If you have a chronic respiratory condition—such as asthma, chronic obstructive pulmonary disease (COPD), lung disease, or obstructive sleep apnea (OSA)—you may not receive enough oxygen. According to the U.S. Food & Drug Administration (FDA), healthy blood oxygen saturation levels fall at about 95% or higher. [1]U.S. Food and Drug Administration. Pulse Oximeter Accuracy and Limitations: FDA Safety Communication. Nov. 7, 2022. Found on the internet at https://www.fda.gov/medical-devices/safety-communications/pulse-oximeter-accuracy-and-limitations-fda-safety-communication Respiratory conditions can make it difficult to meet those levels.

Supplemental oxygen devices, like home oxygen concentrators (HOCs) or portable oxygen concentrators (POCs), can help raise your blood oxygen levels. The best HOC for you depends on your oxygen prescription and individual preferences.

To help guide you in your search for the best HOC, our Reviews Team analyzed several, ranking them based on price, weight, sound level, and mobility.

Best home oxygen concentrators in 2024

CAIRE Companion 5

Best Value
Price: $595
Maximum oxygen output: 5 liters per minute
Power consumption: 250–350 watts per hour
Dimensions: 12.5 inches wide x 13.5 inches deep x 21.5 inches high
Weight: 36 pounds
Why we chose

The CAIRE Companion 5 is the most budget-friendly HOC model on this list. On its highest setting, the machine only consumes 350 watts of power, which saves energy and makes it our Reviews Team’s “Best Value” pick.

Pros & cons
Pros Precise oxygen dosing Power-saving options Has wheels for portability Cons Heavier than similar models No handle for moving
Additional details

The CAIRE Companion 5 pairs key features found in similar models with an affordable $595 price tag. The Companion 5 delivers oxygen in half-liter increments, allowing for precise dosing for those needing only a few hours of oxygen therapy during the day or overnight.

One of the standout features of the CAIRE Companion 5 is the concentrator’s power-saving autoFLOW technology. AutoFLOW technology reduces the machine’s power consumption significantly, from 350 watts to around 250 watts. But, the feature only works when the HOC is operating at or under 2 liters per minute.

The CAIRE Companion 5 has an easy-to-read screen with a green light when it’s turned on and warning codes to indicate if the machine is malfunctioning. The model is 21.5 inches high and 12.5 inches wide and should easily fit near your bed or a couch. The model’s 36-pound weight makes lifting slightly challenging, though it is equipped with wheels for mobility when not in use. At 50 decibels, this HOC is about the same noise level as moderate rainfall. [2] International Noise Awareness Day. Common Noise Levels – How Loud Is Too Loud? Found on the internet at https://noiseawareness.org/info-center/common-noise-levels/

You should replace the machine’s internal air intake filters every two years, and you can do it at home by removing the door with a Phillips screwdriver. Please check your warranty if you do your own maintenance to ensure it won’t void the contract. If the repairs seem significant, hire a professional.

A doctor’s prescription is required to purchase the CAIRE Companion 5. It is not available to rent. Learn more in our complete CAIRE oxygen concentrator review.

Customer service

The CAIRE Companion 5 is available for purchase from local medical equipment suppliers such as the Oxygen Concentrator Store. You can shop online or at their retail location in Denver.

Best Overall

Nidek Nuvo Lite Mark 5 Liter

Quietest
Price: $705.50
Maximum oxygen output: 5 liters per minute
Power consumption: 330 watts
Dimensions: 9 inches wide x 14 inches deep x 23 inches high
Weight: 32 pounds
Why we chose

We named the Nidel Nuvo Lite Mark 5 Liter as “Quietest” because at 40 decibels, users can easily engage in conversations while taking supplemental oxygen. If you want company while quietly getting the support you need, this model may be the one for you.

Pros & cons
Pros As quiet as a library Energy-efficient Built-in handle and wheels for easy transport Cons No LED screen Not suitable for people with high oxygen needs
Additional details

The Nuvo Lite Mark 5 Liter HOC is the quietest home model on our list. It operates at 40 decibels, about the same noise level you would experience in a library. [2] International Noise Awareness Day. Common Noise Levels – How Loud Is Too Loud? Found on the internet at https://noiseawareness.org/info-center/common-noise-levels/ The Nuvo Lite Mark 5 Liter has a flow setting range of 0.125–5 liters per minute. It operates at 330 watts, making it more energy-efficient than some competitors.

The Nuvo Lite Mark 5 Liter is quieter and lighter than many other options at 32 pounds, 23 inches high, and 9 inches wide. It has a handle and wheels to help maneuver around a room easily when not in use.

Safety features include a blinking red light alarm and beeping in case of a malfunction, but the model lacks an LED screen to display warning codes. The compressor automatically shuts down if this HOC becomes overheated.

You’ll need to provide occasional maintenance to your HOC to keep it running efficiently. Nuvo suggests disinfecting the humidifier bottle in a mixture of one part vinegar with nine parts water. A customer service representative said that other maintenance on this model depends on the frequency of use. Those using the device to support their COPD should replace the air intake filter every two months, and the cabinet filters every three months. You should replace the air filters every two years and can perform this maintenance at home. Please check your warranty if you do your own maintenance to ensure it won’t void the contract. If the repairs seem significant, hire a professional.

A doctor’s prescription is required to purchase the Nuvo Lite Mark 5 Liter. It is not available to rent.

Battery life: 2 hours 40 minutes to 5 hours (on Setting 1)
Dimensions: 5.9 inches wide x 2.68 inches deep x 7.2 inches high
Weight: 2.8 pounds
Why we chose

The 2.8-pound Inogen One G4 is ideal for short excursions or flights. It’s a portable oxygen concentrator you can use while on the go.

Oxygen Concentrator Store customer service

Some of the oxygen concentrators in this review are available through the online retailer Oxygen Concentrator Store. You can contact the customer service department in the following ways:

Our Reviews Team’s customer service experience

The Oxygen Concentrator store offers a chat feature, and customer service was very responsive to our reviewer’s questions. The customer service representative said most HOCs last about five years. They also recommended wiping the external vents down monthly to keep the machine operating properly.

Shipping takes about three to five business days, but Oxygen Concentrator Store also offers two-day and overnight shipping for an additional cost.

What is a home oxygen concentrator?

A home oxygen concentrator is a medical device used to provide supplemental oxygen for those with breathing conditions, such as lung cancer, asthma, or COPD. Unlike an oxygen tank, these devices use electrical pumps to filter nitrogen from the air around you and concentrate oxygen levels. You’ll need a prescription for a home oxygen concentrator, and it’s important to speak with your doctor about appropriate use.

How does a home oxygen concentrator work?

HOCs extract air from the room, filter it, and deliver purified air through a nasal cannula, a long tube running from the device to your nostrils. Those requiring a high oxygen flow, which is about 3 liters per minute or more, benefit from continuous-flow oxygen devices, according to the American Thoracic Society. [4]Jacobs S, Krishnan J. Annals of the American Thoracic Society. September 2021. Patients Choose Hypoxemia Over Social Isolation. Found on the internet at https://www.atsjournals.org/doi/full/10.1513/AnnalsATS.202106-676ED Your medical condition and prescription determine the best flow level for your needs.

You can use a HOC while you are awake or asleep. Some work well with CPAP machines to support you if you have sleep apnea.

Oxygen flow types

Stationary HOCs offer a consistent oxygen flow, while pulse flow portable models provide oxygen every time you inhale, according to a comparison of supplemental oxygen therapies. [5]Gloeckl R, et al. Respiratory Medicine. September 2019. Comparison of Supplemental Oxygen Delivery by Continuous Versus Demand Based Flow Systems in Hypoxemic COPD Patients – A Randomized, Single-blinded Crossover Study. Found on the internet at https://www.resmedjournal.com/article/S0954-6111(19)30258-6/fulltext Both machine types have different flow settings you can adjust on the concentrator. With some portable models, you may be able to change the settings from an app on your smartphone. Please check with your doctor before making adjustments to oxygen levels.

Who should use a home oxygen concentrator?

People with chronic respiratory diseases or those who don’t get enough oxygen benefit from using a home oxygen concentrator. You may need one if you have asthma, COPD, emphysema, heart failure, or other health conditions. Low oxygen levels can lead to shortness of breath, chest pain, confusion, balance issues, headache, dizziness, and other symptoms.

“For some, their health condition results in such low oxygen that they are at serious risk without supplemental oxygen. For others, such as those who have COPD and have a low resting oxygen level, supplemental oxygen reduces the risk of them developing pulmonary hypertension, and therefore improves both their quality of life and their prognosis,” said Praveen Bhatia, MBBS, a respiratory medicine physician and sleep medicine expert in Manchester, United Kingdom.

You must get a prescription from your health care provider to buy a HOC. Your doctor will determine whether you need a pulse or continuous-flow oxygen concentrator and how often to use it.

If you are often on the go or traveling, you might find a travel CPAP works better for you.

What to consider before buying

The best machine for you will depend on your prescribed oxygen needs, lifestyle, and other preferences. Before buying, you should consider a few factors:

How much do home oxygen concentrators cost?

The HOCs we reviewed range in price from $595–$2,650. The price does not appear to be related to size, as the smallest model was the most expensive. The cost varies with accessories and warranty length and coverage. The most affordable model on this list is the CAIRE Companion 5 Home Concentrator.

Does insurance cover home oxygen concentrators?

Depending on your plan and provider, private insurance may cover some or all of your HOC costs. Contact your insurance carrier before buying to see about reimbursement. Your health care provider will be required to complete paperwork and provide documentation on the medical necessity of an HOC. Your local State Health Insurance Assistance Program (or SHIP) can help if you have questions about this requirement.

Does Medicare cover home oxygen concentrators?

Oxygen machines are considered durable medical equipment (DME)Durable medical equipment (DME): Medical equipment expected to last at least three years, prescribed for in-home use for a medical reason. , so Medicare Part B may cover some of the cost of a rental HOC. For Medicare to help pay for your oxygen, your doctor will need to prescribe oxygen, prove that supplemental oxygen may improve your condition, and document that your blood oxygen often falls below acceptable levels. See Medicare.gov for more information. [6]Centers for Medicare and Medicaid Services. Home Use of Oxygen.

*Cost at the time of publication of this article. If you live in Massachusetts or New Jersey, you may see a higher price for your oxygen concentrator. These states require a licensed respiratory therapist to deliver, set up, and titrate (adjust the oxygen dose of) your concentrator.

How we chose the best home oxygen concentrators

Our Reviews Team consulted with three geriatric care experts and one respiratory therapist to learn more about home oxygen concentrators and how they can enhance users’ quality of life. Based on our expert consultations and research, we found various factors important for our readers when shopping for a portable oxygen concentrator unit, including cost, ease of use, oxygen delivery method, and more. We had all our selections medically reviewed by an expert in the field to ensure each brand and model meets our readers’ needs.

Bottom line

The best home oxygen machine for your needs will depend on a variety of factors. There are multiple options to choose from, and each brand and model has its own benefits and drawbacks. To find the best oxygen machine for home therapy use, consider the price, the amount and purity of oxygen your prescription requires, and whether noise or portability is a concern. Your doctor or respiratory therapist may have a recommendation for what type of home oxygen concentrator is best for you or if there are certain features you should look for.

We selected the CAIRE Companion 5 Home Concentrator for budget-conscious people as “Best Value.” We recommend the Nidek Nuvo Lite Mark 5 Liter if you’re looking for a quiet model. We chose the Invacare Platinum 10 Liter HOC for those with high oxygen needs. Consider the Inogen At Home 5L Concentrator if you’re looking for an energy-efficient machine. For people looking for a long-lasting model, consider the CAIRE AirSep Newlife Intensity 10. If you’re looking for an oxygen concentrator you can use on the go, our Reviews Team recommends the Inogen One G4 POC.

Frequently asked questions

Although you can purchase some oxygen concentrators online, you should get a prescription from a health care provider to determine which model would work best for you and how much supplemental oxygen you need.

The oxygen concentrators we reviewed range in cost from $695–$2,948. The only portable oxygen concentrator on this list costs the most.

A stationary oxygen concentrator is best for home use. The stationary models can provide continuous oxygen using AC power and can run all day and night, even while sleeping. Many home models have built-in handles and wheels for easy transport when not in use.

No, you cannot buy oxygen concentrators over-the-counter or without a prescription. Over-the-counter oxygen canisters are available for purchase without a prescription, but they aren’t a replacement for medical-grade prescription supplemental oxygen. Instead, these small, hand-held oxygen tanks are designed for athletic support and to ease symptoms of altitude sickness, hangovers, or jet lag.

Stationary oxygen concentrators must be plugged in to function, so you a need backup electricity source in case of a power outage. Consider getting a power generator for these events. Home concentrators can also be quite large and hard to move.
