Buying a Refurbished Portable Oxygen Concentrator

A portable oxygen concentrator draws in air, filters out nitrogen, and delivers concentrated oxygen through a nasal cannula — giving you the freedom to move around the house, travel, and stay active without heavy oxygen tanks. Refurbished units make that freedom more affordable. Every refurbished oxygen concentrator we sell is inspected, cleaned, and function-tested by our team, backed by a 1-year warranty, and requires a valid prescription. If you're unsure which model fits your prescribed settings or travel needs, our support team is happy to help you choose.

FAQs

What does "refurbished" mean for an oxygen concentrator?

A refurbished oxygen concentrator is a pre-owned unit that has been fully inspected, cleaned, and function-tested, with worn parts replaced as needed. Each one is verified to meet its original oxygen-output specifications before we ship it, and is backed by a 1-year warranty.

Do I need a prescription to buy an oxygen concentrator?

Yes. Oxygen concentrators are prescription medical devices in the US. Your prescription specifies the oxygen flow setting and delivery type you need, and our team can guide you through submitting it after you order.

What's the difference between pulse dose and continuous flow?

Pulse dose concentrators release a burst of oxygen each time you inhale, which conserves battery and keeps the unit lightweight — ideal for active, on-the-go use. Continuous flow concentrators deliver a constant stream of oxygen regardless of your breathing, and are often prescribed for higher-need or nighttime use. Your prescription will indicate which you require.

Are refurbished oxygen concentrators reliable?

Yes, when they're properly refurbished by a reputable supplier. Every unit we sell is tested to confirm it delivers oxygen within its rated specifications, cleaned and sanitized, and covered by a 1-year warranty — so you get dependable therapy at a lower cost than a new unit.
