  1. Reliable

    Posted by Marty B. on 20th Mar 2016

    The Freestyle 5 has been a reliable portable oxygen machine and I trust this unit. I do wish the internal battery lasted longer but I do have an extra battery to help. I mostly used the machine while driving to visit my relatives and I can plug the unit into my lighter on my car. Works great!

  2. Lightweight High Flow Portable Concentrator

    Posted by Jill N. on 8th Jul 2015

    I really like my new Freestyle 5 POC. I was surprised at just how lightweight it is and quiet, too. I am thrilled that I no longer feel confined to my home and can now travel to see my family. Todd was absolutely wonderful in helping me with all my questions and he offered me the best price I could find. Thank you, thank you!!

  3. Life Changing Equipment

    Posted by Greg U. on 2nd Jan 2015

    I have had my Freestyle 5 for a few months now and I couldn't be happier. This product meets my needs and allows me to visit my family out of town very easily. I just plug it into my car and off I go. I no longer worry about hauling tanks with me. It is very simple to use and light enough for me to carry, too.

  4. Finally, a respiratory company that understands my needs

    Posted by John F on 29th Jan 2014

    I am sooo happy with my Freestyle 5 portable oxygen concentrator. I feel like I got the best price on the internet from a company who knows how to take care of a customer!!

  5. This unit will change your life

    Posted by William H Grant on 28th Oct 2013

    I don't see how anyone can tote an oxygen tank around to the grocery, church or restaurant. I recently had lunch with my sister and she carried 2 large tanks. I couldn't do it and instead would just stay home. This machine changes all that. It is very portable and works very well. The reason I only gave 4 stars is the battery. The manufactured overstates the lenght of time the internal battery will stay charged. I only get 1 1/2 hours out of mine. The belt adds a couple more hours so it really has not been a problem. The other con I have is the latch on the carry case is spring loaded and that failed after a couple of weeks. You just have to carry the various electrical cords around when you go anywhere. If you're looking for something that looks non medical and easy to carry around, and works to provide the necessary oxygen, this is your unit.

    I also want to say Portable Oxygen Solutions is first rate. They did everything they said thy would and overnighted the unit to me when everything came in. First rate.

  6. Nice portable oxygen machine

    Posted by Jerry on 24th Sep 2013

    This is a very nice product. I need 4 liters of oxygen and this is one of the most reliable small concentrators that have found that offers me this much oxygen. Thanks for Airbelt Gift this really gives me more time away. I am considering that backpack accessory you told me about.

  7. Tiny Little Oxygen Maker Works Great

    Posted by Dolores on 7th Aug 2013

    I never thought I would find an oxygen maker that's this small and portable. The FreeStyle is a really nice change from my old stationary model. I felt chained to the couch with that thing. The FreeStyle frees me up to move around again, so I can spend more time with my family.

  8. Sturdy Travel Oxygen Solution

    Posted by Unknown on 18th May 2013

    I needed something to turn to for travel oxygen, and this product delivers. It's simple and looks almost like an accessory, so I feel as comfortable and active as possible. There are several power options depending on the setting; the flexibility is wonderful!
