Compared side by side
The AlorAir Sentinel HD55P Crawl Space Dehumidifier with Pump appears in this table next to models from other brands:
Who it's for
Encapsulated crawl spaces and basements up to about 1,300 sq ft where the only drain point is above the unit or outside.
Caveats
- The store title says up to 1,500 sq ft, but the spec table says 1,300 sq ft. Plan on 1,300.
- A clogged pump or kinked hose stops the unit with an E4 water-full code. Clean the pump and drain line during routine service.
- The wired wall remote is a $100 add-on.
- AlorAir's other store, aloraircrawlspace.com, listed this unit at $559.73 on 2026-11-11, above the $538.74 this page's link reached at TheDryAir's checkout the same day. Both prices move, so compare the two stores before you buy.
- Discounted orders are not returnable unless the unit is defective.
