React Health G3 X Bundles

A React Health G3 X bundle is a complete therapy package: the React Health G3 X Auto-CPAP machine, also sold as the Luna G3 X, paired with a CPAP mask you choose. You get the machine and a fitted mask together, so you can start therapy the night you set it up instead of buying the machine and then hunting for a compatible mask. Want just the machine? Shop the React Health G3 X Auto-CPAP machine on its own.

What is included in a G3 X bundle

Every bundle pairs the React Health G3 X Auto-CPAP machine with one CPAP mask of your choice in your selected size. The machine arrives ready to use with its integrated heated humidifier and heated tubing built in, plus a cellular modem, a reusable air filter, an SD card, the power adapter and cord, a carrying case, and the user guide. Choose your mask style and size on each product page.

React Health G3 X features

The G3 X auto-adjusts your pressure through the night with its Smart A algorithm, and it can also run at a fixed pressure. It is foam-free, built with a honeycomb sound-dampening design instead of polyurethane foam, and runs at under 28 dB. It has a built-in heated humidifier with heated tubing included, Reslex exhalation relief for easier breathing out, and a ramp to ease you into therapy. It sends your data over a built-in cellular connection through the React Health Connect app, and it is backed by a 5-year warranty. The G3 X is FDA-cleared. To learn how auto-adjusting therapy works, read APAP vs CPAP.

React Health G3 X vs the ResMed AirSense 11

Both are auto-adjusting CPAP machines with cellular data and a built-in humidifier. The G3 X includes heated tubing in the box, which is a paid upgrade for the AirSense 11, uses a foam-free design, carries a 5-year warranty, and sits at a value price. The AirSense 11 has the broadest ecosystem and the widest mask and accessory match. The right choice depends on what matters most to you.

Prescription and FSA/HSA

The G3 X is a prescription device, so a valid prescription is required to buy a bundle. If you do not have one yet, an at-home sleep apnea test can start the process, and our team can help. Bundles are FSA/HSA eligible, so you can use pre-tax funds. Your doctor sets your pressure and confirms the right therapy for you.

Which mask should I choose with my G3 X?

It depends on how you breathe and sleep. A full face mask is often chosen by mouth breathers, a nasal mask gives a balanced lower-profile fit, and a nasal pillow is minimal and popular with side sleepers. Your provider can help confirm the right style. Browse all CPAP masks if you are unsure.

Should I buy the bundle or just the G3 X machine?

Choose the bundle if you need a machine and a mask together to start therapy now. Choose the machine on its own if you already have a mask you like; you can shop the React Health G3 X machine separately.

React Health G3 X vs ResMed AirSense 11: which should I get?

Both are auto-adjusting CPAP machines with cellular data and a built-in humidifier. The G3 X includes heated tubing in the box, which is a paid upgrade for the AirSense 11, plus a foam-free build, a 5-year warranty, and value pricing. The AirSense 11 has the broadest ecosystem and mask and accessory match. The right one depends on what matters most to you and what your provider recommends.

Are React Health G3 X bundles FSA or HSA eligible?

Yes. With a prescription, CPAP machines and bundles are generally FSA and HSA eligible, so you can use pre-tax funds at checkout.

What is React Health, and is the G3 X reliable?

React Health, formerly 3B Medical, is a United States manufacturer of sleep and respiratory devices. The G3 X is its current foam-free auto-CPAP, sends data over a cellular connection through the React Health Connect app, and is backed by a 5-year warranty.

Is the G3 X the same as the Luna G3?

Not quite. The G3 X, also sold as the Luna G3 X, is the current foam-free model. The Luna G3 without the X is the prior generation, a different machine. This page is for the G3 X; if you are looking for the older model, see the Luna G3 machine.
