What to know about Midea MAD50S1QWT

A 50-pint compressor dehumidifier rated for up to 4,500 sq ft. Its lift-and-twist design nests for storage and extends into a very large bucket, and it has Wi-Fi/app control and a gravity drain hose. Reviewed names it best overall: in its tests it lowered humidity fastest of the 50-pint units while drawing the least power. It suits large basements where you want days between emptying.
Editorial notes

Why it stands out

Why we like it

Reviewed named it its best overall dehumidifier. In its tests it lowered humidity faster than the other 50-pint units while drawing the least power. Family Handyman also recommends it for basements.

The tank extends to about 33.8 pints, so you can go days between emptying. With the included hose running to a floor drain or sump, you may not empty it at all.

What to know

Skip it if you have no nearby drain, or if the price matters. Right now it is priced well above the pump version, which makes the #1 pick the better buy for most people.
Performance

Score breakdown

Moisture Removal Performance

Measured water removal and how fast a unit pulls down humidity in real basement or chamber tests (Bob Vila, Reviewed, Tom's Guide, RTINGS, Consumer Reports). Rated pints/day for the space size counts too.

9.0
Fastest humidity pull-down of the 50-pint units in Reviewed's tests.
Basement Suitability

Coverage for large spaces, low-temperature operation and auto-defrost, continuous drain or built-in pump, auto-restart after power loss, and casters/handles for stairs.

7.8
Rated for 4,500 sq ft, with gravity drain and a large tank. No pump.
Ease of Use & Emptying

Bucket size and how easy it is to remove and carry, hose included or not, controls and app, and how accurate the humidistat is.

8.3
Very large nesting tank and app alerts. Heavy when full (Family Handyman).
Noise

Measured or reported noise at normal and high fan speeds. This matters for finished basements and rooms above.

5.8
Same Cube 50 platform that RTINGS rated poor for noise (5.7, measured on the pump version).
Energy Efficiency

ENERGY STAR v6 certification, IEF (L/kWh), and power draw measured in tests (e.g., Reviewed's power measurements).

8.5
Lowest power draw among the 50-pint units in Reviewed's tests. ENERGY STAR certified.
Value

Street price relative to capacity, features and tested performance, plus warranty length.

5.5
$435.90 from a third-party seller is poor value next to the $249.99 pump version.
