In the summertime, the Honeywell Whole-Home Dehumidifier removes excess moisture from the air, making your home feel less sticky and hot. Excess humidity promotes mold growth, condensation, and may even contribute to increased energy usage. Properly dehumidified air is not only healthier and more comfortable, but it can also reduce your summertime energy bills. With less moisture in your home, you can set your thermostat higher and run your air conditioner less. You can save between 5% and 7% on your cooling bill for every two degrees you raise the temperature during the summer.
