Best CPAP Machines 2026: Buyer's Guide

Choosing the Right CPAP Machine

You will use this machine every night for years, so the difference between "I tolerate my therapy" and "I actually sleep well" is worth a few minutes of reading. In 2026 there are strong options at every price point.

This guide covers the machines worth considering, what separates them, and the practical details that matter when you're spending your own money.

CPAP vs. APAP vs. BiPAP: A Quick Primer

Before diving into specific machines, it helps to understand the three main types of positive airway pressure therapy.

CPAP (Continuous Positive Airway Pressure) delivers a single, fixed pressure all night. Your doctor prescribes a specific number (say, 10 cmH2O), and the machine holds that pressure whether you need it or not. Simple, reliable, and often the least expensive option.

APAP (Auto-Adjusting Positive Airway Pressure) monitors your breathing and adjusts pressure in real time within a prescribed range (for example, 6 – 16 cmH2O). It increases pressure when it detects events and backs off when your airway is stable. Most modern machines sold as "CPAP" are actually APAP-capable. This is what the majority of new patients use today.

BiPAP (Bilevel Positive Airway Pressure) delivers two different pressures: a higher pressure when you inhale and a lower pressure when you exhale. Prescribed for patients who need high pressures but find constant pressure uncomfortable, or for those with central sleep apnea or complex breathing patterns. BiPAP machines are significantly more expensive and require a specific prescription. For a detailed comparison of how these two therapies differ, see our guide on BiPAP vs CPAP.

Most people reading this guide will be looking at APAP machines. Every machine below supports auto-adjusting mode.

The Machines

1. ResMed AirSense 11 AutoSet

The default recommendation, and the one this site sees most.

The ResMed AirSense 11 AutoSet is the machine most new patients are pointed at, and it is the most common machine among CPAP Clarity users by a wide margin: our CPAP data statistics count it outnumbering the AirSense 10 by close to 3 to 1 among imports. Its AutoSet algorithm responds to flow limitation before an event arrives rather than waiting for one, and it moves pressure in small steps, which is why it has the reputation it does for comfort.

Key features:

• AutoSet algorithm with expiratory pressure relief (EPR) up to 3 cmH2O
• Built-in Bluetooth and cellular connectivity for myAir app
• Integrated heated humidifier with climate control
• SD card with comprehensive therapy data (EDF format)
• Quiet operation: ResMed publishes 27 dBA with the humidifier tub, 25 dBA without
• Touchscreen display

What stands out: The AirSense 11 records some of the most detailed therapy data available on a home CPAP machine, and it is the best supported by third-party tools. Flow, pressure, and scored events are all written to the SD card. If you care about understanding your therapy (and if you're reading a CPAP data analysis blog, you probably do), this is the machine to have. For a detailed breakdown of how the AirSense 11 compares to its predecessor, see our AirSense 11 vs AirSense 10 comparison, and once you own one, how to get more from your AirSense 11 data.

Compatibility with CPAP Clarity: Full support. The AirSense 11 is the primary machine CPAP Clarity is built for. All signals, events, and summary data are parsed and displayed. Import your AS11 data now →

Pricing tier: Premium. A CPAP machine is a prescription device, so you buy it through a DME supplier or an online CPAP retailer that handles the prescription at checkout.

2. ResMed AirSense 10 AutoSet

Still excellent, and available at a lower price.

The ResMed AirSense 10 AutoSet is the predecessor to the AirSense 11 and remains a strong choice. ResMed still sells it new, and refurbished units are widely available at significant discounts.

Key features:

• Same proven AutoSet algorithm as the AS11
• Integrated heated humidifier with optional ClimateLineAir heated hose
• SD card with detailed therapy data
• Cellular modem (no Bluetooth)
• Dial-based navigation instead of touchscreen

What stands out: The therapy quality is essentially identical to the AirSense 11. The data it records is just as detailed, using a slightly different file naming convention but the same EDF format. If you can find one at a good price, it's a smart buy.

Compatibility with CPAP Clarity: Full support. All AirSense 10 data is fully parsed and analyzed. Try it with your AS10 data →

Pricing tier: Value.

3. Philips Respironics DreamStation 2

A strong alternative with a troubled history.

The Philips DreamStation 2 launched as Philips' answer to the AirSense 11 after the massive recall of the original DreamStation over foam degradation concerns. The DreamStation 2 uses a completely redesigned airpath with no PE-PUR foam. Availability is the catch for US readers. Under the consent decree Philips Respironics agreed to with the US government, it has not resumed selling new CPAP or BiPAP machines in the United States, so this is generally not a machine a US buyer can order new right now. Philips does continue to service devices already with healthcare providers and patients.

Key features:

• Auto-adjusting algorithm with A-Flex comfort feature
• Compact, modern design with color touchscreen
• Built-in Bluetooth for the Philips DreamMapper app
• Integrated humidifier
• Quiet operation: Philips publishes 27 dBA

What stands out: The DreamStation 2 is a well-built machine with a comfortable therapy algorithm. Philips has worked hard to rebuild trust after the recall. The A-Flex comfort feature is comparable to ResMed's EPR, reducing pressure during exhalation for a more natural breathing feel.

The caveat: The FDA is warning patients and health care providers to carefully monitor DreamStation 2 machines for signs of overheating. That issue is separate from the foam problem in the older DreamStation, and the FDA has not told people who are not experiencing it to stop using their machines, but it is worth knowing about and worth raising with your provider. Some users and clinicians also remain cautious about Philips after the recall. This is understandable. If you're considering a DreamStation 2, know that its design is fundamentally different from the recalled model. Discuss it with your prescribing physician.

Compatibility with CPAP Clarity: Full support. CPAP Clarity reads both the DreamStation 2 (decrypting its encrypted SD card) and the original DreamStation, showing the full nightly detail DreamMapper hides; see the DreamStation data guide. It also supports ResMed AirSense 10/11, AirCurve 10, the AirCurve 11 ASV, the BMC E-20A and G3 A20 (both on the BMC page), the React Health Luna G3, the Löwenstein Prisma Smart (EU-first APAP/CPAP), and the Yuwell YH-450.

Pricing tier: Premium.

4. React Health Luna G3

The budget-friendly option worth considering.

The React Health Luna G3 costs less than the ResMed and Philips machines without giving up the things that matter for therapy. It is FDA-cleared, it uses a capable auto-adjusting algorithm, and it writes full detail to an SD card. React Health took over the Luna line from 3B Medical, and the G3 replaced the older Luna II.

Key features:

• Auto-adjusting mode with Reslex exhalation relief
• Integrated heated humidifier and integrated heated tubing
• Optional cellular module and Wi-Fi for compliance reporting; React Health's manual and brochure list no Bluetooth
• SD card data logging
• Color screen, and a sound level of 28 dBA plus or minus 2, from React Health's user manual at 10 hPa. Its sales brochure claims under 26 dBA at the same pressure; we use the manual, because that is the document carrying the measurement standard

What stands out: The Luna G3's main advantage is price. For patients paying out of pocket (or with a high-deductible plan), the savings are real. The therapy algorithm is event-reactive: it raises pressure after it detects an event, where ResMed's AutoSet also responds to flow limitation before an event arrives.

Compatibility with CPAP Clarity: Full support. CPAP Clarity reads the Luna G3 card directly in the browser across three firmware families, with event counts cross-checked against OSCAR. Three channels you may be used to from a ResMed do not show up here, for three different reasons, and the Luna G3 review walks through each: respiratory rate appears only on the newer firmware, tidal volume and minute ventilation are a gap on our side rather than the card's, and nothing has confirmed which event codes are flow-limitation flags. The older Luna II is a different, proprietary format and is not supported.

Pricing tier: Value.

5. Lowenstein Prisma Smart

The European contender with advanced algorithms.

The Lowenstein Prisma Smart is popular in Europe and gaining traction in North America. It features Lowenstein's proprietary softPAP technology, which provides a uniquely smooth pressure transition that some users find more comfortable than competing machines. If you use one, CPAP Clarity reads the Prisma Smart's SD card data directly in your browser.

Key features:

• softPAP auto-adjusting algorithm
• Integrated humidifier
• SD card data recording
• Color display
• Optional integrated pulse oximetry module

What stands out: The Prisma Smart's softPAP algorithm takes a different approach to pressure adjustment. Instead of step-wise changes, it uses gradual, continuous adjustments that many users describe as more comfortable. The optional built-in oximetry module is a nice touch for patients who want SpO2 tracking without a separate device.

Compatibility with CPAP Clarity: Full support. CPAP Clarity reads the Prisma Smart's sessions, apnea and hypopnea events, settings, and pressure and leak waveforms, cross-checked against OSCAR across 29 rows with zero out of tolerance; see the Prisma Smart review.

Pricing tier: Mid.

6. ResMed AirMini

For travel, not as a primary machine.

The ResMed AirMini deserves a mention because many CPAP users end up buying a travel machine alongside their primary device. At roughly the size of a water bottle, it is one of the smallest CPAP machines you can buy.

Key features:

• Same AutoSet algorithm as the AirSense line
• Weighs only 300g (10.6 oz)
• Bluetooth connectivity
• HumidX waterless humidification
• FAA-compliant for in-flight use

What stands out: If you travel frequently, the AirMini solves the problem of lugging a full-size machine through airports. The therapy quality is excellent for its size. It does not have an SD card slot, so detailed data analysis is limited to what the AirMini app provides.

Compatibility with CPAP Clarity: Limited. The AirMini has no SD card, so there is no AHI, leak, or pressure detail to analyze. CPAP Clarity can import the AirMini's usage (your nightly hours) from the AirMini app's feedback export, but not the therapy waveforms.

Pricing tier: Premium (travel CPAPs carry a portability premium).

Noise and weight are each manufacturer's own published figure, and the basis differs by brand, so read the qualifier in the cell rather than the bare number. Pricing tiers are relative. Prescription CPAP machines are sold through CPAP suppliers that handle the prescription at checkout, and prices fluctuate.

Do You Need a Prescription?

Yes. In the United States, CPAP machines are Class II medical devices and require a prescription from a licensed provider. This applies to all the machines listed above.

How to get a prescription:

1. Sleep study. You'll need a polysomnography (in-lab) or home sleep test (HST) to diagnose sleep apnea. Many providers now offer home sleep tests that you can complete in your own bed.
2. Diagnosis. If you're diagnosed with obstructive sleep apnea, your provider will write a prescription specifying the type of device and pressure settings (or a pressure range for APAP).
3. Purchase. With a valid prescription, you can buy from a durable medical equipment (DME) provider, online retailers, or directly from some manufacturers.

Insurance considerations: Most health insurance plans cover CPAP machines with a confirmed diagnosis, though you may need to meet a deductible first. Some plans rent the machine for the first few months and require you to demonstrate compliance (typically 4+ hours per night on at least 70% of nights) before they'll purchase it outright.

Buying out of pocket: If you're paying cash, you'll often find better prices through online retailers than through your insurance's DME provider. You still need the prescription, but you have more control over which machine you get.

What Actually Matters When Choosing

After all the spec sheets and feature lists, here's what really makes a difference in daily use.

If you would rather answer a few questions than read six reviews, the machine finder narrows the list by pressure range, data access, travel needs and budget.

Comfort algorithm. This is the single biggest factor in whether you'll use your machine consistently. ResMed's AutoSet is the algorithm the others are usually measured against, but comfort is personal. If you can, try before you commit. Some DME providers allow 30-day trials.

Noise. All modern machines are quiet. Every full-size machine in the table above sits between 25 and 28 dBA on its manufacturer's own figures, and a difference of 3 to 4 dBA is about where a silent bedroom starts to notice, so noise is rarely the deciding factor between them.

Humidification. If you live in a dry climate or run air conditioning, a good heated humidifier prevents nasal dryness, congestion, and mouth breathing. Every full-size machine on this list includes one. Make sure to budget for a heated hose if your machine supports it. Heated hoses prevent condensation buildup (called "rainout") in the tubing.

Data access. If you want to understand your therapy and track your progress, the machine's data capabilities matter. ResMed writes an open EDF format that more third-party tools read than any other brand's, CPAP Clarity included; the BMC, Luna and Philips cards are proprietary formats that fewer tools have learned.

Mask compatibility. Most machines use universal connectors and work with most masks. ResMed machines pair especially well with ResMed masks for features like auto-mask-fit detection. Don't overlook the mask. A great machine with a bad mask is a bad experience. Budget for a quality CPAP mask.

Ongoing supply costs. Filters, water chambers, tubing, and mask cushions need periodic replacement. CPAP supplies are an ongoing recurring cost that adds up over the life of the machine; factor it into your budget.

The Recommendation

For most people buying a new CPAP machine in 2026, the ResMed AirSense 11 AutoSet is the one to beat. Its algorithm acts on flow limitation before an event rather than after, its SD card records flow, pressure and every scored event, and it has the widest range of masks and accessories built around it.

If budget is a primary concern, look for a refurbished AirSense 10 AutoSet. The therapy quality is identical, and the savings are meaningful compared to a new AirSense 11.

If you've had a good experience with Philips equipment in the past and your provider recommends it, the DreamStation 2 is a well-built machine, but check whether you can actually get one and read the caveats in its section above before you plan around it. For a detailed brand-level comparison, see our CPAP machine comparison covering all five major brands.

Whichever machine you choose, the most important thing is using it consistently. A "lesser" machine used every night will always beat a "better" machine that sits on the nightstand. Pick one that's comfortable enough that putting it on before bed is automatic, not a chore.
