1. A method of controlling air flow through a dehumidifier having an air mover and a moisture removal device, the method comprising:

  • operating the air mover at a first speed to direct air flow into thermal contact with the moisture removal device while ambient air surrounding the dehumidifier is at a first ambient condition that includes a first humidity, wherein air flow through the dehumidifier has a first dwell time at the moisture removal device with the air mover operating at the first speed;

    sensing a change from the first ambient condition to a second ambient condition that includes a second humidity less than the first humidity and below a threshold humidity value; and

    in response to the change, automatically operating the air mover at a second non-zero speed that is slower than the first speed to increase the first dwell time of air flow at the moisture removal device to a second dwell time.
