Are refurbished oxygen concentrators safe? What "refurbished" has to mean before we'll sell one
Part of the series: The Complete Oxygen Concentrator GuideA refurbished concentrator done right is inspected, purity-verified, and hundreds of dollars cheaper. The word does a lot of work — here's what it has to cover.
Yes, when "refurbished" is done properly: the unit is inspected, its wear items (sieve beds, filters, battery) are addressed, and its output purity is functionally re-verified against spec before resale. That's a testable process, not a marketing word — if a seller can't describe it, that's not refurbished, that's just used. Every refurbished unit CIRRUS sells carries the same prescription requirement as new.
The price case is straightforward from our own shelves: a refurbished Drive iGo2 portable at $1,095 against $1,995 new, or a refurbished Philips EverFlo at $395 against $749 — roughly 45% off for machines verified to run in spec. For a backup unit, a night-side second machine, or a first machine while you learn your real usage patterns, that's the strongest value in oxygen equipment.
What you trade is warranty runway and, sometimes, battery freshness. Warranty terms on refurbished units vary unit by unit in ways new-product warranties don't, so ask for the exact terms on the specific machine before ordering — our concierge team quotes them per unit rather than printing a blanket number, because a blanket number would be fiction. Batteries are rated in charge cycles, and a refurbished portable's battery may be mid-life; factor a future battery purchase into the comparison if you'll run on battery daily.
One guardrail applies regardless of seller: the prescription requirement is identical for refurbished units — Class II is Class II. All sales are final on refurbished units just as they are on new ones, which is exactly why we quote warranty terms per unit up front rather than leaving fit or condition questions for after the sale.
