The BMC G3 C20 CPAP Machine is a fixed‑pressure device designed for treating obstructive sleep apnea with comfort and convenience in mind. It features an integrated humidifier with a pre‑heat function, heated tubing to prevent condensation, and Reslex technology that eases exhalation by reducing pressure. The machine operates quietly at under 26–28 dB, includes auto ramp to adjust pressure as you fall asleep, and offers accessory reminders for mask, tubing, and filter replacement.
