Very surprised to see positive reviews… Very surprised to see positive reviews of a company I know to be deceptive. Bait and switch is how I’d characterize them. Their advertising goes on and on about 90% oxygen concentration but their entry level is only 30% concentration which is not something they tout prior to the sale. Be very cautious when dealing with these folks, they will ship you something from China which you will never be able to return and they will offer you a small credit to shut you up.

Great Portable at a Great Price I’ve had my Varon portable concentrator for a couple weeks now and I’m very pleased with it. I’ve borrowed a friend’s more expensive concentrator before and my Varon performs just as well and costs a lot less so I’m happy. The customer service is also very good. I really believe this company cares about its customers.

Very quite device It took me awhile to use it I wanted to get extra O2 tubes and something to clean them with. It is quieter than I thought it would be - I was using the nasal cannula wrong no instructions for that - I love the machine it helps me almost every night, so glad I have it - I would suggest a different hose connector though one that is tapered so it is easier to put the tubing on bless youall.

Needed a concentrator that I could count on.... I was in need of a portable oxygen concentrator and the price was so much to consider, I looked for a long time and then came across the Varon, I weighed all the options and hoped it would do what it said it would hoping the levels of oxygen would be enough. So I purchased it and when I got the machine I had a doctors appointment, took it to the appointment and the doctor checked it out, also put the oxygen level taster on my finger, we did about 5 to 6 laps around the office first at a normal walk then faster up to a very fast speed walk and keep checking the levels and they stayed up to 92 to 93% at all the time we did this. I have used tthe machine for 1 1/2 months now and very pleased with it. The only thing is I wished they would put a longer life battery to the machine without having to purchase the longer life battery, because being on a very low fixed income money don't come easy. but other than that I am very please with the machine.

Good quality and price. I have had my unit for a month and am very pleased with it. It was packed well and delivered on time. It has really helped me with both breathing and anxiety. I would recommend Varon if you need an oxygen concentrator.
