Excellent! I could not be an effective commercial truck driver without this device in my SEMI. Everyday, I deal with altitude air pressure changes, dust, and engine exhaust exposure which effect my brain health during the 14 hour work period. Oxygen compressed air canisters aren't allowed so this is the only solution. (CO) Carbon Monoxide (CO) A colorless, odorless gas resulting from the incomplete combustion of hydrocarbon fuels.

Works as advertised Unit came in perfect condition, packed well. Instructions were easy to follow. Unit and remote work as they should. Oxygen level dropped too low while I was sleeping which is why I purchased the unit. This unit has alleviated that problem. I would not have a problem making another purchase.

I own 2 VP-1s I own 2 VP-1s; 1 VH-1; and two VH-3s. The value for the price was initially excellent. But after a few months the VP-1 started beeping, meaning "low concentration". I cleaned everything, still beeps. I switched to new tubing, still beeps. There is nothing wrong with the air flow, but it still beeps. So the good investment is now a waste of $600. I tried the customer service phone but mailbox is full. I filled out the service form yesterday, no response so far.

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.

I have been using my Varon Oxygen 2 months now.… I have been using my Varon Oxygen Concentrator for over a month now. I am beyond satisfied with this product. I would highly recommend this concentrator to any one who is looking for one. The price is right and the quick delivery.
