Best Small Dehumidifier (20-22 Pint, 2019 Standard)
The 20-22 pint class (current 2019-standard rating) suits closets, bathrooms, and single small-to-mid bedrooms — roughly what used to be marketed as a "30-pint" unit before the 2019 DOE test change. We rank by ENERGY STAR certification and honest drawbacks, using price BANDS only (never exact prices, per Amazon's Operating Agreement).
Before buying this size, confirm your room actually falls in the small-capacity band using the AHAM chart in The Pint Rating Conversion Index — square footage alone isn't enough without your space's dampness level.
Frigidaire FFAD2233W1
22-pint (2019 DOE rating), ~1,500 sq ft moderately damp, ENERGY STAR certified, built-in pump option
One of the few small-capacity units with genuine ENERGY STAR certification under the current 65°F test, so the number on the box is directly comparable across brands.
Best for: Small-to-mid bedrooms, bathrooms, or closets in a moderately damp home
Watch out: The 22-pint rating is a 2019-test number — if you're replacing an old pre-2019 unit rated '30-pint,' this is roughly the equivalent capacity, not a downgrade, but the tank fills faster than a legacy '30-pint' machine's marketing implied.

20-pint (2019 DOE rating), ~1,000-1,500 sq ft, continuous drain hose option, manual humidistat
A straightforward, inexpensive small-capacity unit with a continuous-drain option for set-and-forget use in a closet or crawlspace.
Best for: Budget buyers cooling a single damp room who don't need smart controls
Watch out: Not ENERGY STAR certified on this model — check the specific listing's IEF before assuming best-in-class efficiency, and the manual humidistat is less precise than a digital one.

20-pint (2019 DOE rating), compact footprint, electronic controls, washable filter
A compact, name-brand small unit with electronic controls and a washable filter for basic upkeep.
Best for: Apartments and small bedrooms wanting a recognizable brand at 20-pint capacity
Watch out: 20-pint (2019 rating) is genuinely small-room capacity — don't size this for a basement or multi-room space even though it may be labeled as a direct swap for an old '30-pint' unit.

This class matches roughly 300-800 sq ft at a moderately damp level per AHAM's chart, less for damper spaces. See How Many Pints Do I Need? for the full breakdown by dampness level (this guide applies the same logic outside basements).
