Choosing the Right-Sized Dehumidifier for Your Crawl Space
When it comes to effectively controlling moisture in a crawl space, selecting the appropriate-sized dehumidifier plays a critical role. The dimensions, humidity levels, and specific conditions of your crawl space influence the size and capacity of the dehumidifier required to maintain an optimal environment.

Factors to Consider

Crawl Space Size:
Measure the square footage of your crawl space accurately. Larger crawl spaces may require higher-capacity dehumidifiers, while smaller spaces may suffice with lower-capacity units.

Humidity Levels:
Evaluate the average humidity levels in the crawl space. If your area experiences high humidity, a more powerful dehumidifier will be necessary to manage moisture effectively.

Temperature Conditions:
Consider the temperature fluctuations within the crawl space. Some dehumidifiers perform better in lower temperatures, making them suitable for cooler crawl spaces.

Choosing the Right Size

Matching Capacity to Crawl Space Size:
For crawl spaces up to 1,500 square feet, a dehumidifier with a capacity of 30 to 50 pints per day may suffice. Larger crawl spaces, between 1,500 to 3,000 square feet, might need units with capacities ranging from 50 to 70 pints per day or more.

Consider Energy Efficiency:
Opt for energy-efficient models that can effectively remove moisture without consuming excessive energy, ensuring cost-effective operation.


Selecting the right-sized dehumidifier is pivotal to maintaining a dry and healthy crawl space environment. By considering factors such as crawl space size, humidity levels, and moisture sources, you can make an informed decision. Moiswell offers a range of commercial dehumidifiers with various capacities to suit different crawl space dimensions and moisture levels.
