How this dehumidifier scores for different use cases
With 35 PPD capacity (70 at saturation), continuous gravity drain, and auto-defrost, this unit handles basement moisture well. Coverage up to 1,000 sq ft suits smaller basements but falls short for larger ones.
Compact dimensions (15.35 x 11.2 x 11.4 inches) help in tight spaces. However, at 39.7 lbs with no wheels, moving it around is not easy.
Under 50 dB is acceptable but not quiet enough for light sleepers. No sleep mode, no timer, no auto-shutoff, and no display-off feature limit its bedroom suitability.
The compact, crawl space design is commercial in nature, and the cETL certification adds credibility. However, 35 PPD capacity is too low for most commercial or restoration applications.
Only 1,000 sq ft coverage and 35 PPD capacity are far too low for whole-house use. No pump drain and no smart controls make large-area management impractical.
No Wi-Fi, no app control, no remote control, and no smart home integration of any kind. Manual knob operation only.
Our Verdict
The AlorAir HS35 is a purpose-built crawl space dehumidifier. It pulls 35 pints per day and handles up to 1,000 sq ft.
Its compact frame fits where bigger units cannot go. At just 15.35 x 11.2 x 11.4 inches, you can slide it into tight crawl spaces with room to spare.
The 6.5-foot gravity drain hose lets you set it and walk away. Auto-defrost keeps it running in cold conditions where other units would freeze up.
You get a 5-year warranty, which is among the best in this class. The cETL certification confirms it meets electrical safety standards.
The trade-off is clear. You give up smart features, auto mode, and a built-in pump. There is no Wi-Fi, no timer, and no remote control.
At $382, you pay a fair price for a specialized crawl space tool. If you need a simple, reliable dehumidifier for a small basement or crawl space, this unit delivers.
Buyers who want app control or whole-house coverage should look elsewhere. This unit does one job and does it well.
What We Like
- 5-year limited warranty gives long-term protection for your investment
- Auto-defrost lets this unit run in cold crawl spaces and basements down to low temperatures
- Compact size at 15.35 x 11.2 x 11.4 inches fits easily in tight crawl spaces
- Continuous gravity drain with 6.5-foot hose removes water without you emptying a tank

What Could Be Better
- No wheels make it hard to move at nearly 40 pounds
- No Wi-Fi, app control, or remote control for monitoring from another room
- No auto mode or timer means you must adjust settings by hand
- Only 1,000 sq ft coverage limits use in larger basements or open areas
- No built-in pump drain requires gravity-based drainage setup only
