In the hot summer months, humidity can build up rapidly in your home.  This not only can make you uncomfortable and sticky, but can also cause mold and mildew to grow.  Additionally, that humidity damages wood floors, musical instruments, etc.

While central air conditioning units can help dehumidify your home, sometimes a little extra help is needed – either for your whole house or just for certain rooms.  Here we explore three different types of dehumidifiers and compare them.

Different Types of Dehumidifiers

As mentioned, there are three different types of dehumidifiers.  Two of them are portable dehumidifiers that can serve a single room or even smaller area.  They are:


Determining the best ideal dehumidifier for you needs can seem overwhelming. The table below compares the three types of dehumidifiers:

Portable refrigerant Portable desiccant Whole house
Energy consumption Consume less energy than desiccant dehumidifiers Consume more energy than refrigerant units Consume energy as part of HVAC system
Moisture extraction Extract more moisture than desiccant models Extract less moisture than portable units Extract more moisture
Cold temperature functioning Do not operate as well in cooler climates Work best in cooler climates Work in all climates
Portability Can be moved Can be moved Cannot be moved
Installation Professional installation not needed Professional installation not needed Professional installation needed
Cost Less expensive than whole house dehumidifiers initially Less expensive than whole house dehumidifiers initially More expensive than portable dehumidifiers initially
Best for Rooms kept at a constant moderate temperature Colder weather Large residences (as well as commercial and industrial properties)
Not good for Colder weather Warmer weather, as refrigerant units are more energy efficient People on a budget


In conclusion, all three types of dehumidifiers can do what they are supposed to do.  While you have to decide which is right for you, in general, if you are going to be in your home for several years, the whole house humidifier is the way to go.
