Oxygen Concentrators

Open Box Medical specializes in used oxygen concentrators. For many of us, breathing in oxygen is so easy that we don’t even realize we’re doing it! However, for those with respiratory problems, such as COPD and emphysema, breathing can cause massive distress to the individual. Oxygen supply is a priority for Open Box Medical, hence why we provide used portable oxygen concentrators at low and affordable prices. Oxygen Concentrators are machines that filter regular room air and convert it from the average 21% oxygen to nearly 95% oxygen, increasing and improving your overall oxygenation.

In addition to used oxygen concentrators, Open Box Medical carries refurbished Open Box, and new oxygen concentrators. Regardless of the whether our Oxygen Concentrators are used, refurbished, or Open Box, we don’t sell anything unless it is thoroughly inspected by one of our highly skilled technicians. Open Box Medical offers a minimum of 30-day Warranty on all our Oxygen Concentrators.
