Room Dehumidifiers Help You Stay Cool

Room dehumidifiers can help cool down a room, especially in areas typified by the popular phrase: “It’s not the heat, it’s the humidity.”

Most people know that room dehumidifiers can make damp areas such as basements feel more comfortable by taking excess humidity out of the air. But a room dehumidifier also works to help you feel cooler in warm, humid regions.

A room dehumidifier won’t work as well as an air conditioner to cool down a room when temperatures reach 90 degrees and above, but it can work with an air conditioner in high temperatures to help pull humidity out of the air. Combine an Energy Star-rated air conditioner with an Energy Star -rated room dehumidifier and you may lower your electric bills during the dog days of summer. In milder temperatures, a room dehumidifier lowers the humidity in a room to make you feel cool and comfortable.

How Do Room Dehumidifiers Work?

A dehumidifier uses a small, motorized fan to draw air into the unit, where the air passes over two refrigerant-filled coils. One coil is cool and one is warm. The reaction caused by the air simultaneously meeting hot and cold temperatures condenses water from the air. The water collects into a bucket that is either completely enclosed or sticking out of the dehumidifier. Some room dehumidifiers connect to an external drain by means of a hose, saving the homeowner trips to the bathtub with full buckets of water.

Many dehumidifiers use drainage hoses that work merely by means of gravity, which means that your drainage area must sit lower than the dehumidifier. Some use a condensate pump that can send water ten-to-twenty feet upwards and away from the source.

Look for energy-efficient features in your room dehumidifier to keep your home cooling costs down. A model should have:

  • An Energy Star rating
  • An on/off switch to quickly turn off the unit when you leave the room
  • A humidistat that lets you program a humidity level between 30 and 50 percent, which is the optimal range of humidity for most people
  • A timer so that you can run the unit overnight during off-peak electricity hours, or set it to turn on a little while before you come home from work to create a comfortable house.

What else can room dehumidifiers accomplish? A room dehumidifier:

  • reduces potential mold and mildew problems by eliminating the moist environment in which mold and mildew thrive
  • helps preserve wood furniture, door frames, etc., which can fall prey to warping in high humidity
  • keeps room humidity between 30 and 50 percent, which creates an optimal environment for people’s comfort and health

With all of these benefits, it’s not surprising that many people rely on room dehumidifiers to handle at least a portion of their home-cooling tasks.
