React Health G3 X Auto CPAP Machine

Foam-free performance designed for long-term peace of mind.

5-Year Warranty

A 5-year warranty isn't standard in CPAP — most flagship machines, including the ResMed AirSense 11 and AirSense 10, come with two. The G3 X APAP gives you five years of coverage on the main device, the longest warranty in the standard-size PAP category. That's three extra years included with every machine, so you can commit to therapy with confidence.

Humidifier and Heated Tubing

The integrated heated humidifier helps reduce dryness and congestion, with five humidity levels plus an Auto mode that adjusts to your environment. For steadier humidity and help preventing condensation, add the optional G3 X Heated Tubing; it offers five heat levels and helps eliminate water build-up in your hose.

Adaptive therapy

Getting used to CPAP shouldn't feel like a fight. The G3 X APAP tailors pressure to your exact needs for an easier transition into therapy. Smart A custom pressure response adapts to your breathing over a rolling five-session window, while Reslex pressure relief takes the work out of exhaling.

  • Smart A auto-adapts to your sleep apnea needs
  • Reslex pressure relief prevents choking on air
  • Ramp eases you into therapy as you fall asleep
  • Integrated heated humidifier stops dryness
  • Add heated tubing for steadier humidity
First Week Tips
  1. Try Reslex and Auto Ramp to ease into therapy; adjust gradually as needed.
  2. Set your mask type and run the built-in mask fit test before your first full night.
  3. Fill the water chamber with distilled water and empty it daily for best hygiene.
  4. Add heated tubing for steadier humidity and fewer mid-night adjustments.
  5. Check out the full lineup of Luna G3X replacement parts and accessories to stay on schedule.

Ready for travel too: the G3X is FAA compliant for in-flight use and supports built-in 4G cellular connectivity for on-the-go therapy insights.

Compatibility and Quick Setup

How APAP Works

New to APAP? Here’s how the G3 X treats sleep apnea while you sleep.

  1. Your G3 X generates pressurized air to a mask of your choice
    The machine quietly filters air and pressurizes it to help keep your airway open throughout the night.
  2. Pressure automatically adapts to your changing needs
    Exclusive to the G3 X, Smart A technology personalizes therapy by adapting pressure based on your recent sleep sessions.
  3. Humidification adds moisture for comfort
    Integrated humidification helps reduce dryness and support more comfortable nightly therapy, which comes in handy during cold, flu and allergy seasons.
  4. Heated tubing keeps airflow consistent and comfortable
    The heated tubing system helps regulate temperature and humidity throughout the night, so you can sleep uninterrupted.
  5. Connected tools support long-term success
    Built-in connectivity and patient support tools help simplify setup, therapy tracking, and ongoing care, making it easier to stay on top of things.
