The portable Aprilaire 1850F 95 pint whole basement dehumidifier is the latest, most reliable solution to relieve excessive humidity in your basement or larger areas throughout the home. Unhealthy humidity levels, above 50% for a continuous time period, allow mold, mildew and bacteria growth to enter your home, making it particularly dangerous for people with asthma and allergies. Crawl spaces and basements are a major source of air infiltration that permeates up into your living area, bringing odors, allergens and other contaminants along with it. We recommend keeping humidity levels between 35% and 45% to maintain a healthy, comfortable environment for you and your family. This free standing, ultra-quiet portable dehumidifier provides 100% more capacity and 300% more efficiency than any leading portable dehumidifier. Best of all, this unit does not require bothersome and expensive installation work into your HVAC system as compared to other larger dehumidifiers! An internal humidistat will automatically sense moisture levels to maintain optimal humidity levels and reduce and control dampness, mildew, mold, fungi, dust mites and odors. The 1850F model operates down to 40°F and effectively removes 95 pints of moisture per day for areas up to 2,200 square feet with no messy buckets or tanks to empty. Other features include a MERV 8 washable air filter, sturdy, long-lasting construction, and caster wheels for easy maneuverability. This dehumidifier is also equipped with a highly efficient, eco-friendly R410a refrigerant. With our unique Aprilaire 1850F portable dehumidifier, you can now enjoy a comfortable and healthy home for years to come.

Once per hour the dehumidifier will measure the humidity level of the air and compare it to the humidity setting. If the humidity in your home is higher than the setting, the dehumidifier will dehumidify the air until the humidity level drops below the setting.
The Aprilaire Model 1850F is designed to dehumidify the air coming in to the unit by passing the incoming air over an evaporator coil to drop the air temperature below the dew point of the air. Moisture is removed from the air and drained out of the unit to a common floor or waste drain. The air is then reheated in the condenser coil and exits the unit.
Dehumidification occurs until the set point is reached, then shuts off until periodic sampling determines a need for operation.
Under normal circumstances, the filter should be cleaned or replaced once a year. To clean, flush with warm water and detergent solution then let dry.

Please note: When first installed, your dehumidifier has to remove all the moisture that is initially in your home. We recommend setting the humidity level at 55%RH when first installed. Allow the dehumidifier to run until it reaches the setting then adjust the setting to your desired comfort level.
