Written by Yash, RRT — Licensed Respiratory Therapist & Owner, MyRespCo
You've done the research. You know you snore loudly, you wake up tired no matter how long you sleep, and you've read enough to suspect sleep apnea. But when you look into getting a CPAP machine, you hit a wall: prescription required. This guide explains exactly what that means, what your options are, and the most efficient path to getting the therapy you need — written by a Licensed Respiratory Therapist who deals with this every day.
Why Does a CPAP Require a Prescription?
The FDA classifies CPAP machines as Class II medical devices. This classification requires a valid prescription from a licensed healthcare provider before a DME supplier can dispense one. The rationale is clinical: the wrong CPAP pressure setting can be ineffective or uncomfortable, and identifying the correct therapy pressure requires clinical assessment.
This does not mean you need an expensive in-lab sleep study or a specialist appointment. It means you need a clinical evaluation from someone qualified to assess your sleep and breathing history — and that includes a Licensed Respiratory Therapist.
What Are Your Options?
Option 1 — Home Sleep Test + Physician Prescription (Traditional Path)
The traditional route: see a physician, get referred for a sleep study, receive a diagnosis of obstructive sleep apnea (OSA), and receive a CPAP prescription. This is thorough but slow — often 4–8 weeks and potentially expensive if you have a high-deductible insurance plan.
- Pros: Full clinical workup, insurance may cover the machine
- Cons: Time-consuming, expensive out of pocket without good insurance, machine often rented not purchased
Option 2 — Telehealth Sleep Consultation
Several telehealth platforms now offer online sleep apnea consultations with physicians who can order a home sleep test and issue a CPAP prescription — often within 1–2 weeks and at significantly lower cost than an in-person specialist visit. If you need a prescription pathway, this is the most efficient modern option.
- Pros: Fast, affordable, done from home
- Cons: Still requires a physician prescription; some platforms charge per service
Option 3 — RT Consultation at MyRespCo ($49.99)
MyRespCo offers a $49.99 RT Consultation with our Licensed Respiratory Therapist. In this 30-minute session, we review your sleep history, symptoms, prior sleep study data (if you have it), and help you understand your therapy options, appropriate machine types, and pressure considerations.
This is clinical guidance from an RRT — the same credential that manages CPAP therapy in hospitals, ICUs, and sleep labs. It is not a prescription service, but it is the clearest, fastest, and most affordable first step toward understanding your options and getting set up correctly.
- Pros: $49.99, same-week availability, RRT-level clinical knowledge, no insurance required
- Limitation: Not a prescription service — for a prescription you need a physician or authorized prescriber

What Is AHI and How Do I Know If I Need CPAP?
AHI stands for Apnea-Hypopnea Index — the number of breathing disruptions per hour of sleep. It is the primary metric used to diagnose and classify obstructive sleep apnea:
- AHI 0–4: Normal — no OSA
- AHI 5–14: Mild OSA — CPAP often recommended
- AHI 15–29: Moderate OSA — CPAP strongly recommended
- AHI 30+: Severe OSA — CPAP treatment essential
A home sleep test measures your AHI overnight and generates a report your physician or RT can use to guide therapy decisions. Home sleep tests are available through telehealth platforms and some DME providers for under $200 — no overnight hospital stay required.
Can I Buy a CPAP Without Going Through Insurance?
Yes — and it often makes financial sense. Insurance coverage for CPAP requires compliance monitoring, paperwork, and typically locks you into rental arrangements for 13 months before the machine is considered purchased. Many patients find that buying a refurbished CPAP machine outright from a licensed DME supplier is faster and more cost-effective, especially if they have a high deductible or want machine ownership from day one.
MyRespCo's refurbished CPAP machines start significantly below new retail prices, include a 1-year warranty, and are certified by a Licensed Respiratory Therapist. You own it outright from day one.

What If I Already Have CPAP Data from a Prior Machine?
If you've been on CPAP therapy before and have prior therapy data, an RT Consultation is an excellent way to review that data, assess how well your therapy was working, and determine whether your current settings and equipment are still appropriate. Bring your SD card or AirView/myAir login to the session and we can review your data together.

Frequently Asked Questions
Can I legally buy a CPAP without a prescription?
A prescription is required by FDA regulation for CPAP machines sold by licensed DME suppliers in the United States. However, the path to getting a prescription has become significantly more accessible through telehealth and home sleep testing — often resolved in 1–2 weeks without an in-person specialist visit.
What is an RT Consultation and what does it include?
MyRespCo's $49.99 RT Consultation is a 30-minute session with our Licensed Respiratory Therapist. We review your sleep history, symptoms, prior therapy data (if available), discuss appropriate machine types and features, and guide you on next steps. This is clinical guidance, not a prescription service.
How much does a home sleep test cost?
Home sleep tests through telehealth platforms typically range from $99 to $299 without insurance. Many insurance plans cover them. The test is mailed to you, worn overnight at home, and returned — results are usually available within a few days.
Is a refurbished CPAP as effective as a new one?
Yes — when purchased from a licensed RRT-certified DME supplier. MyRespCo's refurbished CPAP machines go through a 7-step clinical refurbishment process and include a 1-year warranty. Clinical effectiveness is identical to a new machine at 40–60% lower cost.
Do I need a prescription to buy a CPAP mask or accessories?
No. CPAP masks, tubing, filters, and accessories do not require a prescription. Only the CPAP machine itself requires a prescription under FDA regulations.
