Proven CPAP Therapy at the Best Price Point — RRT-Certified

The ResMed S9 AutoSet is the predecessor to the AirSense 10 — and for patients who need reliable, clinically effective auto-adjusting CPAP therapy at the lowest possible price, it remains an excellent choice. Professionally refurbished by a Licensed Respiratory Therapist (RRT) at MyRespCo. Ships with a 1-year mechanical warranty and all new patient-contact components.

Why Choose the S9 AutoSet?

  • AutoSet algorithm — adjusts pressure automatically, no manual titration needed
  • H5i Heated Humidifier — integrated, reduces dry mouth and rainout
  • SD card data recording — AHI, usage, leak, pressure all stored for compliance reporting
  • Whisper-quiet motor — under 30 dBa
  • EPR (Expiratory Pressure Relief) — makes exhaling more natural and comfortable
  • SmartStart — therapy starts when you breathe into the mask
  • RRT-certified refurbishment — 7-step clinical process, 1-year warranty

CDL Drivers — S9 and DOT Compliance

The S9 AutoSet records compliance data on SD card including AHI, usage hours per night, mask leak, and pressure delivered. MyRespCo can extract and format this data into a DOT Medical Examiner compliance report for $49.99. Learn more about CDL CPAP Compliance.

Frequently Asked Questions

Can the S9 be used for CDL/DOT compliance?

Yes. The S9 records all required compliance data on SD card. MyRespCo prepares DOT-formatted compliance reports from S9 data at the same $49.99 rate.

Does the S9 work with the myAir app?

No — the S9 predates ResMed's cellular connectivity. Therapy data is accessed via SD card only. The AirSense 10 is the right choice if myAir app integration is important to you.

Does this come with a warranty?

Yes — 1-year full mechanical warranty on every refurbished ResMed S9 from MyRespCo.

Do I need a prescription?

Yes. Our $49.99 RT Consultation can guide you through your options. Book here.
