    Do I need a prescription to buy the Luna G3X?
    Yes — in the United States, all CPAP and APAP devices are classified as prescription medical devices. You will need a valid prescription from a licensed physician or sleep specialist before we can dispense the unit.

    Tip: If you have already had a sleep study, your provider can write the prescription quickly. Call us and we’ll guide you through what you need.
    Is the cellular modem included, or is it an extra cost?
    The cellular modem is built into the Luna G3X (G4600) — it is not an add-on or accessory. It automatically sends your nightly sleep data to the Luna Connect platform so your care team can monitor your therapy. There is no Wi-Fi to set up and no Bluetooth pairing required.

    Tip: Ask us about any cellular data service fees specific to your provider arrangement before purchase.
    What is the difference between CPAP and APAP?
    A standard CPAP delivers one fixed pressure all night. An APAP (Auto CPAP) — like the Luna G3X — automatically adjusts air pressure breath by breath based on your actual breathing needs. Many users find APAP more comfortable because it only delivers the pressure needed at any given moment.

    If you are unsure which mode is right for you, your prescribing doctor will specify it. Call us and we can help you understand the difference.
    Does the Luna G3X come with a heated humidifier and heated tube?
    Yes — both are included in the box. The Luna G3X G4600 comes with an integrated heated humidifier and a heated tube already included. No separate purchases required.

    Tip: Always use distilled water in the humidifier chamber to prevent mineral buildup and extend the life of the unit.
    What is “rainout” and does the Luna G3X prevent it?
    Rainout happens when warm, humid air from the humidifier cools inside an unheated tube and turns into water droplets. You may feel a gurgling sound or a splash of cold water near your mask — not comfortable.

    The Luna G3X’s heated tube keeps air warm all the way from the machine to your mask, which eliminates rainout in most sleeping conditions.
    Can I travel with the Luna G3X?
    Yes. The Luna G3X is compact and uses a universal power supply (100–240V), so it works with international outlets when paired with a plug adapter. The device also auto-adjusts for altitudes up to 2,500 meters — no manual setting changes needed.

    It is generally allowed as a carry-on medical device on commercial flights. Check with your airline and TSA for their current rules.
    What masks work with the Luna G3X?
    The Luna G3X is compatible with standard 22mm CPAP tubing, which covers the vast majority of CPAP masks on the market — including nasal masks, nasal pillow masks, and full face masks.

    Tip: Call us and we can help you find a compatible mask that fits your face shape and sleep style. Getting the right mask fit is one of the most important steps in successful CPAP therapy.
    How do I clean and maintain the Luna G3X?
    General maintenance is straightforward:
    • Daily: Empty and rinse the water chamber. Let it air dry.
    • Weekly: Wash the chamber, tube, and mask cushion with mild soap and warm water. Rinse thoroughly.
    • Monthly: Inspect the air filter and replace if gray or clogged.
    • Always: Use distilled water in the humidifier to prevent mineral buildup.

    Refer to the official Luna G3X User Manual for complete cleaning instructions and replacement schedules.
    Does Medicare or insurance cover the Luna G3X?
    CPAP and APAP therapy is generally covered by Medicare and most private insurance when medically necessary — meaning you have a diagnosis of obstructive sleep apnea confirmed by a sleep study. Coverage rules vary by plan and require specific documentation from your doctor.

    Call us and we can help you understand what information you will need to submit a claim. We are not able to guarantee coverage outcomes — always verify benefits directly with your insurance provider.
    How quiet is the Luna G3X at night?
    The Luna G3X operates at approximately 26 dBA at a mid-range pressure setting — roughly equivalent to a soft whisper or leaves rustling. Most users and their bed partners report not noticing it once they fall asleep.

    Noise levels may vary slightly based on pressure setting, mask seal quality, and room conditions.
    Do you offer store pickup or local delivery for the Luna G3X?
