Everything like ads The VT-1 is everything advertised and specified on the website. I have tested both flow and O2 concentration percentage and they match the specifications. I did notice power consumption appeared to be only 50 watts when using 12-14v battery/car which is excellent and better than the 75 watts specified. I am thinking the 75watts is with the 120v AC power supply and you get some inefficiencies with the converter/adapter. The unit does live up to the 58db sound level specified, about the level of normal speech.

A quality oxygen concentrator I needed a oxygen concentrator and went the usual route renting a less than quality machine supplied by the local medical company. The machine was old, heavy and noisy a big energy waster to say the least. Varon Oxygen Concentrator fit the bill. Very quiet easy on energy and light no wheels needed. I could not be more happy with my purchase. Jim S

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.

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.

Response time for inquiries was quick… Response time for inquiries was quick and thorough. We did initially get a defective concentrator. The process for return and replacement was easy. As a retired corporate QA person, things do go wrong with products. It is the response to the issue that defines trust. Varon responded well.
