Humidifiers and dehumidifiers are appliances that increase and decrease, respectively, the humidity in a room. Maintaining relative humidity levels is important for your health and for the condition of your home and your belongings.

Humidifier Function

A humidifier uses a fan to draw air and pass it through a moist filter. The resultant humidified air is returned to the room and, in turn, contributes moisture to the surrounding dry air.

Humidifier Benefits

Humidifiers are used in enclosed spaces with very dry conditions. Excessively dry air can cause dry skin and breathing problems, notes Humidifier-Review.com, as well as increased symptoms in those with allergies.

Dehumidifier Function

A dehumidifier draws in moist air and passes it first over cold coils, where moisture in the air condenses into a collecting tray for removal. The air then passes over hot coils that restore the air to its previous temperature.

Dehumidifier Benefits

Dehumidifiers are beneficial for comfort, health and damage control in your home. Excessive humidity can cause feelings of bodily overheating, dangerous moulds and structural damage to your home and items that are sensitive to moisture, according to Sears.

Dehumidifiers vs. Air Conditioners

Air conditioners and dehumidifiers both remove humidity from the air. Dehumidifiers are preferable in certain situations, such as when a cooling effect is unneeded or in basements, where there is often no window for an AC exhaust. Otherwise, an air conditioner is usually sufficient for controlling humidity.
