Why it matters

The ALORAIR HS35 Dehumidifier is a crawl space and basement dehumidifier, rated for 1000 square feet and removing up to 35 pints per day a day.

Aim for 40 to 60 percent relative humidity indoors: drier air irritates airways and skin, wetter air feeds dust mites and mold.

The listing names a commercial-grade build.

Its rated area of 1,000 square feet is one of the smallest ratings we cover: 11 of the 99 dehumidifiers with a stated figure come in lower, and the range runs from 110 square feet to 7,500 square feet.

Price-wise it sat in the cheapest third of the 25 basement / crawlspace models we cover when we checked; the button shows today's price.

It qualifies for our list Best Crawl Space Dehumidifiers, where it is ranked against every model that meets the same rule.

Compared with the ALORAIR Sentinel HD90 Dehumidifier: rated room size 1000 square feet here vs 2600 square feet.

Pros and cons

Pros

  • 35 pints per day removal
  • Rated for 1000 square feet

Cons

  • Needs regular cleaning to stay hygienic

Limitations to weigh

  • Not stated on the ALORAIR HS35 Dehumidifier listing: bucket size, power draw. Ask the seller or check the manual before relying on it.
  • Pints-per-day figures depend on the test conditions; since 2019 the US test uses cooler, drier air, so newer ratings look smaller than older ones for the same machine.

1000 square feet, per the listing. Drafty rooms, high ceilings and open stairways need more capacity than the rating suggests.

Up to 35 pints per day under its rating conditions; a cooler basement gives less.
