Best 20 Pint Dehumidifiers (2026)

The Midea Cube is built around a larger bucket in a smaller footprint. The listing says the tank holds up to three times what its earlier compact model did, which stretches the interval between emptying and makes the hose-free setup less of a chore. It is also the one pick here whose pint number is spelled out against the current DOE test, with the listing saying 20 pints on that scale is comparable to 30 pints on the older 2012 test.

That honest labeling is the main reason it leads this list. A 20 pint figure on the 2019 scale is a real figure at 65 F and 60 percent humidity, so you can reasonably expect it to behave like a 20 pint machine in a temperate basement room. Against the 21 pint GoGuess it gives up a pint of paper capacity but trades that for an Energy Star certificate and a brand that publishes the test condition. The tradeoff is size: it covers a single room well and struggles once you ask it to handle a whole open basement.

Ownership is simple. You wash the air filter, rinse the bucket so it does not grow slime, and park the unit with a few inches of breathing room on every side.

GoGuess builds this unit around a compressor with an automatic humidity regulation function and three modes: Dehu, Turbo and Sleep. Dehu holds a target humidity, Turbo pushes the fan harder to pull a damp room down quickly, and Sleep drops speed and light for night use. The mode set is the practical edge here, because it lets one machine act as a quiet bedroom unit at night and a faster drying unit when laundry hangs in the room.

The phrase to watch in the listing is Max 21 pints per day. The word Max normally means the rating was taken under warm, humid conditions, so a cool 60 F basement will not produce 21 pints. Next to the Midea Cube, which states its test basis, treat this as a 15 to 18 pint unit in a cool room and a full 21 pint unit in a warm laundry. That is still a fair amount of drying for a 1,600 sq ft rating on a mildly damp space.

Ownership is routine: wash the filter, empty or hose the water, and watch noise as the compressor ages. A hose drain is included, which is a quiet advantage for anyone running it in a laundry room beside a floor drain.

The TCL is the plain, no-frills pick in this list, and that is what earns it the value badge. It has a precise humidity setting, a 24 hour timer, a bucket-full indicator with an audible alarm, and auto restart that returns it to its saved settings after a power outage. Those four features are exactly what a basement unit needs, because a dehumidifier in a room you rarely visit must handle outages and a full bucket without you.

Its 2,000 sq ft coverage line is bigger than the 1,500 sq ft Midea or Whirlpool, but do not read that as a stronger machine. Both are 20 pint class units, and the larger figure is a more optimistic coverage assumption under mild conditions. Against the GoGuess, the TCL lacks a hose-focused design and a boost mode, so it fits best in a space where you can empty the tank every day or two or where the humidity is not severe.

Expect a conventional body with casters, a bucket you carry to a sink, and an air filter you rinse every few weeks. The audible alarm is the thing owners notice, because it turns a forgotten bucket from a mess into a beep.

Whirlpool sells this model as a general moisture and odor machine for basements, bedrooms and utility rooms. It removes up to 20 pints per day from a 1,500 square foot space per the listing, comes with an auto shutoff when the bucket fills, and has an adjustable humidity control with a timer. The feature list matches the TCL almost point for point, so the choice between them comes down to coverage claim and brand preference.

Because the coverage figure is lower than the TCL's, Whirlpool's own claim is the more conservative of the two for the same pint class. A conservative claim is a mild plus when you are trying to avoid a machine that is oversold, though in practice both will fit the same 20 pint job.

Long-term, all compressor units of this size share one weak point: the compressor and fan run hard in humid, dusty basements. Rinse the filter regularly, keep dust off the coil and check the bucket float seal once a season.

RCA's listing leans on the continuous drain feature, telling you to connect a garden hose and let it drain to a low floor drain. That is the right call for a basement dehumidifier, because most owners of this size unit eventually stop emptying a bucket and let the machine run to a drain. Four smooth casters help too, so you can roll it between a laundry corner and a storage area without lifting a unit of that weight.

Stack it against the Whirlpool and TCL and the tradeoff is clear: all three claim 20 pints, but the RCA puts its drain option at the front of the listing, while the others stress timers and alarms. If your install point has a low drain nearby, this one makes sense.

A hose drain adds one ownership step worth remembering. Kinks in the hose or a slight uphill run will make the pan fill, and the machine will shut off on its float.

Trazico offers a 21 pint figure with two drainage options and three humidity targets, so you choose a level instead of a single set point. Choosing a target tied to a named outcome is handy for people who find a raw percentage confusing. The unit is pitched as a basement and large-room machine, which is a realistic fit for a 1,500 sq ft rating.

The 21 pint number is the same kind of claim as the GoGuess, 'up to' figures that assume warmer and wetter air than a cool basement delivers. Of the two, the GoGuess has a Sleep mode and Turbo, while the Trazico has a simpler target-based scheme.

Place it away from the wall with space on all sides, and plan to wash the filter often because a bedroom collects more lint than a basement. If the room is cold in winter, expect the unit to spend part of its cycle defrosting.
