If you use a Luna G3 APAP machine for sleep apnea therapy, this is worth checking tonight, not next week.
BMC Medical Co., Ltd. announced a recall on September 7, 2026, and the FDA published it on September 8, 2026. The issue affects the Luna G3 APAP, model LG3600, running firmware version G3-2.00.76.
The FDA has classified this as a Class I recall — the agency’s most serious category, reserved for situations where using the product could cause serious injury or death.
Why This Recall Matters
Here’s the specific failure: when the device is operating under high pressure, a high respiratory rate, and high peak flow at the same time, it can display an error message and then shut itself off automatically.
For anyone using an APAP for sleep apnea, a mid-sleep shutdown means therapy failure exactly when your breathing needs support most. The FDA has not received reports of injury connected to this defect, but the risk is serious enough to warrant its top classification.
How Many Devices Are Affected
BMC says 20,160 devices have already had their firmware updated. But an estimated 196 units may still be running the defective G3-2.00.76 firmware.
The affected devices were manufactured between September 11 and October 18, 2024, and distributed nationwide between October 29, 2024, and July 6, 2026.

Don’t just stop your therapy without a plan — talk to your doctor first. Here’s the process:
