Why it matters
The ALORAIR Sentinel HD90 Dehumidifier is a crawl space and basement dehumidifier, rated for 2600 square feet and removing up to 90 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.
Its rated area of 2,600 square feet is below the middle of the range we cover: 46 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 dearest third of the 25 basement / crawlspace models we cover when we checked; the button shows today's price.
It qualifies for our lists Best Dehumidifiers for Basements, Best Crawl Space Dehumidifiers, where it is ranked against every model that meets the same rule.
Compared with the ALORAIR Pump 1300 Dehumidifier: rated room size 2600 square feet here vs 1300 square feet.

Pros and cons
Pros
- 90 pints per day removal
- Rated for 2600 square feet
Cons
- Needs regular cleaning to stay hygienic
Limitations to weigh
- Not stated on the ALORAIR Sentinel HD90 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.
