Offers a Small Footprint That Won’t Clutter Nightstand

The modem for the G3 Auto is built directly into the machine, helping you save space on your bedside table. This machine weighs less than four pounds, so it’s easy to pack and take with you if you want to use it as a travel CPAP machine.

Great Option for Allergy Sensitivities

If you struggle with seasonal allergies, dust, or pet dander, the Luna G3 APAP comes with a hypoallergenic PM2.5 filter, which is one of the most efficient and highest-arresting air filters of any CPAP machine! Coupled with the included heated tubing, the Luna G3 provides some of the cleanest and most consistently-heated therapy air available. 

Includes Comfort Controls to Preheat Your Humidifier and Help Prevent Rainout

With a simple tap of the screen, enhance your comfort with the integrated preheat setting, which is designed to warm your humidifier before you jump into bed. This device is outfitted with AutoHumidity control as well thanks to the included heated hose, which will help prevent rainout even if you select the highest moisture level.

Sleep Peacefully While the Auto Ramp Feature Makes Any Necessary Adjustments

The auto ramp function on the G3 senses when you are about to fall asleep and adjusts the pressure accordingly. As you sleep, the G3 makes adjustments to your pressure settings if changes in airflow are detected. The ramp time for this machine ranges from 0 to 60 minutes to help you gradually reach your pressure settings and fall asleep with ease.

Quiet Operation Won’t Disturb You or Your Partner

When working at a pressure of 10 cmH2O, the G3 APAP Machine operates at less than 28 decibels—which is quieter than a whisper. 

Provides Easy-to-Access Reports and Supply Reorder Reminders

Equipped with a user-friendly screen that gives you easy access to your personal CPAP settings and nightly sleep reports, this device can help limit the frequency of your doctor check-ins. When in standby mode, the modern interface displays the time, temperature, and humidity level, so you can check in on your settings with a quick glance. Considered a newer feature, the G3 APAP Machine also lets you know when you should replace your air filter or mask to ensure you have the most up-to-date and highest performing equipment.

Tracks and Stores Data for You and Your Doctor

You can use your Wi-Fi to store and send your sleep apnea therapy progress from an SD card or smartphone, making it a breeze for your doctor to learn if your pressure prescription is adequate or if you could benefit from an adjustment.
