Model 1750A/1770A Model 1730A Model 1710

Enable your customers to take control of their total comfort, health, and home's sustainability with the all new whole-home humidity control solution from Aprilaire.

Optimal/Most Efficient Solution For Whole-home Humidity Control

“Tight” Home Construction

Homes built with a foam seal, glazing, icynene, and/or other new environmental barriers provide optimum energy efficiency.

In these tighter homes, moisture and VOCs build from washing, cooking, and other activities. There are typically few ways to remove the moisture that is now trapped on the inside.

Air Conditioning Efficiency

Air conditioners are more efficient than ever before, cooling the home quickly with as little power consumption as possible. In tighter homes, air conditioning systems can run on partial load conditions well over 90% of the time, which means less run time, therefore less dehumidification. Overcooling is usually a last resort to get needed dehumidification.

Using variable-speed or advanced air-handling technology to gain additional dehumidification is another option, however, it typically lowers the energy efficiency of the system; a system designed to optimize cooling.

Portable Solution versus Whole-home Solution

A portable unit treats the air in just one room.
To get the ultimate health and comfort benefits from a portable homeowners would have to purchase one for every room in their home. 		A better, more convenient solution is to install an Aprilaire central dehumidifier. As part of the home's heating and cooling system, it installs away from the living space and operates silently

Industry leading 5 year bumper-to-bumper warranty

Extreme Durability - 15+ year system life expectancy due to core design improvements as a direct result of continued extensive life-cycle testing, including application of vibrations, frequency harmonics, and forces up to 60g. In addition, Aprilaire dehumidifiers have undergone extensive coastal condition testing on electronics and controls.

Extremely Quiet - averages less than 55 dB; quieter than a person-person conversation

Practical Design

Simply heating and cooling a home is no longer what drives sales in the HVAC contractor's world. Differentiation is the key to future success. Humidity control is one of the keys to this success as well as what homeowners are requesting. By quoting and installing products that offer a whole-home dehumidification solution, many contractors are thriving in today's challenging economy.

Thanks to Aprilaire, whole-home dehumidification has become a simple, cost effective and profitable option to just cooling alone. With the introduction of our new "size-friendly" 1730A 65 pint model, Aprilaire has completed its family of easy-to-install, whole-home dehumidifiers offering a range that covers 65 through 135 pint units.

Model 1710A-1750A-1770A

Innovative Features

Air Filtration - MERV 8 filter included

Built-in Ventilation

  • Brings in outside air for ventilation of the home to ASHRAE 62.2 2007 standard.
  • In hot, humid climates, supplemental dehumidification of fresh air beyond standard HVAC equipment is recommended.
  • The most efficient means to dehumidify air is upon initial entry into the home instead of after the home is loaded.
  • Monitors HVAC fan run time during cooling and/or heating calls to efficiently ventilate the whole home, and automatically monitor/control the humidity of the incoming air; utilizes dehumidifier and HVAC fan to make up any remaining ventilation required based on chosen set point.
  • Optional outdoor temperature sensor can be used if no fresh air is desired above 100°F or below 0°F (utilizing this will ignore ASHRAE 62.2 2007 standard).

The newest, best solution to humidity problems in your basement.

The Aprilaire Model 1710A High Capacity Dehumidifier:basement use.

  • • More capacity
  • • More efficiency
  • • More convenience


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, causing 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 molds, mildew and fungi. Dust mites, another leading allergen, need as little as 50% relative humidity to thrive and infest your home.

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 basement.
