Using an oxygen concentrator can increase quality of life and enhance health for people with certain medical conditions like COPD, emphysema, or heart failure. Air contains only around 21% oxygen, but oxygen concentrators filter out contaminants and other elements, like nitrogen, and deliver 90% oxygen or higher to the user. A stationary or home oxygen concentrator can make it easier for your body to get the oxygen it needs to function properly without having to deal with oxygen tanks that must be refilled or replaced. Today, there are more options than ever when it comes to home O2 concentrators, but how do you know which one is right for you? Whether you’re on a budget, have high oxygen needs, or are simply looking for a machine that’s easy to move from room to room, here are our top five best oxygen concentrators for home use.
The best overall oxygen concentrator for home use: OxyGo OxyHome
| Pros | Cons |
| Modern design with a white exterior. | Weighs 41.8 pounds. |
| Sound level of less than 45 dBA. | Setting adjustment isn’t intuitive. |
| Features side and top handles and rotating wheels for easy maneuvering. | No quick-start guide or video instructions. |
| Measures 13.4″ × 11.8″ × 25.6″. | |
| Three-year manufacturer warranty. | |
| Flow rate of up to 5 liters of oxygen per minute. | |
| User-accessible circuit breaker. | |
| Costs under $1,000. | |

The brand
Unlike other well-known brands that have been around for decades, OxyGo is a relative newcomer in the oxygen concentrator space. They released their first portable O2 concentrator in 2014 and only just released the OxyHome stationary concentrator in 2023, but their newcomer status comes with a fresh perspective on design and functionality.
Appearance
The OxyHome has a sleek, modern look, unlike some other home oxygen concentrators on the market. It features a white exterior with black accents, allowing it to fit seamlessly into any interior space. Although it is heavier than some other home oxygen concentrators at 41 pounds, it has a relatively small footprint at 13.4″ × 11.8″ × 25.6″. It also has side handles, a top handle, and rotating wheels that make it easy to move from room to room.
Oxygen delivery
OxyGo’s OxyHome supports an oxygen flow of up to 5 liters per minute (LPM) on continuous flow with an average oxygen concentration of 93%, making it a good choice for those with low or moderate oxygen needs. You can choose your setting by using a knob on the front of the device to move a ball in the flow meter tube to your prescribed oxygen rate. It can be a bit trickier to set than simply pushing a button, as you do with other oxygen concentrators, but it does allow for half settings, giving you more nuanced control over your oxygen delivery options.
Unique features
The OxyGo OxyHome has a few unique features that aren’t common among home oxygen concentrators. Like most O2 concentrators, the OxyHome has a circuit breaker that automatically shuts off the machine to prevent overheating, electrical damage, and malfunctions. What makes the OxyHome unique is that the circuit breaker is user-accessible, which means you can reset the machine and turn it on again without having to contact the manufacturer or schedule a repair.
It also features an auxiliary port that allows you to fill portable oxygen canisters if you have a home fill unit, like the Invacare HomeFill Oxygen System. That’s handy if you use portable oxygen canisters when you’re outside of the home.
Price
One of the OxyHome’s biggest selling points is its price, which is one of the reasons it topped our list as the best oxygen concentrator for home use. The OxyHome’s starting price is just $695.00, which is a lot lower than some other units on the market. Even at such a low price, it comes with a three-year warranty.

The best affordable oxygen concentrator for home use: HACENOR HOC-02
| Pros | Cons |
| Pricing starts at just $199. | No wheels or cart. |
| Delivers up to 9 LPM. | Comes with only a one-year warranty. |
| Weighs less than 13 pounds. | Oxygen purity decreases at higher settings. |
| Uses only 150 watts of power. | |
| Sound level of less than 45 dBA. | |
| Can be operated with a remote control. | |
| Anion function purifies the air. | |
| Atomization port for nebulizers. | |
| No prescription needed. |
The brand
Headquartered in China with devices shipped from California, HACENOR offers a variety of portable and home oxygen concentrators, including the HOC-02. Although very responsive, customer service is based in China, so there is the potential for a language barrier.
Also, HACENOR offers fewer informational resources than other brands. The manual is minimal, and there are no startup guides or videos. Fortunately, though, operating the machine is very intuitive, with those who reviewed the O2 concentrator saying it is easy to use.
Appearance
The HACENOR HOC-02 is smaller than many other home oxygen concentrators. It weighs less than 13 pounds and measures 8.27″ × 8.27″ × 11.02″. It features a smooth white exterior with a black top and bottom, giving it a modern appearance that doesn’t look like a medical device. With its small size and top handle, it’s easy to set the oxygen concentrator on a table or the floor. However, because it doesn’t come with wheels or a cart, it can be difficult to move for those who struggle with grip strength.
Oxygen delivery
This home oxygen concentrator can deliver up to 9 liters of oxygen per minute on a continuous-flow setting. However, it is important to be aware that oxygen purity levels decrease as the flow rate increases.
For example, the oxygen purity is 93% at a flow rate of 1 liter per minute. At 4 liters per minute, it decreases to 65%, with the HOC-02 delivering an oxygen purity level of only 30% at 9 liters per minute. That’s still higher than the average oxygen concentration in the air but much lower than other O2 concentrators that can continue offering a purity level of 90% or more, even at higher settings.
Unique features
The HACENOR HOC-02 offers some unique features that you won’t find with other oxygen concentrators. It has an anion function, which electrically charges air molecules, separating dust, allergens, and bacteria, potentially making the air you breathe through the concentrator cleaner.
It also has a nebulization nozzle and comes with an atomization cup. This eliminates the need for a separate device when taking nebulized medications.
One big selling point of this particular home O2 concentrator is that it’s the only one on our list that doesn’t require a doctor’s prescription, which can make the purchasing process simpler. However, you should never use an oxygen concentrator without a doctor’s prescription, because using supplemental oxygen when you don’t need it can be very dangerous or even fatal. In addition, it’s important to learn from a doctor how much oxygen you need so you can choose the right setting on your machine.
Price
This machine made our list as the best oxygen concentrator for home use when it comes to price because it starts at just $199. Even those on a strict budget can afford the HACENOR HOC-02. It comes with only a one-year warranty, but at such a low price point, it’s inexpensive to replace if something goes wrong after the warranty period ends.

The best home oxygen concentrator for users with high oxygen needs: CAIRE NewLife Intensity
| Pros | Cons |
| Delivers up to 10 LPM. | Expensive starting price. |
| Can support long cannula tubes. | Weighs 58 pounds. |
| Oxygen purity level of 90%, even at 10 LPM. | Uses 590 watts of power. |
| Can operate in extreme environments. | Minimum oxygen flow of 2 LPM. |
| Dual-flow option allows for two simultaneous users. | |
| Low dBA for a powerful oxygen concentrator | |
| Built-in wheels. | |
| Three-year manufacturer warranty. |
The brand
CAIRE is a trusted medical device company that has been manufacturing oxygen supply equipment for decades. Physicians and oxygen users often choose CAIRE for their reliable equipment, customer support, and robust three-year warranty. Their line of oxygen concentrators includes portable and home-based machines, including the NewLife Intensity, which is a powerful machine specially designed for care settings and those with high oxygen needs.
Appearance
The design of the NewLife Intensity prioritizes functionality over style. Its boxy shape, gray exterior, and prominent warning labels clearly identify it as medical equipment.
In order to generate the power to support high oxygen purity levels at high flow settings, the home oxygen concentrator has to be quite large. It weighs 58 pounds and measures 27.5″ × 16.5″ × 14.5″, making it the heaviest and largest machine on our list. It does have wheels and handles, which allow you to move the machine around without having to pick it up.
Oxygen delivery
The NewLife Intensity delivers a continuous flow of up to 10 liters of oxygen per minute. It is an ideal home oxygen concentrator for those with high oxygen needs, but it’s not a good fit for those with lower oxygen needs. It has a minimum flow setting of 2 liters per minute, so those with oxygen prescriptions under 2 LPM will not be able to use this machine.
The CAIRE NewLife Intensity is an impressive O2 concentrator not only because of its high flow rate but also because it can maintain high oxygen purity. It averages 92% pure oxygen at settings between 2 and 9 LPM, with an average oxygen concentration of 90% at 10 LPM. In addition, it can maintain high flow rates and oxygen purity in extreme conditions: It can function at temperatures between 41 and 104 degrees Fahrenheit and up to 95% humidity.
Unique features
This home oxygen concentrator is powerful enough to have a 20 psi outlet pressure, which allows it to support up to 200 feet of cannula tubing. With this benefit, you can move around your home freely without having to lug the machine behind you.
That level of pressure also means the oxygen concentrator can support more than one user. Dual-flow units allow two users to use the machine at the same time, which can be handy if you and your partner both require oxygen. You can also purchase a SureFlow device that can split a single source of oxygen into five separate sources, making it a good choice for senior living facilities and care homes.
Price
There are a few different versions of the NewLife Intensity, so while shopping, make sure you’re getting the device you want.
There is both an 8 LPM and a 10 LPM version, although the 10 LPM version is the most common. It starts at $1,750, which is more expensive than some of the other machines on our list, but it’s a reasonable price point considering its power. The 8 LPM version is more affordable with a starting price of $1,025.00. It supports lower settings, making it a better choice for those with low oxygen needs.
As mentioned above, there is a version that supports two users, but these units cost more. For example, the dual-flow 10 LPM concentrator costs $2,000 at My Medical Outlet.

The most energy-efficient oxygen concentrator for home use: Inogen At Home
| Pros | Cons |
| Uses just 100 watts of power on flow setting 2. | No wheels. |
| Sound level of 40 dBA on flow setting 2. | Expensive starting price. |
| Weighs only 18 pounds. | Alarms can be confusing. |
| Measures 7″ × 13″ × 16.5″. | |
| Three-year warranty with optional lifetime warranty. | |
| Simple control settings go up to 5 LPM. |
The brand
Founded in 2001, Inogen is a well-known name in the oxygen concentrator space. Their dedication to excellence, integrity, and service is well-known and respected. Products are designed and assembled in the United States, and all machines come with a three-year warranty with the option to upgrade to a lifetime warranty for an additional fee.
Appearance
Despite being a stationary concentrator, the Inogen At Home is not as bulky as other machines on the market. It measures just 7″ × 13″ × 16.5″ and weighs only 18 pounds. While it has a handle for carrying and maneuvering, it does not have wheels, and there are no carts or bags designed specifically for the At Home machine. That can make it difficult for those with reduced strength to move the device around.
It has a molded white exterior with a light blue handle and matching bottom, so it looks less like a medical device and more like a modern piece of technology. Without a screen, controls are simple and intuitive, but alarms can be difficult to understand, requiring you to look them up in the manual.
Oxygen delivery
The Inogen At Home stationary oxygen concentrator can deliver up to 5 liters per minute. As one of the quietest machines on the market, it has a noise level of only 40 dBA on flow setting 2.
Settings are easy to understand, with setting 1 delivering 1 LPM, setting 2 delivering 2 LPM, and so on. Although the settings are intuitive, there are no half settings, which may cause issues for users requiring more precise oxygen levels.
This home oxygen concentrator maintains a high oxygen purity level ranging from 87% to 96% at all settings.
Unique features
One of the biggest selling features of the Inogen At Home is that it uses very little power. On setting 2, it uses only 100 watts of power, which is the same as using a standard 100-watt light bulb. Even at the highest setting, it only uses 275 watts, which is lower than many other in-home oxygen concentrators. This is the perfect machine for those with low to moderate oxygen needs who want to keep their utility bills low.
Price
The Inogen At Home stationary oxygen concentrator is relatively expensive, with a starting price of $1,703. If you want to save some money, consider buying a used machine for $899. Just make sure you choose a certified refurbished machine, which comes with a one-year warranty.

The best transportable home oxygen concentrator: CAIRE Eclipse 5
| Pros | Cons |
| Option to choose between continuous-flow and pulse-dose settings. | Flow settings and alarms aren’t intuitive. |
| Comes with a removable cart with wheels and an extendable handle. | Most expensive oxygen concentrator on our list. |
| Runs on both electricity and battery power. | A licensed equipment provider must replace internal filters annually. |
| Can be paired with the myCAIRE app. | |

The brand
The Eclipse 5 is the second CAIRE device on our list of the best oxygen concentrators for home use, which is a testament to their reputation for being a high-quality, trustworthy brand. Headquartered in Ball Ground, Georgia, with facilities all over the world, CAIRE has been a leader in oxygen concentrators for over 50 years.
Appearance
The CAIRE Eclipse 5 features a rounded gray case, giving it a sleek look. It’s relatively small at just 19.3″ × 12.3″ × 7.1″, and it only weighs 18.4 pounds. A top handle makes it relatively easy to lift, and it also comes with a removable cart with wheels and an extendable handle so you can pull it behind you when walking, running errands, or moving from room to room.
Oxygen delivery
Unlike most home oxygen concentrators that only offer continuous-flow settings, the Eclipse 5 offers both continuous-flow and pulse-dose settings.
However, it isn’t as powerful as some of the other machines on our list. Continuous-flow settings go up to only 3 liters per minute. Pulse-dose settings top out at just 192 mL per bolus, or burst, when you breathe in. It isn’t a good choice for those with high oxygen needs, but it could be the right O2 concentrator for those with low or moderate oxygen needs who want some flexibility in how their oxygen is delivered.
Unique features
The Eclipse 5 is unique because it’s a transportable home oxygen concentrator. That means you can plug it into the wall and use it as a stationary unit, but it also has a battery and a cart with wheels so you can use it on the go.
Another unique feature of this O2 concentrator is that it is one of the few home oxygen concentrators that can be paired with an app. The myCAIRE app allows you to:
- Easily access the user manual.
- View device notifications.
- Monitor the flow settings you’re using.
- Give access to your care team and family members.
- Request filter replacement services from your equipment provider.
- Troubleshoot problems with your equipment provider.
Price
The Eclipse 5 is the most expensive home oxygen concentrator on our list. Pricing starts at $2,840, but most equipment providers price this O2 concentrator at $3,200. Certified pre-owned and refurbished machines cost around $1,500.
Because the Eclipse 5 is so popular, you can find outlets that rent the machine, and some even offer rent-to-own programs. The nice thing about renting an oxygen concentrator is that you can try it out before buying it.
