The summer season can bring high levels of humidity causing a lot of discomfort to many people and their homes. To solve this problem, it is recommended that a dehumidifier be used. This device not only maintains the proper level of humidity to enhance comfort in the home but also prevents the onset of many other problems.
Humidity or water vapor present in the air above 50 percent can cause the growth of mildew, dust mites and mold that leads to allergies and asthma. Molds and mildew can thrive and discolor clothing as well as natural wood furniture. They grow practically everywhere resulting in damage to your personal belongings and property. But with a dehumidifier, these problems can be well prevented.
How it works
A dehumidifier uses a fan to draw room air via its two sets of refrigerant-filled coils -- one cool and the other warm -- thereby eliminating moisture. The built-in fans blow the humid air over a refrigeration system resulting in the process of condensation.
The water that condenses out of the air then drips into a bucket inside the device. What is left of the dry, warm air is eventually blown back into the room. The unit can, however, be connected to an external drain so there's no need to empty the bucket each time it's filled.
Dehumidifiers can slightly increase the air temperature. But many latest models now are now made to vent out the back of the unit to prevent warm air from being blown directly to the living room. According to experts, dehumidifiers are effective when used to an indoor temperature of 65 degrees Fahrenheit. Lower temperatures can cause some units to build up ice making them less efficient.
Benefits
A good dehumidifier should help eliminate dust, pollens and smoke from the air using an air purification system. These harmful elements are the major causes of allergy and asthma as well as other respiratory problems.
With this device, moisture can be controlled in the home. Keep in mind that one family can build up a maximum of 15 liters of moisture in a single day through breathing, cooking, bathing, heating and drying clothes. During the hot summer months, moisture builds up in wall linings, roofs, furnishings and framing and anywhere it can be absorbed.
Buying tips
The size of a dehumidifier should be based on the condition of the area and the size of the room. The most popular size is one that has a capacity of 30 to 50 pints. For the basement, a large unit that can collect more water is ideal. There are some units, though, that have a drain. For the bathroom or closet, a mini dehumidifier may be used. Before buying your unit, first determine the capacity you need. A larger dehumidifier is recommended by experts because it works quickly and more efficiently.
Take into account as well the storage tank capacity. The tank serves as a collector of condensed water and it varies in size.
To prevent the storage tank from overfilling, choose a unit with an automatic shutoff feature. Get a unit with an adjustable humidistat to control the level of humidity in your home. If this feature is not built in, an option is to purchase a separate hygrometer that will show the humidity level of the air.
