This AprilAire dehumidifier is made with rust-resistant aluminum coils, and it includes a washable filter that only needs to be cleaned or replaced once a year.

The AprilAire E100 is that it doesn't come with a condensate pump so that will be extra if you can't do gravity drainage to a sump pump or exterior.

The AirWerx55 by BaseAir is our top pick for the best crawlspace dehumidifier that is the most portable.

It comes with two handles and it is light enough that it can be easily moved to a different area for dehumidification. 

It is also equipped with epoxy-coated coils to help prevent corrosion and freon leakage (a common problem in dehumidifiers).

The AirWerx55 includes a MERV-8 filter to catch larger airborne particles to prevent contamination. One cool feature of this dehumidifier is that it has an auto-restart function so that you don't have to go into the crawl space just to restart it if there is a power out.

Some home depots also allow rentals of the Dri-Eaz if you just need a temporary fix.
