AlorairCrawlspace is AlorAir's direct-to-consumer US store, and the catalog is built almost entirely around moisture control for the parts of a home most people never see: crawl spaces and basements. The core range is commercial-grade dehumidifiers across three families — the Sentinel, Helios and Galaxy lines, rated roughly 55 to 220 pints per day, many with a built-in pump and drain hose — sitting alongside ventilation fans, 10-mil vapor barriers, magnetic dryer vent connector kits and full encapsulation kits.
These are industrial tools rather than the plug-in unit you'd buy for a bedroom. Several models carry Energy Star certification, automatic defrost, low-temperature operation and c-ETL listing, and the brand backs them with a 6-year limited warranty (the first two years full coverage) plus a 24/7 US support line — reassuring for what is a several-hundred-dollar home-improvement purchase.
On value, the store discounts in a few reliable ways. Product-specific codes take a few percent off individual dehumidifiers (for example 10% off the Sentinel HDi65S, or 6% off the HD55S Gold), while the combo packages — a dehumidifier paired with a matching ventilation fan or a vapor barrier for full crawl-space encapsulation — carry the deepest cuts, up to around 24% off. A rotating seasonal sale layers up to $100 off select models with free fast shipping.
Two buying tips at the time of writing: size the unit to your square footage (the model names map to coverage — the HDi65S suits roughly 1,300 sq ft), and if you're encapsulating a whole crawl space, the combo bundles are usually cheaper than buying the dehumidifier, fan and barrier separately.
