Ways to spend less

  • Set the humidistat to the highest humidity you are comfortable with rather than the lowest setting; it will run far less.
  • Keep doors and windows of the room closed while it runs.
  • Clean the filter and coils so it removes water faster per hour of running.
  • Cut its running time by two hours a day. Saves about $7.81 a month in season.
