What Is A Crawl Space Dehumidifier?

A crawl space dehumidifier is a specifically designed device to remove excess moisture from the air in your crawl space. Crawl spaces are often prone to high moisture levels, which can cause serious health problems for you and your family.

A crawl space dehumidifier will help to keep your crawl space dry and free of mold and mildew.

A commercial dehumidifier is an excellent option for particularly damp crawl spaces. These units are designed to remove large amounts of moisture from the air, and they can be set to run continuously until the space is dry.

How do Dehumidifiers work?

Dehumidifiers draw in moist air and pass it over a cooling coil. As the air passes over the coil, the water in the air condenses and is collected in a tray or reservoir. The dry, cooled air is then passed back into the room while the water is drained away or evaporated.

The amount of water that a dehumidifier can remove from the air depends on the model and the size of the unit. AlorAir dehumidifiers vary in power, but some can remove up to 70 pints of water per day!

What Are The Benefits Of Using A Crawl Space Dehumidifier?

There are many benefits to using a crawl space dehumidifier, including:

Reduced mold growth:

Mold loves damp, dark, and humid environments often found in crawl spaces. Using a dehumidifier, you can create a drier environment that is less conducive to mold growth.

Preventing wood rot:

Wood rot is another common problem in damp crawl spaces. It can cause your floor joists and support beams to weaken and eventually collapse. A dehumidifier can prevent wood rot and keep your crawl space in good condition.

Eliminating musty odors:

Most crawl spaces have a musty smell due to the high moisture levels. The smell is often the first sign that there is a problem with excess moisture. A dehumidifier will help to eliminate musty odors, leaving your crawl space smelling fresh and clean.

Preventing health problems:

Excess moisture in the home can cause several health problems, such as respiratory problems, allergies, and asthma. Here, a crawl space dehumidifier can create a healthier environment for you and your family.

Reducing energy costs:

Heating and cooling a damp, humid crawl space can be expensive. Maintaining a dry space will help reduce energy costs and make your home more comfortable.

Expert Advice: Maintaining Your Dehumidifier

To ensure the longevity and optimal performance of your dehumidifier, follow these practical suggestions:

  • Regularly clean or replace the filter every 6 to 12 months, depending on the manufacturer's recommendation.

  • Keep the dehumidifier in a well-ventilated area to allow for proper air circulation.

  • Periodically check for any signs of damage or wear and tear on the unit, and address any issues promptly.

  • Schedule a professional maintenance check if you notice any unusual noises or decreased performance from your dehumidifier.
