Setup Guide: Water Chamber, Tubing, Filters, and Power
Setting up your AirSense 11 machine for the first time is straightforward and takes only a few minutes. Following this step-by-step AirSense 11 setup guide will ensure your device is ready to provide effective therapy from your very first night.
Step 1: Unboxing and Initial Check
Start by unboxing your machine and checking that you have all the main components. The box should contain the AirSense 11 device itself, a power supply, air tubing, the water chamber, and a filter. Keep in mind that some users who purchase a starter package will also have a mask included in their AirSense 11 Bundles.
Step 2: Preparing and Installing the Water Chamber
Next, you'll need to prepare and insert the Airsense 11 water chamber. Simply press the latch on the side of the machine to remove the chamber. Fill it with distilled water up to the marked fill line, never overfilling. Using distilled water is crucial as it prevents mineral buildup and helps your humidifier last longer. Once filled, slide the water chamber back into the machine until it clicks into place.

Data Tracking with the myAir App and SD Card
Tracking your progress is an essential part of successful CPAP therapy. The AirSense 11 makes this easy by giving you two main ways to see your data: through the convenient AirSense 11 myAir app and the traditional AirSense 11 SD card method. Both provide valuable insights, but they serve different purposes.
myAir App Tracking
The myAir app connects to your machine wirelessly using built-in cellular and Bluetooth technology. This means your therapy data is automatically sent to your phone or tablet shortly after you finish a session. The app is great for staying engaged and checking your progress on the go. It gives you a daily score and shows you key metrics, including:
-
Usage hours: How long you used your machine.
-
Mask seal: A rating of how well your mask fits throughout the night.
-
Events per hour: The number of breathing events (apneas) you had.
-
Mask on/off: How many times have you taken your mask off?
For most people, the myAir app provides all the necessary information to self-monitor their therapy and track their progress over time. It can also share data with your doctor remotely, which helps them keep an eye on your progress without needing an in-person visit.
SD Card Tracking
While the myAir app is ideal for daily feedback, the machine's SD card still plays a crucial role. It stores a more detailed, raw record of your therapy data. This is particularly useful for clinicians who need to access comprehensive compliance reports and high-resolution data logs. Some doctors may ask you to remove the SD card and bring it to your appointments so they can upload the data to their own software for a deeper analysis. The SD card also serves as a reliable backup in case of Wi-Fi or cellular connectivity issues.
In short, the myAir app is for immediate, day-to-day feedback and user engagement, while the SD card is for detailed reporting and clinical use. The AirSense 11 provides both, giving you and your healthcare provider the right tools to monitor your therapy effectively.

Comfort Settings – Pressure Relief, Humidity, and Heated Tubing
Making your CPAP therapy as comfortable as possible is the key to sticking with it long-term. The AirSense 11 comfort settings give you several ways to fine-tune your experience, from how the air feels when you breathe to the temperature of the air coming through your tube.
Pressure Relief
The AirSense 11 features Expiratory Pressure Relief (EPR), a setting that makes it easier to breathe out against the machine's pressure. It works by slightly lowering the pressure each time you exhale, which creates a more natural breathing sensation. You can adjust this feature to three different levels or turn it off completely. Using EPR doesn't compromise the effectiveness of your therapy; it simply makes it feel much more comfortable and less restrictive, especially for new users getting used to the pressure.
Humidity Control
The integrated humidifier is designed to prevent common side effects like a dry nose or a sore throat. The AirSense 11 humidity control can be set on a scale from 1 (lowest) to 8 (highest) or put in an automatic mode. Adjusting this setting can help you find the perfect level of moisture for your needs:
-
Low to medium humidity (1–4): Good for warmer or more humid climates.
-
Medium to high humidity (5–8): Ideal for dry, cold environments or if you're experiencing congestion.
-
Auto mode: The machine automatically adjusts humidity based on the room's temperature and humidity.
Heated Tubing
For ultimate comfort, the machine works with the ClimateLineAir 11 heated tube. This accessory pairs directly with the machine to maintain a consistent air temperature from the device to your mask. It also prevents "rainout," which is when condensation builds up inside the tube and can cause a gurgling sound or water droplets on your face. The temperature can be adjusted to a level you find comfortable.
These three settings work together to provide a personalized and comfortable therapy experience. Adjusting your EPR for easier breathing, your humidity for ideal moisture, and the heated tube for consistent warmth can make a huge difference. Finding the right combination may take some time, so feel free to experiment with the settings to see what works best for you.
Common Issues and Troubleshooting (Leaks, Water Chamber, Dryness)
Even with the best equipment, you might run into a few small snags. Many people search for quick solutions when they notice their mask is leaking, their therapy feels too dry, or they have issues with the water chamber. The good news is that most AirSense 11 problems have simple, straightforward fixes. This AirSense 11 troubleshooting guide will walk you through the most common issues.
Why is my AirSense 11 mask leaking?
Mask leaks are a very common issue and can often be fixed with a simple adjustment. The main reasons for a leak are that your mask is either too loose or too tight, your cushion is worn out, or the mask itself isn't the right size for your face.
-
Adjust the fit: Gently adjust your headgear straps to create a seal, but don't overtighten them. An overly tight mask can cause as many leaks as one that is too loose.
-
Check the cushion: If your mask cushion is old, it might have lost its shape or become stiff, making it unable to create a proper seal. Consider replacing the cushion or the entire mask.
-
Confirm the size: Make sure you're using the correct mask size for your face. If you're constantly fighting leaks, a different size or even a different style of mask might be a better fit.
Why does my AirSense 11 water chamber leak or not work properly?
The most common cause of a leaking water chamber is overfilling. The machine is designed to work with a specific amount of water, and putting in too much can cause leaks. Another issue is condensation, which can lead to water in your tubing.
-
Don't overfill: Only fill the water chamber up to the marked fill line. This prevents spills and ensures the chamber works as intended.
-
Check placement: Make sure the water chamber is correctly inserted and locked into place in the machine. A slight misalignment can cause a leak.
-
Prevent condensation: If you find water in your tubing, it's often due to "rainout," where warm, humid air cools and turns back into water. Using the ClimateLineAir 11 heated tube is the best way to prevent this from happening.
Why is my AirSense 11 causing dryness in my mouth or nose?
Dryness is one of the most common complaints, especially when starting CPAP therapy. It's usually caused by a humidity setting that's too low, or if you're breathing through your mouth at night.
-
Adjust your humidity: Go into the machine's menu and increase the humidity level. Try a slightly higher setting each night until you find a level that feels comfortable.
-
Use a heated tube: The ClimateLineAir 11 heated tube works with the humidifier to maintain consistent warmth and moisture, which is much more effective at preventing dryness.
-
Consider a full-face mask: If you're a mouth breather, the air pressure from a nasal or nasal pillow mask can dry out your mouth. A full-face mask covers both your nose and mouth, preventing air from escaping and causing dryness.
Accessories and Replacement Parts for AirSense 11
Just like with any medical device, keeping your AirSense 11 in top shape requires regular maintenance and part replacement. Using the right AirSense 11 accessories and swapping out old components on a schedule not only ensures your therapy remains effective but also keeps it clean and comfortable.
Essential Replacement Parts
-
Filters: The disposable filter, located at the back of the machine, is crucial for preventing dust, pollen, and other allergens from entering your device and potentially your lungs. It should be replaced every 1–2 months, or more often if you live in a dusty environment.
-
Water Chamber: The HumidAir 11 water chamber should be replaced every 6 months. Over time, mineral buildup from water (even distilled water) or small cracks can affect its performance and cleanliness.
-
Tubing: Both standard tubing and the ClimateLineAir 11 heated tube should be replaced every 6–12 months. This prevents bacteria buildup and ensures there are no leaks or tears that could affect pressure.
-
Mask Cushions: This is the part of your mask that creates a seal on your face. Because it’s in direct contact with your skin, it should be replaced every 1–3 months to maintain a good seal and hygiene.
-
Headgear: The headgear, or mask straps, holds your mask in place. It can stretch out over time, leading to leaks. It's recommended to replace it every 6–12 months to ensure a secure and comfortable fit.
Accessories to Improve Comfort and Usability
-
ClimateLineAir 11 Heated Tube: This is the most popular accessory for the AirSense 11. It works in conjunction with the integrated humidifier to deliver consistent temperature and moisture, thereby preventing condensation and dryness.
-
HumidX and HumidX Plus Cartridges: While these are not compatible with the AirSense 11, they are an excellent waterless humidification option for ResMed's travel-sized AirMini machine. They provide a compact way to get moisture without needing a water chamber.
-
CPAP Cleaning Products: To keep your mask and tubing sanitary, consider using specialized cleaning wipes, sprays, or a CPAP cleaning machine.
-
Travel Cases and Power Options: A durable travel case is great for protecting your machine on the go. For situations where a power outlet isn't available, a portable CPAP battery can provide peace of mind.
