator?

Unlike oxygen tanks or liquid oxygen, oxygen concentrators are approved by the FFA for air travel. Individual airlines may have their own rules or regulations, like requiring a physician’s statement of your medical need for oxygen. Be sure to bring enough batteries for the duration of your flight.
