Description

With increased energy efficiency and higher pint capacities, the AprilAire E100 Dehumidifier E-series dehumidifiers are premier whole-house models. Keep your dehumidifier out of the way and quiet by ducting one of these Aprilaire dehumidifiers to your HVAC system.

 

This compact dehumidifier can cover homes, crawl spaces, basements, and other spaces up to 5,200 square feet when ducted.

For a complete bundle with everything you might need, consider the Aprilaire E100 100-Pint Energy Star Dehumidifier + Basement Package or the Aprilaire E100 Wi-Fi Enabled Whole House Dehumidifier + Basement Package. This bundle includes an Aprilaire E100 100-Pint Energy Star Dehumidifier, a Digital Dehumidifier Control (Non-Wi-Fi package only), a low-profile condensate pump with a 20-foot hose, a hanging kit, and a replacement filter.

Versatile Installation Options

The E 100 series dehumidifiers are suitable for any environment. They can be ducted or used as standalone units.

  • E100: Standard 100-pint HVAC dehumidifier with an 8-foot power cord for plug installation. Does not include a drain hose.
  • E100C: The 100-pint model includes casters for more portable and standalone installations. An 8-foot power cord is included for plug installation, and a drain hose is provided.
  • E100H: Need to hardwire your dehumidifier? The E100H is designed to be hardwired for long-term use. This model does not include a drain hose.

The AprilAire E series 100-pint dehumidifiers are compact enough to fit anywhere. Each unit stands at 14 x 15 x 26 inches.

Wi-Fi Enabled Version

The AprilAire E100W model offers a Wi-Fi-enabled dehumidifier that eases setup, pairing, and monitoring through the AprilAire Healthy Air App. This version of the E100 dehumidifier has a Wi-Fi-enabled digital controller with an onboard color display, which can be used to set and change its settings.

More Capacity, Less Operating Cost

An upgrade to the popular AprilAire 1850 series, these dehumidifiers remove more moisture with less energy usage. The greater performance means healthier air for homeowners. Its Energy Factor at AHAM is 2.35 L/kWh, earning it the Energy Star Most Efficient 2024 recognition. This recognition is for the dehumidifiers with the latest technological innovations and most efficient designs.

Ducting Options

Common installation locations include an equipment room, closet, basement, or attic. Hanging installation is also possible. Two 10-inch duct collars are included for ducting air return and supply, and the supply duct can be installed in one of two locations on the unit for more flexibility in your space.

Additional Features

  • On-Board Humidity Control: Use the buttons to adjust the setting from 40 to 80 percent. Typically, customers initially set it to 55 percent and then adjust it up or down based on their feelings.
  • Automatic Sensing: Your dehumidifier will automatically sense the air and compare it to your humidity setting, then adjust its operation as needed.
  • Air Filter: Remove dust and other impurities before air travels through the dehumidifier and back into your space.
  • Auto Defrost Control: In cool conditions, an automatic defroster turns off the compressor and runs the blower until the coils are defrosted to protect the unit from damage.
  • Adjustable Outlet Options: The duct collar is adjustable for top or side discharge applications.
  • Drain Hose Included With E100C: The 10-foot drain hose and easy attachment included with the Aprilaire E100C allow you to drain water to another location.

Note: AprilAire strongly recommends professional installation for this dehumidifier.

    Nice, High Quality Dehumidifier

    Prior to buying this unit, I had a Santa Fe dehumidifier. It worked well but only lasted 6 years. For what it cost, it should've lasted much longer. I decided to try AprilAire this time. Hopefully it lasts longer. I have a large full basement under a ranch style house and the dehumidifier is installed there. This unit seems to run much less often than the Santa Fe did and keeps the basement dry. I like that it samples the air every hour rather than just kicking on and running the compressor. I think this should give it more longevity. It is noisier than I was expecting. It make a pulsing noise when running that transmitted to the living space. I connected a big metal tee duct that acts kind of like a muffler and directs the noise out the sides of the tee rather than straight up to the floor above. I no longer notice the noise in the living space anymore.

    Finally able to maintain proper humidity!

    I was running a 40 pint a day consumer grade dehumidifier and it ran constantly and never made a dent in the humidity in my basement.

    Got this big boy and it keeps it steady!

    Great Unit

    Just purchased this to replace a Santa Fe 90 that finally gave out. This unit is extremely easy to set-up, quiet, and incredibly consistent with the humidity control. I set it at 50%, and the actual reading on monitors I have in my crawl space are all spot-on at 50% and never fluctuate. Great feature that they designed in, such that a p-trap is not required. Just drain directly down into a condensate pump.
