Midea Cube Dehumidifier Review: The Best in the Category (With One Catch)

The Midea Cube is the most interesting dehumidifier line on the market, and across independent testing it's also the most successful: different sizes of it win the small-room, mid-size, and basement categories outright. We reviewed the flagship — the 50-pint with pump — and the two smaller siblings, and the story is consistent.

The folding-tank design, and whether it helps

The Cube's trick is a body that collapses for storage and expands to reveal an oversized reservoir — about 4.2 gallons on the 50-pint, roughly triple a normal tank. It sounds gimmicky; it isn't. The single most annoying thing about a dehumidifier is emptying it, and we found the spread between the best and worst tank-to-capacity ratio is nearly eightfold. The Cube 50 holds more water than a conventional 50-pint even while removing more of it.

The 50-pint with pump: the basement pick

The Midea Cube 50 with pump is HouseFresh's top overall dehumidifier, and it's ours for basements. The built-in pump lifts water up to sixteen feet, so it drains to a sink or out a window with no floor drain needed — the feature that makes it genuinely set-and-forget. It's ENERGY STAR Most Efficient and measured at 42–49 dB, near-silent for its capacity.

The 20 and 35: quiet and smart, scaled down

The Cube 20 is independently the quietest and most efficient small unit tested — the bedroom pick. The Cube 35 is the value-smart middle: the same platform without the pump, for about $229. All three share Wi-Fi, the big tank, and low noise.

The catch: the app and the warranty

It's not all praise. The Midea Air app is 2.4 GHz-only, awkward to pair, and reportedly no longer actively updated — the weakest part of the experience by a distance. The warranty is a single year, and there are scattered owner reports of icing or failure after a year or two.

And on raw value the Cube loses: the Frigidaire FHDD5034 buys more pints per dollar than any Cube. What you're paying Midea for is the tank, the quiet, and — on the 50 — the pump.

Which Cube?

Bedroom or small room: the 20. Normal damp room, no pump needed: the 35. Basement, or anywhere you can't drain downhill: the 50 with pump. If you're weighing a Cube against the cheaper workhorse, our Cube 35 vs Frigidaire breakdown is the place to start.

Verdict

The best dehumidifier hardware in the category, held back only by software. For buyers who want quiet, a big tank, and hands-off drainage, a Cube is the answer — pick the size that fits your space.
