Designed for mid-sized homes humid climates, the Aprilaire 1850/1850W dehumidifier is the newer, more-environmentally friendly version of the 1750A. This version runs earth-friendly R-410A refrigerant and has a MERV 8 rating.

This unit has a capacity of 95 pints (~12 gallons) per day! It also works perfectly for crawlspace applications.

The Aprilaire 1850 is a refrigerant dehumidifier. A powerful blower inside the unit draws air into the cabinet, filters and removes moisture from the air, and then discharges the dry air to the home.

Inside the cabinet, a sealed refrigeration system (R-410A) removed moisture by moving the air through a series of tubes and fins that are kept colder than the dew point of the incoming air. The condensed moisture drips into the drain pan, and then to a drain tube routed to the nearest floor drain.

After the moisture is removed, the air moves through a second coil where it is reheated before being sent back into the home.


  • Low Maintenance - just once a year filter cleaning
  • Quiet operation, installed away from living space
  • The onboard dehumidistat is detachable and easily wall-mountable
  • True automatic digital control - set it once and forget it!
  • Dehumidify homes up to 5,200 square feet with a single system
  • Back by 5-year warranty (must be installed by licensed contractor to be valid)

Please Note:

For gravity drainage you will need a nearby drain and either PVC or vinyl drain tubing (3/4" diameter). You can use a condensate pump if there is no nearby drain.
