The AprilAire E100W Wi-Fi Dehumidifier is a 100 PPD whole-house dehumidifier with built-in Wi-Fi and Bluetooth, controlled through AprilAire’s Healthy Air app, for crawl spaces, basements and homes up to 5,500 sq ft. For more models, see our Whole-House & Crawl Space Dehumidifiers page.
Our Verdict
If you want to see and adjust whole-home humidity from your phone, with alerts and diagnostics, the E100W is the AprilAire to buy.
It is one of the most expensive units here, and the standard E100 costs less without the app.

Design
Top or end air discharge suits different installations, and an 8-foot power cord adds placement flexibility.
It weighs 64 pounds.
Controls
Pair it over Bluetooth in a few minutes, then connect to Wi-Fi for remote control, alerts, diagnostics and updates.
It dehumidifies until the set point is reached, then samples the air periodically to decide when to resume.
Placement Tips
In a crawl space, set the unit level on a vapor barrier, blocks or a hanger kit, away from standing water, with clear space around the intake and outlet. Run the drain hose with a steady downhill slope, or route the pump line to a sink, sump or exterior opening.
Seal vents and lay a vapor barrier first. A dehumidifier in a vented crawl space spends its effort drying outdoor air.
Running Costs and Care
Check the filter every month or two during heavy use and rinse or replace it when dirty. Make sure the drain line stays clear and, on pump models, test the pump occasionally.
Set the humidity target around 50% to 55%. The compressor then cycles off once the space is dry, which keeps running costs down.
How It Compares
Against the standard E100, the E100W adds app control for a higher price.
Against ALORAIR’s Smart Wi-Fi crawl space units, the AprilAire covers a whole home while the ALORAIR targets crawl spaces for much less money.
