Our take

Consider the HDi100 when a crawl space is too large for the HDi90's 2,600 sq ft rating and condensate has to be pumped. It is heavy at 88 lb and rated under 60 dBA, the loudest published figure here, so it suits a crawl space away from living areas. The AprilAire E100 has the same AHAM rating with ENERGY STAR certification but no pump.
