Not only does it pose a threat to the structural integrity of the house, but it can be harmful to the people living in it. This is why adding a dehumidifier to a crawl space is ideal, as it keeps the air clean and the house damage-free.
For this purpose, we have put together a comprehensive guide that will help you find the best crawl space dehumidifier. We hope this list allows you to purchase the most suitable products that can keep your family safe.
Without further ado, let’s get right to it!

Buying Guide For The Best Crawl Space Dehumidifier
Although we are done reviewing some of the top brands for dehumidifiers, we are far from finished. The issue with excess moisture is not a new one, and hence most crawl space dehumidifiers are well-equipped to control humidity levels. However, the main question is - which one is ideal for you?
To simplify this, we have put together a short buyer’s guide to list out some of the top factors to consider when buying such a product. Let’s get into it in a bit more detail, shall we?
1. Size And Coverage
One of the first things to look into is the dehumidifier’s size and coverage area. Make sure you know the house’s square footage and the size of the dehumidifier to ensure it is suitable. Furthermore, most of these products mention pretty clearly the kind of space they can be used in.
Another thing to keep in mind is the pints per day amount of the product, ensuring it can extract moisture from the entire space.
2. Noise Levels
Conduct ample research on the product to ensure it does not make noise as it does its job. Not only that, it is always better to have a crawl space dehumidifier that can operate silently from start to finish. Since many of these are kept in basements and crawl spaces near bedrooms, a quiet dehumidifier will ensure no one is disturbed.
3. Humidistat
The role of a dehumidifier is to reduce and maintain humidity levels. Hence, the humidistat is the essential feature of the product. Moreover, a programmable humidistat ensures that the entire product can be controlled without manually operating the product.
The only thing to ensure is that the humidistat does not use up too much energy (as it tends to do).
4. Drainage
Most crawl spaces are quite dark, dingy, and challenging to be in for a long time. Having a crawl space dehumidifier in such areas will ensure humidity removal and drainage of any collected water without any manual help. This is why it is crucial to ensure that the dehumidifier comes with a drain hose and a convenient system for automatic drainage.
5. Additional Features
There are excellent features in many units these days, such as auto-defrost, memory reset, and remote usage. All of these ensure the product is user-friendly and easy to maintain despite challenging circumstances.
Crawl spaces are susceptible to high humidity levels, especially in humid climates or areas with poor ventilation. Excess moisture can lead to mold growth, musty odors, and structural issues. A crawl space dehumidifier helps maintain optimal humidity levels, preventing these problems and improving indoor air quality. The size (capacity) of the crawl space dehumidifier you need depends on the square footage of your crawl space and the level of humidity present. It’s essential to choose a dehumidifier with a sufficient pint-per-day (PPD) rating to effectively remove moisture from your crawl space. Manufacturers typically provide sizing recommendations based on the area and humidity conditions. While a regular dehumidifier can technically be used in a crawl space, it is not recommended. Regular dehumidifiers may not be designed to handle the specific conditions in crawl spaces, such as lower temperatures and restricted spaces. Crawl space dehumidifiers are built to withstand these conditions and perform more efficiently. Yes, crawl space dehumidifiers can be used in conjunction with sump pumps. Some dehumidifiers have built-in pumps that can directly discharge water to the sump pit for automatic removal. Alternatively, you can use a gravity drain or a condensate pump to direct the collected water to the sump pump. The frequency of running your crawl space dehumidifier depends on the level of humidity in the crawl space. In humid conditions, it may be necessary to run the dehumidifier continuously or on a set schedule to maintain optimal humidity levels. In less humid conditions, you can adjust the dehumidifier’s settings accordingly. Crawl space dehumidifiers are specifically designed for use in crawl spaces and may not be as effective in larger areas like basements. For basement dehumidification, it’s best to use a dehumidifier specifically designed for that purpose, as basement dehumidifiers are generally more powerful and can handle larger spaces.Crawl Space Dehumidifiers FAQ's
