Midea Dehumidifier Review: What You're Actually Buying
Search the brand and you get a wall of boxes saying the same thing: 50 pints, 4,500 sq ft, smart. Four of them sit within $120 of each other and the photos are nearly identical. None of them mention the number that decides how the machine lives in your basement — the bucket holds about 13 pints, and the unit is rated to pull 50 a day. That's four trips up the stairs with a sloshing tank, unless you buy the version that drains itself.
Why every Midea looks bigger on the old scale
A "50-pint" Midea is not the 50-pint machine your neighbor bought in 2016. In 2019 the Department of Energy moved the test condition for portable dehumidifiers from 80 °F down to 65 °F; cooler air holds less water, so every unit on the market lost about 30% of its printed number overnight without a single part changing. A current 50-pint is the old 70-pint class, a current 20-pint roughly the old 30. Read a ten-year-old forum thread and the numbers won't line up — which is how people end up one size too small.
Second: Midea Group is a contract manufacturer as much as a brand, building dehumidifiers that ship under other American nameplates. The chassis in a Midea box and the one in a competitor's box at a $60 premium are sometimes the same hardware with a different control panel — the point we work through in Midea vs Frigidaire. It also makes one check worth two minutes: a 2023 CPSC recall covered roughly 1.56 million Midea-built units sold under more than two dozen brand names for a fire hazard. Verify the model and date code against the CPSC list before buying anything used, clearance, or pulled out of a garage.
The lineup, tier by tier
Capacities are DOE 2019 ratings at 65 °F and 60% RH. Prices are typical street bands that move with sales — a shape, not a quote.
| Tier | Rated capacity | Tank | Drainage | Typical price |
|---|---|---|---|---|
| 20-pint portable | 20/day (old 30-pint) | 1.6 gal (13 pt) | Bucket or gravity | $170–210 |
| 35-pint portable | 35/day (old 50-pint) | 1.6 gal (13 pt) | Bucket or gravity | $190–250 |
| 50-pint portable | 50/day (old 70-pint) | 1.6 gal (13 pt) | Bucket or gravity | $220–290 |
| 50-pint, built-in pump | 50/day | 1.6 gal (13 pt) | Uphill to sink or window | $260–340 |
| Cube (expandable tank) | 20–50/day by model | ≈2× a standard bucket | Tank, gravity, pump on upper models | $320–400 |
Read that table by column. Capacity is the only column that changes how fast the room dries; drainage decides whether you're still using the machine in week three. Wi-Fi sits across the middle and upper tiers, adding scheduling and a humidity readout on your phone — useful in a basement you rarely visit, worth nothing to the coil. What the app does and doesn't do is in the smart dehumidifier guide.
Which tier fits your situation
Start from the EPA's target range for indoor humidity — 30–50%, with 60% as the line where mold growth gets comfortable — and put a hygrometer in the room for two days before buying anything. A steady 55–60% RH is a moderate problem; 70%+ with damp on the slab is a wet one, and wet spaces need the tier above what square footage alone suggests.
- Under 500 sq ft, mildly damp (bedroom, office, small apartment): the 20-pint tier. Check the dB figure if it shares a room with a sleeper — 45–52 dBA is the usual band, the whole argument in our bedroom writeup.
- 500–1,500 sq ft, damp to wet (most basements): the 50-pint, on a hose, humidistat at 50%. The 35-pint is the in-between pick for a dry-ish basement.
- Drain is above the unit — laundry sink, window well, floor drain across the room: the pump model. A hose that has to climb four inches is a hose that backs up.
- Below 65 °F (unheated garage, crawl space): a compressor loses output as the coil cools and starts spending the hour defrosting instead of drying. Confirm auto-defrost and a stated low-temp limit, or read desiccant vs compressor first.
Sizing deserves a chart, not a guess — square footage and current RH both feed the pint number, and our sizing guide lays out the grid.
Common mistakes
- Running a 50-pint on the bucket. Near its rating it fills the 13-pint tank in about six hours, shuts off on full, and the room climbs back past 60% RH while you're at work. Fit the hose on day one.
- Comparing the new rating to an old one. A 50-pint Midea against a pre-2019 70-pint is the same machine on two scales. Check that both numbers come from the DOE 65 °F test.
- Buying used or clearance without the recall check. The 2023 CPSC action covered about 1.56 million Midea-built units across many brand names. Look up the model and date code before money changes hands.
- Paying for Wi-Fi and skipping the pump. The app changes how you set the humidistat; the pump changes whether the machine runs unattended for a week. If the budget stretches to one, it's the pump.
FAQ
What size Midea dehumidifier do I need?
For most basements between 500 and 1,500 sq ft, the 50-pint tier on the DOE 2019 scale is the right call — it's the old 70-pint class. Rooms under 500 sq ft reading 55–60% RH are fine on the 20-pint. Run square footage and measured humidity through our sizing guide before you order.
Do Midea dehumidifiers have a built-in pump?
Some do, generally at the top of the 50-pint tier and on upper Cube configurations, for roughly $40–60 over the gravity-drain version. Without a pump you get a hose port that only drains downhill. If your nearest drain is a laundry sink four feet up, the pump isn't an upgrade — see where to place a dehumidifier.
Is the Midea Cube worth the extra money?
Only if you're stuck emptying a tank. The Cube's body extends to hold roughly twice a standard 1.6-gallon bucket, turning two trips a day into one — but it costs $80–120 more than a plain 50-pint and dries no faster. If you can run a hose to a floor drain, a standard unit plus $8 of tubing does the same job.
Why is my Midea dehumidifier not collecting water?
Below about 65 °F a compressor collects far less, and under 41 °F it can frost over and spend the cycle defrosting. Check too that the humidistat isn't already satisfied — at a 50% setpoint in a 48% room it idles by design. Work the list in dehumidifier not collecting water before assuming a fault.
