The Aprilaire Model 1870 series dehumidifiers are the perfect product for whole-home dehumidification, basements and sealed attics.

Automatic Humidity Sensing On-board humidity sensing allows for better whole home monitoring and control of humidity. Optional remote living space control can be used to provide additional humidity control accessibility, as well as increased reliability in coastal environments.

Systems Status On-board LED status, providing instant, easily understood feedback / validation on the unit's operation and performance.

Innovative Features:

Air Filtration - MERV 8 Washable filter included

Built-in Ventilation:
  • Brings in outside air for ventilation of the home to ASHRAE 62.2 2010 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 2010 standard).

The new Aprilaire 1800 series models are truly an entire dehumidification solution in one box, includes everything you need for base installations.

Optimal/Most Efficient Solution For Whole-home Humidity Control:

Aprilaire Central Dehumidifiers monitor conditions 24-7, ready to tackle the toughest humidity conditions within the home at any time.
  • During partial load conditions, often prevalent within the home
  • During those days and times where there is not a need or call for cooling:
    • Spring and Autumn months
    • Cloudy and rainy days
    • Nighttime and morning hours
  • When high humidity is an issue/problem in specific areas of the home
  • When dependable, reliable 24-7 humidity control is critical to the health of your family

Using an Aprilaire Central Dehumidifier independently as well as in conjunction with your existing central air conditioning system optimizes the overall dehumidification of your home as well as the energy efficiency of your cooling system.

The Model 1870 and 1870W have the ability to bring in fresh air. Fresh air will dilute stale air and pollutants and will reduce humidity in the winter months. The fresh air is brought in through a 6" round duct and 6" round normally closed damper. The dehumidifier has built in controls to adjust the amount of fresh air that is brought in.
