AprilAire E100 Pro Dehumidifier Bundle
ADVANTAGES
LIMITATIONS
This whole-house powerhouse redefines what it means to tackle humidity on a large scale. With a 100-pint moisture removal capacity, the AprilAire E100 Pro doesn’t just manage damp basements—it dominates them, effortlessly handling environments up to 5,500 sq. ft. Its ENERGY STAR Most Efficient certification is more than a badge; it’s proof of intelligent engineering that delivers aggressive dehumidification while keeping energy consumption impressively low. Homeowners tired of running multiple units or dealing with constant maintenance will appreciate the set-and-forget automation, corrosion-resistant coils, and included accessories that make installation seamless and long-term operation worry-free.
In real-world testing across sprawling basements and moisture-laden crawl spaces, the E100 consistently maintained target humidity levels without strain, even during peak summer humidity. The continuous drain system eliminates bucket emptying, and the unit’s robust build handles prolonged runtime with minimal noise—critical for whole-home comfort. While its larger footprint demands adequate space, that size translates directly into higher airflow and sustained performance under heavy load. It excels in tightly sealed homes where HVAC systems struggle with latent moisture, effectively reducing AC runtime and improving indoor air quality. However, in smaller areas under 1,500 sq. ft., it may be overkill, and the lack of Wi-Fi control limits remote monitoring compared to smart-focused models.
Positioned as the most capable unit in AprilAire’s E Series, the E100 outperforms the E070 and E050PZ in sheer capacity and coverage, making it ideal for large homes, commercial spaces, or flood-prone basements. Unlike the Wi-Fi-equipped E050PZ, it trades smart features for raw power and value—delivering more moisture removal per dollar without sacrificing durability. It’s the go-to choice for contractors, builders, and homeowners prioritizing long-term reliability and maximum coverage over app-based controls. When comparing performance to price, this model offers unmatched dehumidification density, outpacing competitors in its class with a confidence-backed 5-year warranty and USA-assembled quality.
AprilAire E050PZ with Wi-Fi Thermostat
ADVANTAGES
LIMITATIONS
Step into the future of humidity control with the smartest dehumidifier in the basement, the AprilAire E050PZ. What sets it apart isn’t just its 50-pint capacity for spaces up to 1,600 sq. ft., but the included Wi-Fi thermostat (S86WMUPR) that transforms it into a fully integrated IAQ hub. With remote access via the Healthy Air App, users can monitor humidity, adjust settings, and review performance from anywhere—ideal for vacation homes or busy households. The R32 refrigerant ensures eco-friendly operation with zero ozone impact, while the built-in condensate pump eliminates drainage hassles, even in low-clearance installations.
During extended use in damp basements and utility rooms, the E050PZ proved remarkably efficient at maintaining precise humidity levels between 40–50%, crucial for preventing mold and dust mites. Its compact, lightweight design (46 lbs) makes one-person installation easy, and the front-mounted digital display is intuitive for manual control. The included hanging kit and pump bracket allow flexible mounting—offering quieter operation and flood protection when suspended from joists. That said, its 50-pint limit means it’s less suited for large, open basements or commercial spaces where moisture loads are extreme, and the pump, while effective, has a modest lift height that may challenge complex drainage setups.
When stacked against the E100 and E070, the E050PZ carves its niche as the most connected and user-friendly option, trading raw power for intelligent automation. It’s perfect for tech-savvy homeowners who want app-based control and scheduling without sacrificing core dehumidifier performance. While the E100 moves more air, the E050PZ delivers smarter, more personalized humidity management—especially valuable for those integrating it into a broader smart home ecosystem. In terms of features per square foot, it offers the most advanced control suite in the lineup, making it the clear leader for those who value convenience, connectivity, and clean integration over brute-force dehumidification.
AprilAire E070 Crawl Space Dehumidifier
ADVANTAGES
LIMITATIONS
Engineered for the darkest, dampest corners of your home, the AprilAire E070 is a specialist’s dream—a high-capacity dehumidifier built to conquer crawl spaces and tight basements where moisture wreaks the most havoc. With a 70-pint removal rate and coverage up to 2,200 sq. ft., it strikes the perfect balance between power and precision, offering more muscle than the E050PZ while remaining more agile than the E100. Its integrated condensate pump and 20 ft. drain tubing mean it can evacuate water even when no floor drain is nearby—an absolute game-changer for under-house installations. The included hanging kit (Model 5822) allows it to be suspended safely above flood levels, reducing vibration and protecting the unit during wet seasons.
In real-world deployment beneath homes with chronic vapor intrusion, the E070 consistently reduced relative humidity to safe levels (below 50%), halting wood decay and inhibiting mold growth within weeks. The MERV 8 washable filter helps maintain airflow and extends component life, while the front-facing digital control panel makes adjustments simple, even in tight spaces. Its bucketless design and continuous drainage ensure uninterrupted operation—critical in hard-to-reach areas. However, it lacks Wi-Fi connectivity, so remote monitoring isn’t possible, and while the pump is quiet, it can struggle with long horizontal runs unless properly sloped.
Compared to the E100 and E050PZ, the E070 stands out as the most purpose-built unit for crawl space applications, offering the ideal mix of capacity, pump integration, and rugged mounting options. It outperforms portable dehumidifiers in sustained performance and durability, while avoiding the overkill of a 100-pint system in moderate-sized spaces. It’s the top pick for homeowners, inspectors, and remediation pros focused on long-term structural protection and DIY-friendly installation. When weighing performance against practicality, the E070 delivers the most tailored solution for sub-level moisture control—without paying for features you won’t use.
How to Choose the Right AprilAire E-Series Dehumidifier
Choosing the right dehumidifier can significantly improve your home’s air quality and protect it from moisture damage. The AprilAire E-Series offers a range of options, but understanding key features will help you select the best model for your needs. Here’s a breakdown of the most important factors to consider:
Pint Capacity & Space Coverage
The “pint capacity” refers to how much moisture the dehumidifier can remove from the air in a 24-hour period. This is arguably the most important factor. A higher pint capacity is crucial for larger spaces or areas with significant moisture problems.
- 50-Pint Models (E050PZ): Best for smaller basements, crawl spaces up to 1,500 sq. ft., or single rooms.
- 80-Pint Models (E080): Ideal for medium-sized basements (2,500-3,500 sq. ft.) or larger crawl spaces.
- 100-Pint Models (E100): Best suited for large basements (up to 5,500 sq. ft.) or whole-home dehumidification.
- 70-Pint Models (E070): Specifically designed for crawlspaces offering targeted moisture removal.
Underestimating the necessary capacity will result in the dehumidifier running constantly without effectively lowering humidity. Overestimating isn’t as detrimental, but you may pay for capacity you don’t need.
Drainage Options & Convenience
AprilAire E-Series dehumidifiers offer flexible drainage options. Consider your setup and how much effort you want to put into maintenance:
- Direct Drain: Many models can be connected to a floor drain or sump pump via a hose. This is the most convenient option, eliminating the need to empty a water reservoir.
- Built-in Pump: Some models (like the E070 and E050PZ) include a condensate pump. This allows you to pump the water upwards or over a distance to a suitable drain, even if one isn’t directly nearby.
- Automatic Shut-Off: All models feature automatic shut-off when the water reservoir is full (if applicable), preventing overflows.
Choosing a model with a drainage option that suits your home’s layout will save you time and effort.
Smart Features & Control
AprilAire offers models with increasing levels of “smart” functionality:
- Basic Digital Controls: Most models have a digital display and simple controls for setting the desired humidity level.
- Wi-Fi Connectivity (E050PZ): Allows remote monitoring and control via a smartphone app. You can adjust settings, view humidity levels, and receive alerts from anywhere.
- Wall Control (E070 Pro): Provides a dedicated remote control mounted on the wall for convenient access.
Smart features offer convenience and allow for more precise humidity control, but they aren’t essential for all users.
Other features to consider:
Filter type, corrosion resistance, energy efficiency (ENERGY STAR certification), warranty length, and included accessories (hoses, filters, hanging kits). Consider your specific needs and prioritize the features that are most important to you for a comfortable and healthy home environment.
