The CSpring MK3 Automatic CPAP Water Chamber Refilling System is a smart device that keeps your humidifier topped up automatically. It connects to your existing water chamber using a lid adapter and sensors, making it easy to integrate into most CPAP setups without needing to refill manually.

No more late-night refills or waking up to a dry system, this setup does the work for you.

It uses a built-in UVC light to help maintain water quality and BPA-free materials for safer use. By managing humidity levels consistently, it helps reduce dryness and makes therapy more comfortable with less effort.

  • 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.

    Review Date: 2025-12-11

    Customer Feedback:

    If you’re running out of water in your cpap machine daily, this is the water chamber for you. My husband used to run out during the night and would wake up to the smell of no water. Works great to store a large amount of distilled water.

    Review Title: Terrible experience

    Customer Rating: 1 out of 5 stars (Poor)

    Reviewer Name: Rebecca A. (Verified Purchase)

    Review Date: 2025-11-23

    Customer Feedback:

    I bought two of these within this year for 2 locations. The one that is 7 months old no longer works because the sensors will not connect to the machine. I contacted the manufacturer 3 times in 2 weeks and no response. Finally today they say the warranty doesn't cover problems unless it is a defect. This is definitely a defect. It is very fragile in several areas and will not last long. Unfortunately, I learned the hard way. Terrible manufacturing support and this senior citizen is out $300. Costly mistake.

    The white sensor holders on the reservoir that you attach the leads to don't stay closed. They need to be redesigned. Also i can't find replacements on internet. \nIf anyone knows where i can buy new ones please let me know.

    Review Title: Works great

    Customer Rating: 5 out of 5 stars (Excellent)

    Reviewer Name: Kathryn L. (Verified Purchase)

    Review Date: 2025-07-23

    Customer Feedback:

    We ordered this product because my adult daughter could not independently replenish the water reservoir to her CPAP machine. This product is expensive but so worth it for both of us. Because we travel I thought the purchase of another CSpring could eliminate the need to transport back and forth. We place the order and before it arrives, I called Sleep Play and spoke to a professor customer service rep who agreed with my suggestion of ordering a another reservoir so we did. We used it this past weekend and we traveled a lot lighter! When the second C Spring was delivered we called and explained our situation and because we had not opened it Sleepplay accepted our return and issued a return for nearly the total amount we paid for it. All the staff we have delt with were patient and knowledgeable of our medication equipment needs and we look forward to working with them again

    There was a couple of nights that i would forget to refill my tank and would wake up dryer than the Sahara. I love this so much! No more nightly refills or risking running out of water if i sleep in.

Find Solution

Why do CPAP machines have humidifiers?

CPAP humidifiers add moisture to prevent dry mouth, throat irritation, and nasal congestion caused by pressurized air.

Are all CPAP humidifiers the same?

No, there are two types: - Integrated humidifiers (built into the CPAP machine) - Standalone humidifiers (separate units that connect to the CPAP)

Do I have to use a CPAP humidifier?

No, but it helps reduce dryness and discomfort. If you experience dryness, adding a humidifier can improve comfort.

What type of water should I use in my CPAP humidifier?

Use distilled water to prevent mineral buildup and bacteria growth. Avoid tap or bottled water.

How often should I clean my CPAP humidifier?

Daily: Empty and rinse with warm water. Weekly: Wash with mild soap, rinse well, and let it air dry.

Why is there water in my CPAP mask or hose?

This is rainout, caused by humidified air cooling in the hose. Using heated tubing or a hose cover can help.

Can I travel with a CPAP humidifier?

Yes, but some travelers prefer to turn off the humidifier to reduce bulk. If flying, empty the water chamber before packing.

When should I replace my CPAP humidifier chamber?

Every 6 months, or sooner if you notice discoloration, cracking, or buildup that doesn’t clean off.
