Product Features

Product Features

Ultra Quiet Design

The Luna CPAP machine offers pleasant sleep therapy with fewer disruptions for a more peaceful night's sleep at just 28 decibels—roughly the same as a hushed whisper.

Features You Can Feel Good About

If you're wondering if CPAP machines have alarms that sound when a mask leak is detected, you're not alone. The Luna II CPAP machine has a mask leak warning setting that informs you if your mask slides, which might help you stay on track with your therapy. The device also has RESlex technology, which is a comfort function that provides exhalation pressure relief, making it simpler to exhale against your prescribed pressure without exerting extra effort.

Easily Retrievable Therapy Data

With the ability to communicate your therapy data with your physician over Wi-Fi, you can go to fewer doctor appointments. If you want, you can disable this setting and track your therapy data on your PC, then meet with your doctor in person to discuss the results. If you're a smartphone user, you can scan your sleep apnea therapy data to your QR Code app after each session to get fast access to your therapy data.

Improved Ramp Time

Some people take longer than others to fall asleep. The Luna II features a longer ramp time to help you fall asleep gently, giving you plenty of time to count those final few flocks of sheep. Most CPAP machines have a 45-minute ramp time, but the Luna's ramp feature has a 60-minute timer, giving you a few more minutes to feel comfortable and fall asleep.

User-Friendly Design

You can rapidly navigate the menus on this device's full-color LCD screen to alter your settings or retrieve your therapy data.

Important Tips

Important Tips

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.


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.

Replacement Schedule:

  • Hose: Replace Every 6 to 12 Months
  • Reusable Filter: Replace Every 6 Months

Using Your New Luna II CPAP for the First Time:

When your Luna II CPAP first arrives, there is no need to set the therapy pressure, as this was done before we shipped it to you. As you unpack the box, you'll find the hose, cord, humidifier chamber, reusable filter, and the Luna II along with a few other accessories.

To prepare your Luna II CPAP for the first use, you'll need to follow these instructions.

  1. Connect the hose to the machine and your mask, ensuring the connections are tight on both.
  2. Install the reusable filter.
  3. Fill the humidifier chamber with distilled water.
  4. Connect the power cord and plug it into the appropriate wall outlet and then plug the cord into your machine.
  5. Press the therapy on/off button on top of the machine to start therapy.

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 gets 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.

Replacing the Filter:

The Luna II CPAP uses a reusable foam filter that needs to be inserted into the filter cover assembly. The filter cover assembly can be found on the bottom left corner of the machine. Here's how to change the filters:

  1. Eject the filter cover by pulling it out and away from the device.
  2. Remove the current filter and replace it with a new one.
  3. Snap the filter cover assembly back into place.
