ResMed AirSense 11 Review (All Models):
Which CPAP Is Right for You? | Updated 2025

ResMed’s attention to branding is clear throughout, with subtle circular patterns echoing the company’s logo across the unit and marketing materials. The device also combines multiple textures: grooved ends, inset circles, and a rubberized base that prevents slipping. Even the Start/Stop button has a soft, tactile finish that adds to the overall premium feel.

The HumidAir Water Tub is crafted from a frosted plastic with a silicone seal. While lightweight and easy to handle, it is thinner than some competitors’ designs and carries only a six-month warranty. Care is recommended to prevent cracks or leaks over time.

In terms of size, the AirSense 11 measures 3.7” (9.4 cm) tall, 10.2” (25.9 cm) wide, and 5.5” (14 cm) deep with the humidifier attached. While slightly wider than the AirSense 10, it’s still 24% smaller overall and 10% lighter, making it easier to pack for travel without sacrificing a full-featured design.

The unit also weighs just 2.56 lb (1.16 kg) with the humidifier, so it’s lightweight enough to carry in a travel bag while still feeling sturdy on your nightstand.

AirSense 11 Exterior Features

Most of the innovation in the ResMed AirSense 11 is found inside the device, but there are a few key exterior features worth noting. The unit is designed with simplicity in mind, featuring just one large button on top. Despite the power symbol, this button is actually used to start or stop therapy. To power the device on or off, simply plug it in or unplug it. If the button flashes with a white light, it signals a system error. In that case, refer to the manual or contact our team for support.

On the back of the device, you’ll find the hose outlet connector. Unlike the AirSense 10, where the hose connected at a right angle, the AirSense 11 hose attaches straight on. This means you’ll need a bit more clearance behind the machine, which can be important if you like to keep your CPAP close to the wall. If you’d like a more detailed look at how the two models compare, check out our AirSense 10 vs 11 comparison review. Right beside the outlet connector is the air filter inlet cover, which houses the disposable filter.

ResMed suggests replacing the filter every six months, but in practice, it’s best to change it more frequently: about once a month, or whenever you notice discoloration. If you live with pets or in a dusty environment, replacing it even more often can improve air quality and protect your machine. Filters are not that expensive, and changing them regularly only benefits your therapy.

On the side of the unit is the SD card cover, which stores your therapy data. This is where the AirSense 11 sets itself apart from other CPAP devices. The machine not only collects detailed data, but also processes it in ways that personalize your therapy, giving you (and your doctor) insights that make treatment more effective and easier to follow.

AirSense 11 Data & Connectivity Features

We live in a data-driven world where tracking health and progress has become second nature. Just look at the popularity of Fitbit or Apple Watch. ResMed has applied that same philosophy to the AirSense 11, making sleep apnea therapy easier to follow and more motivating with real-time feedback.

This device offers both Bluetooth and cellular connectivity, which unlocks several smart features:

• MyAir App: ResMed’s patient app and online portal sync wirelessly with your machine. Each morning, you’ll see an easy-to-read “scorecard” (0–100) that shows your usage hours, mask seal, events per hour, and more.
  
  

• Care Check-In: A built-in coaching feature that asks setup and progress questions during your first weeks and months of therapy. With your consent, these responses are shared with your provider through ResMed’s AirView platform, giving your care team a clearer picture of your progress.
  
  

• Remote Monitoring: At RespShop, our respiratory therapists, polysomnographic technologists, and nurses on staff can review your AirSense 11 data through AirView and even adjust certain clinical settings remotely if you need help. This level of support goes far beyond what most online CPAP providers offer.
  
  

• Automatic Software Updates: Thanks to its wireless connection, the AirSense 11 can receive ResMed software updates automatically. That means your machine always has the latest features without you having to do anything.
   

This connectivity is one of the reasons the AirSense 11 stands out: it transforms therapy from a stand-alone device into a connected tool that keeps you engaged and supported every step of the way.

ResMed AirSense 11 Touch Screen Navigation

One of the biggest design changes with the AirSense 11 is the removal of the navigation knob found on earlier models. Instead, all controls are handled through a full-color touchscreen.

The display is sharp, with bright and appealing colors. Touch responsiveness is solid, though scrolling happens in fixed increments rather than matching the speed of your swipe. Compared to smartphones, the screen feels a little less fluid; an area where ResMed could improve in future versions. A built-in light sensor automatically adjusts screen brightness to match the room’s lighting, which helps at night.

The interface itself is simple and intuitive. From the home screen, you’ll find two primary options: My Sleep View and My Options.

• My Sleep View shows a summary of your last therapy session when you stop therapy, giving you an at-a-glance look at how your night went, similar to the myAir app.
  
  

• My Options lets you adjust comfort settings and access useful features like Airplane Mode and the Mask Fit Test.
   

While the touchscreen takes a little adjustment if you’re used to the older knob design, it keeps the AirSense 11 looking sleek and modern while making navigation straightforward.

The My Options Menu on the AirSense 11

The My Options menu is where most of the customization happens on the AirSense 11. Here you can adjust therapy settings to make your CPAP experience more comfortable and tailored to your needs.

• Ramp Time & AutoRamp: Traditionally, ramp time lets you ease into therapy by gradually increasing air pressure over a set period, adjustable in 5-minute increments. With the AirSense 11, ResMed takes it further with AutoRamp. This feature detects when you actually fall asleep and only then ramps up to your prescribed pressure. Whether you drift off in 5 minutes or 50, you’ll enjoy a lower starting pressure for maximum comfort. First introduced on the AirSense 10 AutoSet, AutoRamp is now standard across all AirSense 11 models.
  
  

• Climate Control & Heated Tubing: Another standout feature is Climate Control, designed to reduce common CPAP side effects such as dry mouth or “rainout” (excess moisture in the tubing). By upgrading to the ClimateLineAir 11 heated tubing, you can let the machine automatically regulate temperature and humidity, or you can switch to manual mode if the Auto setting ever feels uncomfortable. Keep in mind the ClimateLineAir 11 is the only heated tube compatible with the AirSense 11. Even without it, you can still adjust the humidifier settings manually.
  
  

The My Options menu makes it easy to fine-tune comfort features, ensuring your therapy feels natural and effective from night one.

AirSense 11 AutoSet Features

When it comes to auto-adjusting CPAP therapy, ResMed is the market leader, thanks to its advanced AutoSet algorithm available on the AutoSet model. This technology constantly monitors your breathing throughout the night and adjusts pressure levels in real time for the most comfortable and effective therapy.

The AutoSet algorithm can detect and respond to several disordered breathing patterns:

• CSA (Central Sleep Apnea)
  

• CSR (Cheyne–Stokes Respiration)
  

• RERA (Respiratory Effort–Related Arousal)

Why does this matter? Because sleep apnea isn’t static. The pressure you need can vary night by night and even hour by hour. Maybe you’re especially tired, sleeping in a different position, fighting a cold, or recovering after a big weekend. Whatever the reason, your therapy needs fluctuate.

That’s where AutoSet shines. By analyzing apnea events, breathing patterns, and airflow, the device automatically delivers just the right amount of pressure at the right time. This adaptability is one of the biggest reasons many users choose (and we recommend) the AirSense 11 AutoSet.

Within AutoSet mode, you also get two response options:

• Soft Response: Provides gentler pressure changes for a smoother feel.
  

• Standard Response: Reaches the required pressure faster, but you may notice stronger adjustments.
   

For most users, leaving the machine in auto mode is the best way to maximize comfort and therapy success.

That’s why the AirSense 11 AutoSet is the most popular choice among CPAP users who want comfort and flexibility.

AirSense 11 AutoSet For Her Feature

With the release of the AirSense 11, ResMed simplified its product line by no longer producing separate “For Her” models. Instead, the For Her mode is now included as a setting within the AirSense 11 AutoSet menu. This makes it easier to access without needing a dedicated device.

The AutoSet for Her algorithm uses slightly different parameters to better respond to breathing patterns often seen in women with sleep apnea. It’s a more personalized approach that can improve comfort and therapy effectiveness.

Note: While the AirSense 11 Elite can also detect advanced breathing events, it remains a fixed-pressure CPAP. These data points are intended for your physician to fine-tune your therapy.

AirSense 11 Expiratory Pressure Relief (EPR)

Another comfort feature on the AirSense 11 is Expiratory Pressure Relief (EPR). EPR lowers the air pressure when you exhale, making breathing feel more natural and less effortful. You can choose from three levels of relief, so it’s worth experimenting to find the setting that feels best for you.

For many users, EPR helps ease the adjustment to CPAP therapy and makes nightly use more comfortable.

Together with features like AutoRamp and Climate Control, EPR helps make the AirSense 11 AutoSet one of the most comfortable and user-friendly CPAP machines available today.

Using the ResMed AirSense 11

Starting therapy on the AirSense 11 is simple: press the Start button and the unit quietly begins at just 27 decibels, about the sound of a soft whisper. The humidifier will automatically start warming the water once therapy begins.

If you prefer warm air right from the start, you can activate the Warmup option from the More menu. This preheats the humidifier and shows an icon on the screen. Don’t worry if you forget to turn it off; the system cools itself after 20 minutes.

During therapy, the screen displays a variety of information about your session. If you’d like to go over any of these details or learn more about your sleep therapy, our team is always here to help.

The AirSense 11 comes with a 2-year warranty, while the supplied tubing and humidifier have a 6-month warranty. For safe use and maintenance:

• Wait at least 10 minutes after stopping therapy to let the humidifier cool before emptying the water.

• Refill the humidifier daily with distilled water.
  

• Clean the humidifier tub weekly, along with your tubing and outlet connector.
  
  

To remove the outlet connector: slide out the humidifier, press the internal tab firmly, and pull the connector through the socket. Wash these parts in warm water with mild dish soap, rinse with clean water, and air-dry out of direct sunlight.

If you use the ClimateLineAir 11 heated tubing, be sure it is completely dry before reconnecting; it has an electrical contact point that should never be wet.

Final Thoughts

The ResMed AirSense 11 is a modern, patient-friendly CPAP that blends advanced therapy algorithms with smart connectivity and a sleek, compact design.
