Are refurbished oxygen concentrators safe? What "refurbished" has to mean before we'll sell one

Part of the series: The Complete Oxygen Concentrator Guide

A 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.

A concentrator is a good refurbishment candidate for the same reason a quality watch is: it's a mechanical system with known wear points and measurable output. The wear lives mostly in the sieve beds, filters, and battery; the output — oxygen concentration at rated flow — is directly testable. 'Refurbished' done properly means the unit was inspected, its consumable wear items addressed, and its purity functionally verified against spec before resale. If a seller can't describe that process, that's not refurbished; that's used.

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.

Two guardrails apply regardless of seller: the prescription requirement is identical for refurbished units — Class II is Class II — and returns should work the same as for new. Ours do: refurbished devices carry the same 30-day return window (with the same $75 restocking fee) as their new counterparts, because a refurbished machine that can't survive a return policy wasn't refurbished.
