By researching and selecting the best dehumidifiers for crawl space under house, you can ensure that you’re getting the right model for your needs.
How Dehumidifiers Work in a Crawl Space
Dehumidifiers work by drawing in moist air and passing it over a cold coil. This causes the moisture in the air to condense into water, which is then collected in a reservoir or drained away. The dry air is then blown back into the crawl space, reducing the humidity levels.
There are two main types of dehumidifiers: refrigerant and desiccant. Refrigerant dehumidifiers use a refrigerant to cool the air and condense the moisture. They are generally more efficient than desiccant dehumidifiers, but they can be more expensive. Desiccant dehumidifiers use a material called a desiccant to absorb moisture from the air. They are less efficient than refrigerant dehumidifiers, but they can operate in colder temperatures.
When choosing a dehumidifier for your crawl space, it’s important to consider the size of the space, the humidity levels, and your budget. A larger dehumidifier will be more effective at removing moisture from a larger space, but it will also be more expensive. A smaller dehumidifier may be sufficient for a smaller space, but it may not be able to remove all of the moisture.
Maintaining a Healthy Crawl Space
A healthy crawl space is essential for a healthy home. It helps prevent mold growth, wood rot, and other moisture-related problems. Dehumidifiers are an important part of maintaining a healthy crawl space. They help to remove excess moisture, which can create a hospitable environment for mold and mildew.
In addition to using a dehumidifier, there are other steps you can take to maintain a healthy crawl space. These include:

Best Dehumidifiers for Crawl Space Under House: A Buyer’s Guide
A damp crawl space can lead to a myriad of problems, including mold growth, wood rot, and unpleasant odors. A dehumidifier is an essential tool to combat moisture in your crawl space, creating a healthier and safer environment for your home. However, with so many options available, choosing the right dehumidifier for your crawl space can be a daunting task. This comprehensive guide will walk you through the seven key factors to consider when making your purchase.
1. Capacity (Pints per Day)
The first and foremost consideration is the capacity of the dehumidifier, measured in pints per day. This figure indicates the amount of moisture the unit can remove from the air within a 24-hour period. Determining the right capacity is crucial for effective dehumidification.
To accurately gauge the necessary capacity, you need to determine the cubic footage of your crawl space. You can calculate this by multiplying the length, width, and height of the space.

Remember, selecting a dehumidifier with a capacity too small for your crawl space will be ineffective, while an oversized unit can be unnecessarily expensive and consume more energy.
2. Drainage Options
Effective drainage is vital for a dehumidifier operating in a crawl space. Dehumidifiers collect moisture in a built-in tank, and if not emptied regularly, it can overflow and cause damage. The drainage options offered by different dehumidifiers play a crucial role in convenient and hassle-free operation.
There are two main drainage options: manual emptying and continuous drainage. Manual emptying requires you to regularly remove the collected water from the tank. Continuous drainage, on the other hand, allows the dehumidifier to continuously drain water into a nearby drain or outlet. Consider your access to the crawl space and your preferred level of maintenance when deciding which drainage method suits you best.
3. Energy Efficiency
Since dehumidifiers will be running continuously, energy efficiency is an important consideration for the best dehumidifiers for crawl space under house. Look for models with Energy Star ratings, as these are certified to be energy-efficient.
Energy efficiency is also related to the dehumidifier’s capacity. While a large-capacity dehumidifier might seem like the obvious choice, it may use more energy than necessary. Choose a unit with a capacity that is just right for your crawl space, and you’ll be able to lower your energy consumption and operating costs.
4. Humidity Control Features
Dehumidifiers come with various humidity control features that allow you to customize the moisture level in your crawl space. Some models offer basic controls with fixed humidity settings, while others provide more advanced options like automatic humidity control with programmable settings.
