Why it matters
The Honeywell Energy Star A120D 120 Pint Whole House Dehumidifier is a whole-house (ducted) dehumidifier, rated for 3500 sq ft and removing up to 120.0 pints/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 3,500 square feet is above the middle of the range we cover: 54 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 middle third of the 12 whole-house models we cover when we checked; the button shows today's price.
It qualifies for our list Best Whole-House Dehumidifiers, where it is ranked against every model that meets the same rule.
Compared with the Honeywell Energy Star A90D 90 Pint Whole House Dehumidifier (DHM090R4000/U): rated room size 3500 sq ft here vs 2800 sq ft.
Warranty, per the maker: 5-Year Warranty.

Pros and cons
Pros
- 120.0 pints/day removal
- Rated for 3500 sq ft
Cons
- Needs regular cleaning to stay hygienic
Limitations to weigh
- Not stated on the Honeywell Energy Star A120D 120 Pint Whole House 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.
