The Midea 50-Pint Dehumidifier with Pump is the best quiet dehumidifier for most basements. It combines a published noise level as low as 47 dBA with substantial moisture-removal capacity, automatic humidity control and a built-in pump that can send collected water to an elevated drain.
The Honeywell TPFIT50PWK is a strong alternative with a 51 dBA published sound rating, three fan speeds and its own built-in pump. For basements without permanent drainage, the Midea Cube 50-Pint with Pump provides an unusually large water reservoir. The Waykar 80-Pint Dehumidifier offers more advertised capacity for large or persistently damp spaces.
No full-size compressor dehumidifier is silent. However, choosing the right capacity, fan speed and drainage method can prevent the machine from becoming an unnecessary source of constant noise.

1. Midea 50-Pint Dehumidifier with Pump — Best Overall
The Midea 50-Pint Dehumidifier with Pump is the most balanced option for a typical residential basement. It delivers the capacity needed for persistent moisture while addressing one of the most common basement problems: the lack of a conveniently positioned floor drain.
Midea lists its quieter operating level at 47 dBA. Although it will become louder at higher fan speeds, that minimum rating is competitive for a full-size compressor dehumidifier.
The built-in pump can move collected water vertically or horizontally to a suitable drain, sink or window outlet. That gives it an important advantage over gravity-drain-only models.
Key specifications
- 50-pint daily moisture-removal capacity
- Published operation as low as 47 dBA
- Built-in condensate pump
- Continuous gravity-drain connection
- Adjustable humidity setting from 35% to 85%
- Automatic defrost
- Automatic restart
- Full-bucket protection
- Washable filter
- Caster wheels
Why it is the best overall basement choice
A 50-pint machine provides enough capacity for many medium-to-large basements without moving into commercial restoration equipment. It can handle ordinary seasonal humidity, musty conditions and moisture created by activities such as drying laundry downstairs.
The integrated pump also allows the unit to operate without someone carrying a heavy water bucket upstairs every day. This can be especially valuable during humid summer weather, when a basement dehumidifier may collect several gallons of water.
When a gravity drain is available, the pump does not have to be used. A properly sloped gravity hose is typically the simplest and quietest drainage method.
What it sounds like
The 47 dBA specification represents the quieter end of its operation. During initial drying, the higher fan setting and active compressor will be more noticeable.
The sound is primarily a combination of steady airflow and compressor hum. Short periods of additional mechanical noise can occur when the built-in pump activates.
A finished basement used as a family room or office will not be silent while the machine runs. However, positioning it away from seating and using the lower fan setting after humidity stabilizes should make it less intrusive.
Pros
- Competitive published noise rating
- Strong 50-pint moisture removal
- Built-in pump
- Gravity-drain option
- Adjustable humidistat
- Suitable for large residential basements
- Automatic restart after a power interruption
Cons
- Pump operation creates occasional additional noise
- More expensive than basic gravity-drain models
- Full-size design requires adequate clearance
- Still clearly audible when operating on high
Best for: Most finished or unfinished basements, especially those without a conveniently located floor drain.

2. Honeywell TPFIT50PWK — Best Pump-Equipped Alternative
The Honeywell TPFIT50PWK is another strong basement dehumidifier with a built-in pump. It replaces the older Honeywell model previously discussed in this guide and is the exact model linked below.
Honeywell specifies a 51 dBA sound level for the TPFIT50PWK. It is slightly louder on paper than the Midea’s lowest published setting, but it remains within a reasonable range for a high-capacity portable dehumidifier.
Its three fan speeds provide more control over the balance between noise and moisture removal. High speed can be used to bring a damp basement under control, while low speed is more appropriate for routine maintenance.
Key specifications
- Model: TPFIT50PWK
- 50-pint daily moisture-removal capacity
- Published 51 dBA sound level
- Three fan speeds
- Built-in automatic drain pump
- Continuous gravity drainage
- Approximately 14-pint water tank
- Laundry mode
- Automatic comfort mode
- Automatic defrost
- Automatic restart
- Washable filter
- ENERGY STAR certified
- Operating-temperature range beginning at approximately 41°F
- Advertised coverage up to 4,000 square feet
Why it works well in a basement
The Honeywell provides three ways to manage collected water:
- Empty the removable bucket manually
- Connect a hose to a lower gravity drain
- Use the pump to move water to an elevated outlet
This flexibility allows the unit to work in basements with very different layouts.
Its automatic defrost system is also important in cooler conditions. A standard compressor dehumidifier becomes less effective as the room temperature drops, and frost can develop on the coils. Automatic defrost pauses normal moisture removal when necessary so the accumulated frost can melt.
The 41°F minimum operating temperature does not mean it will remove the same amount of water at 41°F as it does under warmer test conditions. All refrigerant dehumidifiers lose moisture-removal performance in colder air.
Laundry mode
Laundry mode is useful when wet clothing is hung in the basement. It runs the unit more aggressively to address the temporary increase in moisture.
This setting will also create more noise and consume more electricity than ordinary humidity-controlled operation. It is best used temporarily rather than as the default operating mode.
Pros
- Built-in pump
- Three fan speeds
- Published 51 dBA sound rating
- 50-pint capacity
- Automatic defrost
- Laundry mode
- ENERGY STAR certified
- Gravity-drain capability
- Washable filter
Cons
- Slightly louder published rating than the Midea’s lowest setting
- Pump-equipped design may cost more
- Laundry mode increases noise and energy consumption
- The 14-pint bucket may fill quickly in a very wet basement
Best for: Basements that need a pump-equipped 50-pint machine with three fan speeds and a dedicated laundry setting.

3. Midea Cube 50-Pint Dehumidifier with Pump — Best Large Water Tank
The Midea Cube 50-Pint Dehumidifier with Pump uses a two-piece design instead of a conventional pull-out bucket.
The dehumidifier section sits above a large reservoir capable of holding considerably more water than the bucket in a typical portable unit. When not in use, the upper section can nest inside the reservoir to reduce its storage height.
The current model also includes a built-in pump, gravity-drain capability, Wi-Fi controls and compatibility with Alexa.
Key specifications
- 50-pint daily moisture-removal capacity
- Advertised coverage up to 4,500 square feet
- Large-capacity reservoir
- Built-in pump
- Continuous gravity-drain connection
- Wi-Fi control
- Alexa compatibility
- Adjustable humidity control
- Automatic restart
- Automatic defrost
- Nesting storage design
Why it works well without permanent drainage
A conventional 50-pint dehumidifier may collect far more water in a day than its internal bucket can hold. That means the machine could shut off several times unless it is connected to a drain.
The Cube’s larger reservoir allows it to continue operating longer between manual emptying sessions. It is a practical solution for a basement without a floor drain when the owner does not want to use the pump permanently.
The adjustable fill-level control can stop collection before the reservoir reaches maximum capacity. This makes the tank lighter and easier to carry.
Noise performance
The current Amazon listing describes the Cube as suitable for quiet basement operation but does not provide a clearly standardized dBA figure for this exact model.
Previous versions of the 50-pint Cube have performed competitively in independent sound tests, but those measurements should not be presented as guaranteed results for every current Cube variation. Fan speed, compressor cycling, distance and room acoustics can all change the recorded level.
The Cube is included because it balances basement capacity, flexible drainage and longer unattended bucket operation—not because it has the lowest verified sound rating in this comparison.
Smart controls
The Midea Air app can be used to:
- View the reported basement humidity
- Change the target humidity
- Select operating modes
- Monitor the reservoir
- Adjust the desired fill level
- Control the unit without walking downstairs
The app is useful but not required for basic operation.
Pros
- Large water reservoir
- Built-in pump
- Gravity drainage
- 50-pint capacity
- Remote monitoring
- Adjustable fill level
- Compact nesting design for storage
Cons
- No clearly standardized dBA rating for this exact listing
- A full reservoir can be very heavy
- Two-piece design is less conventional
- Smart features add setup complexity
- Compressor and pump remain audible
Best for: Basements without permanent drainage where a larger water reservoir and remote monitoring are valuable.

4. Waykar 80-Pint Dehumidifier — Best for a Large Basement with a Floor Drain
The Waykar 80-Pint Dehumidifier is the higher-capacity option in this comparison. It is intended for large basements and spaces with persistent moisture loads.
Its Amazon listing specifies operation at approximately 40 dBA on low and no more than 55 dBA at maximum output. These are manufacturer-provided figures rather than results from a standardized independent comparison.
Even so, the availability of a low fan setting can be helpful in a finished basement. The higher setting can be used during initial drying, after heavy rainfall or while drying laundry. Low speed can then maintain the selected humidity with less fan noise.
Key specifications
- Advertised 80-pint capacity
- Published 40 dBA low setting
- Published maximum of 55 dBA
- Automatic comfort mode
- Continuous gravity drainage
- Removable water tank
- Automatic defrost
- Automatic restart
- Adjustable humidity control
- Washable filter
- Caster wheels
- Operation advertised down to approximately 42°F
Important capacity-rating warning
Dehumidifier capacity can be confusing because older and newer testing standards produce different pint ratings for machines with similar hardware.
The current Department of Energy procedure tests portable dehumidifiers at 65°F and 60% relative humidity. Older ratings were commonly produced under warmer conditions that allowed the same machine to collect more water.
Because the Waykar is advertised as an 80-pint model, buyers should confirm which test condition applies before directly comparing that number with a current DOE-rated 50-pint model.
The Waykar is still positioned as the high-capacity option in this article, but the advertised number should not be treated as a perfect apples-to-apples measurement without confirming the underlying test standard.
Drainage requirements
The Waykar supports continuous hose drainage but does not include the same integrated upward-drain pump provided by the two Midea models and the Honeywell.
The drainage hose must maintain a downward slope for its entire route. Suitable destinations include:
- A floor drain
- A lower utility-drain connection
- A sump-pump basin, where permitted
- Another approved outlet positioned below the dehumidifier
A gravity hose cannot carry water uphill into a utility sink.
Pros
- Higher advertised capacity
- Low fan setting
- Published operating range of 40 to 55 dBA
- Automatic comfort mode
- Continuous gravity drainage
- Automatic defrost
- Suitable for large open basements
Cons
- No built-in pump
- Advertised capacity may use a different rating basis
- Manufacturer-provided noise claims are not standardized
- Excessive capacity for a small, mildly damp basement
- Requires a properly positioned gravity drain for unattended use
Best for: Large or persistently damp basements with access to a floor drain.

Which Quiet Basement Dehumidifier Should You Buy?
Choose the Midea 50-Pint with Pump if you want the best overall balance of quiet operation, moisture removal and drainage flexibility.
Choose the Honeywell TPFIT50PWK if you want a comparable pump-equipped machine with three fan speeds, laundry mode and automatic comfort control.
Choose the Midea Cube 50-Pint with Pump if you may rely on the bucket and want to empty it less frequently.
Choose the Waykar 80-Pint if you have a large, persistently damp basement and an appropriate gravity drain.
If you are uncertain about capacity or electricity usage, use the Dehumidifier Size and Operating-Cost Calculator before choosing a model.
How We Selected These Basement Dehumidifiers
These recommendations are based on published specifications, drainage configurations, current Amazon listings, capacity, basement suitability and available noise information.
QuietTechReport did not physically measure every model in the same test room. Manufacturer ratings and independent measurements are identified separately because results collected at different distances and fan speeds cannot be compared as though they came from one standardized test.
Each selected product provides:
- Compressor-based moisture removal
- Capacity suitable for significant basement humidity
- A humidistat
- Continuous drainage
- Automatic defrost
- Automatic restart
- At least one lower-noise operating option
- A specific Amazon product listing
Small thermoelectric dehumidifiers were excluded. Although these products can operate more quietly, most do not remove enough water to manage a damp basement.
How Quiet Is a Quiet Basement Dehumidifier?
A full-size compressor dehumidifier operating in the upper 40s or low 50s dBA is relatively quiet for its category. You will still hear it when standing nearby.
The sound generally contains three components:
Fan noise
Fan noise is usually steady and broadband. A lower fan speed reduces this portion of the sound, although it also moves less air across the coils.
Compressor noise
The compressor creates a deeper mechanical hum. It cycles according to the humidity setting and may briefly become more noticeable when starting.
Vibration
Vibration can travel through a hard basement floor, wall or nearby shelving. In some homes, this structure-borne sound is more noticeable upstairs than the airborne fan noise is inside the basement.
Noise measurements can change substantially based on distance. A reading taken immediately above the exhaust should not be compared directly with one recorded 10 feet away.
Our dehumidifier noise comparison explains these differences in more detail.
What Size Dehumidifier Does a Basement Need?
Dehumidifier capacity is measured in pints of water removed during 24 hours. The required capacity depends on both the basement’s size and its condition without dehumidification.
| Basement Condition | Suggested Starting Capacity |
|---|---|
| Small and occasionally damp | 20 to 35 pints |
| Medium and regularly damp | 35 to 50 pints |
| Large or very damp | 50 pints |
| Exceptionally large or persistently wet | Higher-capacity portable or whole-basement system |
A basement with visible condensation, damp concrete, musty odors or humidity consistently above 60% requires more capacity than a similarly sized space with mild seasonal humidity.
Other factors that increase the moisture load include:
- Wet laundry
- An unsealed dirt crawlspace
- Exterior water intrusion
- Open basement windows during humid weather
- Plumbing leaks
- Poor gutter or downspout drainage
- Air leaks around rim joists
- Multiple basement rooms with closed doors
ENERGY STAR advises that it is usually better to slightly oversize a portable dehumidifier than to undersize it. An undersized unit can run continuously without reaching the target humidity, resulting in more noise and disappointing moisture control.
Current and Older Pint Ratings Are Different
Portable dehumidifier ratings changed when the Department of Energy adopted a test procedure based on cooler conditions.
Current models are tested at approximately 65°F rather than the warmer conditions used for many older ratings. This provides a more realistic indication of performance in a basement but produces a lower pint number.
As a result, an older model advertised as 70 pints may be comparable to a current 50-pint machine.
Before comparing capacities, determine whether both products use the same testing standard. Coverage claims such as “up to 4,500 square feet” are also less useful than the rated pint capacity and the actual moisture conditions in the basement.
Do You Need a Basement Dehumidifier with a Pump?
Choose a built-in pump when the available drainage destination is higher than the dehumidifier’s drain outlet.
A pump is particularly useful when:
- Water must drain into a utility sink
- The hose must reach a basement window
- No floor drain is available
- The machine cannot be raised above the drain
- You do not want to empty a bucket manually
A pump is unnecessary when a hose can run continuously downhill to a suitable drain.
Gravity drainage has several advantages:
- Fewer mechanical components
- No pump cycling noise
- Less risk of pump failure
- Simpler hose installation
- No energy required to move the water
If your basement has a floor drain in a practical location, a gravity-drain model may provide everything you need. If it does not, buying a pump-equipped model is usually preferable to adding a separate external condensate pump later.
Our gravity drain vs. built-in pump guide shows how to assess the entire hose route, including thresholds and low spots that can make an apparently convenient floor drain impractical.
If your drainage destination is above the dehumidifier, compare our best dehumidifiers with a built-in pump for three residential models that can send water to a utility sink, standpipe or other elevated outlet.
Best Humidity Setting for a Basement
Set the dehumidifier to 50% relative humidity initially. This is an appropriate target for many residential basements.
If the room still smells musty or a separate hygrometer reports higher readings elsewhere in the basement, reduce the setting to 45%.
A 35% setting is rarely necessary for ordinary basement moisture control. It can make the compressor run longer, increasing noise and electricity consumption.
The sensor inside a dehumidifier measures the air near the machine. It may not represent the humidity in a distant corner or closed room. A separate digital hygrometer can help identify uneven conditions.
If the unit remains audible after reaching its target, the fan may still be running while the compressor has stopped. Use our dehumidifier fan vs. compressor troubleshooting guide to check normal operation, settings and possible faults.
How to Make a Basement Dehumidifier Quieter
Use high speed only when necessary
Run the higher fan setting when initially drying the basement. Switch to low after reaching the target humidity.
Keep the machine away from corners
Corners and nearby walls reflect sound into the room. Follow the manufacturer’s clearance requirements and direct the exhaust toward open space.
Use a firm, level surface
An uneven concrete floor can cause the cabinet or bucket to vibrate. Move the machine until every caster rests securely on the floor.
Add vibration isolation carefully
A dense rubber appliance mat can reduce vibration transmitted through the floor. The mat must remain flat and must not block an intake, drain opening or caster.
Use continuous drainage
Continuous drainage prevents full-bucket shutdowns and reduces the amount of water that must be handled manually.
Clean the filter
Restricted airflow can reduce moisture removal and extend runtime. Inspect and clean the washable filter according to the manufacturer’s instructions.
Close basement windows
Opening a basement window during humid weather continuously introduces more moisture. The dehumidifier then runs longer while accomplishing less.
Address water intrusion
A portable dehumidifier cannot permanently solve:
- Foundation leaks
- Plumbing leaks
- Sewer backups
- Recurring flooding
- Poor exterior grading
- Missing or damaged gutters
- Downspouts that discharge beside the foundation
Correct the water source instead of relying on a dehumidifier to conceal it.

Portable Dehumidifier or Whole-Basement System?
A portable 50-pint dehumidifier is sufficient for many open residential basements. A whole-home or ducted dehumidifier may be more appropriate when:
- The basement contains several separate rooms
- Humidity affects multiple floors
- A portable unit runs continuously
- The space is exceptionally large
- Even lower perceived noise is important
- More uniform humidity control is required
A ducted system costs substantially more and normally requires professional installation. However, it can locate the mechanical equipment away from occupied areas and distribute treated air more evenly.

Frequently Asked Questions
What is the best quiet dehumidifier for a basement?
The Midea 50-Pint Dehumidifier with Pump is the best overall choice. It provides 50-pint capacity, operation as low as 47 dBA and three drainage methods.
Which basement dehumidifier has the lowest advertised noise level?
The Waykar advertises 40 dBA operation on low. However, noise figures from different manufacturers may use different measurement distances and test methods. The lowest advertised number does not guarantee the lowest result in an independent side-by-side test.
Is 50 dBA quiet for a dehumidifier?
Approximately 50 dBA is relatively quiet for a full-size compressor dehumidifier. It will remain audible nearby but should be less intrusive than models that reach the 60-to-70-dBA range.
Is a 50-pint dehumidifier enough for a basement?
A 50-pint model is sufficient for many medium-to-large residential basements. Severe water intrusion, extremely large spaces or multiple closed rooms may require additional capacity or a ducted system.
Can I run a basement dehumidifier continuously?
Modern dehumidifiers can operate for extended periods when connected to continuous drainage. The humidistat should cycle the compressor after the selected humidity level is reached.
If the unit runs continuously without lowering humidity, it may be undersized or attempting to manage an unresolved moisture source.
Should I buy a dehumidifier with a pump?
Buy a pump-equipped model if water must travel uphill to reach a sink, window or drain. A pump is unnecessary when a hose can run continuously downhill to a floor drain.
Can I put the dehumidifier beside a sump pump?
A dehumidifier can often drain into a sump basin, provided the setup is permitted, secure and does not interfere with the sump system. Position the hose so it cannot become dislodged or create a tripping hazard.
Why does my dehumidifier make the basement warmer?
A compressor dehumidifier releases heat as it removes water from the air. A slight temperature increase is normal and may be more noticeable in a small or enclosed basement.
What temperature is too cold for a portable dehumidifier?
Many residential compressor models are rated to operate down to approximately 41°F. Moisture removal still declines as the temperature falls. A desiccant or purpose-built low-temperature system may be more effective in consistently cold conditions.
If your basement stays cold, compare desiccant and compressor dehumidifiers for low-temperature use before choosing a model.
Can one dehumidifier control several basement rooms?
It may work when doors remain open and air circulates freely. Closed rooms can retain moisture even after the central area reaches the selected target. Additional air circulation, another dehumidifier or a ducted system may be necessary.
QuietTechReport’s Results
The Midea 50-Pint Dehumidifier with Pump is the best quiet dehumidifier for most basements. Its 47 dBA minimum published noise level, 50-pint capacity and flexible drainage system address the features that matter most below grade.
The Honeywell TPFIT50PWK is the strongest alternative for buyers who want a pump, three fan speeds and a laundry mode. The Midea Cube 50-Pint with Pump is better for situations where a large reservoir and smart monitoring are priorities.
For a particularly large or damp basement with an accessible floor drain, the Waykar 80-Pint Dehumidifier provides greater advertised capacity and a 40 dBA low setting.
Regardless of which model you choose, correct sizing, a realistic humidity target and dependable continuous drainage will reduce runtime, noise and the amount of maintenance required.
