Midea Cube 50 Pint Dehumidifier Review: Worth It for Mold?

It helps prevent mold by pulling moisture out of the air, not by treating mold that has already grown. The EPA and IICRC S520 standard both point to indoor humidity above 60 percent as a mold trigger, and to keeping humidity under 50 percent as the main prevention step. The Midea Cube is manufacturer rated to remove up to 50 pints of water a day, and independent lab testing measured it dropping a test room from 90 percent to 40 percent relative humidity in under 8 minutes, the fastest of the 50-pint units that outlet tested. It does not clean mold off a surface or fix a leak. Those still need a cleaning product and a repair.

Midea's own listing rates it for spaces up to 4,500 square feet, but that figure assumes ideal, warm, very humid starting conditions, the way most dehumidifier coverage numbers are marketed. Most single-level basements run 700 to 1,500 square feet, so this unit has real headroom for a full basement, a basement plus a main floor, or a large crawl space. For a single bedroom or bathroom, it is more capacity than you need.

This is the honest catch. Alongside strong moisture-removal performance in independent testing, there is a recurring pattern in owner reviews at Home Depot and Amazon describing units icing up or quitting entirely around the 11 to 12 month mark, just past the 1-year manufacturer warranty. Not every unit fails this way, but the pattern shows up often enough to flag. Register the unit and keep the receipt in case you need to make a warranty claim early.

Independent bench testing by HouseFresh measured it at 42.5 dB on its low setting and 49 dB on high, quiet for a unit in the 50-pint class. That is roughly the level of a quiet office on low and a running refrigerator on high.

Yes. It ships with a built-in condensate pump plus a drain hose, so you can route water uphill to a sink, a window, or a floor drain instead of carrying the bucket. Once the hose is set up and the unit is set to continuous drain mode, it runs unattended without filling the internal tank.

The removable bucket holds 4.2 gallons (about 19 liters), roughly 3 times the capacity of a standard portable dehumidifier tank, so it needs emptying far less often if you are not using the pump. The tradeoff is weight: a full bucket is heavy to lift out and carry, and several owners note the unit and full tank together are awkward to move without the pump and drain hose set up.

It works for basic remote monitoring and Alexa voice control, and lets you set a humidity target from your phone. It only connects to 2.4 GHz WiFi networks, which trips up some households on a 5 GHz-only router. Some owners also report the companion app has not been well maintained, with occasional connection drops. Treat smart control as a convenience feature, not a reason to buy this unit over a non-WiFi model.

It draws up to 425 watts at maximum output and is ENERGY STAR certified, rated to remove about 1.8 liters of water per kilowatt-hour. HouseFresh's own worst-case model, run continuously at full output for a year, put the ceiling near $447 a year in electricity. Most households do not run a dehumidifier at full output around the clock, so realistic day-to-day cost is well under that ceiling, but it is the number to budget against if you plan to run it non-stop through a wet season.

Yes, with two real caveats. It earns 4 out of 5 here. Independent testing found it removed moisture faster than other 50-pint units tested, the tank is large enough to go long stretches without emptying, and the built-in pump makes hands-free continuous drain easy to set up. The catches are a short 1-year warranty and a real cluster of owner reports of units failing right around that warranty's edge. Buy it if you want the fastest-tested moisture removal in its class and you register the warranty. Skip it if a longer warranty matters more to you than raw performance.
