An ENERGY STAR-qualified dehumidifier removes the same amount of moisture as a similarly sized standard unit. With more efficient refrigeration coils, fans and compressors, they use up to 20 percent less energy than standard models.
Facts and Product Knowledge
- Models are available that are rated for use at temperatures as low as 42 degrees Fahrenheit.
- The energy efficiency of a dehumidifier is measured by its energy factor. In general, a higher energy factor means a more efficient dehumidifier.
- For maximum dehumidification and energy efficiency, properly size the space to be dehumidified and the conditions that exist in the space.
- Shop for a model that has a humidistat, allowing you to set the desired relative humidity level for a room or area in your home.
- For better operation of a non top-mounted air discharge unit, place the dehumidifier away from walls and furniture so that air can circulate freely around the unit; and away from dust and dirt, which can clog coils and grills.
- Doors and windows to the space being dehumidified should be closed while the unit is running to ensure that the space is dehumidified as efficiently as possible.
