Midea Cube Dehumidifier Review 2025: The 20-Pint Smart Model After a Year of Cost Tracking

I manage procurement for a property management company with about 40 rental units. I've tracked every appliance purchase, repair invoice, and utility bill in a spreadsheet for six years. So when someone asked me for Midea cube 20 pint smart dehumidifier reviews, I didn't look at marketing pages. I looked at my own cost data after running two Midea Cube 20-pint smart dehumidifiers and two cheap 20-pint units side by side for a year. Here's the short version: the cheap units were not cheaper in the long run.

Midea Cube Dehumidifier Review 2025: What I Actually Compared

I compared four 20-pint dehumidifiers, not 50-pint whole-house units. For a single basement or apartment, 20 pints a day is enough in most climates. The Midea Cube 20-pint smart model cost between $179 and $199 on the major online retail sites in January 2025. The two non-smart 20-pint units I bought cost $109 and $119. That upfront gap of about $70 is exactly where most shopping stops. It shouldn't.

The comparison framework I used was simple: upfront price, energy use, usability, and maintenance. I also added a question most reviews ignore: how often do you have to clean the condenser coils before the unit stops keeping up?

Dimension 1: Upfront Price vs. Total Cost of Ownership

My procurement policy now requires a TCO view before I approve any order. So let's do the math. The cheap unit saves $70 at purchase. But it also draws more power because its compressor runs longer. In my tracking, a non-smart unit ran about 22% more hours per week to keep the same basement at 50% relative humidity. That added roughly $8 a month to the tenant's electricity bill in a humid summer.

Yeah, I know—$8 doesn't sound huge. But over a 4-month humid season, that's $32 a year. Over 4 years, it covers the price difference. And that doesn't include the service call margin. Two things I didn't expect:

• The cheap units both developed frost buildup on the coils and needed the fan replaced after 11 months.
• The Midea units' auto-restart feature kept them running correctly after a power outage. The dumb units sat there in off mode until a tenant complained.

When I compared the repair invoices, the cheap units cost us $145 each to repair. That wiped out the initial savings, plus a headache. I realize $145 is not an official price reference, but that's what we actually paid a local HVAC tech in 2025.

Dimension 2: Energy Use and Runtime

Here's the part of a Midea cube dehumidifier review 2025 that usually gets buried: the smart control matters more than the compressor brand. The Midea Cube's built-in hygrometer actually turns the unit off when humidity hits the setpoint. A cheap analog dehumidifier just keeps running until the bucket is full, or until the room gets so dry it starts feeling weird.

Over the year, the two Mideas used about 18% less electricity per liter of water removed than the cheap units. That number came from our monitoring equipment, not a spec sheet. It's enough to pay for the price difference in about 14 months, depending on your local rate.

Actually, let me correct myself: that was 18% less in the basement units, but 13% less in the two units we moved to a ground-floor office. It depends on temperature and air movement. The point still stands: smart-controlled units run less.

Dimension 3: Smart Features vs. Simplicity

I'm not loyal to smart features. I've seen too many smart thermostats become doorstops when the manufacturer drops support. But with the Midea Cube, the app isn't the main value. It's the ability to schedule and check humidity remotely. I can see if a unit is at 60% before I send a maintenance guy to the property. That's not a toy; that's a trip saved.

The numbers said the cheap unit was the logical purchase. My gut said the smart unit would reduce service calls. I went with my gut. Then a power event in Q2 confirmed it: the Midea unit resumed its last setting, the cheap ones didn't. That's not a subtle maybe-useful feature. It's the difference between a call and no call.

After the first install, I kept second-guessing the premium. What if the Wi-Fi bridge died? What if someone unplugged it? I only relaxed when I realized the Midea Cube works fine as a dumb dehumidifier if you touch its front controls. The app is a layer, not a dependency.

How to Clean Condenser Coils (and Why This Is the Real Cost Guard)

The biggest hidden cost in dehumidifier ownership is clogged condenser coils. Condenser coils are the metal fins on the side or back of the unit. Dust and pet hair build up there, airflow drops, and the compressor starts cycling on high head pressure. That's how a $119 dehumidifier becomes a $200 service call.

Cleaning condenser coils is straightforward, but most people skip it until the unit stops working. Here's the method I use:

1. Unplug the unit and wait a few minutes for the compressor to cool down.
2. Remove the front filter and wash it in warm soapy water. Let it dry completely.
3. Use a vacuum cleaner with a soft brush attachment to remove dust from the coils. Go in the direction of the fins, not against them.
4. If the coils are oily or sticky, use a coil cleaner spray designed for refrigerators or dehumidifiers. Rinse carefully, then dry.
5. Never use a pressure washer, a metal brush, or sharp tools around the fins.

For outdoor condenser coils on an air conditioning system, a Milwaukee leaf blower is actually useful. I use the 18V one on low speed to blow leaves, grass, and cottonwood fluff out of the coil before I rinse it with a garden hose. It cuts the cleaning time in half. But don't use a leaf blower on a dehumidifier's coil—it's too powerful and will bend the fins. For dehumidifiers, stick to a vacuum and soft brushes.

If you're dealing with a hot attic, remember that an attic fan is not a dehumidifier. I've had tenants ask me why a dehumidifier doesn't solve heat in a stairwell. An attic fan is the right tool for venting hot air from a roof cavity; a dehumidifier is the right tool for reducing moisture in a closed, damp space. If you have both problems, you might need both. But before buying an attic fan, check whether the condenser coil on your HVAC system is clean. A dirty coil will make any fan pointless.

What I'd Tell a Procurement Manager: Buy the Midea Cube 20-Pint Smart Dehumidifier for Most Spaces

If you're asking me for a Midea cube 20 pint smart dehumidifier review 2025 with a cost-controller's eye, here's the bottom line:

• Buy the Midea Cube 20-pint smart dehumidifier if you need continuous unattended operation, remote monitoring, or auto restart. The price premium is roughly $70, and the energy difference plus avoided service calls will recover that within a year in a humid space.
• Buy the cheap 20-pint unit only if you need it for one month a year, you have someone who will empty and reset it faithfully, or you treat it as a disposable appliance.
• If you're using it in a dry attic, stop. Measure the relative humidity. If it's below 60%, an attic fan is probably the better money. If it's above 60%, get the dehumidifier.

And learn how to clean condenser coils before you need a technician for it. Fifteen minutes with a vacuum and a soft brush, twice a season, has kept our Midea units running without a single repair in the first year. That's the real smart feature.
