Who should buy which

Pick the AlorAir Sentinel HDi100 Whole-House Dehumidifier if

Homeowners protecting a large basement, crawl space, or whole-house envelope from moisture, mold, and wood rot who want set-and-forget operation with a built-in pump.

Skip if

You only need to dry a single room or small crawl space (the lower-cost HDi65 or Helios units are a better fit), or you want true HEPA or carbon air purification rather than moisture control.

Pick the AlorAir Sentinel WHD 100 Whole-House Dehumidifier if

A ducted or duct-ready home up to 2,300 sq ft that wants whole-house humidity control with MERV-10 filtration on the airstream and a fresh air damper, sized from the 70 PPD DOE rating rather than the 90 PPD AHAM headline.

Skip if

Your home is larger than 2,300 sq ft (the WHD 120 covers up to 3,000 sq ft), there is no ductwork and no appetite for an install project (the standalone Sentinel HDi100 at $1,050 covers 2,900 sq ft), or you only need to dry a single room or a small crawl space.
