Aprilaire 70-Pint vs 80-Pint Comparison
Moisture capacity
The AprilAire E080 Pro handles more moisture than the E070 Pro. The E080 removes up to 80 pints of water per day. This higher capacity suits larger spaces. The E070 Pro removes up to 70 pints daily. This lower capacity fits smaller areas. You should choose based on your home size. Larger homes need the E080. Smaller homes may only need the E070. Both units use continuous drainage hoses. This means you do not need to empty a tray. The difference in capacity is significant for large basements.
Coverage area
Coverage area differs between these two models. The E080 Pro covers up to 4,400 square feet. This makes it suitable for whole-house dehumidification. The E070 Pro covers up to 2,200 square feet. This size is ideal for crawl spaces or smaller basements. You should measure your space before buying. If your area is over 2,200 square feet, the E070 may struggle. The E080 provides extra capacity for larger areas. Both units are designed for basements and crawl spaces.
Dimensions and size
Physical size affects where you can place these units. The E070 Pro is 12.5 inches wide and 12.9 inches high. It is 33 inches long. This compact size fits through most crawl space doors. It also fits between joists in tight spaces. The E080 Pro is larger at 15.4 inches wide and 17.1 inches high. It is 34 inches long. The E080 requires more floor space. You must ensure you have enough room for the E080. The E070 is better for tight crawl spaces.
Energy efficiency
Energy usage is an important factor for running costs. The E080 Pro is Energy Star Most Efficient Certified. This certification means it uses less energy for its output. The E070 Pro data does not list an Energy Star rating. You should consider this if energy bills matter to you. The E080 removes more moisture while using less energy. This efficiency helps reduce your environmental impact. Both units have corrosion-resistant aluminum coils. This feature helps them last longer in humid environments.
Weight
Weight impacts installation and moving these units. The E070 Pro weighs 56 pounds. This makes it slightly easier to move. The E080 Pro weighs 63 pounds. It is heavier due to its larger components. You should plan for installation carefully. Both units are designed for permanent or semi-permanent placement. You will likely connect them to a drain hose. Moving them after installation is not recommended. The weight difference is minor but noticeable. Consider who will install the unit.
Which Aprilaire Model Fits Your Home
Small home or tight crawl space owner
The AprilAire E070 Pro is designed for spaces up to 2,200 square feet. Its compact dimensions of 12.5 by 12.5 by 25 inches allow it to fit between joists and through standard crawl space doors. This model removes up to 70 pints of moisture daily, which is sufficient for smaller basements or confined areas where a larger unit would not fit.
Large home needing high efficiency
The AprilAire E080 Pro covers up to 4,400 square feet and removes 80 pints of moisture per day. It holds Energy Star Most Efficient certification, meaning it uses less energy to achieve its higher capacity. This model is ideal for larger whole-house applications or expansive basements where maximum moisture removal and energy savings are your primary concerns.
Installer with limited vertical clearance
If your crawl space has low ceilings, the E070 Pro is the better choice. It stands 12.5 inches tall, compared to the E080 Pro’s 17.1 inches. The smaller footprint also makes it easier to maneuver in tight spots. Both units weigh around 56 to 63 pounds, but the E070’s lower profile is easier to position in constrained crawl space environments.
Buyer wanting smart sensing features
The E080 Pro includes smart sensing technology that automatically starts dehumidification when humidity levels rise above your target setting. This set-and-forget feature simplifies operation for whole-house humidity control. While both units offer continuous drainage via hose, the E080’s advanced automation and higher capacity make it a more robust solution for maintaining consistent indoor air quality in larger homes.
