The Same Great Sleep for $350 Less
You already know ResMed. But the AirSense 11 isn't the only excellent auto-adjusting CPAP. Meet the Luna G3X APAP, its closest match for less.
Two great machines. One is $350 less.
If you've used CPAP for a while, ResMed probably feels like the default. The AirSense 11 is a genuinely excellent machine, and it's the one most people picture when they think "modern CPAP." But it isn't the only game in town.
The Luna G3X APAP from React Health does nearly everything the AirSense 11 does. Same auto-adjusting therapy, same integrated heated humidifier, same heated tubing, same quiet motor, same nightly data your provider can see. Where it pulls ahead: a 100% foam-free design, an industry-leading 5-year warranty, and a price that comes in $350 lower. If you're comfortable looking past the familiar badge, it may be the best value in CPAP today.
The 30-Second Takeaway
- Both are auto-adjusting (APAP) machines that set your pressure for you
- Both include a heated humidifier and heated tubing
- The Luna is foam-free and carries a 5-year warranty (vs 2)
- The Luna costs $999, the AirSense 11 costs $1,349
The side-by-side

Almost all masks fit both machines. Switching brands at the machine doesn't mean switching your mask. Your current ResMed, Philips, or Fisher & Paykel mask will work with either the Luna or the AirSense 11, so you can keep the fit you already like.
Where they're the same
This is the part that surprises people. On the things you actually feel each night, the two machines are hard to tell apart.
They both set your pressure for you. Auto-adjusting therapy means you don't manage a fixed number. The machine reads your breathing and delivers just enough pressure, moment to moment. ResMed calls its version AutoSet. React Health calls its version Smart A. Both do the same job: comfortable, hands-off therapy.
They both keep the air warm and moist. Each machine has an integrated heated humidifier and heated tubing built in, so you get consistent, comfortable air from the machine to your mask with less dryness and less rainout (that pool of condensation in the hose).
They're both quiet, and both connected. Each one runs on a whisper-quiet motor that won't keep a bed partner up, and each transmits your therapy data over a built-in cellular connection, so Easy Breathe or your doctor can review your nights and fine-tune settings remotely. No home Wi-Fi setup required.
Where they actually differ
The gaps between these two aren't in the core therapy. They're in the details, and a few of them may matter to you.
The Luna is 100% foam-free. It's built without the polyurethane sound-abatement foam found in many machines, using a honeycomb structure to stay quiet instead. If foam degradation is something you'd rather not think about, that's a real peace-of-mind advantage.
The Luna's warranty runs longer. Five years versus the AirSense 11's two. On a machine you'll use every night for years, that's a meaningful difference in long-term protection.
The AirSense 11 has the ResMed ecosystem. This is where ResMed's familiarity pays off. Its myAir app gives you a nightly sleep score and coaching, and there's a huge base of users, forums, and clinicians who know the platform inside out. It also offers an AutoSet for Her comfort mode. If you value a polished consumer app and a name your doctor already knows, the AirSense 11 earns its premium.
And then there's price. The Luna lands at $999, the AirSense 11 at $1,349. Same core therapy, $350 apart.
