Midea Cube MAD20S1QWT 20-Pint Smart Dehumidifier

Moisture Removal Performance

Dehumidifier Buyers Guide measured the MAD20S1QWT pulling a 50 sq ft chamber from 90% RH down to 40% RH in 13 minutes 25 seconds — the fastest of any 20-pint unit they have tested. Tom's Guide's Dan Cavallari ran a 100 sq ft basement bathroom test that pulled humidity from 85% to a 33% setpoint in about three hours under normal operation. That maps to roughly 20 pints per day of moisture extraction in real-world residential conditions, which matches the AHAM-rated specification.

The headline finding from Tom's Guide was that the Cube reached a lower humidity than the setpoint because Cavallari forgot to enable auto shut-off — the unit continued past the 35% target to 33% on his first run. Consumer Reports' lab gave it a "very good overall" rating with high marks for both performance and convenience in the 20-pint category. For its size class, this is the unit to beat.

Coverage and Room Size Fit

Midea markets the MAD20S1QWT for up to 1,500 square feet, but realistic effective coverage in moderate to severe humidity is closer to 500 to 800 square feet — a single bedroom, a finished basement bathroom, a home office, or a small RV interior. Dehumidifier Buyers Guide explicitly framed it as the right answer for buyers who do not need to cover a whole basement and want lower noise and lower power draw than the bigger Cubes.

For a moderately humid 600 sq ft master bedroom or a damp 400 sq ft bathroom, this is the right size. For a 1,000 sq ft basement or a multi-room main floor, step up to the 35-pint MAD35S1QWT. The 20-pint capacity is also a good match for storage spaces and crawl-space-adjacent utility rooms where the larger Cubes' noise would be overkill.

Setup and Drain Options

The standard MAD20S1QWT ships with gravity drain hose only — no built-in pump on this SKU. A pump variant exists at higher price, but the base unit assumes the drain destination is at or below the unit's outlet. Tom's Guide's reviewer plumbed the gravity hose to a basement floor drain and noted setup took under five minutes; the bucket option works for low-humidity or short-cycle use.

The tank itself is one of the unit's killer features: 3.2 gallons (25.6 pints) is the same tank as the 35-pint Cube and almost three times what competing 20-pint dehumidifiers offer. That extra capacity means a homeowner can run the unit on the bucket for an entire weekend trip without coming home to a stopped appliance. Dehumidifier Buyers Guide called the tank capacity "exceptionally large relative to similar products" and credited it as the main reason this unit wins on usability.

Noise and Bedroom Friendliness

Dehumidifier Buyers Guide measured 58.6 dB on low and 59.8 dB on high — the quietest 20-pint unit they tested. Tom's Guide's Cavallari noted a metallic resonance sound during compressor cycling that some users will find more annoying than the raw dB number suggests. Most reviewers and most Amazon customers describe it as background-level fan noise rather than an intrusive whine, but the metallic note is real.

For a quiet sleeping space, the 59 dB measurement is at the loud end of what most light sleepers tolerate. Heavy sleepers and white-noise tolerant users will find it perfectly fine. The unit is genuinely usable in a bedroom — unlike the 50-pint Cubes — and the smaller chassis tucks away in a corner or closet better than the larger siblings. Lights are dimmable through the app for nighttime use, which is a nice touch.

Energy Use and Long-Term Cost

Dehumidifier Buyers Guide measured 262 watts at 50% RH — the lowest power draw of any 20-pint unit in their test set. Running this in a 600 sq ft bedroom 10 hours a day at U.S. average residential rates works out to roughly $30 a summer in electricity, which is at or below what a window-mounted air conditioner uses for ventilation alone. The Energy Star Most Efficient certification holds up in real-world use.

Sticker price typically lands in the $200 to $230 range — substantially below the 35-pint MAD35S1QWT and well under the 50-pint Cube. For buyers who only need to dehumidify a single room, this is the cost-effective choice both up front and over the long term. The same one-year warranty caveat applies to this SKU as to the rest of the Midea Cube line.

Smart Features

Tom's Guide's Cavallari highlighted the MideaAir app as "simple and intuitive" — easier to use than most appliance apps in 2026. Wi-Fi setup took roughly three minutes after the initial 2.4 GHz hurdle. Alexa and Google Assistant integration both work, and the unit retains state through power outages with auto-restart enabled. App features include scheduling, target humidity, fan-speed selection, and a basic readings dashboard.

The same critiques that apply to the rest of the Midea Cube line apply here: the app hasn't received updates in over a year, and there are no advanced automations tied to outdoor forecasts. For a small-room appliance the user is likely to touch infrequently, the basic feature set is appropriate — but power users who want sophisticated automation should look elsewhere. The dimmable LED is the small touch that makes nighttime bedroom operation tolerable.

What Reviewers Loved

Dehumidifier Buyers Guide gave the unit a 4.7/5 editor's score and called it "the best small dehumidifier we've tested" — high praise from a site that has run dozens of units through controlled tests. Tom's Guide's Cavallari concluded it "works quietly and quickly, and is more compact than most units in this capacity class." The combination of large tank, lowest power draw in class, and quietest noise floor in class is unique in the 20-pint space. Reddit users in r/Dehumidifiers consistently flag this as the right answer when someone asks for a small unit.

Where It Falls Short

The metallic compressor resonance Tom's Guide flagged is the most-cited subjective issue — the raw dB number is quiet but the timbre of the noise is harder to tune out than a pure fan whine. Amazon reviewers describe it as either invisible background noise or unexpectedly annoying with little middle ground. Light sleepers should expect to run a white-noise machine alongside it.

The 20-pint capacity is small enough that this unit cannot substitute for a 35-pint or 50-pint Cube in a basement application. Buyers who buy this expecting whole-home coverage will be disappointed — it is purpose-built for a single small room. The pump-less standard SKU means installations requiring upward water lift need either the higher-priced pump variant or an aftermarket pump kit. And the same one-year warranty trails the five-year Honeywell coverage.

Who It's Best For

The MAD20S1QWT is the right pick for someone who needs dehumidification in a single room of 500 to 800 square feet — a bedroom, master bathroom, finished basement bathroom, small home office, or RV interior. It is particularly well-suited as a paired second unit when the homeowner has a 35-pint or 50-pint Cube downstairs and needs separate quieter coverage for an upstairs bedroom. The low power draw makes it practical to leave running continuously through a summer without flinching at the electric bill.

It is not the right pick for whole-home or whole-basement coverage — the 20-pint capacity simply cannot pull the volume of moisture a larger unit can. Buyers with severe Gulf Coast humidity in a single bedroom may find it cycles continuously rather than holding setpoint with room to spare; in those cases, sizing up to the 35-pint Cube is the better play. And users sensitive to metallic compressor resonance should consider the quieter dual-inverter alternatives like LG PuriCare instead.
