Product code: AirMini starter kit without mask (3811092)


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 allows your patients to tailor their comfort settings and view their therapy progress easily. They can also allow you to follow up on 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 minimise vent flow and enable the delivery of efficient therapy performance.

The HumidX™ waterless humidification can be inserted between the mask and the tube, allowing it to capture the air’s warmth and humidity before it escapes through the tube’s built-in vent.

As simple to use as it is 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 a patient breathes in or out.

Optimised performance from device to mask

AirMini’s technologies have been developed exclusively alongside ResMed’s latest range of masks, the 20 series of full face and nasal masks, as well as the AirFit P10 for AirMini nasal pillows mask.

This means you can help your patients tailor their experience to suit a wide range of therapy, lifestyle or travel needs while providing the level of quality therapy you have come to 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.

Accessories for every lifestyle

A range of optional accessories allow your patients to enjoy even more flexibility.


HumidX system

Exclusive to AirMini, HumidX and HumidX Plus are small heat and moisture exchangers (HME) that are designed to provide comfortable and effective humidification.


AirMini mount system

The ResMed mount system allows the AirMini device to be secured to various points such as a bedframe, bedside table, wall or airplane seat pocket.


AirMini travel bag

Take your sleep therapy everywhere you go with the AirMini travel bag. Small and compact, it’ll fit the whole solution to keep everything together, so it’s always ready when you are.


The AirMini tube has unique proprietary connectors to connect to the AirMini machine and compatible masks, including ResMed 30 and 20 Series masks, and AirFit P10 for AirMini mask. This proprietary air tubing enables the use of new technologies for CPAP therapy, including the ActiveAir vent, HumidX waterless humidification and the miniaturised AirMini machine, 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 the small and simple mask connectors compatible with ResMed latest masks.

Typically, masks feature a vent, comprised of one or more fixed orifices, 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. The ActiveAir includes a pressure activated silicone membrane valve that responds to the CPAP pressure. As pressure increases in the mask, the ActiveAir reduces vent flow to a level that maintains CO2 washout from the system while reducing the overall flow output required at higher pressures of the AirMini device.

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

The optional HumidX technology is integrated in the AirMini tubing and allows exhaled air to pass through the HumidX before reaching the mask vent. This configuration captures the heat and moisture from the air and returns it to the patient upon inhalation. The operation of the HumidX mimics the natural humidification processes of the nose to boost moisture levels when using CPAP therapy. The ability to capture the patient’s exhaled moisture before exiting the mask vent is designed to provide an increased usability and breathing comfort.

The HumidX must be replaced 30 days after the packaging is opened. If the HumidX was not used every day during the 30-day period, it must still be replaced. The HumidX design life is based on the date of opening the packaging not the number of days used during therapy.

ResMed does not recommend using the HumidX beyond 30 days. Although, the HumidX has been tested beyond its design life, ResMed supports the safe use of 30 days. If the HumidX is used beyond 30 days this can cause deterioration in cleanliness, humidification performance and breathing comfort which can affect safe and efficacious use of AirMini. The HumidX and other components of the AirMini system are to be regularly maintained as per the user instructions.

AirMini has all the same therapy modes as the AirSense 10 AutoSet for Her including: 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.

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

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. This required a new range of masks to be designed to work specifically with AirMini and these innovative new technologies.

Before connecting the AirMini machine 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 machine is set up correctly and plugged into a power source. Refer to the machine user guide for additional information on setup. On the smart device, enable Bluetooth®. Refer to the smart device user guide for instructions on enabling Bluetooth®. 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. Check the box on the Welcome screen and then tap Continue. On the AirMini machine, press the Bluetooth® button when prompted by the AirMini app. When the light on the AirMini machine starts to flash blue, Bluetooth® is enabled on the machine and ready to connect. On the smart device, tap Connect. When the AirMini machine is discovered, the machines name, ResMedXXXXXX, will appear in the accessory selection list. Select the machine name from the list to connect. The first time you pair the AirMini machine with the smart device, you will need to perform the authentication procedure. 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 machine’s QR code within the camera’s viewing frame. Note: The QR code is located on the back of the AirMini machine. Alternatively, you can authenticate by entering the four-digit key located on the back of the machine. Tap Continue. When successfully connected, the Bluetooth® connection icon is displayed in the top right corner of the AirMini app. 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 machine at a time.
