The best CPAP machine overall is the ResMed AirSense 11 AutoSet ($799–$819) for its auto-adjusting comfort and built-in humidifier. For a tighter budget, the AirSense 10 AutoSet ($699–$719) or a certified refurbished AirSense 11 ($449) deliver the same core therapy for less. Frequent travelers do best with the AirMini AutoSet ($879), while those needing bilevel or complex-apnea therapy should look at the AirCurve BiPAP lineup ($1,209–$3,019). All CPAP and BiPAP machines require a valid prescription.
With dozens of models on the market, picking the right one comes down to matching the machine to your therapy needs and budget — not just picking the newest release. Below are our current top picks by category, all in stock and shipping today.

What is a CPAP machine?
A CPAP (Continuous Positive Airway Pressure) machine treats obstructive sleep apnea by delivering a steady stream of pressurized air through a mask, keeping the airway open during sleep. This prevents the pauses in breathing that define sleep apnea and reduces snoring, improving both sleep quality and long-term health.
Best overall: ResMed AirSense 11 AutoSet — $799–$819
The AirSense 11 AutoSet is our most popular machine, and for good reason. Its AutoSet algorithm continuously adjusts pressure to your breathing, the integrated HumidAir heated humidifier and ClimateLineAir tubing prevent dryness, and Expiratory Pressure Relief (EPR) makes exhaling more comfortable. The myAir app gives you nightly therapy scores and data your provider can use to fine-tune treatment. It's a strong fit for both new and experienced CPAP users. See how it compares to its predecessor in our AirSense 11 vs. AirSense 10 review.
Best budget: ResMed AirSense 10 AutoSet — $699–$719
The AirSense 10 AutoSet is the most affordable new machine we carry, and it doesn't cut corners on core therapy: AutoSet pressure adjustment, an integrated HumidAir humidifier, and EPR for comfortable exhalation. It's a proven, widely used machine that's easy to recommend for new CPAP users on a budget.
Best travel machine: ResMed AirMini AutoSet — $879
Weighing under a pound, the AirMini AutoSet is one of the smallest CPAP machines on the market without sacrificing AutoSet's auto-adjusting therapy. Its waterless HumidX humidification means no water chamber to pack, and it pairs with the AirMini app for on-the-go therapy tracking. FAA-approved for in-flight use. See our full travel CPAP options.
Best value BiPAP: ResMed AirCurve 10 VAuto — $1,209–$1,229
If your prescription calls for bilevel therapy but you don't need the AirCurve 11's newer feature set, the AirCurve 10 VAuto delivers the same core dual-pressure therapy at a lower price. It's also available certified refurbished starting at $779 for even more savings.
Best advanced bilevel: ResMed AirCurve 11 VAuto BiPAP — $1,249–$1,269
For the latest bilevel technology, the AirCurve 11 VAuto adds updated comfort algorithms and connectivity on top of the same higher-inhale, lower-exhale therapy as the AirCurve 10 VAuto above — worth the upgrade if you want the newest feature set.
Best for complex sleep apnea: ResMed AirCurve 11 ASV — $2,999–$3,019
The AirCurve 11 ASV is our most advanced machine, designed for central and complex sleep apnea that standard CPAP or BiPAP therapy doesn't fully address. It automatically adjusts both pressure support and backup breathing rate. This machine is typically prescribed after a sleep specialist has diagnosed a complex or central component to your sleep apnea.
Different types of CPAP machines
Which "best" machine is right for you depends on the type of therapy your prescription calls for:
Standard CPAP
Delivers one fixed pressure all night, set during your sleep study. Simple, reliable, and typically the most affordable option — ideal for straightforward obstructive sleep apnea without significant pressure fluctuation needs.
Auto CPAP (APAP)
Automatically raises and lowers pressure throughout the night based on your breathing in real time. The most popular category today, including the AirSense 11, AirSense 10, and AirMini above.
BiPAP (bilevel)
Delivers a higher inhale pressure and lower exhale pressure. Prescribed for users who find a single CPAP pressure hard to tolerate, or for central/complex sleep apnea (in ASV and ST variants). See our full BiPAP machine lineup.
Travel CPAP
Compact, lightweight machines built for portability without sacrificing auto-adjusting therapy — like the AirMini above.
How to choose the best CPAP machine for you
- Match your prescription: your sleep study and doctor determine whether you need standard CPAP, APAP, or BiPAP — this narrows the field immediately.
- Comfort features: a heated humidifier and EPR make a meaningful difference in night-to-night comfort.
- Portability: if you travel often, prioritize a dedicated travel machine over carrying your primary unit.
- Budget: certified refurbished machines deliver the same therapy at 25–40% less than new, backed by a warranty.
- Noise level and data tracking: most modern machines are quiet and app-connected — check the specific model's listing for details.
The bottom line
For most people, the ResMed AirSense 11 AutoSet is the best all-around CPAP machine on the market today. Budget-conscious shoppers should start with the AirSense 10 or a certified refurbished machine, while frequent travelers and those with complex sleep apnea have dedicated options built for their needs.
