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 $11.67 a month in season.
