Professional Crawl Space Humidity Control

The Aprilaire E070 Crawl Space Dehumidifier is one of our most popular solutions for controlling humidity in encapsulated crawl spaces, basements, and other below-grade areas.

Its compact design fits where many larger dehumidifiers can't while still removing up to 70 pints of moisture per day. The E070 helps reduce excess humidity, discourage mold growth, protect wood framing, and improve your home's indoor air quality.

At Crawl Space Ninja Supply, our DIY Specialist, AJ Howard, typically recommends the Aprilaire E070 for encapsulated crawl spaces up to 2,200 square feet while targeting a healthy humidity range of 45-50% RH. If your crawl space has multiple sections, additions, or an unusual layout, AJ can help you choose the right dehumidifier before you buy.

Available in Wi-Fi

The Aprilaire E070W includes built-in Wi-Fi, allowing you to monitor humidity, adjust settings, and receive alerts directly from your smartphone using the Aprilaire Healthy Air App.

Not Sure Which Crawl Space Dehumidifier You Need?

Choosing a crawl space dehumidifier isn't just about square footage. Crawl space layout, encapsulation, airflow, and your desired humidity level can all affect which dehumidifier is right for your home.

AJ Howard, DIY Specialist at Crawl Space Ninja Supply, created our complete crawl space dehumidifier sizing guide to help homeowners compare models and understand how we recommend sizing dehumidifiers for 45–50% relative humidity (RH).

FAQ:

How loud is the Aprilaire E070?

The Aprilaire E070 operates at approximately 53 dBA when ducted, this falls within the 46–65 dB range, which is typical for everyday environments such as quiet offices libraries, or residential streets 

What size crawl space will the Aprilaire E070 cover?

At Crawl Space Ninja Supply, our DIY Specialist, AJ Howard, typically recommends the Aprilaire E070 for encapsulated crawl spaces up to approximately 2,200 square feet while targeting a healthy humidity range of 45-50% RH. Coverage can vary depending on your climate, moisture load, crawl space layout, and whether the space is fully encapsulated.

How often should I clean or replace the MERV 8 filter?

We recommend inspecting and cleaning the washable MERV 8 filter every 6 months. Depending on your crawl space conditions, the filter should typically be replaced every 6-12 months to maintain proper airflow and performance. The cool thing about these filters is that they are washable! 

Does the Aprilaire E070 need a condensate pump?

Not always. If your dehumidifier can drain by gravity or near a watermanagment system, a condensate pump isn't necessary. If the drain location is above the dehumidifier or gravity drainage isn't possible, we recommend adding the Aprilaire 4856 Low Profile Condensate Pump.

How much electricity does the Aprilaire E070 use?

The Aprilaire E070 operates on 120 volts, draws approximately 5.2 amps, and plugs into a standard 120V household outlet. It's also ENERGY STAR Certified, making it an efficient choice for controlling humidity year round. Actual energy usage will vary depending on your crawl space conditions and how often the dehumidifier runs.

How long should an Aprilaire dehumidifier last?

In a properly encapsulated crawl space with routine maintenance, you can typically expect an Aprilaire dehumidifier to last 10-15 years. Keeping the filter clean and maintaining a sealed crawl space helps maximize its lifespan. If the crawl space isn't fully encapsulated or the unit is constantly battling outside humidity, its lifespan can vary depending on the environment and operating conditions.

Where should I install the Aprilaire E070?

At Crawl Space Ninja, we install the Aprilaire E070 as close to the center of the crawl space as possible. A central location allows the dehumidifier to circulate air more evenly throughout the space for better humidity control. If your crawl space has multiple sections, additions, or separated areas, additional ducting or a different installation strategy may be recommended.

Can the Aprilaire E070 sit directly on the crawl space floor?

Yes. The Aprilaire E070 is designed to sit upright and level on its adjustable feet. If you'd like to elevate the unit, Aprilaire Risers or standard cinder blocks are both commonly used to keep the dehumidifier off the crawl space floor while maintaining proper operation.

How much clearance does the Aprilaire E070 need?

Aprilaire recommends maintaining at least 12 inches of clearance in front of the air inlet and 36 inches of clearance in front of the air discharge. This allows the dehumidifier to move air efficiently and helps ensure optimal performance.

Can I duct only one side of the Aprilaire E070?

Yes. Depending on your application, the Aprilaire E070 can be installed with one side ducted or both sides ducted. However, for the best airflow and humidity control, we typically recommend following Aprilaire's installation guidelines and ducting the unit as needed for your specific crawl space layout.

Can I use flexible ducting with the Aprilaire E070?

Yes. Flexible insulated ducting is commonly used with the Aprilaire E070. To maintain proper airflow, keep duct runs as short and straight as possible while avoiding unnecessary bends or sharp turns that can restrict airflow.
