How Dehumidifiers Work

In the simplest of terms, dehumidifiers regulate humidity by removing moisture from the air. This creates living spaces that are comfortable to you but inhospitable to dust mites, mold and other allergens.



First, humid air is pulled into the dehumidifier through the high-efficiency air filter.


It then passes over the evaporator coil. The cold surface of the evaporator coil combined with the humid air forces water to condense and droplets to form on the coil.


This water then drops into the drain pan and runs out of the dehumidifier through the drain tube.


The now cold, dry air passes over the condenser coils and is heated. This warm, dry air is then supplied to the location(s) needing dehumidification.



Fifty percent of the air in the upper levels of your home come from the basement or crawl space. Both contain high levels of moisture that cause musty odors, mold spores, mildew, bacteria and dust mites. Damp air in these areas may also damage the structure of your home and stored items. According to experts, controlling humidity inside the home is essential for comfort, reduced health risks and property protection.
