  1. Excellent Service and Price

    Posted by Jay N. on 11th Jul 2019

    I purchased an Inogen G3 roughly 4 months ago and so far seems to be working great for me. After speaking with my doctor and doing a lot of research on the internet I finally found the folks here at Portable Oxygen Solutions. Todd and his staff are top notch professionals and made me comfortable with such a big purchase. I highly recommend anyone looking to buy a POC should give these guys a call. You will be very glad you did. My guess is they also will save you several hundred dollars.

  2. Good buy

    Posted by Frank on 19th Jun 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.

  8. 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.

  9. 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.

  10. 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.
