Dessicant Dehumidifier
A desiccant dehumidifier is different from standard models of dehumidifiers in the method they use to pull humidity from the air and the amount that they can pull. The EPA recommended amount of air humidity is 30 percent to 50 percent, any higher or lower than that can cause respiratory problems in many people. Desiccant styles of dehumidifiers are best used at relatively low humidity levels to get the best results.
These dehumidifiers utilize desiccant materials such as silica gel to pull in moisture in the form of water vapor. The humidity is pulled in and turned into vapor and stored inside the internal reservoir. The great point about these units is that if the room humidity reaches levels below 30 percent they will expel some of the stored vapor until the room's humidity level is between 30 to 50 percent. So while they are dehumidifiers, they are also humidifiers in their own right as well.
These are extremely useful for households in areas that do not have stable weather year-round. In the summer it can be unbearable sticky, while in the winter it can be dry enough to dry the skin all over your body. A desiccant dehumidifier is a cost-effective and convenient way to feel comfortable in your home at any time of the year.
Because of the way desiccant dehumidifiers pull in and push out water-dense air there is little need to empty out the internal reservoir like there is in regular units. There is also less of a need for maintenance because of this feature, making it extremely convenient if you just don't have to time to take it to the repair shop. Another plus is that when it is warm, the air that the dehumidifier expels acts as a cooling agent and helps keep the surrounding area at a comfortable temperature and humidity.
Be sure to do some research and shop around before deciding on any one specific unit for your home. These are fairly complicated machines and there is a lot to know before you bring one into your home. Not only that, but the prices greatly fluctuate between brands and models so browsing brands and retailers is a good idea. Once you find one that you feel will serve you well for a good amount of time and is reasonably priced you are well on your way to owning one of the most convenient household climate devices you can buy. Desiccant dehumidifiers are not to be underestimated: they are far more useful than their name implies. Once you have used one for at least a year you will not even be able to figure out how you lived without one before.
