When spring arrives, so does swap out time,for humidifiers to dehumidifiers. Energy Star dehumidifiers remove the same amount of moisture from the air as conventional models, but use 10 to 20% less energy. For a 40 pint unit, that can add up to savings of $40 per year. Most dehumidifiers have top-mounted air discharge and can be placed against walls, but if you select a model without top-mounted discharge, place the dehumidifier away from walls and furniture, so that air can circulate freely around the unit-and save more energy.
Many utilities offer rebates for purchasing E STAR dehumidifiers.
My advice to homeowners is to purchase larger pint models, as they dehumidify and then their humidistat shuts down the compressor faster, thus saving on energy. Larger pint models, like a 65, 70 or even 75 pint model, will cost you more initially, but they cost less to operate, and save money in the long run.
