What is the difference between the G4600 and the G46002?
The G4600 includes the G3 X APAP machine with built-in heated humidifier, heated tubing, and cellular modem. The G46002 is the same machine with cellular modem but without the heated tubing included. If you want heated humidification with rainout prevention straight out of the box, the G4600 is the right choice.
Does the React G3 X contain polyurethane foam?
No. The G3 X is the first standard-size PAP machine available in the U.S. engineered completely foam-free. Instead of degrading polyurethane sound-abatement foam, it uses a unique honeycomb design that stays quiet (under 28 dBA at 10 cm H₂O) without off-gassing or particle release.
What therapy modes and pressure range does the G3 X support?
The G3 X supports both fixed CPAP and Auto-CPAP (APAP) modes across a pressure range of 4–20 cm H₂O. In Auto mode, the exclusive Smart A algorithm continuously adapts pressure to your breathing needs throughout the night.
What masks and tubing are compatible with the G3 X?
The G3 X is compatible with any standard 22mm CPAP mask, regardless of brand — including nasal, nasal pillow, and full face masks. It accepts standard tubing, Luna G3 heated tubing, and SlimStyle tubing. Select the correct tube type in settings to optimize humidification.
How does the cellular connectivity work, and do I need Wi-Fi?
The G4600 includes a built-in 4G cellular modem that transmits therapy and compliance data to cloud-based platforms for remote monitoring by you and your provider — no Wi-Fi setup required. You can also view data on-screen, via the React Health Plus app (iOS/Android) using iCodeQR, or stored on the included SD data card.
What is included in the box?
The G4600 package includes the React G3 X Auto-CPAP machine with built-in heated humidifier, humidifier water chamber, 6-foot heated tubing, two reusable foam filters (one pre-installed), universal AC power supply with cord, SD data card, carrying case, and user manual.
Is a prescription required?
Yes. Federal law requires a valid prescription from a licensed physician before this device can be shipped. You can upload your prescription after checkout.
How long is the warranty, and is there a trial period?
The G3 X includes a category-leading 5-year manufacturer's warranty on the main device (accessories carry a 3-month warranty). The device is intended for single-patient use on adults over 66 lbs / 30 kg for whom CPAP therapy has been prescribed.
