From tanks to true freedom
If you are tired of hauling heavy tanks, scheduling refills, and watching the gauge, here is the simple difference a portable oxygen concentrator (POC) makes.
Oxygen tanks
- × Heavy and bulky to lift and carry
- × Run out, so you ration your time out
- × Refills and deliveries to schedule
- × Tethered to the tank wherever you go
Portable oxygen concentrators
- ✓ About 3 to 6 lb, easy to carry
- ✓ Pull oxygen from the air, never run out
- ✓ Rechargeable batteries, just plug in
- ✓ FAA-accepted, take it on a plane
Pulse dose means the unit delivers a puff of oxygen each time you breathe in. It is lighter and the battery lasts longer.
Continuous flow means a steady stream of oxygen at all times, measured in LPM (liters per minute). Some people need this, especially at night. Your prescription tells you which one is right for you.

The research: decades of evidence support long-term supplemental oxygen therapy. Landmark trials (the NOTT trial, 1980 and the MRC trial, 1981) found that long-term oxygen improved survival in people with chronic low blood oxygen. These studies are about oxygen therapy in general, not any specific device. Always follow your physician's prescription.

What to consider before buying
- Flow type vs prescription. Pulse dose suits many people; some need continuous flow, especially at night. Your prescription decides.
- Battery life vs flow setting. Battery numbers are measured at the lowest setting. Higher settings and continuous flow use power faster.
- Weight and portability. A pound or two matters when you carry it all day. Lighter is easier, as long as it meets your prescription.
- Noise. Quieter units are easier to live with at night and in quiet rooms. Where a maker does not publish a figure, ask us what to expect.
- Warranty and service. Check the unit warranty and the sieve bed warranty, and make sure real service and support stand behind it.
Frequently asked questions
Do I need a prescription?
Yes. Portable oxygen concentrators are FDA-cleared medical devices and a prescription is required for every unit. Do not worry if you do not have the paperwork in hand, our specialists help you complete your prescription as part of the process.
Will Medicare or insurance pay for it?
Medicare and most insurers generally do not cover the purchase of a portable oxygen concentrator. The good news is that financing is available, so you can spread the cost into low monthly payments. Ask a specialist about your options.
Can I use it while sleeping?
It depends on your prescription. Some people are prescribed continuous flow for sleep, in which case a unit like the Oxlife Liberty 2 may be the better fit. Always follow your physician's prescription and ask a specialist which delivery type suits you.
Can I fly with it?
Every unit on this page meets FAA acceptance criteria for use on commercial flights. Airlines have their own notice and battery rules, so check with your airline before you travel, and we can walk you through what you need.
What is the difference between pulse and continuous flow?
Pulse dose delivers a puff of oxygen each time you breathe in, which keeps the unit lighter and the battery longer. Continuous flow delivers a steady stream measured in LPM. Your prescription tells you which one you need.
How long do these units last?
With proper care, a quality concentrator lasts for years. Each unit here comes with a manufacturer warranty (commonly 3 years on the unit), and some offer a lifetime warranty option. Sieve bed and battery warranties may be shorter, so ask a specialist for the details on your chosen model.
