Bottom Line

Inogen® designs and sells oxygen concentrators including two models of portable oxygen concentrators and one in-home oxygen concentrator. All Inogen® oxygen concentrators meet FAA standards.

Inogen’s industry-leading warranty is one of the reasons it’s one of our top picks for Best Portable Oxygen Concentrators. Its proprietary Intelligent Delivery Technology delivers oxygen within the first 400 milliseconds of inhalation when oxygen has the most effect on lung gas exchange. Intelligent Delivery Technology received clinical study validation for providing the necessary oxygen levels to most patients during any activity throughout the day and all sleep phases. An Inogen One portable oxygen concentrator can simplify life by replacing all oxygen sources for most people requiring this therapy.

Inogen’s portable oxygen concentrators require no tanks to refill or replace and no regulators. The company offers “oxygen therapy on your terms” because when you switch to an Inogen One, you no longer need to plan your week around oxygen tank deliveries and the insurance, copays and other bills that come with ordering tanks.

The Inogen One portable oxygen concentrator plugs into a wall outlet or DC car outlet for power, or use the rechargeable battery when walking around the house or the town. Inogen makes traveling with a POC much easier compared to traveling with tanks, and both Inogen One models are approved for use onboard all U.S. airlines. Inogen portable oxygen concentrators come with a 30-day risk-free trial (purchase only, restocking fees may apply), and a three-year to lifetime warranty with the bundles discussed below.

Pros

  • Lifetime warranty (with Freedom Bundle or Package)
  • Complimentary clinical services from licensed nurses and respiratory therapists
  • An all-in-one solution for stationary, portable, and travel use, day or night
  • 30-day free trial (purchase only, restocking fees may apply)

Cons

  • Insurance may not cover a portable oxygen concentrator

Inogen Portable Oxygen Concentrator Cost by Model

Choosing between Inogen portable oxygen concentrator (POC) models is uncomplicated with Inogen’s small but powerful line of products. The Inogen One comes in two models: the G4 and the G3. As the name implies, the Inogen At Home is meant for use around the house with no battery power, but is still very lightweight when compared with most home units.

Inogen Freedom Bundle and Packages

Both the Inogen One G4 and G3 offer money-saving Freedom Packages with extra batteries and a lifetime warranty.

Without a bundle or package, you get a three-year warranty, and Inogen One models include a single-cell battery.

Inogen Portable Oxygen Concentrator Accessories

Inogen offers a full line of accessories for both portable oxygen concentrator models at very reasonable prices. You can buy a carry strap ($13.95) or hip bag ($59) for the Inogen One G4. Accessories for both the G4 and G3 include:

  • Rechargeable Lithium-ion Batteries: Single ($325), Double ($495), External Charger ($285)
  • Power: AC power supply ($79 to $149), DC cable ($65)
  • Filtration: Particle filter ($11.95 to $21)

Where to Buy Inogen Portable Oxygen Concentrators

Inogen sells directly via the company website, over the phone and through authorized resellers. You will find all pricing and product details on the site.

The company also rents portable oxygen concentrators, with Inogen One G3 rentals being covered by many insurance companies and Medicare as durable medical equipment. While Medicare or most private insurance benefits don’t include the Inogen One G4, many find the cost worthwhile for a portable oxygen concentrator weighing under three pounds, so it can be carried in a backpack, handbag, or on the hip. If you have Medicare Supplement or Medicare Advantage insurance, you may find you have partial coverage.

Inogen Complaints

Inogen is accredited with the Better Business Bureau with an “A+” rating. ConsumerAffairs ranks the POC provider in their top five choices, and Top10Reviews calls the G4, “one of the lightest oxygen concentrators available on the market today.” Trustpilot has nearly 3,100 consumer reviews to date with an average 4 out of 5-star rating. The majority of Inogen G3 customers leaving comments in the COPD Foundation online community are overwhelmingly positive.

Unit functioned well for a few months, but when replacement was required the customer service response was abysmal. Initially were told to expect a unit to be sent via overnight air delivery and arrive a week ago, it STILL has not arrived. Despite multiple phone calls per day, requests for escalation to higher levels within CS team, etc, all we've been able to get out of them is "we'll email shipping and have them expedite". Turns out there are CS groups in CA, OH, and TX. They do not talk to each other, and claim to have no telephone access to shipping or their managers. This level of corporate incompetence would be infuriating if I was trying to buy lead pencils; the fact that it is equipment that literally keeps someone alive should make it criminally negligent. STAY THE HELL AWAY FROM THEM!!!

Inogen is great. When it works. And for those that need an oxygen machine know the importance of the machine actually supplying oxygen. My mother needs oxygen 24/7. These machines break regularly, she has multiple because of this. When they do break, getting replacements are near impossible.

Customer service is rude, they have laughed at us multiple times while pleading to get a new machine. For this newest incident it has been 7 days since we first called about a new machine. We have been promised it would be overnighted every single day. We have called each day stating we haven't gotten it. And they say they'll get another overnighted and it never shows. We finally received tracking information.

After 7 days. And we're told we are supposed to wait 4 more days before it will arrive. Because with Inogen. Overnight means ground shipping. We have asked to speak to supervisors only to find out who we were transferred to wasn't a supervisor, multiple times. we are now having to take my mom to the hospital. Which will be very pricy and interfere with flight plans I made months ago to go to a family wedding.

I am not at all pleased with how this company runs things. It is very unprofessional and puts people's lives at risk. We will be contacting local media about these incidents as well and sending inogen any and all medical bills acquired from the hospital.

I ordered a G5 with Freedom package 3 and a Home unit direct from Inogen (No 3rd party vendors for me). Prompt delivery. Sales representative, technical support, and customer service were the best. My charger was questionable and Inogen sent a new one immediately with no complaints or hesitations. Works well at home and away and I have no complaints. The complaints I read are probably from 3rd party vendors. A friend of mine has a home unit and states that the vendor will not offer to fix or repair and will not return phone calls. Deal direct with Inogen for a satisfactory experience. 5 STARS all the way.

Have been trying to get someone to return my call and waste of time and money. Mailed all the paperwork to the FDA for help on getting a refund and return this piece of useless equipment. Would not tell anyone to purchase it is horrible. The 1st one quit and I was without oxygen for over 2 plus hours and had my elderly mother with me. Was sent a used one that had 259 hours on it and it lasted a week now here I am again trying to get service. This is my 3rd complaint and I will find some government officials to go to and maybe get some place. I don't want your product I want my money back. I don't trust your product it has been proven to me it is not safe for my needs. It was also sent to me WITHOUT A DOCTOR'S ORDER.... this will look good on your audit I am sure.

After reviewing at a variety of sites decided to buy a G4 for myself a few months ago, directly from Inogen. I upgraded to lifetime warranty package. Love this little thing. I use it 24 hour a day. We have taken it on flights with no problem. Use it every time I am in the car and while golfing in the fanny pack. Called customer service once at 2am and it rang twice before picked up and problem solved over the phone. I cant understand why the other people all have problems, I can only think they didn't buy from Inogen but one of the way too many companies out there.

Purchased G3 model 8/2018. Has erratic shutdowns needing reboot. Now find the Warranty is limited and has costly repercussions. First mobile dependency (the reason the unit was bought) is limited since the seller LPT will rent a low cost loaner for $330 which is out of my ability to pay. Second the unit may be gone for 7-10 days plus transit time for what may be a software update at a cost of $90 for transporting. Third if the fix is not complete the costly and time consuming process repeats. Factory customer service at Inogen advised that if bought directly from the factory they at time supply a loaner for $150 and depending on the repair the shipping back and forth may be waived. So I was penalized by buying at a dealer. The last issue is the "Low Cost Loaner program" …..reassures you that you will have oxygen on you no matter where you are. Not if you do not pay the $330 at LPT Medical. Am selling the unit and going back to more reliable, Medicare covered, and available for service 24 hours a day.

The Inogen's battery is 14.4 volt, but the automobile charging thingys are only 12 volt. Unit does tend to overheat, but turning it off for a bit to cool down works. Keeping it out of the sun in the car helps keep from overheating.

Very misleading. This isn't for a person that has lung disease!! This should taken off the market because it only last a very short time!! Never will I say this is a great replacement for oxygen when it dosent help a person that can't breathe. Waste of the money!!!!

For the past 4 month I’ve been trying to get them to help me, it’s so bad I don’t even get a return call back. Waiting and waiting to get the help I need. My doctor is trying to get another company at this time.

My Inogen one keeps overheating after only using it for 2 hours. This happens while plugged to electric. Thank goodness I had oxygen tanks with me in the car... I wasn’t at home when it happened. The machine was sent to manufacture for repairs but came back in same shape. I noticed in many reviews that this has not been a problem with them.
