A Smarter System

Pairing the AprilAire Water Sensor (ZAZW) with the AprilAire E070W Wi-Fi Dehumidifier gives homeowners a complete crawl space moisture protection solution. The E070W controls excess humidity to help prevent mold, odors, and structural damage, while the water sensor detects leaks and standing water early. Together, they provide smarter moisture management, real-time monitoring, and added protection for healthier indoor air and long-term home preservation.

Not Sure Which Dehumidifier Is Right for You?

Choosing a crawl space dehumidifier can feel overwhelming, but it doesn’t have to be. The right unit depends on more than just square footage or pint capacity. Crawl space conditions, height and layout, drainage, airflow, and the features you want can all help determine which model is the best fit.

Our Crawl Space Dehumidifier Buying Guide walks you through these factors step by step, explains the differences between the models we carry, and helps you narrow down your options so you can choose the right dehumidifier for your crawl space with confidence.
