Reasons to purchase a used portable oxygen concentrator
At Main Clinic Supply, we understand that one of the primary reasons patients are hesitant to purchase a portable oxygen concentrator is that these items tend to be costly. While many use insurance to help with a purchase, this doesn't always reduce costs enough to avoid being a burden for some users. Choosing a used model is a great way to save money and still receive the critical oxygen a patient needs to keep up activity.
| Benefit | Explanation |
|---|---|
| Multiple flow rates for less money | Portable oxygen concentrators come in two varieties: models with pulse flow settings, and models with both pulse flow and continuous (or constant) oxygen flow settings. While pulse flows make for a higher level of portability, continuous flow settings have distinct advantages for overnight use and for those with higher oxygen requirements. Having both flow rate options often drives up prices — purchasing used portable oxygen concentrators lowers prices significantly. |
| Just as dependable as new | At Main Clinic Supply, we're an authorized sales and service center for every major brand of portable oxygen concentrator. When we receive a used portable concentrator, we replace all filters, sanitize the device, and update all software. We often achieve higher oxygen concentrations than when they were fresh off the line. |
| It's sustainable | Purchasing a used portable oxygen concentrator is a great way to reduce electronic waste. Buying pre-owned is more environmentally sustainable, and it helps reduce the need for new manufacturing. |
| Immediate availability | Sometimes portable oxygen concentrators can be in high demand, and when this happens, new models can be on backorder. Used units are always available. |
| Accessories often included | Many times, when purchasing a portable oxygen concentrator, patients receive just the unit and nothing else. At Main Clinic Supply, we often include used portable concentrators as part of bundles — the patient receives continuous-flow night units, travel bags, and travel cases. These bundles are typically much cheaper than buying a new concentrator and purchasing accessories piecemeal. |
What customers are saying about Main Clinic Supply
"I called Main Clinic Supply because I was interested in purchasing an oxygen concentrator machine for home. Since I had such good luck with them when I purchased a portable oxygen machine (Inogen One G5) also with Dylan's help, I figured I'd go to them for this too.
I researched concentrators first to get an idea of pricing and features offered, but I had other questions that Googling couldn't answer. I wanted something that was quiet, reliable, easy to operate and maintain, and durable.
Dylan made two recommendations and after further discussion, I decided on the OxyHome model. I couldn't be happier."
— Kathleen
"Great overall experience. From the hook of their website to pricing and email/phone responses as well as order process and follow up. Delivery was on time and product presentation was perfect as received. Leo was fantastic. Don't buy from anywhere else."
— Carl
"I have been with Main Clinic for eight years. Courtney, Ricky, and Leo have all been wonderful to deal with. Obviously service has been impeccable. My Inogen machines (G3, G5, and At Home Concentrator) are stellar."
