Whether you're looking to buy your first CPAP, considering an upgrade from the AirSense 10 to the 11, or simply trying to understand the differences between these two ResMed CPAP machines, this guide covers everything you need to know.
AirSense 10 vs AirSense 11: 30-second summary
AirSense 10 AutoSet
DiscontinuedReleased in 2014. Dial control + LCD screen. Hugely popular, loved for its simplicity and reliability. The "Toyota Camry" of CPAP machines: no surprises, just works. No longer manufactured.
AirSense 11 AutoSet
Current modelReleased in 2021. Touchscreen, Bluetooth, compact design, built-in AutoSet For Her mode, therapy coaching via myAir (Care Check-In, Personal Therapy Assistant, Test Drive). OTA updates. The model available today.
In terms of therapy quality, both use the same AutoSet algorithm from ResMed with the same pressure range (4–20 cm H₂O). The core therapy is virtually identical — it's the experience around it that differs.

The differences that actually matter
1. Dial vs touchscreen
This is the most noticeable daily difference. The AirSense 10 uses a rotary dial and LCD screen — simple, reliable, zero fuss. The AirSense 11 switches to a colour touchscreen with auto-adjusting brightness. If you're comfortable with a smartphone, you'll pick it up quickly. If you prefer physical controls, the dial on the 10 has its fans.
2. Coaching: where the 11 really stands out
Both machines send your therapy data to the myAir app (sleep score, leak data, events). But the AirSense 11 goes further with a full onboarding ecosystem:
- Personal Therapy Assistant — setup videos, FAQ, guided troubleshooting
- Care Check-In — check-in questions during your first month to help optimise your adaptation
- Test Drive — a trial mode to familiarise yourself with the machine and test your mask seal before your first real night
If you're new to CPAP, this is a real advantage. If you're an experienced user, you may never need it.
3. AutoSet For Her: built-in vs separate model
The AutoSet For Her mode is designed for female-specific breathing patterns. On the AirSense 10, you had to buy a separate model. On the AirSense 11, it's built in as standard across all AutoSet models — one machine, all profiles.
4. Design, weight and travel
The AirSense 11 is lighter (1,130 g vs 1,247 g) and more compact. Its 65 W power supply (vs 90 W) is also an advantage if you travel with a portable battery. On the other hand, its hose connects directly at the rear — some users prefer to add a swivel elbow for a side-mounted setup like the 10.
5. Supplemental oxygen
A technical point, but important for some patients: the AirSense 11 supports supplemental oxygen flow rates of up to 15 L/min, compared to 4 L/min on the 10.
6. Software updates (OTA)
The AirSense 11 receives Over-the-Air updates: ResMed can improve algorithms and features remotely. Your machine can actually get better over time. The AirSense 10 doesn't have this capability — which some users actually prefer: no surprise changes to the menus.
7. Noise: virtually identical
Both come in at around 26–27 dBA, well below a whisper. The difference is imperceptible. The noise you hear most often comes from mask leaks, not the machine itself.
What users say
AirSense 10 fans appreciate: the more stable water tank (easier to fill without spilling), the included swivel elbow, the heated hose often bundled in the box, and the simplicity of a physical dial. Several users also find the pressure ramp feels slightly "smoother" on the 10.
AirSense 11 fans appreciate: the slimmer design for travel, the touchscreen, fast Bluetooth sync with myAir, the setup guide for beginners, and automatic software updates. The built-in AutoSet For Her mode is also frequently mentioned.
The most common feedback: the AirSense 11 water tank is a bit trickier to fill without spilling. Community tip: fill the tank while holding it slightly tilted with the openings facing up, then set it flat to check the water level before reinserting it.
Which model should you choose?
The AirSense 10 was right for you if:
- You wanted a "plug & sleep" machine, ultra simple
- You were looking for the best value for money
- You were comfortable with your CPAP routine
- You preferred a physical dial over a touchscreen
→ If your AirSense 10 is still working well, there's no need to switch. Replacement parts remain available.
The AirSense 11 is right for you if:
- You're starting CPAP therapy and want guided support
- You travel often (1.13 kg + 65 W power supply)
- You want Bluetooth and full tracking via myAir
- You want a machine that improves with software updates
- You're buying a new CPAP in 2025 → this is the current model

Accessory compatibility: watch out for the Air10 / Air11 trap
Many accessories are not interchangeable between the AirSense 10 and AirSense 11. Here's what works — and what doesn't:
| Accessory | Compatible between Air10 & Air11? |
|---|---|
| CPAP masks (all brands) | ✅ Yes |
| Standard hose (non-heated) | ✅ Yes |
| Swivel elbow | ✅ Yes — fits both models |
| Filters | ❌ No — AirSense 10 filters and AirSense 11 filters each have their own part number |
| HumidAir water chamber | ❌ No — model-specific shape |
| ClimateLineAir heated hose | ❌ No — Air10 vs Air11 specific version |
| Power supply | ❌ No — 90 W (Air10) vs 65 W (Air11) |
In short: if you're switching from an AirSense 10 to an 11, you can keep your masks, standard hose and swivel elbow. But you'll need to replace the filters, water chamber, heated hose and power supply.

Travel: which CPAP machine to take?
If travel is a major factor in your CPAP choice, the AirSense 11 has the edge: more compact, lighter, 65 W power supply (easier with a portable battery), and a higher max altitude (3,008 m vs 2,590 m). Both are FAA-approved for air travel.
That said, if you travel very frequently and want the most compact option possible, consider a dedicated travel CPAP (such as the ResMed AirMini) — significantly smaller but with fewer features.

FAQ — AirSense 10 vs AirSense 11
It's mainly more modern: touchscreen, Bluetooth, coaching tools and software updates. In terms of pure therapy quality, both are very similar — they use the same AutoSet algorithm with the same pressure range. The best choice depends on your profile and how much value you place on digital support.
The AirSense 10 has been discontinued by ResMed. You may still find it as remaining stock from some retailers, but quantities are very limited and won't be restocked. The AirSense 11 is now the current model. Replacement parts for the AirSense 10 (filters, water chambers, hoses) remain available for existing users.
Partially. Masks, standard hoses and the swivel elbow are compatible with both. However, filters (different part numbers), HumidAir water chambers, ClimateLineAir heated hoses and power supplies are model-specific and not interchangeable.
No. Each model uses a uniquely shaped water chamber. The AirSense 10 chamber doesn't fit the 11, and vice versa.
The rated noise levels are virtually identical (≈ 26–27 dBA). The difference is imperceptible in practice. Perceived noise depends mainly on the mask, leaks, hose type and the environment around your bedside table.
No. On the AirSense 10, you need a separate model (AirSense 10 AutoSet For Her). On the AirSense 11, For Her mode is built into all AutoSet models and can be activated in the settings.
The AirSense 11 (65 W vs 90 W). In normal use the difference is minimal, but it matters if you're using a backup battery or power converter while travelling.
No. CPAP masks are compatible with both machines. However, you will need to change the filters (different part numbers), water chamber, heated hose and power supply.
Not necessarily. If your therapy is going well, you can continue without any issues — the therapy quality is the same. Replacement parts remain available. Upgrading mainly makes sense if you want Bluetooth, a more compact machine for travel, or if your current device is starting to show signs of wear.
Daily maintenance is the same for both models: empty and dry the water chamber and hose each morning. Once a week, hand-wash the mask, hose and water chamber with warm water and mild soap, then rinse and air dry. ResMed also recommends soaking the water chamber once a week for 15 to 20 minutes in a mixture of water and white vinegar (9:1) to dissolve limescale deposits. Avoid ozone- or UV-based cleaners.
