If you have respiratory problems, asthma and allergies, a dehumidifier is a great option for controlling moist environments. Creating dry air with dehumidifiers for home use can keep indoor air pollutants at a more manageable level, especially when used in conjunction with an air purifier. Using a dehumidifier can help save money in the long run because it uses relatively little power and can help furnaces and air conditioners operate more efficiently. Read on for tips on buying dehumidifiers for home use.

Using a Dehumidifier:

  1. Excess moisture. Indoor environments with excessive moisture can cause mold and fungus to thrive inside the walls and beneath the carpet. Many types of mold are potentially dangerous and can lead to health problems. A portable dehumidifier reduces the amount of moisture in the air inside a home, which makes it far more difficult for harmful mold to grow. Look for a 30-pint dehumidifier for a compact appliance you can use in an especially moist area, such as a bathroom, or buy a 70-pint dehumidifier if you have more space. A mini dehumidifier is also effective for a small area, such as a hallway or a child's bedroom.

  2. Respiratory problems or allergies. If your home is musty, you'll want to use an air dehumidifier, especially if you have respiratory trouble or allergies. A mini dehumidifier is perfect for using in your bedroom while you sleep, and you can buy a 70-pint dehumidifier for larger rooms or areas in your home, including a living room or family room. The best dehumidifier will have an air vent so it can be placed against the wall or in a corner; if your portable dehumidifier doesn't have a vent, you'll need to place it away from furniture so the air can circulate. Close all windows and doors so your 30-pint dehumidifier will work efficiently.

  3. Basements. If you have a basement that is below-grade, you should use a basement dehumidifier. An air dehumidifier will help you keep the moisture levels in your basement down to manageable levels. By doing this, you can help keep your indoor furnace operating efficiently and even help eliminate minor standing-water problems. In conjunction with a sump pump, a basement dehumidifier can help keep furniture and valuables dry, and it will help keep electronics in proper working order.

  4. Humid climates. In humid climates, such as areas near a beach or large body of water, a whole-house dehumidifier can help keep the environment in your home at a more comfortable level. While the actual temperature won't be affected, you'll sleep more comfortably and may actually save money, since your whole-house dehumidifier can keep the indoor humidity and, thus, your thermostat under control.
