The Santa Fe Oasis105 Dehumidifier is Santa Fe’s most versatile and energy-efficient dehumidifier, for whole homes, basements, attics and crawl spaces. For more models, see our Whole-House & Crawl Space Dehumidifiers page.
Our Verdict
The Oasis105 is our top Santa Fe pick because it fits so many jobs, and its no-P-trap drain cuts maintenance.
It is very expensive and the listing gives few specifications, so ask your installer for the spec sheet.

Design
The body measures 16 x 14.5 x 24 inches with integrated handles for installation.
Santa Fe’s patented ECCO coil optimization uses corrosion-resistant dual-coated coils.
Controls
Onboard digital controls and a variable speed fan let it match airflow to the space, and a dew point cut-out protects it in cool conditions.
Its positive pressure condensate drain needs no P-trap, and it restarts automatically after a power outage.
Placement Tips
In a crawl space, set the unit level on a vapor barrier, blocks or a hanger kit, away from standing water, with clear space around the intake and outlet. Run the drain hose with a steady downhill slope, or route the pump line to a sink, sump or exterior opening.
Seal vents and lay a vapor barrier first. A dehumidifier in a vented crawl space spends its effort drying outdoor air.
Running Costs and Care
Check the filter every month or two during heavy use and rinse or replace it when dirty. Make sure the drain line stays clear and, on pump models, test the pump occasionally.
Set the humidity target around 50% to 55%. The compressor then cycles off once the space is dry, which keeps running costs down.
How It Compares
Against the Santa Fe Compact70, the Oasis105 is larger and more versatile, with digital controls.
Against the AprilAire E100, both suit whole homes; the Santa Fe adds a variable speed fan and no-P-trap drain.
