Advanced S/T BiPAP with tidal volume targeting for complex sleep apnea.

The Luna G3 30VT is React Health’s most advanced therapy device, offering spontaneous/timed (S/T) bilevel modes with target tidal volume control. It’s designed for central and complex sleep apnea where standard CPAP or even basic bilevel machines fall short. With five therapy modes, heated tubing included, and cellular + WiFi connectivity, it competes with machines costing $1,000+ more — notably the ResMed AirCurve 11 ASV.

Common Questions

Is it quiet?
Under 26 dBA — the quietest machine in this lineup. Virtually silent at bedside distance, even at higher bilevel pressures.
Is it easy to use?
Dial + color LCD interface inherited from the Luna G3 platform. Straightforward for nightly use, though the advanced therapy modes are typically configured by your sleep specialist.
Can I travel with it?
FAA-approved with universal voltage, but at 3.75 lbs it’s a heavier bedside machine. Comes with a carrying case. Not ideal for frequent travelers.
How does it track my sleep?
Triple connectivity: cellular modem, WiFi, and SD card. QR code phone scan via React Health Plus app. Comprehensive event data for clinician review.
Is the humidifier good?
Integrated heated humidifier with heated tubing included in the box. Preheat function warms the air before you put on your mask. Auto-humidity adjusts to room conditions.
What masks work?
Universal — works with any standard BiPAP/CPAP mask from any manufacturer. Standard 22mm connector.
How much does it cost?
$2,300–$2,700 retail, but significantly cheaper than comparable ResMed ASV devices ($4,000+). Payment plans available (~$399 down + 12 monthly payments).
Who is this NOT for?
Users with straightforward obstructive sleep apnea who respond to standard CPAP or basic auto-CPAP. This is a specialized device prescribed for complex conditions.
