What Is a Portable Oxygen Concentrator?
A portable oxygen concentrator (POC) is a compact, portable version of a regular-sized oxygen concentrator. These devices provide oxygen therapy to people with health conditions that cause low oxygen levels in the blood such as COPD, asthma, and lung cancer.
Oxygen concentrators contain compressors, filters, and tubing. A nasal cannula or oxygen mask connects to the device and delivers oxygen to the person who needs it. Note: Oxygen masks should only be used with higher liter flows, such as 5 liters per minute or over as rebreathing exhaled carbon dioxide could occur. Concentrators are tankless, so there’s no risk of running out of oxygen. However, as with any piece of technology, these machines can potentially malfunction.
Portable units typically have a rechargeable battery, which allows for use on the go, such as while traveling. Most can be charged via an AC or DC outlet and can operate on direct power while charging the battery to eliminate any potential downtime.
How Oxygen Concentrators Work
To deliver oxygen to you, the devices draw air from the room you’re in and pass it through filters to purify the air. The compressor absorbs nitrogen, leaving behind concentrated oxygen. The nitrogen is then released back into the environment, and the person receives oxygen through a pulse (also called intermittent) flow or continuous flow (depending on the machine) mechanism via a nasal cannula.
Types of Portable Oxygen Concentrators
Portable oxygen concentrators deliver oxygen by either pulse flow or continuous flow. Both methods deliver oxygen to the lungs through inhalation, but each is appropriate for different conditions or situations.
Pulse flow: A pulse device delivers oxygen in bursts, or boluses, when you inhale. Pulse flow oxygen delivery requires a smaller motor, less battery power, and a smaller internal reservoir, allowing pulse flow devices to be incredibly small and efficient. Since pulse flow is generally triggered by inhalation, the user must have strong enough inhalation to trigger delivery. Also, because pulse flow units have generally low maximum oxygen outputs, they aren’t suitable for people who require more than one to two liters of oxygen per minute.
Continuous flow: Most portable units offer only pulse flow delivery, but some are also capable of continuous flow oxygen delivery. Continuous flow devices churn out oxygen at a steady rate regardless of the user’s breathing pattern. Because they need to pump out oxygen continuously, they tend to have larger compressors, which makes them weigh more. Continuous flow delivery is usually indicated for people with weaker respiration, higher oxygen needs, or during sleep when breathing may be unsteady or less efficient.

Tip: We do our best to thoroughly analyze product reviews and understand what people are saying about these products online. What we’ve found in our research is that, very often, reviews written about portable oxygen concentrators and other similar medical devices are incorrectly targeted. For example, POC manufacturers sell their products through multiple retailers across the country. When people have an issue or problem with the retailer they purchased from, they may post a review of the manufacturer on Trustpilot or file a complaint with the Better Business Bureau. This can be confusing and often misrepresents the product itself, so be sure to read reviews critically to be clear about what is really being discussed.

How Much Do Portable Oxygen Concentrators Cost?
Because portable oxygen concentrators are prescription medical devices, not all retailers will make pricing information readily available. Additionally, insurance and other factors may impact the overall cost.
When looking at the cost of each model, the cost can vary with the addition or removal of certain options. For example, many models offer the option to purchase your device with a double size battery as opposed to a single battery, which typically adds a few hundred dollars to the total. Other options may include accessories or upgraded warranty or service plans.
You can also buy or rent these devices used for a fraction of the cost. Used devices are usually refurbished and in excellent working condition, but price and warranty coverage for refurbished models will vary from one retailer to the next. New unit pricing also varies by retailer, but you can expect to pay at least $2,000 for most new portable oxygen concentrators.
Things to Consider When Shopping for a Portable Oxygen Concentrator
Once you receive a prescription from a health care professional, you need to consider oxygen output, weight, flow type, noise levels, battery life, and price while shopping for a portable oxygen concentrator. Also, keep in mind that most insurances will not pay for you to have both a portable concentrator and a stationary concentrator at home.
Oxygen Output
How much oxygen a unit puts out will likely be your primary consideration. The purity of that oxygen is an additional consideration. Your needs will vary depending on your condition and prescription. When discussing your oxygen prescription your health care provider will give you a more specific idea of what to look for.
Most units have multiple settings that allow you to adjust output depending on your needs and prescription as written, and the maximum output varies by model. It’s important to remember that, while continuous flow measurement is clearly stated as liters per minute (LPM), pulse flow settings can represent different flow rates from one model to the next. For example, a pulse flow setting of “3” on one model may not represent the same output volume as the same setting on a different model.
Weight
Portable oxygen concentrators are designed to be just that: portable. However, size and weight vary depending on the type of device. Most continuous flow devices, even the portable ones, tend to be heavier, weighing in at around 20 pounds. Pulse flow devices are usually lighter, weighing between 4 and 12 pounds. Some have handy carrying straps.
If you’re in the market for a portable continuous flow unit, it’s worth noting that many feature rolling carts designed for easy transport, like the Philips Respironics SimplyGo. The weight of your portable oxygen concentrator will affect how mobile you can be while carrying it, and a machine that’s too heavy can even cause unnecessary exertion and increase breathing rate and demand for oxygen.
Quick tip: If you plan on traveling with your portable concentrator, make sure that it’s FAA-approved.
Noise Levels
A benefit of portable oxygen concentrators is that they are quieter than their full-size counterparts. Most of them register under 50 decibels, which is quieter than a normal conversation, and a few are even quieter. If you plan to use your portable concentrator to sleep, opt for the quietest unit that still fits your oxygen needs.
Battery Life
Portable oxygen compressors feature rechargeable batteries that allow you to use the units when you’re away from a power source. To choose a model with sufficient battery life, you’ll need to make an honest assessment of your needs and lifestyle.
Models with the longest battery life are great options for people who want to travel, leave home for much of the day, or rely on their portable concentrator as their primary oxygen source at home.
On the other hand, models with shorter battery life are often smaller and lighter as we see with the Inogen One G4 System. These units are a great choice for people who need a compact device for short periods of time and who may frequently return home or elsewhere where charging is easy and accessible.
Units capable of meeting high oxygen needs tend to have less battery life than those with lower oxygen output. Battery life varies depending on use and selected settings, and maximum battery life values reflect use at the lowest settings.
Who Needs a Portable Oxygen Concentrator?
The need for supplemental oxygen will be determined by your physician, and there are a number of conditions that are likely to cause low blood oxygen levels. You may already be using oxygen or have recently gotten a new prescription. Conditions that often require oxygen therapy may include:
- Chronic obstructive pulmonary disease (COPD)
- Severe asthma
- Sleep apnea
- Cystic fibrosis
- Heart failure
- COVID-19
Remember that oxygen concentrators, portable units included, are prescription-only devices. The Food and Drug Administration (FDA) warns against using this medical device unless your doctor has determined that you need it and has given you a prescription. Using oxygen devices without a prescription can be dangerous—incorrect or excessive use of inhaled oxygen can cause symptoms like nausea, irritability, disorientation, coughing, lung irritation, and potentially cessation of breathing.
Individual oxygen needs, including continuous flow versus pulse flow delivery, will be determined by your physician. Your oxygen prescription, combined with your personal preferences and lifestyle, will help you narrow down which devices are appropriate for you. When you find the right device, a portable oxygen concentrator may help you:
- Breathe more easily. Oxygen therapy can help decrease shortness of breath and improve your ability to perform daily activities.
- Have more energy. A portable oxygen concentrator can also reduce fatigue and make it easier to complete daily tasks by increasing your oxygen levels.
- Maintain your usual lifestyle and activities. Many people with supplemental oxygen needs are capable of maintaining a high level of reasonable activity, and portable oxygen concentrators offer the opportunity and freedom to do so.
“Portable oxygen concentrators are most suitable for conditions that result in low blood oxygen levels. They work by supplementing naturally inhaled air to provide enough gaseous nutrition to vital cells and organs, This can be beneficial for older adults who suffer from ailments like Chronic Obstructive Pulmonary Disease (COPD). However, with the rising incidence of Obstructive Sleep Apnea and cardiovascular diseases like heart failure among older adults, POCs can be invaluable for individuals within this age group. The elderly body has a generally weaker, slower-responding immune system. Oxygen from a POC can help support some senior patients’ recovery from severe injuries and invasive operations.”

How to Get a Portable Oxygen Concentrator
The first step towards getting a portable oxygen concentrator is talking to your doctor to make sure a portable unit will work for you. Once your doctor confirms that a portable concentrator can meet your needs, he or she will clarify or confirm your oxygen prescription. From there you can start shopping and pick the right portable oxygen concentrator for you and your lifestyle.
Buying a Portable Oxygen Concentrator
If you choose to purchase your concentrator, you can either begin to research models on your own or consult a retail sales representative to narrow down your options. Once you’ve chosen the model that best suits your needs, you will be required to submit your oxygen prescription. This both confirms that you are a prescribed oxygen user and that the model you’ve chosen can accommodate your oxygen requirements. Once your prescription has been reviewed your insurance or Medicare can be consulted about possible coverage or reimbursement, and your purchase can be finalized.
Renting a Portable Oxygen Concentrator
If you choose to rent instead of purchasing your concentrator, the procedure will be similar and will involve submitting your prescription prior to receiving your device. Programs like Medicare may cover the rental cost of your POC, particularly if your oxygen needs are temporary due to something like illness or necessary extended travel away from your in-home unit.
Portable Oxygen Concentrator Rating Methodology
When selecting the best portable oxygen concentrators for our list, we took into consideration the following criteria:
- Portability: We only included actual portable units that feature rechargeable batteries and are easy to carry around. Portable units are typically carried or sometimes wheeled on carts and are lightweight enough that most users can lift or move them without difficulty.
- Oxygen availability: Everyone’s oxygen needs are different, so we compared each machine’s ability to meet oxygen needs according to pulse flow setting range and maximum continuous flow delivery.
- Battery life: Besides weight, battery life is the next most important factor affecting portability. Longer battery life is ideal to maximize mobility and freedom from being plugged in while receiving oxygen therapy. Battery life varies by setting and maximum values represent battery life when used at the lowest setting.
- Battery recharge time: Recharge time affects the user’s overall freedom from being “plugged in,” although not to the same extent as battery life. For those using only one battery, this factor represents how long they have to wait before they can be mobile and “portable” again.
