With flow-through type humidifiers, any unevaporated water from the evaporator pad runs off into the drain pan and flows through to a household drain.

This is a key feature of flow through humidifiers, since unlike reservoir humidifiers (ultrasonic or impeller / drum types) where water stands for a period of time, flow-through humidifiers will not allow bacteria to develop.
