The Aprilaire E100 is one of the most capable, reliable, and energy-efficient 100-pint commercial dehumidifiers in the industry — built for crawlspaces, basements, commercial facilities, restoration environments, and any setting that demands powerful year-round humidity control.

Engineered with Aprilaire’s signature durability and commercial-grade components, the E100 removes 100 pints of water per day while maintaining the highest Energy Star performance rating in its class. Whether it’s preventing mold, protecting stored inventory, managing moisture in large residential homes, or controlling humidity in commercial spaces, the E100 delivers long-term, worry-free operation.

A Commercial-Grade Workhorse With Residential-Level Efficiency

Unlike standard big-box dehumidifiers, the Aprilaire E100 is designed for continuous, 24/7 operation with a heavy-duty aluminum coil, high-capacity centrifugal blower, and reinforced steel cabinet. Its Energy Star rating ensures that despite its high performance, operating costs remain exceptionally low — especially important for clients running units year-round in demanding environments.

The E100’s efficiency is so strong that it regularly qualifies for local energy rebates depending on the customer’s state and utility provider.

Large Space Coverage — Up to 5,500 Sq Ft

The E100 is ideal for:

• Multi-room humidity control
• Whole-home moisture removal
• Crawlspaces & basements
• Commercial offices
• Warehouses
• Gyms & fitness centers
• Schools
• Light industrial spaces
• Data rooms
• Workshops & storage areas

This wide coverage makes it one of the most versatile dehumidifiers on the market, with proven performance in both residential and commercial applications.

Precision Control & Automation

A built-in smart digital control panel allows the user to:

• Set exact humidity levels
• Monitor system status
• View error notifications
• Adjust settings for changing environments

Once set, the E100 automatically maintains the target humidity with no further adjustments needed. Aprilaire’s onboard logic system continuously monitors humidity, temperature, and system load, ensuring consistent performance.

Multiple Installation Options

The E100 is designed with maximum flexibility:

• Freestanding installation
• Suspended from floor joists
• Integrated into HVAC return
• Ducted to multiple rooms
• Crawlspace or basement placement
• Optional fresh-air ventilation

Contractors love the Aprilaire units because they install cleanly, quickly, and with minimal callbacks.

Built for Harsh Environments

Humidity issues often occur in the most unforgiving places — crawlspaces, unconditioned basements, cold mechanical rooms, and environments exposed to temperature swings.

The Aprilaire E100 handles these with ease.
Operating range: 41°F – 104°F
This makes it highly effective in the Midwest, Southeast, coastal states, and humid climates year-round.

• High capacity without commercial-size weight
