Key Features to Look For
When you shop for a crawl space dehumidifier, keep these important features in mind:
- Moisture Removal Capacity: This is measured in pints per day. A larger capacity unit can remove more water from the air. For most crawl spaces, a unit that removes 50-70 pints per day is a good start. Bigger spaces might need more.
- Coverage Area: Dehumidifiers are rated for specific square footage. Make sure the one you choose can handle the size of your crawl space.
