Used Portable Oxygen Concentrators
Brand-new portable oxygen concentrators (POCs) routinely list for $3,000 or more, yet many shoppers discover thatpre-owned or refurbished units can deliver the same therapeutic oxygen for roughly half that cost. Retailer LPT Medical reminds readers thatnew devices are pristine but pricey, whereas refurbished machines have undergone major component replacements and still cost hundreds less—an approach that makes sense for anyone on a budget who still wants reliability. The company even notes that renting is only smart for very short-term needs, urging buyers to weigh total cost of ownership carefully; see how LPT frames the decision in their article on whether to buynew, used or refurbished portable oxygen concentrators.
The advantages at a glance

- Warranties that often run 90 days to 3 years
- Thorough reconditioning (filter changes, compressor tests, software resets)

Quick checklist before you click “Buy Now”
✅ Confirm your prescription flow requirements (pulse vs. continuous, L min)
✅ Ask for the device’s total run hours—look for <3,000 h on smaller portables
✅ Verify warranty length and who covers repairs (dealer vs. manufacturer)
✅ Inspect battery capacity (many sellers will bench-test on request)
✅ Ensure accessories match your lifestyle (shoulder strap vs. backpack, extra battery for day trips)
✅ Request a return window—Pure O2’s 7-day policy is a good benchmark
✅ Compare total price plus shipping; remember Respiration Nation ships free over $1,000

Used portable oxygen concentrators can be game-changing—restoring mobility without wrecking your budget. By focusing on reputable refurbishers, demanding transparent testing records, and choosing a model whose specs match your prescription and lifestyle, you can stride out the door with confidence, lighter baggage, and heavier peace of mind.
