Our Used Oxygen Concentrators are ideal for users who are searching for a more affordable alternative instead of purchasing a new oxygen concentrator. There are their own advantages of whether buying a brand new or a used oxygen concentrator with good quality. An important point in purchasing a used unit is that the price is very affordable. We can provide you the used units with the same high quality and service. 

Our technical experts conducted a quality inspection on these items. Each of our units has been cleaned and thoroughly tested to ensure the highest level of operation. We are not only refurbished machines, and the only downside is that there may be some scratches on the outside and the outer box is slightly damaged.

Attention: Because of the location of our warehouse, the used oxygen concentrators are only available in the United States.
