Excess humidity in the air can cause homes 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 - they don't perform well in cooler basement environments and you typically need more than one to treat your entire home.
The solution - This Aprilaire Central Dehumidifier is designed specifically to control humidity inside the whole home as well as in crawlspaces and attics. Built-in duct collars alow for easy connection to the central HVAC system. This dehumidifier automatically and continually measures the true measure of moisture level, dew point. The unit operates to control humidity to the dryness set point that is either set on the unit or on the optional living space control. A built-in, automatic air cycling feature can be utilized to activate the HVAC fan to cycle the air throughout the whole home for proper balance for comfort. This dehumidifier also has a patented, built-in ventilation feature, which will allow fresh air to be brought into the home from the outside. In utilizing this feature, the dehumidifier will dehumidify the incoming air, if needed (based on dew point / dryness set point), as the outside air is first entering the home. The built-in ventilation feature is designed to be able to meet ASHRAE 62.2 Standard for Ventilation.
The Aprilaire Model 1770A 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 1770 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 1770A Whole-House Dehumidifier installed in your new or existing heating and cooling system. The benefits and results speak for themselves:

Comments about Aprilaire 1770A Ductable Dehumidifier:
This unit appears to be well built and can support a number of different types of installation. My use is primarily to dehumidify a 1500sf finished basement. I had been using smaller units you can get at any of the big box stores, but they'd only last a couple of years and quit working plus they ran non stop and often couldn't maintain RH below 60%. The 1770A was fairly easy to install myself in my HVAC utility room where I was able to cut intake/exhaust ducts that connect to the unit with insulated flex duct. The utility room has a floor drain so I was able to drain the unit without the use of a pump. NOTE: this unit does require a dedicated 20 amp circuit. With my electric panels in the same utility room and room for additional circuits this was a pretty easy task to add another breaker and receptacle.
