If you’ve started shopping for a CPAP machine, you’ve probably noticed the same names coming up again and again. That’s not an accident. A handful of machines have become the default choice for most people starting PAP therapy, and knowing which ones — and why — can make your decision a lot easier.
The ResMed AirSense 11 AutoSet is the strongest candidate for the most popular CPAP machine on the market right now. But popularity doesn’t automatically mean it’s the right machine for you. In this guide, we’ll walk through the AirSense 11 and six other widely used machines, compare them on comfort, noise, humidification, portability, app features, and price, and help you figure out which one actually fits your situation.
One thing to keep in mind before we start: CPAP and APAP machines are prescription medical devices in the U.S. The right machine, and the right settings, should be worked out with a healthcare professional based on your diagnosis. This guide can help you understand your options — it isn’t a substitute for that conversation.

The Most Popular CPAP Machines at a Glance
| CPAP Machine | Best For | Type | Sound Level | Weight | Key Strength |
|---|---|---|---|---|---|
| ResMed AirSense 11 AutoSet | Best overall | APAP | ~26.9 dBA | ~0.79 kg | Comfort + smart features |
| Philips DreamStation 2 Auto CPAP | Philips users | APAP | ~26.5 dBA | ~1.02 kg | Compact design + Flex pressure relief |
| ResMed AirSense 10 AutoSet | Proven reliability | APAP | ~26.9 dBA | ~0.83 kg | Mature, dependable platform |
| React Health Luna G3 | Value seekers | APAP | ~27 dBA | ~1.13 kg | Lower-cost option with heated tubing |
| ResMed AirMini | Travelers | Travel APAP | ~30 dBA | ~0.28 kg | Extremely compact |
| Fisher & Paykel SleepStyle Auto | Humidification comfort | APAP | ~26.4 dBA | ~1.5 kg | Comfort-focused design |
| ResMed AirCurve 10/11 | Certain bilevel users | BiPAP | ~27–30 dBA | ~0.79–1.02 kg | Two pressure levels |
A quick note before you scan this table: not every machine here is interchangeable. CPAP, APAP, and bilevel devices serve different therapy needs. In simple terms, a standard CPAP delivers one fixed pressure all night, an APAP automatically adjusts pressure as your breathing changes, and a bilevel machine uses one pressure for inhaling and a lower pressure for exhaling. Which one you need depends on your prescription, not on which is more popular.
What Is the Most Popular CPAP Machine?
ResMed AirSense 11 AutoSet — The Most Popular Choice
The AirSense 11 has become the default recommendation for new CPAP users, and it’s easy to see why once you look at what’s inside the box.
AutoSet pressure adjustment. Rather than locking you into one pressure all night, the AutoSet algorithm makes small adjustments based on your breathing patterns. In practice, that often means fewer awakenings caused by pressure that’s too high or too low for a given moment in your sleep cycle.
Built-in humidification and AutoRamp. The integrated humidifier helps reduce the dry mouth and nasal irritation that cause a lot of people to quit CPAP therapy early. AutoRamp starts at a lower, more comfortable pressure and gradually increases it once it detects you’ve fallen asleep, which can make it easier to drift off in the first place.
The myAir app and compliance tracking. This is a bigger part of the AirSense 11’s popularity than most buying guides mention. The machine uses a built-in cellular modem to send your nightly data to the myAir app, where you get a daily “sleep score” along with tips for improving mask fit and reducing leaks. For many sleepers, that kind of feedback loop is genuinely motivating.
There’s also a practical side to this. Most U.S. insurance plans require documented proof of usage — typically at least 4 hours a night on 70% of nights within a 30-day window — before they’ll continue covering the machine or related supplies. Because the AirSense 11 automatically uploads this data, it removes a step that used to require manually uploading an SD card. That convenience is one reason clinicians frequently steer new patients toward it.
Compact design and noise. At under 27 dBA, the AirSense 11 runs quietly enough that most bed partners barely notice it. Its footprint is also smaller than older ResMed models, which matters if your nightstand space is limited.
Cleaning and maintenance. One thing to keep in mind: the AirSense 11’s water tub has a slightly more compact design than the AirSense 10’s, and some users — particularly older adults or anyone with limited hand dexterity — find it a little harder to open, remove, and clean. If easy disassembly is a priority for you, this is worth testing in person before you buy.
Mask compatibility. The AirSense 11 uses a standard 22mm hose connector, which is the same connector used across almost all full-size CPAP and APAP machines. In practice, that means you can pair it with masks from Philips, Fisher & Paykel, or other brands without an adapter. This standard connector isn’t universal across every device on this list, though — more on that below.
Pros
- Strong pressure algorithm with detailed app feedback
- Quiet operation for both user and bed partner
- Automatic data upload simplifies insurance compliance
Cons
- Water tub is more fiddly to clean than older models
- Touchscreen can be less responsive with wet hands
- Costs more than basic APAP machines
Best for: Most first-time CPAP users who want a modern, feature-rich APAP with strong app support.

How Recalls Shifted the CPAP Market
It’s worth pausing here to explain part of why the AirSense 11 dominates the popularity conversation today, because it isn’t only about features.
In 2021, Philips Respironics issued a large-scale recall covering millions of DreamStation and other PAP devices due to concerns about degrading foam inside the machines. The recall triggered a long remediation process, supply shortages, and a wave of patients and clinics switching to ResMed devices almost overnight. That shift is a major reason ResMed machines — and the AirSense line in particular — now represent such a large share of new CPAP setups. A 2026 dataset of identified CPAP machines found the AirSense 11 AutoSet accounted for 54.6% of the sample, though that figure describes the machines identified in that particular dataset rather than confirmed overall market share.
For readers researching the DreamStation 2, this history matters. It’s a different device from the recalled first-generation DreamStation, built with a redesigned foam-free architecture, but the recall’s aftermath is still part of why some shoppers approach Philips machines cautiously. We’ll cover that in more detail in the DreamStation 2 section below.
7 Most Popular CPAP Machines
1. ResMed AirSense 11 AutoSet — Best Overall
Everything above applies here. As a quick recap: strong auto-adjusting pressure, built-in humidification, detailed app data, and a quiet, compact design make this the machine most new users are steered toward. The main trade-offs are price and a water tub that’s a bit more effort to clean.
Verdict: The best all-around choice for most people starting therapy today.
2. Philips DreamStation 2 Auto CPAP — Best AirSense 11 Alternative
The DreamStation 2 is the machine most often compared directly against the AirSense 11, and for good reason — it covers similar ground with auto-adjusting pressure, integrated humidification, and a color display.
Flex pressure relief. Philips’ Flex technology slightly reduces pressure right as you exhale, which some users find more comfortable than ResMed’s approach, especially if you’re sensitive to pressure changes.
Design and cleaning. The DreamStation 2 has a straightforward water chamber that’s generally easy to remove and refill, and its display is easy to read at a glance.
Addressing the recall directly. If you’re researching Philips machines, you’ve likely come across news of the 2021 Respironics recall involving sound-abatement foam in older DreamStation devices. The DreamStation 2 was designed with a different, foam-free architecture specifically to avoid that issue, and it was not part of the original recall. That said, it’s reasonable for shoppers to want extra reassurance here, and it’s worth reviewing current guidance from Philips and the FDA before purchasing, particularly if you’re considering a refurbished or older-generation Philips device.
Pros
- Comfortable Flex pressure relief
- Easy-to-clean water chamber
- Often available at a lower price than the AirSense 11
Cons
- Smaller ecosystem of accessories than ResMed
- Recall history means some shoppers approach Philips cautiously
- App (DreamMapper) offers less detailed feedback than myAir
Verdict: Best alternative for shoppers who prefer Philips’ comfort features or find it at a better price.

3. ResMed AirSense 10 AutoSet — Best Proven Option
Even with the AirSense 11 now the flagship, the AirSense 10 remains extremely popular — largely because it’s cheaper, exceptionally durable, and has a larger, easier-to-clean water chamber than its successor.
Why it’s stuck around. The AutoSet algorithm on the AirSense 10 is essentially the same proven technology used in the 11, just without the touchscreen and cellular modem. For sleepers who want reliable performance without paying for the latest interface, that’s a reasonable trade-off.
Availability of supplies. Because it’s been on the market longer, replacement filters, water chambers, and tubing for the AirSense 10 are widely available and often cheaper than AirSense 11 equivalents.
AirSense 10 vs. AirSense 11
| Feature | AirSense 10 | AirSense 11 |
|---|---|---|
| Control | Physical dial | Touchscreen |
| Data upload | SD card or optional modem | Built-in cellular modem |
| Water chamber | Larger, easier to open | More compact, slightly fiddlier |
| Price | Generally lower | Generally higher |
| Software updates | Limited | Over-the-air updates |
This is a genuinely useful comparison for anyone deciding whether the newer model is worth the extra cost. If you want automatic data upload and a touchscreen, the 11 is worth the upgrade. If you’d rather save money and don’t mind a physical dial, the 10 still holds up well.
Verdict: A dependable, budget-friendlier choice for sleepers who don’t need the newest interface.

4. React Health Luna G3 Auto CPAP — Best Value
The Luna G3 doesn’t carry the brand recognition of ResMed or Philips, but it’s earned a loyal following among budget-conscious shoppers.
What you get for less. The Luna G3 includes auto-adjusting pressure, integrated humidification, and — notably — an optional heated tubing add-on and a built-in cellular modem for compliance data, features that typically cost extra elsewhere.
Trade-offs. Build quality is solid but noticeably less refined than ResMed or Philips, and the companion app is less polished. Availability can also vary more by region and supplier.
Pros
- Lower upfront cost than the major brands
- Heated tubing option improves comfort in dry climates
- Built-in cellular modem for compliance tracking
Cons
- Less brand history and long-term track record
- App experience is more basic
- Accessories can be harder to find locally
Verdict: A strong value pick, not a claim to being equally “popular” as ResMed — it’s the machine to consider if your priority is cost.

5. ResMed AirMini — Most Popular Travel CPAP
The AirMini is in a category of its own. At roughly the size of a soda can, it’s the smallest full-featured APAP most people will ever see.
Size and convenience. Weighing under a pound, the AirMini fits easily into a backpack or laptop bag, which is a big part of why it’s become the default travel machine for frequent flyers and campers alike.
HumidX waterless humidification. Instead of a water chamber, the AirMini uses a small HumidX cartridge that absorbs moisture from your exhaled breath and recycles it. It works reasonably well for short trips, though many users find the humidification noticeably weaker than a full-size machine with a traditional water chamber.
Proprietary mask connections. This is an important nuance that’s easy to miss. Unlike full-size CPAP machines, which almost universally use a standard 22mm hose connector, the AirMini uses a proprietary connector system tied to specific ResMed mask cushions. That means you generally can’t just bring your existing full-size mask and hose — you’ll need an AirMini-compatible setup, which is worth budgeting for separately.
Power options. Battery packs are available for off-grid use, which makes the AirMini popular for camping trips as well as air travel.
Pros
- Extremely portable and TSA-friendly
- Battery power options for off-grid trips
- Same AutoSet algorithm as full-size ResMed machines
Cons
- Weaker humidification than full-size machines
- Requires proprietary, AirMini-specific mask connectors
- Noticeably louder than the AirSense 11
Verdict: The clear choice for travel, as long as you budget for its specific mask setup.

6. Fisher & Paykel SleepStyle Auto — Best for Comfort Features
The SleepStyle Auto is worth considering primarily for its humidification design, which uses a “no-spill” thermal control system that some users find more comfortable and easier to manage than standard chambers.
Comfort-focused engineering. F&P designed the SleepStyle around a simplified, intuitive interface with minimal setup steps, which appeals to users who find touchscreens unnecessary.
One thing to keep in mind: availability of the SleepStyle Auto through U.S. direct-to-consumer retailers can be inconsistent compared with ResMed and Philips machines, so stock and pricing may vary more than the other options on this list. If you can’t find it readily, the Breas Z2 Auto is a lower-cost travel-oriented alternative worth researching, and shoppers in the UK or Europe may also come across the Löwenstein Prisma series in similar searches.
We wouldn’t present the SleepStyle as more popular than the AirSense 11 — the evidence doesn’t support that — but for sleepers whose top priority is a comfortable, low-fuss humidification experience, it’s a legitimate contender.
Pros
- Comfort-oriented humidification design
- Simple, minimal-step interface
- Quiet operation
Cons
- Inconsistent U.S. retail availability
- Smaller accessory ecosystem
- Data platform is less feature-rich than myAir or DreamMapper
Verdict: Worth considering if comfort-focused humidification is your top priority and you can find it in stock.
7. ResMed AirCurve 10/11 — Best Bilevel Alternative
The AirCurve isn’t simply a CPAP machine with extra features bolted on — it’s a different category of therapy, and it’s included here because bilevel devices show up frequently in “popular CPAP” searches.
CPAP vs. bilevel. A standard CPAP or APAP delivers one pressure (or an automatically adjusted range within one type of pressure) throughout the breathing cycle. A bilevel machine, by contrast, delivers a higher pressure during inhalation and a separate, lower pressure during exhalation. According to the FDA, this distinction is what separates bilevel devices from conventional CPAP machines, and it’s designed for people who need that kind of pressure differentiation for comfort or therapeutic reasons.
Who may need it. Bilevel therapy is typically prescribed for people who need higher pressures than a standard CPAP can comfortably provide, or who have specific respiratory conditions beyond obstructive sleep apnea. It’s not something to select simply because it seems like a more advanced machine — the extra pressure control is only useful if your prescription calls for it.
Verdict: A strong option, but only for the specific group of patients whose clinician has prescribed bilevel therapy — not a general upgrade path from CPAP.
Most Popular Sleep Apnea Machine vs. CPAP Machine
If you searched for “most popular sleep apnea machine,” you may be using that term more broadly than “CPAP.” Here’s how the terminology breaks down:
- “Sleep apnea machine” is the broad, consumer-facing term people often use for any device that treats sleep apnea.
- CPAP (continuous positive airway pressure) is the most familiar and widely prescribed type.
- APAP (automatic positive airway pressure) is another form of PAP therapy that adjusts pressure automatically — most machines on this list, including the AirSense 11, fall into this category.
- BiPAP/BPAP uses two separate pressure levels, as covered above.
What Is the Best Sleep Apnea Machine for Most People?
For many adults prescribed PAP therapy for obstructive sleep apnea, the ResMed AirSense 11 AutoSet is one of the strongest mainstream choices — but the appropriate device depends on your diagnosis, prescription, required pressure range, and your clinician’s recommendation. Popularity is a useful starting point for research, not a substitute for a prescription.
Why Are These CPAP Machines So Popular?
Comfort
Pressure relief features, ramp settings, humidification, and heated tubing all affect how tolerable a machine feels night after night. In practice, comfort is often the single biggest factor in whether someone sticks with therapy long-term.
Quiet Operation
Published decibel numbers only tell part of the story. Two machines with similar dB ratings can feel very different depending on the pitch of the motor and how much noise the mask itself adds — a loud mask can make a quiet machine feel noisy, and vice versa.
Automatic Pressure Adjustment
In simple terms, an APAP watches your breathing throughout the night and nudges pressure up or down as needed, rather than holding one fixed setting. For many sleepers, that flexibility means fewer pressure-related awakenings compared with a fixed-pressure CPAP.
Sleep Data and Smartphone Apps
- myAir (ResMed): Detailed nightly sleep scores, leak tracking, and mask-fit coaching.
- DreamMapper (Philips): Usage tracking and basic coaching, though generally less detailed than myAir.
- Other platforms: Budget machines like the Luna G3 typically offer simpler, less granular data.
App quality has become a real purchase driver, not just a nice-to-have — partly because of the insurance compliance requirements mentioned earlier.
Cleaning and Maintenance
This is an underrated factor in long-term satisfaction. Water tub design varies significantly: some, like the AirSense 10’s, are large and simple to open; others, like the AirSense 11’s, are more compact and slightly harder to disassemble. If you’re considering an ozone or UV cleaning device, check compatibility first, since not every manufacturer supports every third-party cleaner.
Availability of Masks and Replacement Supplies
Almost all full-size CPAP and APAP machines — including every model on this list except the AirMini — use a standard 22mm hose connector. In practice, that means you can generally pair a Philips mask with a ResMed machine, or vice versa, without an adapter. The AirMini is the exception: its proprietary connector locks you into AirMini-specific mask cushions, which is worth factoring into the total cost of a travel setup.
How to Choose the Right Popular CPAP Machine
Best Popular CPAP for First-Time Users
AirSense 11 — the combination of automatic data upload, a detailed app, and forgiving AutoSet pressure makes the learning curve easier.
Best Popular CPAP for Side Sleepers
The machine itself matters less here than mask choice and hose management. A low-profile mask and a hose management arm can matter as much as which machine you buy.
Related: [Best CPAP Mask for Side Sleepers]
Best Popular CPAP for Mouth Breathers
Again, this is largely a mask decision rather than a machine decision — a full-face mask or a chin strap paired with a nasal mask is usually the more relevant fix.

Best Popular CPAP for Travel
AirMini — just remember to budget for its proprietary mask connector.
Best Popular CPAP for Quiet Operation
Look at actual machine noise together with mask noise, not just the published spec sheet.

Best Popular CPAP for Budget Shoppers
React Health Luna G3 — genuinely lower-cost without giving up auto-adjusting pressure or humidification.
CPAP vs. APAP vs. BiPAP: What’s the Difference?
| Type | How It Works | Best Known For |
|---|---|---|
| CPAP | Fixed pressure | Traditional PAP therapy |
| APAP | Automatically adjusts pressure | Flexibility throughout the night |
| BiPAP/BPAP | Different inhale/exhale pressures | Specific pressure or comfort needs |
The most popular machine on this list — the AirSense 11 — is an APAP, and that’s true of most of the machines people gravitate toward today. But “most popular” doesn’t mean “best for everyone.” Your prescription, not general popularity, should determine which category you need.
What Features Matter Most When Buying a CPAP Machine?
In roughly the order we’d weigh them:
- Correct therapy type — matching your prescription (CPAP, APAP, or bilevel)
- Appropriate pressure settings — set by your clinician, not guessed
- Comfort features — ramp, pressure relief, humidification
- Noise — both machine and mask
- Humidification quality — chamber size and heated tubing options
- Mask compatibility — standard 22mm connector vs. proprietary systems
- Data tracking — how much detail you want about your own sleep
- App and connectivity — automatic upload vs. manual
- Portability — relevant mainly if you travel often
- Cost of replacement supplies — filters, cushions, tubing, and chambers add up over time
How Much Does a Popular CPAP Machine Cost?
Pricing varies by retailer and region, and figures change often enough that we won’t quote a single static number here — check current pricing before you buy. In general terms:
- Entry-level/value machines (like the Luna G3) tend to sit at the lower end of the market.
- Mid-range machines (like the AirSense 10 or DreamStation 2) fall in the middle.
- Premium machines (like the AirSense 11) sit at the higher end, largely due to app and connectivity features.
- Travel CPAPs (like the AirMini) are priced closer to premium full-size machines despite their small size.
If you have insurance, your out-of-pocket cost may be significantly lower than the retail price — it’s worth checking your coverage before assuming you’ll pay full price.
Total Cost of Ownership
The machine itself is only part of the cost. Over time, you’ll also need to budget for:
- Mask cushions or pillows
- Tubing (standard or heated)
- Filters
- Water chamber replacements
- Mask headgear
These recurring costs are one more reason mask and supply availability — not just the machine price — belongs in your decision.
Do You Need a Prescription for a CPAP Machine?
Yes. In the United States, CPAP and APAP devices generally require a diagnosis (usually from a sleep study) and a prescription before you can purchase one from most retailers. This is different from accessories like replacement cushions, filters, or tubing, which typically don’t require a prescription.
This article is for general educational purposes and isn’t medical advice. Talk with your doctor or sleep specialist about which device and settings are right for you.
