Luna G3 Auto CPAP Machine – Heated Tubing

The Luna G3 Auto CPAP Machine (LG3600) from React Health/3B Medical is a compact, auto‑adjusting CPAP device that delivers both fixed‑pressure CPAP and Auto‑CPAP (APAP) therapy for obstructive sleep apnea. With a pressure range of 4–20 cm H₂O in 0.5 cm increments, it automatically fine‑tunes pressure throughout the night to match your breathing and reduce apneas, snoring, and arousals.

An integrated heated humidifier and standard heated tubing help prevent dryness and rainout, while the pre‑heat humidifier function lets you warm the water chamber before bed so you start therapy with comfortable, moist air. The Auto Ramp feature can be set from 0–60 minutes and uses smart detection to hold a lower, more comfortable pressure while you fall asleep, then gently ramps to your prescribed level.

For easier breathing, RESlex Exhalation Relief reduces pressure slightly when you exhale, making airflow feel more natural and reducing the work of breathing. The device runs at around 26 dBA at 10 cm H₂O, using multi‑stage noise reduction so it remains whisper‑quiet for both you and your bed partner.

The Luna G3 includes a full‑color LCD screen, simple single‑dial control, bedside clock, and resupply reminders, making nightly use and basic navigation straightforward. Built‑in cellular modem plus options like Wi‑Fi module, QR code, SD card, and iCode give multiple ways to send or download compliance and therapy data to React Health’s cloud platforms and smartphone apps. With dimensions around 10.4″ L × 5.7″ W × 4.5″ H, weight about 3.75 lb, and universal 100–240V AC power, it is sized for bedside use but easy to pack for travel.
