Alorair Crawl Space Dehumidifier Review
Choosing the Right Alorair Crawl Space Dehumidifier
Selecting the right crawl space dehumidifier involves considering several key features to ensure effective moisture removal and a healthier home environment. Here’s a breakdown of the most important factors:
PPD (Pints Per Day) and Coverage Area
The PPD rating indicates how much moisture a dehumidifier can remove in 24 hours. This is the most important factor when choosing a dehumidifier. Higher PPD ratings are essential for larger spaces or areas with significant moisture problems. Alorair offers models ranging from 70 PPD to 264 PPD.
- Smaller Crawl Spaces (under 1,000 sq ft): A 70-pint dehumidifier may suffice, especially for moderate humidity.
- Medium Crawl Spaces (1,000 – 2,300 sq ft): Models in the 120-180 pint range are generally ideal.
- Large Crawl Spaces or Flooding/Restoration (over 2,300 sq ft): Opt for the higher-capacity 264 PPD models for rapid and thorough drying.
Choosing a unit with a PPD too low for your space will result in ineffective dehumidification and potentially ongoing moisture issues. Conversely, a significantly oversized unit might cycle on and off too frequently, reducing efficiency and lifespan.
Drainage Options: Pump vs. Gravity
How the dehumidifier removes collected water is a critical consideration. Alorair dehumidifiers offer both options:
- Gravity Drainage: Requires a floor drain or a low-lying container to collect the water. This is a simple solution, but limits placement options.
- Built-in Pump: Allows the unit to pump the water upwards and over a distance, making it ideal for locations where gravity drainage isn’t possible. The pump height capacity (often around 20 feet) is an important spec to check if you need to pump water uphill. A pump adds convenience but can be slightly more prone to mechanical issues, though Alorair models are designed for durability.
Consider your crawl space layout and available drainage points. A pump provides greater flexibility, especially in challenging environments.
Smart Features & Control
Some Alorair models include Wi-Fi connectivity, enabling remote monitoring and control via a smartphone app. This feature offers several benefits:
- Remote Monitoring: Check humidity levels and operating status from anywhere.
- Adjustable Settings: Change settings without physically being in the crawl space.
- Alerts & Notifications: Receive alerts if humidity levels exceed a set threshold or if the unit requires attention.
While not essential, smart features add convenience and peace of mind, particularly if you want to maintain optimal humidity levels remotely.
Other Important Features
- Automatic Defrost: Prevents ice buildup in colder environments.
- Air Filter: Helps improve air quality by removing dust and allergens. MERV ratings indicate filter efficiency.
- Energy Star Certification: Indicates energy efficiency and lower operating costs.
- Warranty: A longer warranty provides greater protection and reflects the manufacturer’s confidence in the product. Alorair offers a 5-year limited warranty on many models.
- Physical Dimensions: Ensure the unit will physically fit within your crawl space, considering height and width restrictions.
- Noise Level: Some models operate more quietly than others. Consider this if the dehumidifier is located near living areas.

How We Tested Alorair Crawl Space Dehumidifiers
Our evaluation of Alorair crawl space dehumidifiers centers on data-driven analysis, combining published specifications with user feedback and comparative performance assessments. We prioritize verifying manufacturer claims regarding Pints Per Day (PPD) capacity and coverage area, cross-referencing these with independent tests where available. Given the challenges of standardized, independent physical testing of crawl space dehumidifiers, we heavily analyze real-world application data from verified customer reviews and professional restoration reports.
We meticulously compare models based on features detailed in the buying guide, including pump capacity, automatic defrost functionality, and smart control options. Energy efficiency, indicated by Energy Star certification, is a key metric. A significant portion of our analysis focuses on long-term reliability, evaluating warranty periods (like Alorair’s 5-year limited warranty) and reported failure rates across different models. We also assess user reports on noise levels and ease of maintenance, recognizing the practical considerations of operating a dehumidifier in a confined crawl space environment. Finally, we leverage moisture removal data to understand how different Alorair units perform in varying humidity and temperature conditions.
FAQs
What PPD (Pints Per Day) Alorair dehumidifier do I need?
The ideal PPD for your Alorair crawl space dehumidifier depends on your crawl space size and moisture level. Use this as a guide: under 1,000 sq ft (70 PPD), 1,000-2,300 sq ft (120-180 PPD), over 2,300 sq ft (264 PPD). Choosing the right PPD ensures effective moisture removal in your crawl space.
What’s the difference between a dehumidifier with a pump and gravity drainage?
Gravity drainage requires a floor drain or container, limiting placement. A built-in pump allows the Alorair dehumidifier to pump water upwards, offering flexibility, especially when a drain isn’t readily available.
Are Alorair dehumidifiers Energy Star certified?
Some Alorair models are Energy Star certified, meaning they meet strict energy efficiency guidelines. Look for this certification to lower operating costs and minimize your environmental impact.
