Used Portable and Home Oxygen Concentrators

We have a large inventory of Certified Previously Owned Used Portable and Home Concentrators from the leading manufacturers and the top models. We have our highly trained oxygen technicians inspect every unit to ensure that they meet the manufactures specifications before we sell any used unit.

We thoroughly diagnose the oxygen unit and monitor it in the different stages of operator. We put any used concentrator we receive through a vigorous 12-point testing process. Some important tests we do are testing for leaks, testing for oxygen purity and testing for any irregular sound or vibration. Once the units pass all of our tests, we run the unit for 24 hours to ensure that there are no additional problems
