React Health G3 X with Nova Micro Mask Bundle

Once fully assembled the Nova Micro weighs 1.4 ounces.

The Nova Micro nasal pillow mask is a good option for side sleepers but we don't suggest it for stomach sleeping due to the positioning of the hose connection.

The Nova Micro creates about 21.4 decibels of sound rustling leaves or quiet whispering.

Yes. The G3 X has a built-in humidifier to help with nasal dryness and general irritation. It holds up to 360 mL of distilled water and features 5 humidity levels to help you find your sweet spot. A heated breathing tube is also available as an optional accessory to reduce condensation.

The sound pressure level does not exceed 28 dB, meaning it’s quieter than a whisper. Most people won’t notice the sound, especially once they’re used to it.

Yes, the G3 X works with any CPAP mask using the standard 22mm connection, regardless of brand. For optimal performance, REACT HEALTH recommends using masks from their approved selection or those prescribed by your physician.
Important notes:

• All standard CPAP masks will connect and function
• REACT HEALTH-recommended masks are optimized for device performance and therapy effectiveness
• Your prescribing physician may have specific mask recommendations based on your therapy needs
• Masks should comply with ISO 17510:2015 for verified safety and performance

For complete mask compatibility details, contact your healthcare provider or REACT HEALTH directly.While REACT HEALTH-approved masks offer the best-verified performance, we encourage you to explore different options to find your perfect fit. With our 60-night risk-free trial, you can discover which mask gives you the most comfortable, restful sleep.

Yes. Like all CPAP machines, the G3 X requires a prescription. It's a medical device, and U.S. federal law requires it to be sold on the order of a physician. If you have a diagnosis and a prescription in hand, you're ready to go. If not, don’t worry—we can help.

An LCD screen, a single knob, and two buttons handle everything you need. Auto On means the device starts simply by breathing into your mask—no buttons to fumble with in the dark. The Ramp feature eases you in by starting at a lower pressure and gradually building to your prescribed level, so falling asleep feels natural.

Not every night of sleep is the same, and the G3 X knows that. In AutoCPAP mode, it tracks apnea and snoring events in real time and adjusts your pressure automatically—never dropping below what your doctor prescribed. The optional SmartA feature goes a step further, allowing your clinician to enable gradual adjustments to your baseline settings based on how you actually breathe.

For years, many CPAP machines used polyurethane foam inside the device to reduce noise. Over time, that foam can break down from heat, humidity, and cleaning products—releasing particles into the airpath. The G3 X is the first-of-its-kind standard-size PAP to be engineering completely foam-free, removing the risk entirely.

The G3 X comes with the reassurance of a 5-year warranty on the main device—more than double the standard 2 years. If there’s a defect in how it’s made, REACT HEALTH will repair or replace it. Accidents and misuse fall outside of the warranty, and accessories are covered for 3 months.

cpap.com lets you try any CPAP machine for 60 nights, risk-free. If the G3 X is not the right fit, return it for a full refund or store credit.
