    Yes, if you've got damp problems. Broadly speaking, cheaper models have fewer features, a smaller tank capacity and may not be as efficient at water removal. Pricier models typically have a better water-removal capability, higher energy efficiency, more features and a larger tank capacity.

    A dehumidifier that has earned the ENERGY STAR label uses more efficient refrigeration coils, compressors, and fans to remove the same amount of moisture as a similarly sized conventional unit but uses nearly 13% less energy.

    Moisture can build-up inside the crawl space from duct-work condensation, ground moisture evaporation, high outdoor humidity, and more. The dehumidifier is needed to condition the crawl space and ensure healthy humidity levels are kept all year.

    Our dehumidifiers are built to last for more than 10 years, considering the right maintenance and support.

    The best place to put a dehumidifier is in the location closest to the source of the moisture. In multi-level homes, this means that dehumidifiers should most often be placed in basements or upstairs close to the stairs to your basement. This is because the basement is the most humid place in your home.
