AirSense 11 vs AirSense 10: Key Differences and Which Parts Still Fit
Quick answer: The ResMed AirSense 11 and AirSense 10 deliver the same core CPAP therapy. The AirSense 11 is lighter, uses a touchscreen instead of a dial, and connects to ResMed’s myAir app with extra coaching features. Your mask works with either machine. Filters, water chambers and heated tubing are model-specific, so if you upgrade from an AirSense 10 to an AirSense 11, plan to replace them.

What’s actually different?
Size and weight. The AirSense 11 is noticeably lighter and more compact. That matters if you take your home machine on trips rather than buying a separate travel unit.
Controls. The AirSense 11 replaces the AirSense 10’s dial and buttons with a touchscreen. Some users find it easier to read and navigate. Others who are used to the AirSense 10 prefer the physical dial. Both give access to the same core comfort settings, such as ramp and humidity.
App and data. This is the biggest practical difference. The AirSense 11 links to ResMed’s myAir app, which tracks nightly usage and mask seal and offers guided setup and comfort tips. Most AirSense 10 units available new today are the Card-to-Cloud version. These store therapy data on an SD card and don’t connect wirelessly to myAir.
Noise. The difference is under half a decibel, which you won’t notice in a bedroom.
Humidifier. Both have an integrated heated humidifier with roughly the same water capacity. The AirSense 11 tub has a wider base that’s easier to fill and handle.
Therapy. Both machines deliver CPAP and auto-adjusting (AutoSet) therapy in their respective models. Neither is “stronger” than the other. Your prescribed settings carry over.
Which parts still fit if you upgrade?
This is where most mistakes happen. Here’s what carries over from an AirSense 10 to an AirSense 11, and what doesn’t:
| Part | Works on both? | What to do |
|---|---|---|
| Mask (any standard mask, any brand) | ✅ Yes | Keep your current mask and keep reordering its cushions |
| Mask cushions, pillows, headgear | ✅ Yes | These belong to the mask, not the machine |
| Filters | ❌ No | The AirSense 11 uses its own filter. See why the AirSense 11 filter is different → |
| Water chamber / humidifier tub | ❌ No | The HumidAir 11 tub fits only the AirSense 11 (and AirCurve 11) |
| Heated tubing (ClimateLineAir) | ❌ No | The AirSense 11 heated tube is built for the 11 series only |
| Standard (non-heated) tubing | Check the listing | Buy tubing listed as compatible with your exact model |
| Power supply | ❌ No | The two machines use different power supplies; use the one made for your model |
Simple rule: anything that touches your face stays. Anything that plugs into the machine gets replaced.
Should you upgrade from an AirSense 10?
You probably don’t need to upgrade if:
- Your AirSense 10 is working well and you’re comfortable with it
- You don’t use, or want, app-based tracking
- You already have a stock of AirSense 10 filters, chambers and tubing
An AirSense 11 makes more sense if:
- Your current machine is ageing or out of warranty
- You want wireless tracking and coaching through the myAir app
- You’d like a lighter machine for occasional travel
- You’re buying your first machine, since parts for the current model will stay easiest to find
Either way, a new machine requires a valid prescription. If yours has lapsed and you already have a diagnosis, you can usually renew your prescription online →
Why do most buyers end up choosing between these two?
For US buyers in 2026, the choice of new home machines is narrower than it used to be. Philips is currently not selling new CPAP machines in the US under a 2024 consent decree, though its masks and parts remain available. That leaves ResMed’s AirSense line as the most widely recommended option, with React Health’s Luna series as the main alternative.
Frequently asked questions
Is the AirSense 10 discontinued?
ResMed’s current home model is the AirSense 11. New AirSense 10 units are still sold by some suppliers while stock lasts, mostly as the Card-to-Cloud version without wireless app connectivity. Parts for the AirSense 10 remain widely available.
Is the AirSense 11 quieter than the AirSense 10?
No meaningful difference. Both run at roughly 27 dB, which is quieter than a whisper.
Can I use my AirSense 10 mask on an AirSense 11?
Yes. Masks connect through a standard tubing connection, so your existing mask, cushions and headgear work with either machine.
Does the AirSense 10 water chamber fit the AirSense 11?
No. The AirSense 11 uses the HumidAir 11 tub, which isn’t interchangeable with the AirSense 10, AirCurve 10 or S9 chambers.
Can I use my AirSense 10 heated tube on an AirSense 11?
No. Heated tubing is model-specific. The AirSense 11 needs its own ClimateLineAir 11 heated tube.
Do I need a new prescription to switch to an AirSense 11?
You need a valid prescription for any new machine. Most prescriptions specify the therapy type and pressure settings rather than a model, so a current prescription usually covers either machine.
How often should I replace AirSense 11 parts?
Filters every few weeks, water chambers about every six months, and tubing about every three months, or sooner if you see wear. See how often to replace each part →
