Buying Guide: Crawlspace dehumidifiers

Moisture Removal Capacity

Consider the dehumidifier’s pint-per-day rating. Choose a unit that can handle your space’s moisture levels, typically ranging from 70 to 198 pints per day for crawlspaces.

Coverage Area

Match the dehumidifier’s capacity to your crawlspace size. Models range from 1,000 to 5,000 square feet coverage, ensuring efficient moisture control throughout the space.

Energy Efficiency

Look for Energy Star certified models. These units offer superior energy efficiency, reducing operating costs while maintaining effective dehumidification performance.

Drainage Options

Consider units with built-in pumps or gravity drainage. Pump-equipped models offer more flexibility, allowing water removal even when a floor drain isn’t available.

Durability and Maintenance

Opt for dehumidifiers with corrosion-resistant components and auto-defrost features. These ensure longevity and reduce maintenance needs in challenging crawlspace environments.

FAQs: Crawlspace dehumidifiers

What size dehumidifier do I need for my crawlspace?

Choose a dehumidifier based on your crawlspace’s square footage and moisture levels. For most homes, a 70-pint unit is sufficient, while larger or very damp spaces may require 90-pint or higher capacity models.

How often should I run my crawlspace dehumidifier?

For optimal moisture control, run your crawlspace dehumidifier continuously. Most modern units have built-in humidistats that automatically maintain desired humidity levels, typically between 30-50%.

Can I use a regular dehumidifier in my crawlspace?

While possible, it’s not recommended. Crawlspace dehumidifiers are designed to operate in cooler temperatures and have features like pump drainage and corrosion resistance that standard models may lack.

How do I maintain my crawlspace dehumidifier?

Regular maintenance includes cleaning or replacing the air filter, checking and cleaning the condensate drain, and ensuring proper airflow around the unit. Follow the manufacturer’s guidelines for specific maintenance tasks and frequency.

Will a crawlspace dehumidifier help with mold issues?

Yes, by reducing humidity levels, a crawlspace dehumidifier can help prevent mold growth. However, existing mold should be professionally removed before installing a dehumidifier to prevent further spread.

Are crawlspace dehumidifiers noisy?

Most modern crawlspace dehumidifiers are designed to operate quietly. However, noise levels can vary between models, so check decibel ratings if noise is a concern.

How long do crawlspace dehumidifiers typically last?

With proper maintenance, a quality crawlspace dehumidifier can last 5-10 years. Many manufacturers offer 5-year warranties, indicating their expected lifespan under normal use.

Final Verdict: Crawlspace dehumidifiers

For small to medium crawlspaces, the BaseAire or ARGENDON models offer efficient moisture control. Those with larger areas or commercial needs should consider the high-capacity ALORAIR or Waykar units for optimal performance.
