Energy Factor

• The energy factor of a dehumidifier is a measure of the volume of moisture, in liters (l), that it removes from the air for each kWh of energy it consumes. Standard-capacity dehumidifiers typically start at around 1.2 l/kWh, while high-capacity humidifiers can reach up to 3.5 l/kWh or more.
  
  

Considerations

• The energy factor of a dehumidifier is slightly different from the energy factor of other domestic appliances. The energy efficiency of a washing machine or refrigerator is typically quoted as kWh per month or year, so the lower the figure the better. The higher the energy factor of a dehumidifier, the better.
  
  

Energy Star Standard

• The Energy Star standard defines the energy factor for dehumidifiers at 80 degrees and 60 percent relative humidity. In economic terms, the higher the energy factor of a dehumidifier, the less you pay to remove moisture from the air.
