Here are a few more testimonials and portable oxygen concentrator reviews that have helped others decide on whether or not Inogen is right for them:

“Switching from oxygen tanks to the Inogen portable unit has been immensely beneficial to our quality of life.” – Margaret M.

“I have been using mine now since March 2012. This is so wonderful!!! I used to have to lug 3 or 4 tanks to make it through an average day.” – Sharyn T.

“Dear Inogen, I want to thank you for your great product. It has allowed me to continue to pursue all my passions of life because I can travel and play golf, hunt and fish anywhere in the world that has power or a generator.” – Dr. Michael J. C.

And this review is one of our favorites:
“My first portable oxygen concentrator was not an Inogen, and it failed me once too often just weeks before a scheduled 8 ½ hour flight from Norfolk to San Diego. I had been told that Inogen made the best POC on the market… so I called to inquire about it. When I learned that the Inogen came with a lifetime warranty, I decided to buy it, and I am so happy now that I did. I found the Inogen One G2 to be easy to use, easy to care for and able to get me from coast to coast in an airplane without the need of changing batteries! And it was so quiet that I often checked to make sure the green light that signals that it is working was on! I needed oxygen 24 – 7 during my visit to the beautiful town of Ojai CA, and I pulled my G2 around with me both through the town and up on the top of Meditation Mount outside of Ojai where I went to take photos. Thanks to Inogen, I can now look forward to more visits to California and the Southwest without having to worry about where my next breath is coming from!” – Sarah G.

    I have the Inogen one G3 POC. Am I able to sleep with it? The South African supplier indicated that it was not suitable for sleeping?

      It is approved for nocturnal use as long as it is not used with a CPAP or BIPAP.

  4. Wanda says:

    How much does this weigh?

    1. Inogen Inogen says:

      Hi Wanda, It depends on which product and whether or not you're using a single or double battery. The G4, our newest unit, with a single battery is the lightest option, at 2.8 pounds. With a single battery, the weights for our products are as follows:
      Inogen One G2: 7 pounds
      Inogen One G3: 4.8 pounds
      Inogen One G4: 2.8 pounds

  5. Susan Moore says:

    Do you have a portable machine that puts out the same liters as the home machine. I am on 4 on the home machine I believe thats liters. I was told that the portable machines are milla liters. Is that true and is a milla liter a 100th of a liter? Please reply.

    1. Inogen Inogen says:

      Hi Susan, Thank you for your question! Our portable concentrators have settings rather than liters per minute (LPM). Because each unit is digitally calibrated, the settings translate to the same approximate LPM as a stationary machine. However, we do recommend that a medical professional titrates every patient to ensure they are using the correct setting. Our G2 portable concentrator has a maximum flow setting of 6, which is approximate 6 LPM. The G3 can go up to 5, and the G4 has a maximum flow setting of 3. Please give us a call at 1-800-678-5572 if you’d like more information!

  6. Nona pike says:

    Iam in need of oxygen but I don't pass my insurance so dr can't order it do I need a dr prescription for this

    1. Inogen Inogen says:

      Hi Nona, Yes you do need a doctor's prescription, however you do not need to go through insurance if you have a doctor's prescription. We offer patients the option to purchase and own a portable oxygen concentrator. For more information, please call an Oxygen Specialist at 1-800-678-5572.

  7. Herbert Tobin says:

    I purchased my first G4 from 1st Class Medical which is the company I bought my Evergo from. I had the first G4 just a short time, 3 months or so, before I reported my problem.
    My G4 Alarm went off and read Low Oxygen or sometimes Oxygen Error. They replaced my first one free of charge so that was ok.
    Now the 2nd one is saying Low Oxygen after a short while of using it. I have only had this unit about 3 to 4 weeks. I am very disappointed!

    1. Inogen Inogen says:

      Hi Herbert, We are sorry to hear you are having some issues with your unit. 1st Class Medical is a preferred provider and they will be able to assist you further.

  8. Janet Down says:

    Will there be a backpack with storage for extra batteries coming any time soon?

    1. Inogen Inogen says:

      Hi Janet, Thank you for suggestion. I will bring the idea to our product development team so that they can investigate further.

  9. Robert E Symons says:

    I purchased a G4 and from day one it has een making a loud clicking noise. I've called service a half dozen times and they say it is normal. I think they believe is the swishing noise get when breathing. I breath two or three times before I get the loud clicking. In a group situation the people comments on how it is making tha loud clicking noise. If this company doesn't back up their products I would not recomment them.

    1. Inogen Inogen says:

      Hi Robert, The air around us is 78% nitrogen, 20% oxygen, and 2% other gases. Our portable oxygen concentrators (POCs) filter out the nitrogen and other gases in the air to produce medical grade oxygen. The clicking noise you are hearing is the concentrator expelling nitrogen and other gases. All POCs make a clicking sound as they are mechanically converting normal air to medical grade oxygen. The Inogen One G3 is one of the quietest POCs on the market. On a flow setting of 2, the noise level is 39 dBA. Please visit our FAQ page for more information: https://www.inogen.com/support/faqs/

  10. Lesa Sikora says:

    I am a very light sleeper. I currently use an oxygen concentrator at night only, but I have a 50 ft hose so I can place it in another bedroom to sleep. The pulsing and whooshing noise keep me awake. How quiet are these? I need one for sleeping only, and I don't like to cope with my heavy unit. I'd like to get one to travel with, but if it's going to be noisy, I can't use it. Thank you for your response.

    1. Inogen Inogen says:

      Hi Lesa, The higher the flow setting, the more noise a concentrator will make. However, our portable oxygen concentrators are some of the quietest POCs on the market. On a flow setting of 2, the Inogen One G3 the noise level is 39 dB. To hear an amplified recording of the characteristics of its sound, please visit: https://www.inogen.com/support/faqs/

  11. Bruce Adams says:

    What is the lowest temperature that the Inogen one G4 can operate? Can I walk outside using it when the temperature is below 0 centigrade?

    1. Inogen Inogen says:

      Hi Bruce,
      Our POC’s can be used in low temperatures. Basically, if the user can tolerate the temperature for a certain period of time, most likely the device will also tolerate. Our POC’s are built with smart technology and will advise the user (on the display screen) if the device gets to a temperature too hot/cold and give enough warning to get the device to a more comfortable environment.
      I hope this helps answer your question.
      Thank you.

  12. Heather Preston says:

    I have an Inogen G2 and have had nothing but problems….my first machine Ihad after about a year stopped giving me oxygen…I would inhale but no oxygen would come out and it got to a point where I would inhale 10 times and finally a very long burst of oxygen would come out and it did this continuously. I was finally sent a different machine (don't think it was a new one) and it started out doing the very same thing but didn't get too bad until a month later and it is now doing the exact same thing…this is a serious problem for me as I'm not getting enough oxygen while I'm out and I'm not sure what to do about this.

    1. Inogen Inogen says:

      Hi Heather, Please call our Customer Care department at 1-877-466-4364 so we can help you troubleshoot.

  13. Yvonne Enticott says:

    My husband uses the Inogen g3 can he use it overnight please

    1. Inogen Inogen says:

      Hi Yvonne, Yes the Inogen One G3 can be used day or night, and should be used as prescribed. Most doctors prescribe 24/7 oxygen and if that is your husband's case, he should use his Inogen One G3 at night.

  14. Laura Bauer says:

    Hello. I use the Inogen One. The largest concentrator that goes up to 5lpm. I currently use it on setting 3 as needed. Yesterday my display alarmed with a readout of "low oxygen". I no longer have my manual for reference. What does it indicate? It was on #2 setting at the time. I turned the machine off for a while. Now it appears to be ok.

    1. Inogen Inogen says:

      Hi Laura, When you say that you have, "the largest concentrator that goes up to 5 lpm" are you referring to the Inogen One G3? If so, according to page 25 of the Inogen One G3 User Manual an Oxygen Low message alert means that the concentrator is producing oxygen at a slightly low level (<82%) for a period of 10 minutes. If this condition persists, please contact us at 1-877-466-4364.

  15. Sue says:

    Every time I inhale there's quick a sucking noise in my cannula. Is this normal? I have a One G3

    1. Inogen Inogen says:

      Hi Sue, How long have you had your Inogen One G3? If you are new to portable oxygen concentrators, you may just be hearing your own breath coupled with the "puff" sound of the bolus. If you have had your Inogen One G3 for a while and this issue just started, you should contact our Customer Care Department at 1-877-466-4364.

  16. Marie says:

    Above, Robert Symons complained of the distracting loud clicking the G4 makes. You replied with stats on the G3? I also am interested in whether the G4 is noisier than other units – whether Inogen or not – because I actually sent my first back and got a replacement because of the noise… Unfortunately, the replacement unit is ever MORE noisy! I can't find any information about the G4…

    1. Inogen Inogen says:

      Hi Marie & Robert – My apologies! The Inogen One G4 is 40 dBA* – 1 dBA higher than the Inogen One G3.

  17. Robert hicks says:

    I have seen you product on the internet, and I am tired of not being able to leave my room without dragging A tank along.

    1. Inogen Inogen says:

      Hi Robert, We totally understand how you're feeling! Heavy tanks are a burden. Let us talk you through our different portable oxygen concentrators. Please call 1-800-374-9038, to speak to an Oxygen Specialist today.

  18. Mark Emden says:

    Little is said about batteries. What type are used? Are they rechargeable?
    Where do I get them? That is their cost?

    1. Inogen Inogen says:

      Hi Mark, Our batteries are rechargeable lithium-ion batteries. There are two different types of batteries (a single and a double) available for the Inogen One G4 and the Inogen One G3 portable oxygen concentrators (POCs). Double batteries give the user about twice the battery life of a single battery. On a flow setting of 2, the Inogen One G4 single battery gives up to 2.7 hours of battery life. On the same setting, the Inogen One G4 double battery gives up to 5 hours of battery life. On a flow setting of 2 on the Inogen One G3 POC, the single battery gives up to 4.7 hours of battery life, and the double battery gives up to 10 hours.

  19. Deb says:

    I currently bleed in 1.5liters continuous flow oxygen from an Everflo Q into the line for my Res Med VPAP machine at night. But the Everflo is too heavy to travel with.

    I also use a Inogen G3 to fly. Can I use my G3 for overnight oxygen with the VPAP machine?

    1. Inogen Inogen says:

      Hi Deb, Unfortunately, you cannot use the Inogen One G3 with a CPAP or VPAP device. However, our Inogen At Home stationary concentrator is compatible and was designed to fit under airline seats for this very purpose. For more information about the Inogen At Home stationary concentrator, please visit: https://www.inogen.com/product/inogen-at-home-oxygen-concentrator/
