ResMed AirSense 10 vs AirSense 11: Which CPAP Is Right for You?
ResMed AirSense 10 vs AirSense 11: Which CPAP Is Right for You?
ResMed's AirSense 10 has been the gold standard of CPAP therapy for nearly a decade. The AirSense 11 launched in 2021 as its successor. If you're buying a new CPAP machine right now — or deciding whether to upgrade — the obvious question is: which one should you get?
The honest answer is more nuanced than most comparison articles admit. The AirSense 11 is not simply "better" in every dimension. Depending on your priorities, clinical needs, and budget, either machine could be the right choice. As a licensed Registered Respiratory Therapist who works with both machines regularly, here's the complete side-by-side breakdown.

Interface: Buttons vs. Touchscreen
The most immediately obvious difference between the two machines is the interface. The AirSense 10 uses physical buttons and a rotating dial — tactile, reliable, easy to navigate in the dark without looking. The AirSense 11 uses a full color touchscreen that's more visually polished but requires looking at the screen to operate.
For most settings adjustments, this doesn't matter — you configure ramp, EPR, and humidity once during setup and rarely touch the interface afterward. Where it matters: if you need to start or stop therapy or check your data while half-asleep at 3 AM, the physical button on the AirSense 10 is easier to find by feel than the touchscreen on the AirSense 11.
This is genuinely a preference split. Patients who prioritize a modern, intuitive interface prefer the AirSense 11. Patients who value tactile controls and simplicity often prefer the AirSense 10.
AutoSet Algorithm: How Different Are They Really?
Both machines include ResMed's AutoSet algorithm, which automatically adjusts pressure within your prescribed range in response to detected airflow limitation, snoring, and apnea events. The AirSense 11 uses an updated version of this algorithm.
The clinical reality: for the vast majority of patients with straightforward obstructive sleep apnea, the difference in algorithm performance between the AirSense 10 and AirSense 11 is not clinically meaningful. Both machines achieve excellent AHI control in typical OSA presentations. The AirSense 10's AutoSet algorithm has a decade of real-world validation and performs exceptionally well.
Where the updated algorithm may matter: patients with complex breathing patterns, high flow limitation burden, or positional OSA that requires more dynamic pressure response. If your sleep physician or RT has identified nuanced therapy needs, the AirSense 11's updated algorithm is worth the upgrade consideration. For most patients starting CPAP for the first time, both algorithms deliver equivalent outcomes.
Climate Control Auto: The AirSense 11's Biggest Practical Advantage
This is where the AirSense 11 has a genuine, meaningful advantage over the AirSense 10 for patients who struggle with humidity management.
The AirSense 10 offers manual humidity adjustment (levels 1–8) and is compatible with the ClimateLineAir heated tube, which helps prevent rainout. But the humidity level itself is a static setting — it doesn't respond to changes in room temperature or breathing patterns during the night.
The AirSense 11, when paired with the ClimateLineAir 11 heated tube, enables Climate Control Auto mode. In this mode, the machine actively monitors conditions and dynamically adjusts both tube temperature and humidity output to maintain a target delivered air temperature of 27°C at the mask. The result is:
- Automatic rainout prevention regardless of room temperature fluctuations
- More consistent humidity delivery through the night as conditions change
- No manual seasonal adjustment needed — the machine compensates automatically
For patients who have struggled with rainout or seasonal humidity adjustment on the AirSense 10, Climate Control Auto is a genuinely compelling reason to upgrade. For patients who've had no humidity issues on the AirSense 10 with a heated tube, the practical difference is smaller. For the full humidity optimization picture, see our guide on best CPAP humidity settings for AirSense 10 and AirSense 11.
Connectivity: Cellular vs. Cellular + Bluetooth
Both machines transmit therapy data via cellular to ResMed's cloud platform, making your AHI, leak rate, and usage data available in the myAir app and to your care team. The AirSense 11 adds Bluetooth connectivity, which enables faster data sync when your phone is nearby and supports additional features in the myAir app.
For patients, the practical difference is modest — your nightly data uploads to myAir on both machines. The Bluetooth addition on the AirSense 11 primarily improves the responsiveness of the app experience and enables the Personal Therapy Assistant feature.
Personal Therapy Assistant: Helpful or Gimmick?
The AirSense 11 includes a Personal Therapy Assistant feature accessible through the myAir app. It provides guided setup assistance, troubleshooting prompts, and personalized tips based on your therapy data. For new CPAP users who don't have clinical support readily available, this can be genuinely useful — it's like having a basic coaching layer built into the device ecosystem.
For patients with access to a licensed respiratory therapist for clinical guidance, the Personal Therapy Assistant is supplementary at best. It's a nice-to-have, not a must-have. Our $49.99 RT Consultation provides a level of clinical depth and personalization that no automated coaching feature can replicate — but for patients who want some in-app guidance between clinical touchpoints, it adds value.
Noise Level: Essentially Identical
The AirSense 10 operates at 26.6 dB; the AirSense 11 at 27 dB. This 0.4 dB difference is imperceptible to human hearing. Both machines are whisper-quiet in normal operation. Noise is not a differentiating factor between these two models.
Size and Weight: Essentially Identical
Both machines weigh approximately 670–680g without the humidifier and are similar in physical footprint. Neither has a meaningful advantage for travel or bedside placement. For dedicated travel use, the ResMed AirMini is the appropriate choice for either machine owner.
Price: A Real Consideration
New AirSense 11 units cost approximately $200–$300 more than new AirSense 10 units. On refurbished devices, the gap is similar — refurbished AirSense 10 units typically run $300–$500 versus $450–$650 for refurbished AirSense 11 units.
For cash-pay patients, this price difference is meaningful. If you're choosing between a new AirSense 10 and a new AirSense 11 and Climate Control Auto isn't a priority for you, the AirSense 10 delivers equivalent therapeutic outcomes at lower cost. The AirSense 10 is not an outdated machine — it's a current, fully supported device with a decade of proven performance.
For patients whose primary concern is cost, a professionally refurbished AirSense 10 from a licensed DME is an excellent option. See our guide on whether refurbished CPAP machines are safe to buy for the full clinical breakdown.
Which Machine Should You Choose?
Choose the AirSense 10 if:
- You're budget-conscious and want maximum therapy value per dollar
- You prefer tactile physical controls over a touchscreen
- You've had no humidity or rainout issues historically
- You want a proven, widely-supported machine with a decade of clinical track record
- You're purchasing refurbished and the AirSense 10 is the more accessible option
Choose the AirSense 11 if:
- You've struggled with rainout or humidity management and want Climate Control Auto
- You prefer a modern touchscreen interface
- You want the most current algorithm and platform from ResMed
- You value the Personal Therapy Assistant for in-app coaching
- Budget is not a primary constraint
The Clinical Bottom Line
Both machines are excellent. The AirSense 10 is not obsolete — it's a mature, well-validated platform that delivers effective therapy for the vast majority of OSA patients. The AirSense 11 offers meaningful improvements in humidity management and user interface that justify the price premium for patients who value those features. The decision comes down to whether Climate Control Auto and a touchscreen are worth $200–$300 more to you specifically.
AirSense 10 vs AirSense 11: BiPAP Variants
Both machines also come in bilevel (BiPAP) variants for patients who require separate inspiratory and expiratory pressures:
- AirSense 10: AirCurve 10 series (VAuto, S, ST, ASV, CS PaceWave)
- AirSense 11: AirCurve 11 series (VAuto, S, ASV)
The same comparison logic applies to the bilevel variants — the AirCurve 10 remains clinically excellent; the AirCurve 11 adds Climate Control Auto and the updated interface. For more on whether BiPAP is appropriate for your situation, see our guide on types of PAP therapy devices.
Frequently Asked Questions
Is the AirSense 10 being discontinued?
As of the time of writing, ResMed continues to support and manufacture the AirSense 10. It remains a current product with active manufacturing, warranty support, and ongoing clinical use. It has not been discontinued. That said, as the AirSense 11 matures and eventually a next-generation device is released, the AirSense 10's lifecycle will eventually wind down — as all medical devices do. For current availability and purchasing options, check with your DME supplier.
Can I use AirSense 10 accessories on the AirSense 11?
Not all accessories are cross-compatible. The ClimateLineAir heated tube for the AirSense 10 is NOT compatible with the AirSense 11 — the AirSense 11 requires the ClimateLineAir 11. Masks and standard tubing (non-heated) are generally compatible across both platforms. Verify accessory compatibility before purchasing.
Does the AirSense 11 work with the myAir app?
Yes. Both the AirSense 10 and AirSense 11 connect to the myAir app. The AirSense 11 supports additional features in myAir, including the Personal Therapy Assistant and enhanced Bluetooth-based data sync. Both platforms provide nightly AHI, leak rate, usage hours, and therapy scoring.
Is the AirSense 11 worth the extra cost?
For patients who have struggled with humidity management or rainout on the AirSense 10, Climate Control Auto on the AirSense 11 with a ClimateLineAir 11 tube is worth the premium. For patients with no humidity issues and no strong preference for a touchscreen, the AirSense 10 delivers equivalent therapy at lower cost. Neither answer is universal — it depends on which features you'll actually use.
Which machine is better for travel?
Neither the AirSense 10 nor the AirSense 11 is designed as a travel machine — both are full-size bedside units. For frequent travelers, the ResMed AirMini is the appropriate companion device for either machine. Both the AirSense 10 and AirSense 11 are FAA-approved for in-cabin use in a pinch, but the AirMini is far more travel-practical at under one pound.
The Bottom Line
The AirSense 10 and AirSense 11 are both excellent CPAP machines. They deliver therapeutically equivalent outcomes for the majority of OSA patients. The AirSense 11's key advantages — Climate Control Auto humidity management and touchscreen interface — are meaningful for patients who value those specific features. Its key disadvantage is a higher price point.
If you're a new patient choosing your first CPAP, either machine serves you well. If you're upgrading specifically because of humidity or rainout issues on your current AirSense 10, the AirSense 11 with Climate Control Auto is the targeted upgrade. If you're upgrading for algorithm improvements alone, the clinical benefit may not justify the price difference for most patients.
