Aprilaire High Capacity Basement & Crawlspace Dehumidifier.  Removes up to 90 pints / day.

  Free Indoor Digital Hygrothermometer included with each 1700FS Dehumidifier

The ultra-quiet Aprilaire High Capacity Basemen & Crawlspace Dehumidifier is the newest, best solution to humidity problems in your basement. The 1700FS is easy to install - and does not have to be connected via ductwork to your HVAC system.

Excess humidity in the air can cause basements to be smelly, musty and noticeably damp. Nobody wants to go there, play there, be there. Excess humidity can damage basement furniture and furnishings, cause wood to swell and fabric to rot. Stored items grow mildew and wall paneling peels. High basement humidity can lead to health threatening conditions too. Any basement with relative humidity regularly above 60% can become the perfect breeding ground for a variety of pathogens like mold, mildew and fungi.

Common portable dehumidifiers are a weak answer! Off-the-shelf portable dehumidifiers don't perform well in cooler basement environments and you typically need more than one to treat your entire basement.

The solution is a dehumidifier designed exclusively for basement use - the Aprilaire 1700FS High Capacity Dehumidifier. More than your standard portable unit, the Model 1700FS High Capacity Dehumidifier is in a different class altogether. It provides 100% more capacity, and 300% more efficient operation than the leading portable dehumidifier.

The Aprilaire Model 1700FS Whole-House Dehumidifier works throughout your entire home. It's Energy Star® rated, removing 50% more water per kilowatt hour than leading portable dehumidifiers. The Model 1700FS also features truly automatic control, so there's never a need to manually control the dehumidifier - just set it once and forget it!

The best choice for healthy, comfortable air is the Model 1700FS Whole-House Dehumidifier installed in your new or existing heating and cooling system. The benefits and results speak for themselves:

  • Provides three times the moisture removing capacity of leading portable dehumidifiers-up to 90 pints or 11.25 gallons per day
  • Has no tank to empty - unit can be attached to home's water drainage system with 1" PVC pipe.  Can also be gravity drained into floor drain or sump pit.  Can use optional condensate pump to pump water up to a sink.  Click here for more info on condensate drainage.

  • Convertible from whole-home to localized application lets you solve excess moisture issues where you need it most from crawl spaces to attics and basements
