Aprilaire 70 vs 100 Pint Comparison

Moisture Removal Capacity

Edge: AprilAire 100-Pint Whole-House Dehumidifier

The AprilAire E100 Pro removes up to 100 pints of moisture per day, while the E070 Pro handles 70 pints daily. This difference matters if you have high humidity levels or a large volume of air to dry. The E100’s higher capacity allows it to work faster in damp conditions, reducing runtime and potentially saving energy. The E070 is sufficient for smaller spaces or moderate humidity. You should match the capacity to your actual moisture load, not just square footage. A larger capacity unit can handle sudden spikes in humidity better than a smaller one.

Coverage Area

Edge: AprilAire 100-Pint Whole-House Dehumidifier

Coverage area is a key differentiator between these two models. The E070 Pro is rated for spaces up to 2,200 square feet. The E100 Pro covers up to 5,500 square feet. If you are treating a whole house or a very large basement, the E100 is the necessary choice. The E070 is ideal for targeted areas like a crawl space or a single basement level. Using an underpowered unit in a large space will result in poor humidity control. Always check your total square footage against these ratings to ensure proper performance.

Physical Dimensions

Edge: AprilAire 70-Pint Crawl Space Dehumidifier

Size affects installation, especially in tight crawl spaces. The E070 Pro measures 12.9 inches in height and 13 inches in width. The E100 Pro is taller at 15 inches and slightly wider at 14 inches. The E070 is designed to fit between joists and through standard crawl space doors. Its compact profile makes it easier to maneuver in confined areas. The E100 is larger and heavier, which may require more careful planning for placement. If space is tight, the smaller E070 offers a distinct advantage for installation flexibility.

Energy Efficiency

Edge: AprilAire 100-Pint Whole-House Dehumidifier

The E100 Pro holds the Energy Star Most Efficient certification. This indicates it uses less energy to remove the same amount of moisture compared to standard models. The E070 Pro data does not list an Energy Star certification. For whole-house applications where the unit runs frequently, energy efficiency impacts your long-term operating costs. The E100’s efficiency rating suggests it is optimized for continuous, whole-home use. If energy consumption is a priority, the certified E100 is the better technical choice for large spaces.

Smart Sensing Technology

Edge: AprilAire 100-Pint Whole-House Dehumidifier

The E100 Pro features smart sensing technology that automatically starts dehumidification when humidity exceeds your target level. This 'set and forget' function adds convenience for whole-home management. The E070 Pro data does not explicitly mention this specific smart sensing feature in its listed attributes. While both units likely include basic controls, the E100’s automated sensing is highlighted for whole-house ease. This feature reduces the need for manual intervention, making the E100 more suitable for users who want minimal maintenance oversight.
