Dehumidifiers are great for combating mold and mildew in your home. However, the standard dehumidifier isn’t designed for crawl space use. A crawl space dehumidifier is specifically designed to combat excess moisture that’s common in these areas.

They help control the growth of mold and mildew while also reducing musty odors. We’ll discuss how crawl space dehumidifiers work, their benefits over other systems, and some tips on choosing one with more efficiency.

How Crawl Space Dehumidifiers Work

A crawl space dehumidifier works the same way as any other type of dehumidifier. It pulls moisture out of the air, condenses it into water, and then drains it away to be collected. The only difference is that a crawl space dehumidifier is explicitly designed for a crawl space environment. It has features that help prevent mold growth on its coils, which can clog them up and make them less effective at removing moisture from the air. 

Crawl space dehumidifiers also have special features, like an automatic shutoff switch that turns off your unit when its bucket reaches capacity. You’ll also notice that these units tend not to have wheels — they’re meant for permanent installation rather than mobility! Because these machines are designed specifically for tight spaces like under-floor spaces or basements where there isn’t much room for movement around corners or through doors (like many traditional models), having wheels would add unnecessary bulkiness without any real benefit. 

What Are the Benefits of Crawl Space Dehumidifiers?

Humid air is a breeding ground for mold and mildew, which can lead to rot and decay. It’s also the culprit behind allergies and asthma in some cases. In addition to being an eyesore, excess moisture can make your home uncomfortable. Crawl space dehumidifiers help reduce the risk of these issues by lowering humidity levels in your crawl space or basement so that you don’t have to worry about mold or mildew forming on your walls or floors.

They also extend the life of your home by preventing wood rot due to moisture buildup, which means less money spent fixing damage caused by water leaks later down the line! Plus, they’ll ensure everyone stays healthy by reducing allergy symptoms and improving overall comfort levels. They do this with added ventilation features such as fans that suck hot air out from underneath houses during summer when temperatures rise above 80 degrees outside. 

Crawl Space Dehumidifier Efficiency Ratings

The efficiency ratings on dehumidifiers are an excellent way to compare them. The higher the rating, the more water your dehumidifier can remove from the air; therefore, it will be better at removing moisture from your crawl space. 

Suppose you have two identical machines with different efficiency ratings. In that case, one will use less energy than another because it has less resistance in pulling moisture out of its surroundings since less work is involved.

Types of Crawl Space Dehumidifiers

When it comes to choosing the right dehumidifier for your basement, attic, or other crawl space, it is best to know about the different types available. There are three types of crawl space dehumidifiers, such as: 

  • Rotary: This system has a fan that rotates around a drum and blows air through it. The drum is filled with desiccants (materials that absorb water), which are then heated to release their absorbed moisture into the air. 
  • Fixed-speed: These systems use centrifugal fans or blowers to move air through an enclosed chamber, which picks up moisture from the surrounding area and deposits it out through condensation drains at the bottom of your house’s foundation walls or floor joists. Fixed-speed units tend to be more powerful than variable-speed models.
  • Desiccant: Unlike rotary or fixed-speed systems, this type of dehumidifier does not rely on refrigerant. Instead, desiccant dehumidifiers use water-absorbing canisters to lower the humidity of the crawl space, preventing mold and mildew growth.
