Dehumidifiers are most often found in the basement of homes where excessive moisture and dampness can be a big problem. By keeping relative humidity down to between 30 and 50 percent, dehumidifiers help stop the growth of microorganisms and keep the air feeling comfortable.
Too much moisture in the air can be as damaging as too little. Instead of itching caused by uncomfortable dryness, humidity above 50 percent can cause itchy skin and nasal passages due to mold debris and spores that are floating around. Wet conditions are a breeding ground for mold, mildew and dust mites. Prolonged moisture can even cause water damage and rot.
How dehumidifiers work
The majority of dehumidifiers use a removable water reservoir to collect moisture. They let users know when this is full through an indicator light and often shut off automatically. Some come with a hose connection that can be directed into a floor drain so that emptying isn't needed. Different types of dehumidifiers can have a big impact depending on where your home is located geographically and how bad the moisture problem is. We'll give you information on the top dehumidifier brands, as well as provide you with tips for proper use and maintenance to keep your dehumidifier running in the best possible condition.
One of the biggest issues with dehumidifiers is energy consumption. A non-energy-efficient machine can use as much electricity as a refrigerator - a lot more than most other products you'll find in the home.
Whether or not a dehumidifier is Energy Star rated should be an important factor for those looking to solve moisture problems. The more-efficient products will reduce energy consumption by at least 10 percent over others. A 40-pint machine can save up to $20 a year if it's Energy Star rated, enough to pay for itself in as little as five years.
Buying a dehumidifier with a high "energy factor," as we explained on this site, can ensure you're getting the most moisture-reducing performance for your money.
