About AlorAir
AlorAir Solutions Inc. is a California-based company founded in 2012 and headquartered in Chino, California, with additional R&D and manufacturing operations in China and regional offices in the UK and Australia. The company specializes in designing and manufacturing air-handling equipment for the water-restoration and residential moisture-control markets — commercial and crawlspace dehumidifiers, whole-house dehumidifiers, HEPA air scrubbers, and air movers — and has sold commercial and crawlspace dehumidifiers on Amazon since October 2019.
AlorAir's commercial dehumidifiers carry cETL certification for continuous, unattended operation, and current models are backed by warranties up to six years — several times longer than the one- to two-year coverage typical of residential-tier competitors. In our own review of the Sentinel HD55S, what stood out was the commercial-grade metal housing and low-profile 22.5-inch horizontal design, built specifically to fit encapsulated crawl spaces where plastic-housing consumer units aren't engineered to run 24/7 for years without service.

AlorAir Sentinel HD55S Crawl Space Dehumidifier
Commercial-grade metal housing built for continuous unattended operation in crawl spaces, mechanical rooms, and unconditioned basements where plastic-housing consumer units fail prematurely. The 5-year warranty is the longest in our roundup, the low-profile 22.5-inch horizontal design fits encapsulated crawl spaces where vertical-standing units cannot, and cETL certification confirms it's rated safe for 24/7 unattended operation.

- Founded in 2012 and headquartered in Chino, California, AlorAir has focused specifically on air-handling equipment — commercial and crawlspace dehumidifiers, whole-house dehumidifiers, HEPA air scrubbers, and air movers — since entering the water-restoration and moisture-control markets.
- Commercial dehumidifiers are cETL certified for continuous, unattended operation, and current models carry warranties up to six years, well beyond the one- to two-year coverage typical of residential-tier competitors.
- The Sentinel HD55S earned DIYRated's Runner-Up pick for encapsulated crawl spaces: metal commercial-grade housing, a 22.5-inch low-profile horizontal design built for tight crawl space install environments, and the longest warranty in our roundup.
- Selling commercial and crawlspace dehumidifiers on Amazon since October 2019, with a catalog broad enough to cover an entire restoration or moisture-control job — dehumidifiers, HEPA air scrubbers, air movers, ventilation fans, and crawl space vapor barriers under one brand.
- Company-owned manufacturing of core dehumidifier components — rotational molding, filter mesh, and sheet metal production — gives AlorAir direct control over build quality rather than relying on third-party OEM suppliers.
