Our take

The HDi120 is the pump unit for a large or leaky crawl space that needs more than 100 pints. The AprilAire E130 offers more capacity and an ENERGY STAR listing but has no pump and weighs 98 lb; the HDi120 costs about $900 less and pumps its own condensate.

Not sure this is the right size? Run your square footage and moisture level through the sizing calculator, or compare every unit we cover on the best crawl space dehumidifiers list.
