Exactly How Does a Dehumidifier Work? What You Must Know

A dehumidifier works by removing excess moisture from the air and in that way it lowers the humidity. Dehumidifiers are used in homes to regulate the humidity and thereby creating better indoor environments and at the same time removing the threat of mold, dust mites, and other allergens. In a way dehumidifiers work very much like air conditioners or refrigerators. The moisture in the air enters the dehumidifier and is collected in a bucket or drip pan for disposal while the air is reheated slightly before it exits. The air that is reheated exits the dehumidifier maximizing the dehumidifier's efficiency.

A dehumidifier will only remove humidity from the air, and it won't cool the air in a room as some people believe. It just makes the environment in the room comfortable so that you don't feel the stickiness that usually accompanies excess humidity. Dehumidifiers are typically needed in rooms where there are no air conditioners. That's because an air conditioner is a kind of dehumidifier, so there's really no need to install a dehumidifier in rooms that are air-conditioned. It is used mainly in the damp areas of the home such as the basement.

The dehumidifier has a fan that blows the air over its cold coils. As the water condenses on the coils it drips into the bucket or drip pan. The drier air is then released across the coils back into the room warmer and drier than before. The water that is collected in the bucket or drip pan should be emptied regularly, if not depending on the model it might shut down the dehumidifier to avoid water spillage.

Whenever there is an excess of moisture in the air this can cause for an uncomfortable indoor environment. It has been found that as much as 20 pints of excess moisture can be added to a home's indoor air. Also, many appliances in the home such as washing machines, dryers, and dishwashers can contribute to the moisture condition inside the home. This can lead to humidity problems and condensation.

If your home has good ventilation and it feels dry, then you probably have no need for a dehumidifier. But, if your home gets condensation on the windows in winter and it feels humid or you have a mildew or mold problem, then these are symptoms of excess moisture in the air. And you need to get a dehumidifier before things get worse.

Also, if someone from your home is an allergy or asthma sufferer, then obtaining a dehumidifier is an excellent choice. That's because it can help reduce the amount of allergens that grow in your home and it can help to also reduce the risk of asthma. Excess humidity can also threaten your health because it can worsen ailments such as rheumatism and arthritis.
