Aprilaire 70 vs 50 Pint Comparison
Moisture capacity
The AprilAire 70-Pint Crawl Space Dehumidifier removes up to 70 pints of moisture per day. This higher capacity suits larger areas or more humid environments. The AprilAire 50-Pint Compact Dehumidifier handles up to 50 pints daily. You choose the 70-pint model if you need faster moisture extraction for severe dampness. The 50-pint unit is sufficient for moderate humidity levels in smaller spaces. Both units maintain balanced indoor humidity to protect woodwork and prevent mold growth.
Coverage area
Coverage area determines how much space each dehumidifier can effectively dry. The AprilAire 70-Pint Crawl Space Dehumidifier covers up to 2,200 square feet. This makes it ideal for larger basements or expansive crawl spaces. The AprilAire 50-Pint Compact Dehumidifier covers up to 1,600 square feet. It is well-suited for smaller rooms, attics, or garages. If you have a large open area, the 70-pint model provides better coverage. For smaller, confined spaces, the 50-pint unit is adequate and more compact.
Physical dimensions
Both units are designed for tight spaces, but their shapes differ. The AprilAire 70-Pint Crawl Space Dehumidifier measures 12.5 inches by 12.5 inches by 25 inches. Its square base fits well between joists. The AprilAire 50-Pint Compact Dehumidifier is smaller, measuring 10 inches by 10 inches by 25 inches. It is the smallest professional-grade option available. The 50-pint model has a lower profile, standing just 9.86 inches tall. This makes it easier to fit under low ceilings or in very cramped areas.
Weight and portability
Weight affects how easily you can move the unit during installation or maintenance. The AprilAire 70-Pint Crawl Space Dehumidifier weighs 56 pounds. It is heavier due to its larger build and corrosion-resistant aluminum coils. The AprilAire 50-Pint Compact Dehumidifier weighs 46 pounds. It includes built-in handles for convenient maneuverability. The lighter weight of the 50-pint model makes it easier to position in tight crawl spaces or attics. You will find it less strenuous to move without assistance.
Control interface
Control methods vary between the two models. The AprilAire 50-Pint Compact Dehumidifier features a built-in digital user interface. This allows you to adjust settings directly on the unit with intuitive controls. The AprilAire 70-Pint Crawl Space Dehumidifier data does not specify a built-in digital interface on the unit itself. It often pairs with wall controls or DIY bundles for operation. If you prefer direct, on-unit digital controls for quick adjustments, the 50-pint model offers this feature out of the box.

Frequently asked questions
Which AprilAire model is better for a 2,000 square foot crawl space?
The AprilAire 70-Pint Crawl Space Dehumidifier is the correct choice. It covers areas up to 2,200 square feet. The 50-Pint Compact model only handles up to 1,600 square feet. Using the smaller unit in a larger space will leave humidity levels too high. You need the higher capacity to maintain proper air quality in that environment.
Do both dehumidifiers drain automatically without a bucket?
Yes, both models support continuous drainage. They are designed to connect directly to a hose for automatic water removal. This feature eliminates the need to manually empty a water tray. You can install either unit in a hard-to-reach area like a crawl space or attic without worrying about maintenance intervals for water collection.
How much physical space does each unit require for installation?
Dimensions differ significantly between the two models. The 70-Pint unit measures 33 inches in length, 13 inches in width, and 12.9 inches in height. The 50-Pint Compact model is 9.71 inches long, 25 inches wide, and 9.86 inches high. You should measure your available clearance carefully, as the compact model is much shorter but wider.
Is the AprilAire 70-Pint unit heavy to move during installation?
The 70-Pint Crawl Space Dehumidifier weighs 56 pounds. This weight makes it heavier than the 50-Pint model, which weighs 46 pounds. You should plan for assistance when positioning the larger unit. Both units are gray and built for durability, but the extra weight of the 70-Pint model reflects its larger internal components.
Can I use the 50-Pint model in a garage?
Yes, the AprilAire 50-Pint Compact Dehumidifier is suitable for garages. It is designed for basements, crawl spaces, and garages with areas under 1,600 square feet. The 70-Pint model is also rated for basements and crawl spaces but focuses on larger square footage. Choose the 50-Pint model if your garage is on the smaller side.
What is the main difference in coverage area between these two models?
The primary difference is the maximum square footage each unit can effectively dehumidify. The 70-Pint model covers up to 2,200 square feet. The 50-Pint Compact model covers up to 1,600 square feet. If your space exceeds 1,600 square feet, the 50-Pint unit will struggle to keep humidity levels low. The 70-Pint unit provides the necessary output for larger areas.
