Important Tips

  • Use distilled water to prevent mineral buildup and help extend the life of your system and humidifier chamber.
  • After installation, always test the system before use to ensure the auto-refill function and UVC sanitization are working properly.
  • Check the UVC light indicator regularly to confirm that sanitization is active and protecting your water supply.
  • Clean the water chamber and tubing weekly with CPAP Soap and warm water to maintain hygiene.
  • Use a CPAP cleaning brush set to scrub the inside of your tubing and hose connectors thoroughly.
  • Keep the water hose free from bends or kinks to ensure smooth and uninterrupted water flow throughout your therapy.
  • Replace the water chamber every 6–12 months, or sooner if there are signs of wear, staining, or odor.
  • Make sure the CSpring MK3 system is placed on a stable surface to avoid misalignment of the sensor harness or water line.
  • Inspect the water hose and sensor harness periodically for signs of wear or damage, and replace any compromised components promptly.
  • Only use the CSpring MK3 with compatible CPAP models: AirSense 11, AirCurve 11, AirSense 10, AirCurve 10, and DreamStation 2 for reliable performance and proper fit.
  • If you're unsure whether your setup is compatible, visit the CPAP Machines page or contact support before installation.
  • Avoid direct sunlight or high heat exposure to protect the electronics and prevent interference with the UVC light or sensors.
  • Warranty covers 90 days, with returns accepted within 14 days and exchanges available up to 30 days.
