Catalog: Recertified and Pre-Owned Oxygen Concentrators

Safe, reliable, and efficient; pre-owned and recertified portable oxygen concentrators are a specialty item that can make the difference between a nice day out on the town, or a difficult, tiring day with your loved ones.

Portable oxygen concentrators are a luxury, but what’s surprising is how affordable they are. In the past, as early as the 1950s, those requiring supplemental oxygen had to deal with cumbersome tanks that only supplied a finite amount of oxygen.  As a result, the tanks needed to be replaced continuously, increasing the cost of the therapy. This sort of technology was something only the wealthy could afford.

Oxygen concentrators, on the other hand, were developed to use the existing air in an environment and convert it to medical grade oxygen. Now patients have an infinite supply of oxygen as long as there is a steady power supply. Rather than continuously paying for replacement tanks, there is only the upfront cost.

Advances in oxygen concentrators mean that they now offer oxygen delivery methods more specific to a patient’s needs. While oxygen tanks only provide a continuous flow delivery, oxygen concentrators offer both continuous flow as well as pulse-dose delivery methods, thereby conserving more oxygen. Since oxygen concentrators convert air into oxygen instead of storing it, the risk of a leak with the potential to cause a fire decreases, especially in the case of the pulse-dose delivery method.

With the demand increase and the progress of modern technology, not only are oxygen concentrators portable, they are also lightweight (weighing around 5 pounds or less), affordable, and better than ever.

The pre-owned and recertified portable oxygen concentrators at US Oxygen Sales are tested and maintained to be the best at very affordable rates. Be wary of companies or individuals who are trying to sell oxygen concentrators at a fraction of the cost. They may only clean the oxygen concentrator and check to see if it still operates before putting it back on the market. Oxygen concentrators need to be regularly maintained since individual parts, such as cannulas, gross particle filters, and compressors, have limited life spans. These companies sometimes offer their own warranty rather than the manufacturer’s warranty. This type of warranty is often unreliable. At US Oxygen Sales, our certified technicians thoroughly inspect each pre-owned concentrator to make sure they are in perfect working order and we only offer warranties supported by the manufacturers.

US Oxygen Sales has affordable pricing on a vast selection of pre-owned, recertified portable oxygen concentrators to meet the financial needs of all of our customers. Nothing compares to that feeling; that feeling of getting your independence back or regaining the peace of mind when a loved one is getting the quality of medical treatment they deserve.
