The Dry Pro 70 Dehumidifier is a professional-grade crawl space dehumidifier designed to control excess moisture and humidity in encapsulated crawl spaces, basements, and other moisture-prone areas.

At Crawl Space Ninja Supply, we know choosing a dehumidifier is about more than the square footage printed on the box. Your crawl space layout, encapsulation, airflow, moisture conditions, and desired humidity level all play a role in choosing the right unit.

The Dry Pro 70 is recommended for crawl spaces up to 2,200 square feet under our 45–50% RH sizing recommendations, making it a strong choice for many residential crawl space encapsulation projects.

A crawl space dehumidifier is one part of a complete moisture-control system. A properly installed crawl space vapor barrier, sealed foundation walls, closed vents, proper drainage, mold remediation when necessary, and the right dehumidifier work together to help maintain a dry, controlled crawl space.

If you're shopping for crawl space encapsulation supplies, encapsulation materials, or a dehumidifier for your crawl space, the Ninja Dry Pro 70 is designed to be an important part of that complete system.

The goal isn't just to make your crawl space look dry. It's to keep it dry.

Need a Condensate Pump?

The Dry Pro 70 uses continuous drainage, but depending on your installation, gravity may not be enough to get the condensate where it needs to go. A condensate pump can move the water to a higher drain point when necessary.

Recommended options:

• Automatic Condensate Pump for Dehumidifiers and HVAC Systems: A straightforward solution for moving dehumidifier condensate when gravity drainage isn't possible.

• DiversiTech® PROCP-22S Condensate Pump — 22-Foot Lift, 120V Provides up to 22 feet of lift for installations requiring additional drainage height.

Frequently Asked Questions

What size crawl space does the Ninja Dry Pro 70 cover?

The Crawl Space Ninja® Dry Pro 70 is recommended for crawl spaces up to 2,200 square feet when maintaining our recommended 45–50% relative humidity range. Actual performance can vary based on crawl space layout, airflow, encapsulation, temperature, and moisture conditions.

Do I need a vapor barrier if I have a crawl space dehumidifier?

Yes, in most encapsulation projects. A dehumidifier controls humidity in the air, while a properly installed crawl space vapor barrier helps reduce moisture entering from the ground. They address different parts of the moisture-control problem and work best together.

Is the Ninja Dry Pro 70 a good alternative to the AprilAire E070?

Yes. We love AprilAire, and the E070 is an excellent professional crawl space dehumidifier. However, we don't control AprilAire's pricing, and we saw homeowners putting off or skipping a dehumidifier because of the cost.

That's one reason we developed the Ninja Dry Pro 70 as a professional-grade, cost-effective alternative with specifications designed to closely mirror the E070 where it matters for crawl space humidity control.

If Wi-Fi control and remote monitoring are important to you, the AprilAire E070 is a great option. If you don't need Wi-Fi, the Ninja Dry Pro 70 gives you professional crawl space humidity control without paying for a feature you may not use.

Should I install the vapor barrier before the dehumidifier?

The dehumidifier can be used before the vapor barrier is installed. After mold has been properly remediated and the affected surfaces have been cleaned, running the dehumidifier can help dry the crawl space and bring humidity under control before the vapor barrier is installed.

Once the encapsulation is completed, the vapor barrier and dehumidifier work together to maintain a controlled crawl space environment.

What's the difference between the Ninja Dry Pro 70 and a $400 dehumidifier?

The biggest difference isn't always what the unit looks like it's what's behind it. When comparing a lower-cost dehumidifier with a professional crawl space dehumidifier, look at its intended operating conditions, actual capacity, warranty, serviceability, replacement parts, and long-term support.

At Crawl Space Ninja Supply, we view a dehumidifier as a long-term investment in moisture control, not something you should expect to replace every couple of years.
