Dehumidifiers
Basement, crawl space and whole-home units, sized correctly.
Buying guides
- The best crawl space dehumidifiersFor most sealed crawl spaces, buy the Santa Fe Compact70: 70 pints a day at 80°F/60%, a 12-inch-tall cabinet, a MERV-13 filter and a 6-year warranty. If the space runs cold or you need a pump in the box, the AlorAir Sentinel HDi90 is the value pick; if you want to duct it or run a wall control upstairs, the AprilAire E080 is the upgrade.Updated October 30, 2026
