That heavy, musty smell in your basement is not just annoying. It is water in the air telling you the space is out of control.
Midea Cube 50-Pint MAD50PS1WT — Top Pick
It nails the trifecta: whole-basement coverage up to 4,500 sq ft, a huge collapsible tank so you rarely empty it, and quiet, efficient operation you can run under a bedroom. Set the humidistat and let it kill the damp for good.
In a hurry? That's our pick. Want the reasoning and the full comparison? Keep reading.
You walk down to the basement and it hits you: damp air, a faint musty smell, maybe a cardboard box that feels soft to the touch. Your stuff is slowly losing the battle to moisture, and a small plug-in unit from the hardware store is not going to win it back. A big space needs a big machine.
A large dehumidifier pulls serious water out of the air, day after day, so mold never gets a foothold and that smell finally disappears. In this guide you will learn how pint ratings map to real square footage, why a built-in pump changes everything for continuous drainage, and which four models we would actually put in our own basements right now.
Key Takeaways
- Match the pint rating to your space: 50-pint units handle whole basements up to roughly 4,500 sq ft, while 35-pint models fit medium rooms.
- A built-in pump lets you drain water uphill into a sink continuously, so you never empty a bucket again.
- Bigger tank plus an auto-humidistat means the machine runs only when needed and rarely overflows.
- Quiet, efficient units cost less to run and won't drone through your whole house.
- Our top pick is the Midea Cube 50-Pint for its efficiency, quiet operation, and huge collapsible tank.
How to Read Pint Ratings and Coverage (Without the Confusion)
Dehumidifiers get labeled by pints per day: 35-pint, 50-pint, and so on. That number tells you how much water the machine can pull from the air in 24 hours under test conditions. Bigger pint numbers move more moisture, which matters when a whole basement is damp. But the pint rating alone doesn't tell you if the unit fits your room, so you also need to look at the coverage in square feet.
Here is the simple rule. A 50-pint unit rated for up to 4,500 square feet is built to dry a full basement or a large open floor. A 35-pint model suits a medium room, a finished den, or a smaller cellar. If your space is genuinely damp, sizing up rather than down pays off: the machine reaches your target humidity faster and then coasts instead of straining. An undersized unit runs constantly, never quite wins, and burns more power doing it.
Aim to hold your basement between 45 and 50 percent relative humidity. That range starves mold and dust mites without drying the air so much it feels harsh. An auto-humidistat handles this for you: you set the target, and the machine switches itself on and off to stay there.
Pumps, Hoses, and Tanks: How You Actually Get the Water Out
Every dehumidifier collects water somewhere, and how you empty it decides whether you love the machine or resent it. You have three options: the bucket, a gravity drain hose, or a built-in pump. The bucket is fine for a small room you visit often, but on a large 50-pint unit in a wet basement, you could be emptying it more than once a day. That gets old fast.
A gravity drain hose is the next step up. You snap a hose onto the unit and route it to a floor drain, and water flows out continuously as long as the drain sits lower than the outlet. No emptying, no overflow. The catch: you need a drain below the machine, which not every basement has.
A built-in pump is the real freedom upgrade. It pushes water uphill and across the room, so you can drain into a laundry sink or out a window even when there is no floor drain nearby. Set it and forget it for weeks. If your basement lacks a low drain, a pump like the one in the hOmeLabs unit is worth every dollar. Pair any of these with a large tank and an auto-humidistat, and the machine basically runs itself.
Noise and Efficiency: The Difference You Live With Daily
A dehumidifier that runs most of the day needs to be quiet and efficient, or you will notice it in both your ears and your power bill. Efficiency is measured by how many pints the unit removes per unit of energy: a more efficient machine hits your humidity target and then rests, sipping power instead of guzzling it. Over a humid summer, that gap adds up to real money.
Noise matters more than people expect, especially if your basement sits under a bedroom or a home office. The Midea Cube models stand out here because they run genuinely quietly for their size, so the low hum fades into the background instead of droning through the floor above. If a family room or guest space shares walls with the unit, quiet operation moves from nice-to-have to must-have.

1. Midea Cube 50-Pint — Best Overall
Midea Cube 50-Pint MAD50PS1WT
The Midea Cube is the one we would carry down our own basement stairs first. Its clever design collapses for storage and expands into a huge water tank, so you empty it far less often than a normal 50-pint unit. When you do want hands-off drainage, snap on a hose and let gravity do the work. It covers up to 4,500 square feet, which is enough for most whole basements.
What seals it as our top pick is how quietly and efficiently it runs. For a machine this powerful, the noise stays low enough to sit under a bedroom without complaints, and the efficiency keeps summer running costs down. Set the humidistat, walk away, and let it hold your basement at a healthy 45 to 50 percent. It is the best overall choice for drying a large, musty space.
Pros
- Excellent efficiency keeps running costs low
- Runs very quietly for its size
- Huge collapsible tank means fewer empties
- Covers up to 4,500 sq ft
- Accurate auto-humidistat set-and-forget
Cons
- Premium price versus budget units
- No built-in pump (gravity hose only)
- Large footprint when expanded
2. hOmeLabs 50-Pint — Best Budget Large
hOmeLabs 4,500 Sq Ft 50-Pint Dehumidifier
If your basement has no floor drain, the hOmeLabs 50-pint solves that problem out of the box with a built-in pump. Instead of relying on gravity, the pump pushes water up and out to a sink or a window, so you get truly continuous drainage without ever touching a bucket. For a large space that stays wet, that convenience is hard to beat at this price.
This is our best budget large pick because you get serious 4,500-square-foot coverage plus that pump for less than many premium models cost. It runs at a moderate noise level rather than whisper-quiet, so it fits an unfinished basement better than a room under a nursery. For most people fighting real dampness on a budget, it delivers where it counts.
Pros
- Built-in pump for continuous, uphill drainage
- Strong 4,500 sq ft coverage
- Great value for the features
- Auto-humidistat holds your target
- Auto-defrost for cooler basements
Cons
- Louder than the Midea Cube models
- Bulkier design
- Tank smaller if you skip the pump
3. Frigidaire FGAC5045W1 — Best Smart-Home
Frigidaire FGAC5045W1
The Frigidaire FGAC5045W1 is the pick for anyone who already runs a connected home. It ships with WiFi and works with Alexa and Google Assistant, so you can check your basement humidity from your phone or ask a speaker to bump the setting without going downstairs. A built-in ionizer adds a freshening step that helps knock down that musty basement air.
Under the smart features sits a capable 50-pint machine that dries large rooms and drains through a hose for hands-off operation. Noise sits at a moderate level, which is fine for a basement or utility area. If you value dashboards, voice control, and remote monitoring as much as raw water removal, this is your best smart-home choice.
Pros
- WiFi with Alexa and Google Assistant
- Built-in ionizer for fresher air
- Remote monitoring from your phone
- Solid 50-pint water removal
- Continuous drainage via hose
Cons
- Smart features add to the price
- Not as quiet as the Midea Cube
- App setup takes a few minutes
4. Midea Cube 35-Pint — Best Mid-Size
Midea Cube 35-Pint Dehumidifier
Not every damp space is a cavernous basement. If you are drying a finished den, a medium cellar, or a single problem room, the Midea Cube 35-Pint gives you the same smart, collapsible design in a right-sized package. You get the huge expandable tank and the option of hose drainage, just tuned for a smaller footprint and a lower price than the 50-pint version.
It runs just as quietly as its bigger sibling, which makes it a great fit for rooms you actually spend time in. Match it to a medium space and it holds your humidity target with ease while staying out of your way. This is the best mid-size choice when a full 50-pint machine would be overkill.
Pros
- Perfectly sized for medium rooms
- Very quiet operation
- Collapsible tank saves space
- Efficient, low running cost
- Hose option for hands-off draining
Cons
- Not enough for a whole large basement
- No built-in pump
- Smaller water capacity than 50-pint

For a full basement up to about 4,500 square feet, choose a 50-pint unit like the Midea Cube 50-Pint or the hOmeLabs 50-Pint. For a medium room, a 35-pint model is plenty. When a space is clearly damp, sizing up helps the machine hit your target faster and then rest.
You need one if your basement has no floor drain below the unit. A pump pushes water uphill into a sink or out a window for continuous drainage, so you never empty a bucket. If you do have a low drain nearby, a gravity hose works fine and costs less.
Those past recalls involved older Gree-made units sold roughly between 2011 and 2014. The current models in this guide are not affected by those recalls. As with any appliance, plug it straight into a wall outlet rather than an extension cord and keep the vents clear.
Aim for 45 to 50 percent relative humidity. That range keeps mold and dust mites from thriving without over-drying the air. An auto-humidistat lets you set the target once, then the machine cycles itself on and off to hold it steady.
Noise varies by model. The Midea Cube 50-Pint and 35-Pint run very quietly for their size, which matters if the unit sits under a bedroom or office. The hOmeLabs and Frigidaire units run at a moderate level that suits an unfinished basement or utility area.
