Overview

The React Health Luna G3 CPAP (model LG3500) is a fixed-pressure CPAP machine with a built-in heated humidifier, designed to make sleep apnea therapy comfortable and simple. It delivers one prescribed pressure (4 to 20 cm H2O) set by your physician, rather than auto-adjusting.

It includes RESlex exhalation relief, AutoRamp for a gentle start, a quiet motor, and therapy data through the SD card and the React Health Luna QR app. For self-adjusting (auto) therapy, see the Luna G3 Auto.

Important Tips

  • Use the preheat function to warm the humidifier water before starting therapy for added comfort, especially in cooler environments.
  • Adjust Auto Humidity Control to find the moisture level that prevents dryness without causing rainout in the tubing.
  • Set up Auto Ramp to start at a lower pressure and gradually increase once you're asleep, making it easier to fall asleep with therapy.
  • Clean the water chamber and tubing regularly with mild soap and warm water to prevent buildup and maintain hygiene.
  • Replace air filters monthly or sooner if they appear dirty to ensure clean airflow and optimal machine performance.
  • Keep the Luna G3 on a stable, flat surface and away from objects that might block airflow for quiet operation.
  • Monitor therapy data via SD card and share it with your healthcare provider to adjust therapy as needed.
  • Store the device in a cool, dry place, away from direct sunlight and moisture, to extend its lifespan.
  • Check tubing and connections for leaks or wear to ensure proper therapy delivery.
  • Use distilled water in the humidifier to prevent mineral buildup and prolong the life of the water chamber.

FAQs

Is the Luna G3 CPAP fixed-pressure or auto-adjusting?

This model (LG3500) is a fixed-pressure CPAP. It delivers one prescribed pressure all night, set by your physician. If you want self-adjusting therapy, the Luna G3 Auto (APAP) is the auto-adjusting version.

What is the pressure range?

4 to 20 cm H2O, adjustable in 0.5 cm increments, set to your prescription.

Does it have a humidifier?

Yes. It has a built-in heated humidifier with a 360 mL water chamber and a pre-heat function. Use distilled water to prevent mineral buildup.

How do I get my therapy data?

Therapy data is stored on the onboard SD card and can be viewed with the React Health Luna QR app. Built-in cellular is only on the Luna G3 Auto (LG3600), not this fixed model.

How loud is it and how much does it weigh?

It runs quietly at about 28 dBA and weighs about 3.75 lbs, so it is easy to keep on a nightstand or pack for travel.

Do I need a prescription?

Yes. CPAP machines are prescription devices in the United States, so the Luna G3 requires a valid prescription.

What is the warranty?

The Luna G3 carries a 2-year manufacturer warranty.
