A dehumidifier is an appliance that removes excess moisture from the air. These devices are often used in areas like basements and crawl spaces, where high humidity levels can lead to mold growth, musty odors and other issues related to poor air quality.
But what exactly does a dehumidifier do and how can it help your home? Here’s why you should consider a dehumidifier for basements and crawl space areas in your home.
What Is a Dehumidifier and What Are Its Benefits for Basements and Crawl Spaces?
A dehumidifier removes excess water from the air. It does this by drawing in humid air, cooling it, removing moisture (AKA water vapor) and blowing out dry air. Dehumidifiers come in all sizes, so you can find one to fit any home or budget.
The primary benefit of using a dehumidifier in basements and crawl spaces is that it helps reduce excess moisture; which is especially important in these areas that are prone to moisture issues. All of which can lead to mold growth and musty odors.

Additionally, reducing humidity levels can help improve energy efficiency since moist air takes more energy to heat or cool than dry air.
Finally, using a dehumidifier in basements and crawl spaces can help protect the structural integrity of your home by preventing condensation build-up on surfaces like walls and floors.
The Different Types of Dehumidifiers and What Might Work Best for You
Choose a dehumidifier for the space and conditions, not just its technology label. Compare rated moisture-removal capacity, operating temperature, drainage and efficiency. A large basement or crawl space does not, by itself, establish which model will work best. For a cool space, check the manufacturer’s minimum operating temperature and defrost requirements. ENERGY STAR’s buying guidance explains these factors.
A direct evaporative cooler is not a dehumidifier. Passing air through a wet pad cools it by evaporating water into the airflow, adding moisture rather than removing it. Do not choose this type of cooler to solve a damp-basement problem. The Department of Energy’s HVAC guide, section 3.4, explains the distinction between direct and indirect evaporative cooling.
Whole-home dehumidifiers typically connect to ductwork to treat one or more rooms. They are not automatically the best or lowest-cost option for every basement or crawl space. Ask a qualified installer to assess moisture sources, the area to be treated, sizing, drainage and installation requirements before selecting equipment. Most whole-home units require a drain rather than a bucket that you empty. Review ENERGY STAR’s whole-home guidance.
Commercial Dehumidifier for Basements and Crawl Spaces
Commercial dehumidifiers come in all shapes and sizes, with some featuring high-powered fans to draw out the most moisture possible.
They also have adjustable humidity settings, auto shut-off capabilities, adjustable fan speeds and filters for improved air quality.
By controlling the humidity level in your basement or crawl space, you can help protect your home from potential damage caused by moisture and reduce the risk of mold growth or other health hazards caused by excessive dampness.
How To Choose the Best Basement Dehumidifier for Your Home
When selecting a dehumidifier, it’s important to consider not only size but also energy efficiency ratings. Larger units tend to consume more energy while smaller ones may be less effective overall.
