AlorAir Crawl Space Coupon Codes & Deals
Save on AlorAir crawl-space and basement dehumidifiers — 10% off the Sentinel HDi65S, combo packages up to 24% off, plus up to $100 off in the seasonal sale.
How to Save at AlorairCrawlspace
AlorairCrawlspace is AlorAir's direct US store for commercial-grade crawl-space and basement dehumidifiers. These are industrial moisture-control tools rather than the plug-in unit you'd buy for a bedroom — Energy Star certification on several models, automatic defrost, low-temperature operation, and a 6-year limited warranty behind a several-hundred-dollar purchase. The savings come in three distinct forms worth understanding before you buy.
Product-specific codes. AlorAir issues codes tied to a particular unit. At time of writing that includes HDi65S10 for 10% off the Sentinel HDi65S, HD55SGOLD6 for 6% off the HD55S Gold, and NEW3 for 3% off the Helios MP55. These are typed at checkout and apply to the named model — check our AlorairCrawlspace store page for what's currently verified before paying list price.
Combo packages. This is where AlorAir concentrates its deepest discounts. A dehumidifier paired with a matching ventilation fan, or with a 10-mil vapor barrier for full crawl-space encapsulation, carries cuts up to around 24% off at time of writing. If you're treating a whole crawl space rather than swapping one machine, the bundle almost always beats buying the pieces separately.
The seasonal sale. A rotating sale layers up to $100 off select dehumidifiers, fans and bundles with free fast shipping, applied automatically at checkout — the summer sale at time of writing.
Where the Value Concentrates
Combos over singles. For a full crawl-space job, the combo packages are the single most reliable saving because that's where AlorAir discounts most aggressively — a dehumidifier plus fan or vapor barrier at up to 24% off beats a few percent on an individual code.
Size to your space. Buying a unit that's too small for the square footage means it runs constantly and still can't hold humidity down; too large wastes money up front. Matching the model to your coverage is where the real long-run value sits.
Sale windows. The seasonal sale's up-to-$100 automatic discount stacks with free shipping, so timing a single-unit purchase to an active sale is the best way to beat the year-round combo pricing on one machine.
AlorAir Product Range
Sentinel Line
The workhorse crawl-space and basement units — models like the Sentinel HDi65S, HD55S Gold, HDi90 and HDi100, rated from roughly 55 up to 220 pints per day. Many include a built-in pump and drain hose so water can be pushed up and out rather than relying on a gravity drain, and the app-controlled WiFi versions let you monitor humidity remotely.
Helios & Galaxy Lines
The Helios (for example the MP55) and Galaxy (such as the Galaxy 60P) families cover the mid-to-large coverage range with pump-equipped options for continuous drainage. These are the units most often paired into a combo package with a matching ventilation fan for larger or damper crawl spaces.
Fans, Barriers & Encapsulation Kits
Beyond the dehumidifiers, AlorAir sells VentirPro and VentirMax ventilation fans, 10-mil vapor barriers and full encapsulation kits, plus smaller accessories like the Magnetic Dryer Vent Connector Kit. For a complete encapsulation, folding the fan and barrier into a combo package is cheaper than ordering each separately.

Year-round: the combo bundles (dehumidifier plus fan or vapor barrier) are the consistent baseline saving — no seasonal timing required.
During an active seasonal sale: the rotating sale's up-to-$100 automatic discount plus free fast shipping is the best window for a single-unit purchase.
Before a wet season: ahead of spring thaw or a humid summer is when crawl-space moisture problems surface, so buying early avoids paying full price under pressure.
