About this tubing
When you use humidification, warm moist air travels down the hose to the mask — and if the hose is cooler than the air, moisture condenses inside it. That's "rainout": the gurgling, spitting, or pooling water that wakes people up. Heated tubing solves it by warming the air along the whole length of the tube, so it reaches the mask at the intended temperature without condensing.
