The Aprilaire E100V-8199FF dehumidification / fresh air ventilation unit is a whole home system to make todays tighter homes more comfortable and less accessible to mold and VOCs. The E100V dehumidifier can be used alone as a whole home dehumidifier to remove up to 100 pints of moisture per day, or coupled with the 8190FF ventilation kit to offer a true indoor air quality unit. The unit brings fresh air in through the unit and distributes it to the living space while mitigating concerns about bringing in excessive humidity. The on-board control prevents ventilation during the hottest / most humid parts of the day, and automatically compensates by increasing ventilation during cooler periods. The control can be adjusted between 40% and 80% to sense the temperature and humidity levels and adjust the system operation, without wasting energy by locking ventilation during hot/cold periods. The MERV 8 washable air filter removes dust particles while letting fresh clean air in. Units are 1
