Coverage Capacity and Drainage Options
Moisture removal capacity
The AprilAire 70-Pint Crawl Space Dehumidifier removes up to 70 pints of moisture per day. This higher capacity allows it to handle larger spaces, covering areas up to 2,200 square feet. The AprilAire 50-Pint Dehumidifier with Pump and Wi-Fi removes up to 50 pints daily. It is rated for spaces up to 1,600 square feet. If you have a large basement or a very damp crawl space, the 70-pint model provides more aggressive drying power. The 50-pint unit is sufficient for smaller, moderately humid areas. You should match the pint rating to your square footage to avoid underperformance or unnecessary energy use.
Drainage system
Both units offer flexible drainage, but the methods differ. The AprilAire 70-Pint model relies on a standard drain hose. You can place the hose into a floor drain or connect it to your plumbing. It does not include a pump. The AprilAire 50-Pint model includes a built-in condensate pump and bracket. This pump actively pushes water away, allowing drainage to a higher point like a sump pump or sink. If your installation location lacks a gravity-fed drain nearby, the 50-pint model’s pump is a significant advantage. Otherwise, the hose-only setup of the 70-pint unit is simpler.
Physical dimensions
Size matters for tight crawl spaces. The AprilAire 70-Pint model measures 12.5 inches wide, 12.5 inches deep, and 25 inches tall. Its compact vertical design fits between joists and through standard crawl space doors. The AprilAire 50-Pint model is wider at 25 inches but much shorter at 9.86 inches tall. It is also lighter at 46 pounds compared to the 70-pint’s 56 pounds. The 50-pint unit has a low profile that may fit under low-hanging beams where the taller 70-pint unit would not. Choose based on the vertical clearance in your specific installation spot.
Smart controls and connectivity
The AprilAire 50-Pint Dehumidifier with Pump and Wi-Fi comes with a Wi-Fi IAQ thermostat and the Healthy Air App. You can control the unit remotely, set schedules, and monitor conditions from your phone. It includes a digital display on the front. The AprilAire 70-Pint Crawl Space Dehumidifier does not list Wi-Fi or app connectivity in its standard features. It relies on manual control or optional wall controls sold separately. If you want remote monitoring and automated scheduling without buying extra parts, the 50-pint model is the better choice.
Air filtration
The AprilAire 50-Pint model includes a washable MERV 8 filter. This filter cleans the air entering and leaving the unit, helping to reduce dust and allergens in your home. You can remove it for annual washing. The AprilAire 70-Pint Crawl Space Dehumidifier does not list an included air filter in its specifications. While its primary job is moisture removal, it lacks this integrated air cleaning feature. If you want dehumidification combined with basic air filtration in one step, the 50-pint unit offers added value. Otherwise, you would need a separate filtration solution for the 70-pint model.
Refrigerant type
The AprilAire 50-Pint Dehumidifier uses R32 refrigerant. This type has a low global warming potential and zero ozone depletion potential, making it more environmentally friendly. It maintains superior performance while being eco-conscious. The AprilAire 70-Pint model does not specify its refrigerant type in the provided data. While both are designed for efficient operation, the 50-pint model explicitly highlights its modern refrigerant choice. If environmental impact is a priority for your purchase, the 50-pint model’s R32 system is a clear benefit.
Which Aprilaire Model Fits Your Needs
You have a large, unsealed crawl space
The 70-Pint model covers up to 2,200 square feet. Its higher moisture removal capacity handles larger areas effectively. The compact design fits through tight crawl space doors and between joists. You can connect a drain hose for continuous operation without emptying a tray. This unit protects against mold and structural rot in bigger spaces.
You want smart home integration and automation
This model includes a Wi-Fi thermostat and the Healthy Air App. You can control humidity remotely and set schedules for weekdays or weekends. The built-in digital display lets you select desired humidity levels easily. This connectivity allows you to monitor and adjust conditions from your phone without accessing the unit directly.
You need easy drainage in a basement
The 50-Pint unit comes with a built-in condensate pump and bracket. It pumps water away to a drain or sump pump, eliminating the need for gravity drainage. This feature is ideal for basements where floor drains are not available. The low-profile design and included handles make it easy to maneuver during installation.
You prioritize maximum coverage area
With a 70-pint daily capacity, this dehumidifier handles up to 2,200 square feet. It is designed for whole-house protection in larger homes. The corrosion-resistant aluminum coils ensure durability in damp environments. If your space exceeds 1,600 square feet, this higher capacity model provides the necessary moisture removal to prevent mold and odors.

While both are relatively portable, the 50-Pint unit is easier to maneuver if you need to move it frequently.
