    Product Features

    The Luna II QX Auto CPAP Machine can make all pressure adjustments automatically, reducing the need to make extra trips to the doctor for something as simple as pressure adjustments. This can help reduce the need for sleep studies and extra copays!

    You'll also appreciate having instant access to therapy data on your mobile device using the handy mobile app! Just scan the QR code on the machine display and instantly transfer your therapy data to your phone for an easy read.

    Automatic Pressure Adjustments - Fewer Trips to the Doctor

    The Luna II QX can select the therapy pressure automatically based on measurements from your breathing. Unlike fixed-pressure machines, it does not require manual pressure adjustments from a doctor. This can mean fewer sleep studies, appointments, and copays for things like changing pressure! You'll still need to see the doctor for follow-up appointments.

    Built-In Dual-Chamber Heated Humidifier

    By having the heated humidifier included as part of the design, this saves you from the cost of having to purchase a heated humidifier separately. The heated humidifier has multiple adjustable settings so that you can increase or decrease the heat as you like, creating the optimal humidity for your therapy experience.

    Get Therapy Data on the Go with Our Mobile App

    If you want to use your phone to check the status of your therapy, you can use our mobile app to scan the QR code output to the display, getting instant access to your data. This allows you to take your therapy data with you for an instant readout.

    No Compliance Sharing Capability

    For those that don't need or want to share therapy data with outside entities, the Luna II QX Auto is an economical choice, as it has no data sharing capabilities. It provides therapy data for the end-user alone but does not push data into the cloud for insurance companies or doctors to view.

    60-Minute Ramp Time

    Normal ramp times run only about 45 minutes, but for some people, it's not long enough. Ramp time reduces pressure to the lowest setting and gradually increases it over time. It only reaches full pressure up to 60 minutes later, presumably after you've fallen asleep. It's designed to keep you comfortable, helping make it easier to fall asleep.

    Reslex® Expiratory Pressure Relief with Auto Start and Mask Leak Detection

    To start your Luna II QX, you just need to breathe. The device can detect your breathing and can use it as a cadence to start the machine, while the Expiratory Pressure Relief is used to make it easier to exhale. Expiratory Pressure Relief reduces therapy pressure when you exhale, meaning you'll have to use less force to get the air out, and is a comfort feature many machines have. Mask leak alerts are used to tell you when your mask is leaking so you can fix it, and it's an additional feature for the Luna II QX.

    Color LCD Display

    Get up-to-the-minute data about your sleep by using the backlit color LCD display, located on top of the machine. Navigate menus on the LCD display easily using an intuitive turning knob, and see how effective your previous night of therapy was. You'll get vital information about your sleep, without needing to do much extra work.

    Includes SD Card for Storing Data

    The Luna II QX comes with an SD card for storing your data so that you can transfer it to your computer for a more in-depth analysis or share it with your doctor. It's a great way to spot problems with your therapy and find a good solution.

    Cleaning Tips

    It's essential to keep the machine and humidifier clean. While the device itself may not need much cleaning, except for the occasional wipe down, you may notice the humidifier get dirty quickly, especially if using tap water for the humidifier's water supply.

    Tap water has added minerals, fluoride, and impurities, and the quality can vary by locality. As the humidifier adds moisture to therapy air, mineral deposits are left behind, creating a thick, chalky film at the bottom of the tank. This is normal if using tap water.

    Mineral deposit buildup can be resolved entirely if using distilled water. Distilled water has all minerals and impurities removed, and it's not intended for drinking. Because it's free from minerals, the film doesn't form at the bottom of the tank.

    Because the humidifier has a lot of heated standing water, it can quickly grow bacteria. This is why it's essential to clean your CPAP humidifier regularly. To clean a humidifier, please follow these steps:

    1. Using mild soapy water or vinegar, scrub the humidifier, removing all deposits. DO NOT use chemicals such as bleach or household cleaner, as these chemicals may cause poisoning.
    2. When the deposits have been completely removed, allow the tank to air dry.

    Travel Tips

    DO NOT attempt to transport the Luna 2 with water in the humidifier tank. The humidifier tank is not sealed and can cause damage or loss to the device by spilling water.

    The AC power settings on this machine allow it to accept power input from US and International outlets, however, be aware you will need World Traveler Power Adapter Plugs In order to make it work with international outlets.

    QR Code and 3B Luna QR App

    Every night your machine will generate a QR code. This code will appear on the Luna's display, and when scanned with the 3B Luna QR App (available for both Apple and Android), it will generate a report about the previous night of sleep. You can view it on your phone.

    To download:

    1. Open the App Store App on your iPhone, or open the Google Play Store App for your Android.
    2. Search for "3B Luna QR", and locate the result with the name "3B Luna QR" and download.
    3. Once downloaded, open it, and scan the QR code.


    • Tobacco smoke may cause tar build-up within the device, leading to damage or loss of the device.
    • The device is not suitable for high humidity environments (such as a sauna). Please make sure no water enters the device.
    • DO NOT use the Luna 2 around electromagnetic devices, including CT scanners.

    Power Options

    Universal Power

    The Luna 2 Auto will operate on voltages between 100 - 240V AC, meaning it will work with US and International outlets. It will be necessary to buy World Traveler Power Adapter Plugs in order to connect to foreign outlets.

    Freedom Battery

    The Freedom Travel Battery can be used to power the Luna, even while away from an outlet, provided you use a 150 Watt Sine Wave Inverter to convert the battery power into alternating current. The Freedom Travel Battery is FAA approved, meaning it can even be used in-flight!

    Keep in mind, the sine wave inverter will drain the battery faster than it would otherwise, and run times may be lower than expected.

    Portable Outlet CPAP Battery

    The Portable Outlet CPAP Battery converts DC power into convenient AC power, and allows you to plug your machine to the battery using a standard outlet plug. The Portable Outlet is an ideal choice for this machine because you can even power the humidifier without overtaxing the battery.
