This helps create a calm and soothing environment for sleep. Additionally, the blue light serves as a helpful indicator to easily locate the humidifier in a dark room. So, if your Crane humidifier is blinking blue, it means it’s in sleep mode, providing a peaceful and restful atmosphere for your sleep.
