Many years ago, desiccant dehumidifiers were not nearly as efficient, powerful or reliable as compressor models and in many cases the length of time they could continue to offer quality performance was almost always questionable. Because of this, compressor or refrigerant style dehumidifiers have dominated the dehumidifier market for decades as the first choice for the large majority of consumers.
However, dehumidifier manufacturers have made amazing advancements in desiccant technology and now offer many desiccant dehumidifier models that are on par if not better than compressor models. If you are looking for a high-quality dehumidifier there is no longer any reason to avoid desiccant based models. In fact, they offer several unique advantages over compressor dehumidifiers that can offer owners much a much better value in certain circumstances.
What is a Desiccant Dehumidifier?
Desiccants have natural properties that promote a dry environment. They naturally soak up moisture from the air much like a sponge soaks up water from a table or floor. Desiccant dehumidifiers typically use zeolite or silica gel along with a fan and rotators to draw air through the unit. As the air passes through the unit, the desiccant naturally absorbs the moisture.
Are Desiccant Dehumidifiers Better or Just Different?
Determining if a particular style of dehumidifier is better than another often depends on how, where and how much the unit will be used. Therefore, generally speaking, desiccant models are simply different compared to compressor models, although they can offer certain advantages in the right environments.
Desiccant dehumidifiers tend to be lighter, smaller in size and significantly quieter than compressor units. Because the do not have all the mechanical parts required to run a compressor model, the weight and size of even more powerful models offer easy portability. Additionally, they are much quieter which makes them a great fit for areas that require a certain limitation on noise level such as an office space.
Models that are based on desiccant technology use a different scale for determining their effectiveness and efficiency of moisture removal. The metrics for what is considered average, good and poor performance are less demanding than compressor models. This means they are probably not the best choice for extremely warm and high humidity environments.
However, if you live in a mid-range temperature and humidity climate or a cold climate with low to mid-range humidity, then many desiccant models would be a perfect fit for your needs. In fact, just to save you the time and frustration of starting your search from scratch, we have included a brief review of several desiccant dehumidifier models below. We believe the models listed below offer consumers some of the best overall values available on the market.
