Is a Refurbished CPAP Machine Safe to Buy?

By Yash, RRT — Licensed Respiratory Therapist & Owner, MyRespCo

This is the first question almost every patient asks when they discover that refurbished CPAP machines exist. And it's the right question to ask. The short answer: yes, a refurbished CPAP machine is safe to buy — but only when you know what to look for and who you're buying from.

What Makes a Refurbished CPAP Safe (or Not)

The safety of a refurbished CPAP machine depends entirely on the refurbishment process. A machine that has been properly disassembled, cleaned with medical-grade solutions, had all patient-contact parts replaced, and been certified by a licensed clinical professional is a fundamentally different product from a used machine sold on Craigslist.

  • Unsafe: Machine sold by an individual with no clinical background, no data wipe, no part replacement, and no warranty
  • Safe: Machine refurbished by a licensed DME supplier, certified by a Licensed Respiratory Therapist, with new patient-contact parts, documented data wipe, and written warranty

The 3 Biggest Safety Concerns — Addressed

1. Contamination Risk

At MyRespCo, every refurbished unit receives new tubing, new filters, new water chamber, and new mask components. The internal airway path is cleaned with medical-grade disinfectant. No prior patient's air path components are ever reused.

2. Mechanical Integrity

Every MyRespCo unit undergoes motor output testing and pressure calibration against factory specifications, followed by a 48-hour burn-in test. This is signed off by a Licensed Respiratory Therapist (RRT).

3. Data Privacy

Before any refurbished machine ships, all prior patient data is fully wiped. Your therapy starts fresh with no prior patient's data on the device.

Red Flags When Buying Refurbished CPAP

  • Seller is an individual, not a licensed DME business
  • No warranty offered or warranty is vague
  • No mention of data wipe or patient-contact part replacement
  • No clinical professional involved in the refurbishment
  • No return policy

Bottom Line

A refurbished CPAP machine from a licensed, RRT-certified supplier is clinically safe and delivers identical therapeutic outcomes to a new machine — at 40–60% lower cost. The key is knowing who refurbished it and how.
