Dehumidifiers are appliances that are used to decrease the moisture content of air in humid climates. Apart from their use as household appliances, they are also popular in the medical community. They work with the help of a fan which blows warm air on cold metallic coils. Moist air is pulled into the dehumidifier, where condensation results in water droplets that drip into a storage tank or drain through a hose. Therefore, it primarily works on the scientific principle of condensation.
When humidity is too high, it tends to create an atmosphere that is prone to several household problems, including medical issues. Often, improper ventilation and other environmental factors result in building up of air moisture. Dehumidifiers for homes are available as stand-alone units or combined with other household devices. An air conditioner is an example of the latter model, as it dehumidifies the air automatically, in the process of condensation to cool down the room temperature. Dehumidifiers come in a two types, namely mechanical and desiccative. Mechanical dehumidifiers have both hot and cold coils, where the air is drawn over the cold coil to condense moisture, while the dry air passes over the hot coil to bring it back to the original room temperature. Desiccative dehumidifiers use a desiccative substance which is exposed to an air stream, so that its affinity for water draws the moisture. Desiccative models do not have compressors and are preferred in areas of low humidity and low temperatures. Mechanical models are more efficient and expensive.

There are several factors to be considered while purchasing a dehumidifier namely, size, portability, drainage facilities and other automated features. The size is usually based on the quantity of moisture extracted in a period of twenty-four hours, and it is measured in pints. A larger capacity model covers more area within a short span of time. A portable unit is preferable if you are likely to move the unit between different rooms. It is light and compact with rolling casters or a carrying handle. All models come with a storage tank to collect the condensed water, so that the tank can be emptied periodically. If emptying the tank seems to be a hassle, you can opt for a continuous drainage model, which consists of a hose attached to the unit to allow the moisture to drain out.
If the dehumidifier is to be used in temperatures below 65o F, it is better to choose a model that comes with an anti-frost sensor to prevent quick working cycles and keeps out frost accumulation on the sensor. Washable or removable filters simplify the maintenance task, as the dust particles trapped in them can be washed off easily. A built-in humidistat automatically turns the unit on or off in accordance to the humidity setting. Dehumidifiers for home also come as basement dehumidifiers, which can be installed in the basement to eliminate moisture from the basement’s atmosphere.
Dehumidifiers help eradicate dust mites that cannot be removed by insecticides and pest removal methods, as they thrive well in humid environments. Excess humidity also promotes the growth of mold and mildew. As there are notable health reasons for using a dehumidifier, it is a worthwhile investment.
