The Luna G3 Auto from React Health (formerly 3B Medical) prioritizes comfort and efficiency—as evidenced by its included heated tubing, PM2.5 air filter, auto-ramp functionality, and accessory and supply reminders. This auto-adjusting positive airway pressure (APAP) device intuitively changes your pressure settings as needed, so you can get a good night’s sleep no matter your pressure needs.

Adjusting to CPAP is easier than ever with weekly Care Check-Ins, Test Drive therapy sessions, and an expanded coaching library.

"I love it! Easy starts, not loud at all, seems to respond better than my 10. Suggest trying this if you have been using the 10 for years like me. You won’t regret it!"

I am brand new to CPAP. One week into therapy and my experience with the Luna G3x is really great. I have been able to sleep between 6.5 to 9 hours on CPAP.

Very good machine
Positive: The water container is easy to open, fill and close, not true of ResMed Dreamstation. A full report of past nights is readily available. The pricei is MUCH lower than ResMed Dreamstation.
Negative: There is no utility so send reports to my physician. The heated hose must be specific for this unit. Others do not work.
1. Terribly bright lights that auto turn on. Not able to turn off or even dim back light. The best you can do is have it turn off automatically after 30 seconds. 30 seconds of light bright enough to illuminate my bedroom in the middle of the night is awful. Who ever thought that was a good idea? My unit is now outfitted with black electrical tape. I taped an aluminum card over the screen so that I can flip it up to see it if I need.
2. They lock down the data and make it inaccessible. No using OSCAR to get sleep data. They just give a compliance "report" from what I can tell.
That's my experience after one night. If anything else comes up, I'll update.
The water chamber on this cpap is a piece of crap. It has always been hard to put on and remove, so I leave it on for 6 months. My husband is trying to get it off now. He is using a hammer and screwdriver and it still won’t come off! Now a piece of plastic has come off and cut his arm. Don’t buy this cpap!!!!!!
