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.
