  2. Such a small portable oxygen concentrator

    Posted by Peggy on 3rd Feb 2014

    I am so happy with my Airsep Focus concentrator! This unit is so small and inconspicuous that others hardly know I have it!

    This portable oxygen concentrator truly fits my active lifestyle. Portable Oxygen Solutions is a first class company and were, by far, the most helpful of any company I spoke with regarding portable concentrators for sale. Price was the best I found online and service is top notch. Highly recommend buying a portable concentrator from this company.

  3. Great Oxygen Concentrator For Me!!

    Posted by Cindy on 6th Nov 2013

    I recently received my Focus Portable Concentrator from you and it is everything you said it would be. It is small, quite and works well for me on the go. I will recommend anyone on oxygen to do business with you. Thank you for answering all my questions even on the weekend!! I can honestly say that no other company took the time to fully discuss my situation and what I was looking for. Thank you so much for your guidance!

  4. Prolific Portable Oxygen Concentrators

    Posted by Cheryl on 3rd Oct 2013

    I was stunned that the Focus Portable Oxygen Concentrator is this small and lightweight. It is a fantastic oxygen machine for active people like husband. This portable concentrator is not much bigger than the size of my hand and was very easy for my husband to use. It's extremely mobile because it just weighs about 2 lbs! Great oxygen machine for everyday life!

  5. New to oxygen

    Posted by Linda on 26th Sep 2013

    I was recently diagnosed with COPD. I am a new oxygen patient. When they came out to my home and delivered a bunch of oxygen tanks I figured there had to be a better way. Thank you Portable Oxygen Solutions for all your help in getting me the oxygen equipment that works better for my busy lifestyle. The Focus has allowed me to continue to do the things that I really like to do!! I don't have to carry heavy tanks and I'm not worried about running out of oxygen.

  6. Light and Wonderful Oxygen Maker

    Posted by Gary on 7th Aug 2013

    I couldn't go anywhere without an oxygen machine. It was too risky, but I was very depressed about being stuck at home. I'm glad I was able to afford the Focus. It only weighs a little over two pounds, so it's no problem to carry with me. It gives me a dependable supply of oxygen so I can actually live my life. One of the best purchases I've made. Thanks Jennifer from Portable Oxygen Solutions!!

  7. Smallest Portable Oxygen Concentrator I've Ever Seen

    Posted by Unknown on 28th Jun 2013

    This is one tiny portable oxygen concentrator. I'm used to wheeling these around or carrying them in a backpack. But the Airsep Focus can actually fit in the palm of my hand. It comes with a lot of useful accessories, too, including a carrying case and extra batteries. The concentrator is great at delivering oxygen just when I need it. I can actually travel, thanks to the tiny size of the concentrator.
