React Health G3 X Auto-CPAP Machine with Heated Humidifier

React Health G3 X Auto-CPAP Machine with Heated Humidifier

If you want sleep apnea therapy that just works without fiddling with settings, the React Health G3 X adjusts your pressure automatically through the night, giving you the support you need and not more. It is also the first standard-size foam-free PAP available in the U.S. (per React Health), built without the internal sound-abatement foam that has been on a lot of CPAP users' minds lately.

You get both auto-adjusting and fixed-pressure modes, gentle relief on every exhale, and a ramp that starts you low and eases up to your pressure while you fall asleep. This G4600 comes ready to use with the integrated heated humidifier and heated tubing, so the air reaches you warm with less water buildup in the hose, plus a built-in cellular modem that keeps your care team in the loop. It is backed by a 5-year warranty and is FSA/HSA eligible.

A prescription is required.
