Recommended Applications

The AprilAire E100 is designed for crawl spaces, basements, and other suitable areas where excess humidity needs to be controlled. AprilAire advertises coverage up to 5,500 square feet, but actual sizing depends on your location, crawl space construction, sealing, moisture load, and target humidity.

At Crawl Space Ninja, we recommend sizing dehumidifiers according to the humidity level you're trying to maintain, not square footage alone. For a target of 45–50% relative humidity (RH), consider your crawl space's conditions and the appropriate sizing guidance before selecting a unit.

Frequently Asked Questions

What is included in the AprilAire E100 Dehumidifier Bundle?

The bundle includes one AprilAire E100 or E100W dehumidifier and one set of four AprilAire risers. 

What is the difference between the bundled and non-bundled AprilAire E100?

The standalone AprilAire E100 and E100W dehumidifiers are sold individually, while this bundle pairs your selected dehumidifier with a set of four genuine AprilAire risers. You get 6-inch risers to suit your installation. If you already have risers or don't need them, the standalone dehumidifier may be the better option.

What is the difference between the AprilAire E100 and E100W?

Both models provide up to 100 pints of moisture removal per day under rated test conditions. The E100 uses built-in digital controls, while the E100W adds built-in Wi-Fi connectivity for remote monitoring, adjustments, alerts, diagnostics, and updates through the AprilAire Healthy Air app.

How much square footage can the AprilAire E100 cover?

AprilAire advertises the E100 for areas up to 5,500 square feet. However, recommended coverage depends on the crawl space's region, sealing, moisture conditions, and desired humidity level. At Crawl Space Ninja, we recommend sizing for your target of 45–50% relative humidity (RH), in this instance it covers up to 3,300 sqft rather than relying on square footage alone.

Why elevate a crawl space dehumidifier?

Risers raise the dehumidifier above the installation surface, providing clearance beneath the unit and helping accommodate a suitable condensate drainage arrangement. The unit should remain level and securely supported.

Does this bundle include a condensate pump?

No. This bundle includes the dehumidifier and risers only. A condensate pump may be needed when gravity drainage is not practical or the discharge point is above the dehumidifier. Pump selection depends on your installation.

Is the AprilAire E100 suitable for an encapsulated crawl space?

Yes. The E100 is designed for dehumidification applications that include properly sealed crawl spaces. Correct sizing, appropriate drainage, adequate airflow, and effective moisture management all contribute to performance.

Does the AprilAire E100 come with a warranty?

Yes! A 6 year warranty guranteed!

Can I use the Wi-Fi model without a smartphone?

The E100W retains its onboard controls. Wi-Fi provides additional remote monitoring and adjustment features through the compatible AprilAire Healthy Air app.

Can I use a discount code with this bundle?

This bundle is offered at special package pricing, so additional discount codes and promotional offers cannot be applied to this purchase.
