Crawl space damp again this summer? Every AlorAir offer below is already locked in — no codes to copy, no checkout fumbling. Click any deal and your savings travel with you to aloraircrawlspace.com automatically.
💰 The biggest sitewide saving in the July sale. Building a full crawl space system — dehumidifier, ventilation fan and vapor barrier together? This tier pays for the accessories.
✨ The sweet spot for most homeowners — a Sentinel HDi90 or Galaxy 85P plus a fan usually lands right in this bracket. Discount is applied for you at checkout.
🎉 The easiest tier to hit — nearly every crawl space dehumidifier in the range qualifies on its own. Free money on an order you were already placing.
👀 The deepest markdowns on the whole site — open-box units, discontinued colourways and end-of-line accessories. Stock is genuinely limited and does not restock.
💧 Summer Sale pricing across the Sentinel and Galaxy ranges — HD35P, HD55, HDi65S, Galaxy 60P and more, all marked down between 15% and 25% for July.
🌀 The VentirPro 540 drops to under $70 and the VentirPro-S2, VentirMax 300S and VentirPro 260S are all 20% off. Pair one with a dehumidifier for proper air movement.
🎁 A July-only bonus: selected dehumidifiers ship with a free installation accessory kit and a spare MERV filter included in the box. No add-to-cart needed.
📦 Buying the dehumidifier and the ventilator separately costs more. The HD35P + VentirPro 540 combo, the Galaxy 60P bundle and the HDi90 encapsulation kit are all discounted together.
🚚 No shipping fees and no minimum spend, shipped from the AlorAir warehouse in Chino, California. Stacks with every other offer on this page.

Best-selling crawl space and basement units with their current sale pricing.
Summarised from verified customer reviews published on aloraircrawlspace.com.
Editor's Pick
Art replaced a five-year-old competitor unit in his basement and reported the AlorAir runs as a steady low drone rather than a loud start-stop cycle, so it no longer needs to be scheduled off overnight. He also noted the on-unit humidity reading sits a few points above his separate hygrometer.

Bestseller
Nick in Tennessee described the 70-pint unit as one of his better home investments: musty basement odours gone, a measurable humidity drop inside 24 hours, straightforward setup, intuitive controls and continuous drainage so there is no bucket to empty.

Big Spaces
A five-star reviewer writing as "Mrs. Truth" found the Galaxy 60 pulled moisture out quickly, kept the basement free of musty smells, and stayed quiet for a unit of that capacity. She rated the build as durable and the control panel as simple to use.

85% → 55%
A reviewer posting as "Wiz" installed the HDi100 in a crawl space whose damp was pushing humidity up through the house. Within two to three days the crawl space fell from around 85% to 55% and the house readings returned to a safe range.

Set & Forget
Khan bought the 70-pint pump model for a 1,000 sq.ft crawl space and highlighted the roughly 19.6 ft vertical discharge, the corrosion-resistant casing that still looked new after weeks in a damp space, plus auto defrost and power-outage memory restart.

Support Story
Paul, an engineer, opened his 2023 unit for routine cleaning in late 2025 and found no rust. When a motherboard fault appeared, support answered the phone in seconds, diagnosed it from a short video, shipped a replacement board free and linked a fitting guide. Swap took about ten minutes.

AlorAir builds commercial-grade dehumidifiers, ventilation fans, air filtration systems and encapsulation kits for the parts of a home most people never look at — crawl spaces, basements, garages, wine cellars and warehouses.

The company reports a 98% satisfaction rate across more than 1.2 million customers, holds around 200 patents, and runs about 120 repair centres. Units are Energy Star certified and ETL listed, ship from Chino, California, and carry a 6-year limited warranty with the first two years fully covered, plus 30-day returns.

Everything worth knowing before you buy a crawl space dehumidifier.
Because you don't need one. AlorAir's July offers are built into the link — the sitewide $20 / $50 / $100 tiers and the sale pricing apply automatically once you click through from this page and reach checkout.
The clearance sale, at up to 50% off, gives the deepest single markdown — though stock is limited. For a full-price current model, the July Summer Sale runs 15–25% off, and the $100 off $1,499+ tier is the largest fixed saving.
Yes — the $20 / $50 / $100 tiers are applied to your order total after sale pricing, and free shipping applies regardless. The tiers themselves don't stack with each other; you get whichever one your total qualifies for.
As a rough guide: up to 1,000 sq.ft use the Helios D35 or Sentinel HD35P (70 PPD); 1,200–1,300 sq.ft the Sentinel HD55 or HDi65S (113–120 PPD); 1,800–2,300 sq.ft the Galaxy 60 or 85P (145–180 pint); 2,600 sq.ft and beyond the HDi90, HDi100 or HDi120. Very damp or poorly sealed spaces should size up a step.
Only if the water can't drain downhill. Models ending in "P" (HD35P, HD55P, Galaxy 60P, MP35) have a built-in condensate pump that can push water vertically — around 19.6 ft on the Helios MP35 — which matters when your crawl space sits below the drain point. If gravity drainage works, the non-pump model is cheaper.
For a sealed, encapsulated crawl space the dehumidifier plus a vapor barrier is the core setup. A VentirPro or VentirMax fan helps move air in vented crawl spaces and larger footprints. Buying them as a combo bundle is currently up to 24% cheaper than buying separately.
Dehumidifiers carry a 6-year limited warranty, with the first two years being full coverage. Returns are accepted within 30 days. Registration is handled on AlorAir's warranty page.
Yes — free and fast shipping applies to every order with no minimum spend, dispatched from AlorAir's US warehouse at 14752 Yorba Ct, Chino, CA. That also means US-based support and repair rather than overseas RMA.
The current Sentinel and Galaxy models are Energy Star certified, so running costs are lower than older non-certified crawl space units. Auto defrost also stops the compressor wasting energy icing up in cold weather.
Record a short clip of your AlorAir unit installed and running, then submit it through the Earn Rewards page on aloraircrawlspace.com. The $20 is paid back instantly on approval and is separate from any purchase discount you used.
