  • Out of Stock - This item is not currently available to order.

  • Product Overview

    Stop mold damage, relieve your allergies, and stay comfortable throughout your home with the Aprilaire 1730A Whole House Dehumidifier. Unlike portable dehumidifiers that dehumidify limited areas in your home, the 1730A works with your HVAC system to dehumidify all of your rooms evenly and efficiently. The 1730A is rated to remove 65 pints of moisture per day at AHAM conditions (80 degrees F, 60% humidity) and covers homes up to 1,400 square feet. With multiple installation options and foolproof humidity control, this unit is ideal for smaller homes, townhouses, and condos.

    Multiple Installation Options

    The Aprilaire 1730A installs as part of your central HVAC system. As your system runs, the dehumidifier pulls air in using the return ducts, dehumidifies it, and sends dry air back into your rooms. Popular installation locations include an equipment room or closet, your basement, or your attic. Hanging installation is also possible. Two 8-inch duct collars are included for ducting air return and supply, and the supply duct can be installed in 1 of 2 locations on the unit for more flexibility in your space. The system can also run independently as a standalone dehumidifier, dehumidifying air in a single space.

    *For proper installation, it's best to consult with a qualified HVAC technician.

    Automatic Humidity Control

    Take the guesswork out of controlling your home's humidity. The Aprilaire 1730A automatically maintains your set humidity level in true "set it and forget it" fashion. To set it up, program your desired humidity level between 30 and 80% (between 45 and 50% is ideal for maintaining a healthy, mold-free environment). Periodically, the dehumidifier's humidistat measures the humidity level in your home and adjusts dehumidifying speed to maintain that level. This frees you from the hassle of manually adjusting operation based on your own humidity measurements.

    Additional Features


    Made in the USA

    • Wall-Mountable Dehumidistat - The onboard dehumidistat is detachable and easily wall-mountable to help you control the humidity setting more conveniently.
    • MERV-8 Air Filter – This easy-to-access, washable air filter removes allergens such as mold spores and dust particles while ensuring efficient operation.
    • Auto Defrost Control – In cool conditions, an automatic defroster turns off the compressor and runs the blower until the coils are defrosted to protect the unit from damage.
    • No Water Tank - The Aprilaire 1730A features a drain port to gravity drain collected condensate (drain hose not included). This eliminates the often messy task of emptying a water container.
    • Leveling Feet - Four stabilizing rubber feet are included to ensure proper drainage of the dehumidifier.
    • American-Made - All Aprilaire dehumidifiers are proudly made in the USA.


    The compact Aprilaire 1730A Whole House Dehumidifier is a one-stop solution for controlling mold-causing humidity throughout smaller homes.

    What Customers Love

    • Low Maintenance - Just wash the filter and clean debris from the drain port and hose annually to ensure proper operation.
    • Very Efficient - Compared to leading portable dehumidifiers, the 1730A operates up to 4 times more efficiently and removes 50% more moisture per kilowatt hour.

    Things to Consider

    • Drain Location - For gravity drainage, you'll need a nearby drain and vinyl or PVC drain tubing (0.75-inch diameter). If there is no nearby drain, consider using an external condensate pump to pump water to a more ideal location.
    • Large Homes - The 1730A is designed for smaller homes up to 1,400 square feet. For larger homes, consider the Aprilaire 1750A, which covers up to 2,200 square feet.
