Cutting the cost

Shut the room's windows and doors so it isn't fighting a fresh supply of damp air, and empty or plumb the tank so it doesn't keep cutting out and idling. Set a sensible target humidity rather than the driest possible setting, and run it only where damp is a genuine problem. Clean the filter regularly. Fixing the source of the moisture cuts the run time more than any setting can.
