Let your patients travel with therapy. In total size, AirMini is the smallest CPAP device ever brought to market**.


Connect your patients to success. The AirMini app makes it easy for your patients to tailor their comfort settings and view their therapy progress. They can also let you follow their progress by sending their detailed therapy data to AirView.


Support your patients with confidence. AirMini features the same established algorithms as ResMed’s AirSense 10 series of sleep therapy devices.

ActiveAir technology

ResMed designed the innovative ActiveAir venting technology to regulate vent flow and enable the delivery of efficient therapy performance.

HumidX waterless humidification* can be inserted between the patient and the mask vent. It captures the warmth and humidity of exhaled air before it escapes through the tube’s built-in vent.

Simple and innovative, HumidX requires no water or electric power. Instead, its unique Heat and Moisture Exchange (HME) technology works in synergy with the built-in vent to maintain heat and moisture levels as the patient breathes in and out.

Optimised performance from device to mask

AirMini’s technologies have been developed exclusively alongside ResMed’s latest mask ranges, notably the N20 and F20 series of masks, as well as the  P10 and N30 for AirMini.
This means you can help your patients to tailor their experience to suit a wide range of therapy, lifestyle or travel needs while providing the level of quality therapy you expect from ResMed.

Stay connected

The AirMini app allows you to manage your patient’s settings and stay up to date with their therapy progress through AirView.

With instructional materials and customisable comfort settings just a few clicks away, patient setup and ongoing support is easier than ever.


Why does the AirMini tube have different connectors?

The AirMini tube has unique proprietary connectors to connect to the AirMini device and compatible masks. These include the ResMed N20 and F20 series of masks, as well as the airfit P10 and N30 for AirMini. This proprietary air tubing enables the use of new technologies for CPAP therapy, including the ActiveAir vent, HumidX waterless humidification* and the miniaturised AirMini device, while maintaining ResMed’s high standards for effective therapy. The AirMini tube enables an easy transition from AirSense or other CPAP systems to AirMini systems via small and simple mask connectors that are compatible with ResMed’s latest masks.

How does the ActiveAir technology work?

Typically, masks feature a vent, comprised of one or more fixed openings, to eliminate expiratory gases before the next inspiration. This minimises CO2 rebreathing and allows a critically sufficient vent flow at the minimum PAP pressure, with higher flows resulting at higher pressures. Vent flows higher than this critical flow provide no additional benefit. ActiveAir includes a pressure-activated silicone membrane valve that responds to the CPAP pressure. As pressure increases in the mask, ActiveAir reduces vent flow to a level that maintains CO2 washout from the system while reducing the overall flow output required at the higher pressures of the AirMini device.

Why did you move the location of the vent?

Moving the location of the vent allowed us to place the HumidX component between the patient and the mask vent. This is the only way the passive humidifier (HumidX) can properly function, as heat and moisture need to be captured from the patient’s exhaled breath before they are expelled from the vent.

How does HumidX technology work?

Optional HumidX technology is integrated in the AirMini tubing so exhaled air can pass through the HumidX before it reaches the mask vent.* This configuration captures the heat and moisture from the air so it can be returned to the patient upon inhalation. The operation of the HumidX mimics the natural humidification processes of the nose to improve moisture levels during CPAP therapy. Capturing the patient’s exhaled moisture before it exits the mask vent means it can be used to increase usability and breathing comfort.

Why can’t the HumidX F20 fit into an AirFit F30 mask?

The HumidX for F20 clicks into the AirFit and AirTouch F20 frame. It does not fit the AirFit F30, which has a different frame structure.

How often does the HumidX need to be replaced?

The HumidX, HumidX Plus or HumidX F20 must be replaced 30 days after the packaging is opened. It must be replaced even if the HumidX was not used every day during the 30-day period. The design life of HumidX components is based on the time that has elapsed since the packaging was opened, not the number of days it is used during therapy.

What if the HumidX, HumidX Plus or HumidX for F20 is used for more than 30 days?

ResMed does not recommend using the HumidX if the packaging was opened more than 30 days ago. Although the HumidX has been tested beyond its design life, ResMed supports the safe use period of 30 days. If the HumidX is used more than 30 days after opening, deterioriation in cleanliness, humidification performance and breathing comfort can occur and this can affect the safe and efficacious use of AirMini. The HumidX and other components of the AirMini system must be regularly maintained as per the user instructions.

What therapy modes are built into the AirMini system?

AirMini has all the same therapy modes as the AirSense 10 AutoSet for Her, namely CPAP AutoSet (with the option of Response) and AutoSet For Her. Unlike the AirSense 10 AutoSet, every AirMini device has all three of these therapy modes included.

Why is there no user interface?

AirMini is designed to support simplicity and deliver a richer experience depending on your patient’s preference. To do this, we designed AirMini with one-button interaction for simplicity and an accompanying app that can be used to unlock a richer, more engaging therapy experience.

Why are only some masks compatible with AirMini?

The AirMini system uses ActiveAir and HumidX technologies to enable the AirMini to be the world’s smallest CPAP device** while maintaining ResMed’s high standards for effective therapy. These innovative new technologies meant we had to design a new range of masks specifically for use with AirMini.

How do I pair AirMini with a smart device?

Before connecting the AirMini device to a smart device, ensure that the latest version of the AirMini app is installed on the smart device. If not, download the AirMini app from the App Store™ or Google Play™. Ensure that the AirMini device is set up correctly and plugged into a power source. Refer to the device user guide for additional information on setup.
Enable Bluetooth® on the smart device, referring to the smart device’s user guide if necessary. The first time you open the AirMini app, you will be asked to consent to the use of cookies and to accept ResMed’s Terms and Conditions and Privacy Policy. Once you have done this, tap Continue.
On the AirMini device, press the Bluetooth® button when prompted by the AirMini app. When the light on the AirMini device starts to flash blue, Bluetooth® is enabled and the device is ready to connect.
Tap Connect on the smart device. When the app discovers the AirMini device, the name of the device, ResMedXXXXXX, will appear in the accessory selection list. Select the device name from the list to connect.
You will need to perform an authentication procedure the first time you pair your AirMini device with your smart device. When prompted by the AirMini app, begin the authentication process by tapping Scan code. You will be prompted by the AirMini app to allow the use of the smart device’s camera and to position the QR code on the back of the AirMini device within the camera’s viewing frame. Alternatively, you can authenticate by entering the four-digit key located on the back of the device. Tap Continue. The Bluetooth® connection icon is displayed in the top right corner of the AirMini app when the device is successfully connected. Notes: As long as the AirMini is plugged into a power source, it is turned on and in standby mode. If the AirMini is plugged into a power source, leaving Bluetooth® enabled on the smart device ensures that each time the smart device comes within the vicinity of the AirMini, connection will occur automatically. You should only pair a smart device with one device at a time.
