Keep Humidity under Control with a Dehumidifier

There are various levels of humidity in the air. A higher level of relative humidity, more than 50 percent, in the air can lead to the growth of fungus and mold in homes which can pose health risks, such as asthma and allergies, to a household and also provides an ideal living environment to termites. Dehumidifiers are electrical appliances that are used to reduce the humidity level in the air. These devices are excellent for use in hot and humid conditions where the percentage of water vapor in the air is very high.

The most commonly used types of dehumidifiers are mechanical and desiccant. Mechanical dehumidifiers work by drawing moist air over a coil and a fan. These work best in places where the humidity level is high and warmer temperatures. Desiccant dehumidifiers work by exposing a desiccative substance to an air stream with high relative humidity and do not employ compressors. These are ideal for use in areas with relatively low humidity levels and low temperatures.

Most small areas may only demand a desiccant dehumidifier, but larger areas with humidity issues will demand a mechanical dehumidifier that utilizes compressors or thermo-electric peltiers. Dehumidifiers with compressors feature coils that compressed air or refrigerants move through. These types of dehumidifiers are extremely effective and energy efficient but somewhat loud. Dehumidifiers with thermo-electric peltiers utilize thermo-electric technology by passing an electric current through two dissimilar metals and transferring heat. Thermo-electric dehumidifiers are virtually noiseless because there are no moving parts but are less energy efficient and are only ideal for smaller areas.

While any type of dehumidifier will bring relief to you and your home, it is best to take some time and look at various options available in the market so that you get value for your money. Some recommended features that dehumidifiers should have include:

• Humidistat – Electronic or digital controls that allow you to select or program humidity level.
• Large Tank Capacity – Dehumidifiers with larger tanks work more efficiently than smaller models.
• Washable Air Filter – Most dehumidifiers have an air filter. Choosing a model with a washable air filter will make maintenance easier.
• Hose Connection – Purchasing a dehumidifier with a hose connection makes having to empty the condensed water unnecessary. The hose diverts the condensed water into the floor drain or sump pump.
• Portability – A dehumidifier that features casters or wheels allows you to easily move the unit.
