An installation-first shortlist

Basement dehumidifiers with gravity drainage

Compare documented gravity-drain models for a downhill drain route.

If an appropriate drain is below the unit and the hose can stay downhill, a gravity setup may be simpler. Confirm the full path and required clearance before narrowing by capacity.

Santa Fe Compact70

A 12-inch-high cabinet makes this a candidate for a constrained installation. Its two published capacity figures also show why room temperature belongs in the buying decision.

Santa Fe Ultra70

The Ultra70 adds a ducted whole-home use case to a low cabinet. It is deeper than the Compact70, so a height-only shortlist can miss an important installation constraint.

Documented drain arrangement

The AprilAire base models describe a drain or hose setup. Accessories, hose inclusion and configurations differ between variants, so verify the exact package.

Handle the moisture source too

A shortlist cannot assess water entry or the condition of your space. If you are unsure why it is damp, get the building and drainage conditions assessed before choosing equipment.
