AprilAire E070 70 Pint Crawl Space Dehumidifier

AprilAire E070 70 Pint Crawl Space Dehumidifier

The AprilAire E070 70 Pint Crawl Space Dehumidifier is a professional-grade humidity control system designed for sealed crawl spaces and stand-alone moisture control applications. It removes up to 70 pints of moisture per day at 80°F and 60% RH, helping protect the home from mold, mildew, musty odors, pests, and moisture-related structural damage.

The E070 uses a sealed R32 refrigeration system to cool incoming air below its dew point, remove moisture through continuous drainage, then reheat and return drier air back into the space. Its compact cabinet, washable MERV 8 filter, built-in digital controls, and plug-in power cord make it a strong choice for professional crawl space encapsulation and basement humidity control projects.

In simple terms: This dehumidifier keeps crawl spaces and basements dry by automatically removing excess moisture and draining it away continuously.

Why Crawl Space Humidity Matters

Up to half of the air you breathe on the first floor can come up from the crawl space below. When that space stays damp (above about 60% relative humidity), it creates the perfect conditions for mold, mildew, wood rot, dust mites, and pests like termites and cockroaches. Damp air also makes insulation sag, floors cup, and your HVAC system work harder.

Sealing or encapsulating a crawl space with a vapor barrier is only half the job. Moisture still enters through the ground, foundation walls, and air leaks. A dedicated crawl space dehumidifier like the E070 holds the space at a steady, safe humidity level all year, so the encapsulation actually does its job.

Why Choose the AprilAire E070

• Built for crawl spaces, not living rooms: Unlike portable bucket dehumidifiers, the E070 is a sealed, commercial-style unit made to run in tight, dirty, humid spaces for years.
• Small enough to fit through tight access: At 12.5" x 12.5" x 25" it fits through most crawl space openings and between floor joists.
• Set it and forget it: No bucket to empty. Water drains away continuously through the included 10 ft hose or an optional condensate pump.
• Runs only when needed: Smart air sampling checks humidity every hour and only runs the compressor when the space is too damp, which saves energy.
• Made by AprilAire: AprilAire has built whole-home indoor air quality products in Madison, Wisconsin for decades and is a trusted name with HVAC and crawl space contractors.
• Backed by a 5-year warranty: Defective parts are replaced free by AprilAire for five years from installation.

Is the E070 the Right Size?

Sealed crawl space up to ~2,200 sq. ft.	E070 is a good fit
Basement or very wet crawl space	E070 works for smaller spaces; consider the 100-pint E100 for larger or wetter areas
Whole house / ducted to HVAC	Choose the AprilAire E100 (E070 must not be ducted into HVAC)
