  3. Best portable oxygen generator ever!

    Posted by Keith Graves on 22nd Mar 2019

    The Inogen G3 is the best portable oxygen concentrator on the market. It does everything that I need and is so simple to operate. Also the staff at Portable Oxygen Solutions was so helpful in providing me information so that I could choose the best solution for my requirements. I would definitely do business with them again.

  4. Inogen O2 concentrator

    Posted by aaron copley on 17th Mar 2019

    Although there was a little mix up on original delivery time. All is well. The use of the Inogen G3 is very easy and is much better than lugging around my old one. I am very happy with the product. Very good customer service.

  5. fabulous company service

    Posted by Mary on 18th Dec 2018

    I just received my G3 yesterday so I can't give a fair review of the system, but with a few simple steps I was up and running.
    When I was looking into portable systems I had a lot of questions. The gentlemen here answered all my questions with courtesy and respect no matter how dumb my questions were. They were very knowledgeable and helped me compare brands so I could make a informed decision. There are many companies out there that could take a lesson from these gentlemen on how to treat customers like real people not just a number.
    Keep up the good work!!!
    I never felt pressured and when I did place my order it was shipped promptly, and I had it with in 2 days.

  6. love this device

    Posted by Unknown on 31st Oct 2018

    So happy with this G3 portable oxygen concentrator. It is expensive, but the freedom it allows is worth it.

  7. The Inogen G3 is great!

    Posted by CClaudia on 21st Jun 2018

    I have been very pleased with my new G3. It is everything that it is advertised to be. I took it on a long cruise and it functioned 24/7 without any problems. An extra bonus is the people at Portable Oxygen Solutions. They are very professional, knowledgeable, and friendly. Get one today.

  8. Much better than conserver tanks

    Posted by Gerry on 7th Jun 2018

    I have had the G3 for a month, and am very pleased with it. The one week trial period was adequate to evaluate it. I was concerned about the sound level which I initially found higher than expected. I now consider it to be just fine at a setting of 3. Working with Jeff Dewberry was a very good experience, and after a lot of research I believe that Portable Oxygen Systems is the best place to buy this device. The price is several hundred dollars less and their service reputation is great.

  9. Very good

    Posted by Robert L on 26th Mar 2018

    Unit is great. I play a lot of golf and looking forward to getting out to the course.

  10. Great Portable Concentrator

    Posted by Unknown on 6th Mar 2018

    This is by far the best portable I have used.
