Does A Crawl Space Dehumidifier Works?
Crawl space dehumidifiers work to remove water in the buffer between the wet ground and the living areas in the home above.

Where Should I Place A Crawl Space Dehumidifier?
If you have a narrow storage or utility space in your home or office, a crawl space dehumidifier is a great solution. It makes that space a little more pleasant when it needs to be accessed.
Crawl spaces are often poorly insulated, and rarely accessed. They are usually only used when there is a problem elsewhere in the structure. This makes them vulnerable to the elements, promoting mold growth and allowing in air that will encourage excess indoor humidity. It also means that by the time you notice a problem, it could have progressed quite far.
Controlling the humidity in your crawl space also makes the environment less favorable to pests, including insects that thrive in high humidity areas.
Dehumidifiers placed in a crawl space perform two specialized functions to work most effectively in that particular space. Look for one with a strong fan to push air throughout the entire space and one which is compact enough to fit in this cramped area but still allows airflow over the whole unit.
