If you’ve been prescribed CPAP therapy and ended up comparing the ResMed AirSense 10 and AirSense 11, you’re not alone. Both machines dominate clinics across Canada, and the question of which one to choose comes up constantly. The answer isn’t as straightforward as “newer is better,” but it’s also not complicated once you understand what actually changed between the two.
This comparison covers the real differences, who each device suits best, and what to consider whether you’re starting CPAP therapy for the first time or replacing an older machine.
The Quick Answer
The AirSense 11 is the current generation machine from ResMed. It includes a guided setup assistant, a refined app experience, and cellular data connectivity on select models. However, the AirSense 10 is still widely used, still supported, and still delivers excellent therapy. If your clinic is offering you either machine, the decision often comes down to your technology preferences and configuration setup.
What Is a ResMed CPAP Machine?
ResMed is one of the most widely prescribed CPAP manufacturers in the world. Their AirSense line, specifically the AutoSet models, uses automatic pressure adjustment (APAP) to respond to your breathing patterns in real time. Rather than delivering a fixed pressure all night, the machine titrates up or down based on what it detects. Most people prescribed a ResMed CPAP device in Canada are set up on the AutoSet variant of either the 10 or 11.

What Actually Changed in the AirSense 11
Guided Setup
The AirSense 11 includes an on-device setup assistant that walks new users through the initial configuration step by step. For first time users especially, this reduces the chance of a misconfigured humidifier or incorrect mask selection at the start of therapy. The AirSense 10 requires more manual setup, which is straightforward but less forgiving if you’re doing it alone.
Updated myAir App Integration
Both devices connect to ResMed’s myAir app, which gives you nightly sleep scores, mask leak data, and AHI readings. The AirSense 11 adds a Care Check-In feature, which prompts you to log how you’re feeling and surfaces pattern based suggestions. For users who want to be more hands on with their therapy data, this is a genuine upgrade. For users who just want to sleep and not think about it, it makes little practical difference.
Modernized Touchscreen Interface
One of the most noticeable differences is usability. The AirSense 11 replaces the AirSense 10’s physical dial-and-button navigation with a touchscreen interface that feels more modern and smartphone-like. Some users love the cleaner design, while others actually prefer the tactile reliability of the AirSense 10’s physical controls.
AutoSet for Her Algorithm
The AirSense 11 offers a gender specific algorithm mode called AutoSet for Her, designed to respond to breathing patterns more common in women, including flow limitations that don’t always trigger standard AutoSet responses. The AirSense 10 does have a separate “for Her” machine, but the 11 integrates this as a selectable mode in one device.
What Stayed the Same
Both machines use integrated HumidAir humidifiers, which are the same basic chamber design. Both are compatible with the full range of CPAP masks. Noise levels are nearly identical at around 26 to 27 dBA, quiet enough that most partners don’t notice. Core therapy performance is also comparable; the updated algorithm in the 11 is a refinement, not a reinvention.
If you’re already on the AirSense 10 and sleeping well, therapy effectiveness is not meaningfully different for the average user.
ResMed Heated Hoses: What You Need for Both Machines
The AirSense 10 and AirSense 11 do not use the same hose models. The hose connections are not interchangeable between heated hose models, so it’s important to choose the correct option for your machine.
The AirSense 10 uses the ClimateLineAir heated hose, while the 11 uses the newer ClimateLineAir 11 heated hose. Although they serve the same purpose, the connection points differ, meaning an AirSense 10 heated hose will not fit an AirSense 11, and vice versa.
Which Machine Should You Choose?
Choose the AirSense 11 if:
- You’re a new CPAP user. The guided setup reduces first night errors and the app gives you more feedback during the adjustment period.
- You prefer modern tech. The touchscreen interface, updated app integration, and Bluetooth-assisted setup make the AirSense 11 feel like a current generation connected device.
- AutoSet for Her applies to you. Having both algorithms in one device is more flexible than the 10’s setup.
- You want long term support. Parts, software updates, and support will be available longer for the 11 than the 10.
The AirSense 10 still makes sense if:
- It’s what your clinic is prescribing. There are valid clinical and supply reasons a clinic might still fit patients on the 10. Trust the recommendation.
- You’re replacing a machine you already know well. If you’ve used the 10 for years without issues, familiarity has value.
- Connected features don’t matter to you. The AirSense 10 still delivers excellent therapy without the extras.
- Cost is a significant factor. The AirSense 10 is generally less expensive, and insurance coverage timelines vary. Confirm what your plan covers before deciding.
Insurance Coverage in Canada
Both the AirSense 10 and 11 are covered under most extended health plans in Canada, though coverage amounts and eligible replacement timelines vary by insurer. Avant Respiratory works directly with most major insurers and can confirm your specific coverage before you commit to a device. If you’re choosing between the two based partly on cost, get the insurance picture sorted first.
Frequently Asked Questions
Is the ResMed AirSense 11 worth the upgrade from the 10?
For existing AirSense 10 users with stable therapy, probably not. For new users or those switching clinics, the 11 is the better starting point.
Are AirSense 10 and 11 masks interchangeable?
Yes. Both machines are compatible with the full ResMed and other brand mask ranges. Your mask choice is independent of which generation device you use.
Can I use my AirSense 10 accessories on the AirSense 11?
Some, but not everything. Your CPA
