Product Features

Product Features

Built-In Heated Humidifier

During CPAP therapy, heated humidification allows patients to sleep better and longer without experiencing dry mouth or pain. The Luna G3's humidifier is integrated within the machine, making it considerably smaller and easier to use than other humidifiers. You can choose from a range of humidity levels ranging from 1 to 5, with 1 being the lowest and 5 being the most.

RESlex Exhalation Relief Technology

When you enable RESlex Exhalation Relief, your Luna G3 will detect your breathing rhythm and relieve pressure in the mask during exhalation, making you feel much more comfortable. RESlex can be adjusted to off, 1 (lowest setting), or 3 (maximum setting) (highest setting).

Audible Leak Detection

If a leak is discovered while your Luna G3 is in use, the machine will emit an audible alert after 40 seconds to wake you up and notify you of the leak. A Leak!!  warning will also appear on the LCD panel.

Automatic CPAP Supply Reminders

You can set reminders for changing your Mask, Tube, and Filter on the Luna G3 for 30, 60, 190, or 365 days. For example, if you pick a 60-day reminder to change your Mask, your machine will sound an audio alarm and display a message that says Please Change Mask! on the 60th day. This function can also be disabled.

Luna Usage Score and Summary

The Luna G3 will display a Usage Summary and Usage Score on the screen after each sleep therapy session so you can see how your most recent treatment went. The overall score can be up to 100 points, with 75 being excellent, 74-55 being acceptable, and anything less than 54 being in need of improvement. A breakdown of usage time, mask seal, and respiratory episodes is included in the summary. All of this is also accessible simply scanning the QR code on the screen and using the 3B Luna QR App.

3B Luna QR Mobile Application

The 3B Luna QR app, which is available for iPhone, iPad, and Android, allows you to take your compliance data with you everywhere you go. Simply scan the iCodeQR produced on your Luna G3 mobile after the program has been downloaded to your device. A summary of your compliance data is saved in your app in seconds and is available whenever you need it!
