What’s the Difference Between an Oxygen Concentrator and a Portable Oxygen Concentrator?
If you’ve recently been prescribed home oxygen, you may have heard two terms come up: oxygen concentrator and portable oxygen concentrator. They sound similar, and they work on the same principle, but they serve very different purposes in your daily life.
Understanding the difference can help you get the most out of your oxygen therapy, stay comfortable at home, and keep doing the things that matter most to you outside of it.
How an Oxygen Concentrator Works
The air around us is only about 21% oxygen. If your heart or lungs aren’t working at full capacity, that may not be enough to keep your oxygen levels where they need to be. An oxygen concentrator draws in room air, filters out the nitrogen, and delivers air that is up to 95% pure oxygen through a small nasal cannula (the soft tube that rests gently under your nose).
Unlike oxygen tanks, concentrators don’t run out. They produce oxygen continuously from the air already in the room, as long as they have a power source. There are two main types, each built for a different part of your day.
The Home Oxygen Concentrator: Steady, Reliable Support at Home
A home oxygen concentrator is designed to stay in one place (typically your bedroom or living room) and deliver a consistent, uninterrupted supply of oxygen around the clock.
With a long length of tubing, often up to 50-100 feet, you can move freely through your home, to the kitchen, the backyard, or the living room, without disconnecting from the machine. It works quietly in the background so you can rest, sleep, and go about your day without giving it much thought.
What sets it apart:
- Plugs into a standard wall outlet, no batteries or charging needed
- Delivers a continuous flow of oxygen, even while you exhale or while you are sleeping (ideal for overnight use and for those with higher oxygen requirements)
- Larger and heavier than a portable unit, typically 5 to 10 kilograms, but designed to stay put and roll between rooms when needed
- Capable of higher flow rates, which matters for patients with greater medical needs
- Designed to be on all the time!
The Portable Oxygen Concentrator: The Freedom to Keep Living Your Life
A portable oxygen concentrator is a compact, battery-powered version designed to go wherever you go — to medical appointments, family gatherings, the grocery store, a walk around the neighbourhood, or even on an airplane.
Needing supplemental oxygen should never mean staying home. A portable concentrator makes sure it doesn’t have to.
What sets it apart:
- Lightweight and easy to carry, typically 1 to 3.5 kilograms and fits in a shoulder bag or small carry case
- Runs on a rechargeable battery, with many models offering extended battery life; most also include adapters for charging at home, in the car, or from any standard outlet
- Delivers oxygen using pulse dose technology — the device senses when you breathe in and delivers oxygen in that moment, making it efficient enough to run on a battery; some models also offer a continuous flow setting
- Many models are approved for use on commercial flights, so visiting family across the country is still very much on the table
- Oxygen = Battery life! Just bring your charger!
Do You Need Both?
For most people on home oxygen therapy, the answer is yes, and this combination is what we most often recommend. Your home concentrator handles overnight use and time spent at home, delivering steady oxygen without any battery management. Your portable concentrator travels with you whenever you leave the house. Some people with lower oxygen needs do well with a portable unit alone. Others with higher flow requirements rely primarily on their home unit. The right combination depends on your prescription, your activity level, and your lifestyle — something our Registered Respiratory Therapists take the time to work through carefully with you and your family. The good news is the Alberta Government funds both!
