Luna G3 BPAP 25A Bi-Level CPAP Machine with Cellular Modem with HT EA
The React Health Luna G3 BPAP 25A is an advanced bilevel PAP device designed for the home treatment of obstructive sleep apnea in adults. Offering CPAP, AutoCPAP, S and AutoS therapy modes across a wide pressure range of 4 to 25 cmH2O, it adapts precisely to individual therapy needs night after night. The integrated heated humidifier with auto-adjust and preheat functions prevents dryness and rainout, while RESlex exhalation relief ensures naturally comfortable breathing throughout. At just 1.7 kg and operating below 26 dB, this BiPAP machine is compact, quiet and built for everyday home use. Cloud connectivity via iCodeConnect and the React Health PLUS app gives patients and clinicians easy access to detailed compliance and therapy data.
Key Features
- Four therapy modes - CPAP, AutoCPAP, S (Spontaneous) and AutoS for flexible, individually tailored therapy
- RESlex exhalation relief - syncs with the patient's breathing to reduce pressure during exhalation for a more natural therapy feel
- Integrated heated humidifier - auto-adjust and manual settings (levels 1-5); preheat function warms water before therapy starts to eliminate cold initial airflow and reduce rainout
- Heated tubing compatible - reduces condensation and maintains consistent airflow temperature throughout the night
- Auto Ramp - adjustable up to 60 minutes, gradually increasing pressure to ease the transition to sleep
- Leak alert - activates after 40 seconds of detected leak to help users address fit issues quickly
- Smart supply reminders - alerts when filters, tubing and masks are due for replacement
- 3.5-inch full-colour LED touchscreen - intuitive menu navigation, easy to use in low light
- Multi-stage noise control - operates at or below 26 dB(A) for a peaceful sleeping environment
- iCodeConnect cloud platform - enables easy sharing of compliance data with healthcare providers
- React Health PLUS app - patients can review nightly summaries and long-term therapy progress on mobile devices
- SD card data storage - included for local therapy and compliance data recording
- Compact and lightweight - 1.7 kg with integrated humidifier; fits easily on a nightstand
