How this dehumidifier scores for different use cases
Covers up to 5,500 sq ft with 100-pint daily capacity and ducted installation. The wall-mount control enables whole-house management from any room.
100-pint capacity and auto-defrost make this ideal for basements. Continuous drain and remote wall control let you install it and forget it in damp basement environments.
Listed for commercial and residential use with 100-pint capacity, MERV 8 filter, and corrosion-resistant aluminum coils. Ducted design suits commercial HVAC integration.
No Wi-Fi, no app control, and no voice assistant support. The Model 76 wall control offers remote operation but lacks modern smart home connectivity.
This is a whole-house ducted unit weighing 64 lbs with no sleep mode, no wheels, and no handle. It is not designed for bedroom placement.
At 64 lbs and 26 inches wide, this commercial-grade unit is far too large and powerful for closets, RVs, or small spaces.
Our Verdict
The AprilAire E100 Pro is a serious whole-house dehumidifier. It pulls 100 pints of moisture per day and covers up to 5,500 square feet.
This is a ducted, permanently installed unit. You connect it to your home's ductwork, set a target humidity, and walk away.
The included Model 76 wall control lets you adjust settings from upstairs or another room. That solves the crawlspace and basement access problem nicely.
You get auto-defrost, continuous gravity drain, and a washable MERV 8 filter. These features keep maintenance low over time.
The missing pump drain means you need a floor drain or external condensate pump. Plan your drainage before you install.
At $2,225, this costs far more than portable dehumidifiers. You pay for commercial-grade capacity and ducted whole-house coverage.
No Wi-Fi or app control limits remote monitoring to the wall panel. Tech-savvy buyers may find this disappointing.
This unit fits homeowners with serious moisture problems in large homes. If you need a portable bedroom unit, look elsewhere.
What We Like
- Removes 100 pints of moisture per day, enough for very large or very wet spaces
- Covers up to 5,500 square feet, one of the largest coverage areas available
- Includes Model 76 wall-mount control for remote humidity management from another room
- ENERGY STAR Most Efficient certified, helping reduce electricity costs despite high capacity
- Corrosion-resistant aluminum coils and washable MERV 8 filter extend the unit's lifespan
What Could Be Better
- No built-in pump drain, so you need gravity drainage or an external pump
- No Wi-Fi or app control for remote monitoring from your phone
- No wheels or handles on a 64-pound unit, making it hard to move after installation
- No sleep mode or timer for scheduled operation in living spaces
- Price of $2,225 is significantly higher than most residential dehumidifiers
