Design, Weight and Appearance
The ResMed AirSense 11 and AirSense 10 devices share a sleek, modern aesthetic, but their form factors differ significantly. The AirSense 11 introduces a more streamlined, low-profile design that looks less like a medical device and more like a modern bedside clock.
More importantly, the AirSense 11 is substantially lighter, weighing just 1130 grams compared to the AirSense 10’s 1428 grams. This 22% reduction in weight makes the Air11 a far superior choice for frequent travelers. Furthermore, the AirSense 11 features a large, full-color touch screen, completely replacing the AirSense 10’s traditional button-and-dial navigation, making setting adjustments effortless.
Performance and Clinical Features
Both devices are engineered to deliver industry-leading continuous positive airway pressure, keeping your airway open while you sleep. However, the AirSense 11 brings several major clinical upgrades to the table.
One of the most critical differences is their supplemental oxygen capacity. While the AirSense 10 can handle up to 4L/min of supplemental oxygen, the AirSense 11 is built to support flows of up to 15L/min. This makes the AirSense 11 the definitive choice for patients with overlapping respiratory conditions (such as COPD) who require higher oxygen concentrations during their CPAP therapy.
Additionally, the AirSense 11 includes an advanced AutoRamp™ sleep onset detection technology that detects sleep onset, and an improved HumidAir™ heated humidifier system.

User Interfaces and Smart Connectivity
While the AirSense 10 prioritized pure machine strength, the AirSense 11 perfectly bridges the gap between medical efficacy and modern digital convenience. Both machines connect to the myAir app, but the AirSense 11 takes it a step further by adding Bluetooth® connectivity for seamless smartphone pairing.
The AirSense 11 introduces an exclusive suite of digital tools designed to ensure therapy compliance. The Test Drive feature allows new users to comfortably get used to the airflow before actually going to sleep. The Personal Therapy Assistant provides interactive voice and video guidance, while the Care Check-In feature asks you tailored questions about your comfort and therapy progress. Best of all, thanks to Over-The-Air (OTA) updates, the AirSense 11 software will continuously improve and update itself, just like your smartphone.
Sleep Therapy Algorithms
A huge advantage of the AirSense 11 is that it includes the "AutoSet for Her" algorithm right out of the box. In the previous generation, female patients had to purchase a specifically branded AirSense 10 "For Her" machine to access this gentler pressure response. Now, patients can switch between the standard AutoSet and AutoSet for Her algorithms directly from the Air11's menu.
Ease of Use & Noise Level
Both machines operate at an incredibly quiet level of around 27 decibels. However, due to the refined motor design in the AirSense 11, many users report that it sounds subjectively smoother and less intrusive during inhalation and exhalation.
The transition to a touch screen on the AirSense 11 completely eliminates the learning curve associated with the push-dial interface of the AirSense 10, making it highly intuitive even for elderly users or those who are not tech-savvy.
Price and Release Date
The ResMed AirSense 10 CPAP was originally released in 2014 and remains an absolute workhorse in the industry. The AirSense 11 made its debut in late 2021, incorporating a full generation of technological advancements.
Naturally, as the newer flagship device, the AirSense 11 tends to be slightly more expensive. However, considering the built-in "For Her" algorithm, Bluetooth, OTA updates, lighter weight, and touch screen, the extra cost is highly justified for anyone looking for future-proofed technology.
Verdict
In conclusion, both the ResMed AirSense 11 and AirSense 10 CPAP devices are elite machines that deliver highly effective treatment for sleep apnea. The AirSense 10 remains an incredibly reliable, robust, and cost-effective option. However, the AirSense 11's superior connectivity, lighter footprint, significantly higher supplemental oxygen capacity, and built-in therapy assistant make it the more feature-rich option if budget allows.
Should You Upgrade from AirSense 10 to AirSense 11?
If you already own the dependable AirSense 10, the most critical question is: is it actually worth upgrading to the AirSense 11? The decision generally comes down to three main factors: the age of your current device, your connectivity needs, and your specific therapy requirements.
1. The 5-Year Lifespan Rule
Like most medical electronics, CPAP machines have a finite lifespan. ResMed officially designs and rates its CPAP units for a 5-year design life (which equates to roughly 15,000 to 20,000 hours of run-time). If your AirSense 10 is approaching or has already passed the 5-year mark, the motor inside may be losing its efficiency. Over time, a worn motor can struggle to deliver consistent therapeutic pressure and may run noticeably louder. In this case, upgrading is a proactive way to prevent unexpected device failure.
2. The Cellular Network & "Card-to-Cloud" Issue
Connectivity is a major point of divergence. Many older AirSense 10 units rely on 3G cellular modems to automatically transmit sleep data to the cloud. As telecommunication networks phase out 3G networks globally, these older units lose their wireless capabilities.
To bypass this, newer AirSense 10 units (often sold as Card-to-Cloud or "C2C" versions) do not feature built-in modems at all, meaning you must manually move an SD card to your computer to share data with your doctor. The AirSense 11 completely eliminates this hassle by utilizing modern, future-proof built-in cellular technology and Bluetooth® to sync automatically every single night.
3. Over-The-Air (OTA) Updates & The AutoSet Algorithm
The AirSense 11 is built on a highly modern digital architecture that supports Over-The-Air (OTA) software updates. This means that as ResMed refines its therapy algorithms (such as the updated AutoSet response) or releases new comfort features, your machine will automatically update itself over the air without requiring manual intervention. The AirSense 10, being a legacy device from 2014, is hardware-locked and cannot receive remote software improvements.
The Final Verdict: To Upgrade or to Wait?
You should upgrade to the AirSense 11 if:
- Your current AirSense 10 is more than 5 years old or showing signs of motor wear.
- You travel frequently and want a device that is 22% lighter (1130g vs 1428g) with a more compact bedside footprint.
- You want the ease of a modern, responsive touchscreen and interactive software like the Personal Therapy Assistant to help you stay compliant.
You can confidently stick with your AirSense 10 if:
- Your current machine is relatively new (under 3 years old) and still delivers quiet, reliable therapy.
- You are fully comfortable with the classic physical dial-and-button navigation.
- You do not mind manually transferring your sleep data via an SD card or do not require cloud monitoring.
Frequently Asked Questions (FAQ)
Is AirSense 11 quieter than AirSense 10?
Technically, both devices are officially rated at the exact same noise level (around 27 dBA).
