Aprilaire Whole-House Dehumidifiers work throughout your entire home. They remove up to 50% more water per kilowatt hour than leading portable dehumidifiers. The Models 1750A and 1770A 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 an Aprilaire Whole-House Dehumidifier installed in your new or existing heating and cooling system.

The purpose of the Aprilaire® Dehumidifier is to keep humidity in the house at acceptable limits to reduce the unwanted effects of high humidity. The dehumidifier gathers data from the HVAC system and measures the condition of the house air to decide when to run. An integrated air cycling feature can activate the HVAC blower to cycle air through the house to balance the indoor conditions. The dehumidifier can also operate an optional ventilation damper to bring in outside air.

The benefits and results speak for themselves:

• Provides three times the moisture removing capacity of leading portable dehumidifiers—up to 135 pints or 16.88 gallons per day

• No messy tanks to empty and clean—ever
   
• Automatically senses moisture levels and maintains optimum humidity levels in your home, never too much, or too little and running only when needed
   
• Switches automatically between whole-house dehumidification when central air-conditioning system is running, and localized dehumidification when your air-conditioning isn’t running
   
• 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
   
• Can be operated manually, allowing you to monitor and control moisture levels in a specific location—such as your basement or master bedroom (optional Living Space Control is required)

“Exposure to mold and dampness in homes as much as doubles the risk of asthma development in children. Anyone with young children in the home should be aware of the potentially harmful effects of long-term exposure to mold and this potential link to asthma in children.”
