React Health Luna G3 CPAP Machine with Heated Humidifier

The React Health Luna G3 CPAP (model LG3500) is a fixed-pressure CPAP machine with a built-in heated humidifier, designed to make sleep apnea therapy comfortable and simple. It delivers one prescribed pressure (4 to 20 cm H2O) set by your physician, rather than auto-adjusting.

It includes RESlex exhalation relief, AutoRamp for a gentle start, a quiet motor, and therapy data through the SD card and the React Health Luna QR app. For self-adjusting (auto) therapy, see the Luna G3 Auto.
