Best Dehumidifier for Basement Reviews
1. Overall Best Pick: Vremi 4,500 Sq. Ft.
- Our Vremi dehumidifier is rated to remove 50 pints (70 Pint 2012 DOE Rating Standard) of moisture per day, and is ideal for medium to large spaces from 3,000 square feet up to 4,500 square feet
- We designed our dehumidifier with convenience and style in mind. This dehumidifier sports a sleek, clean look with convenient built-in wheels and handles, and a quiet fan that does its job without too...
- It's a dehumidifier, not a rocket ship, and our user-friendly features reflect this. Simply adjust the appliance to your ideal moisture setting, let it run its continuous 24-hour cycle until the tank...
This compressor-type dehumidifier from Vremi is our top pick. Vremi is a relatively new but reputable name in the home appliances industry.
The first thing to consider about this model is its capacity. According to the manufacturer, the Moisture Maniac can remove 50 pints of moisture per day, and it can dehumidify rooms with floor sizes of up to 4,500 square feet. For areas with humidity levels between 50 and 65 percent, this model’s capacity is ideal.
The Moisture Maniac offers a wide range of high-end features to make your life as a homeowner easier. The most prominent feature this portable dehumidifier offers is its continuous mode.
In this mode, the unit synchronizes operation with external drainage so that it can run continuously without having to switch off.
When you switch your unit on for the first time, the continuous mode will be on by default, and you won’t be able to adjust the humidity manually. To do so, you first have to switch continuous mode off.
The Moisture Maniac also features a turbo mode that increases the fan speed and moisture removal. If you recently had a water heater burst or flood in your basement, this feature is ideal for getting rid of excess moisture in the air quickly. This unit is relatively loud on turbo mode, however, and is not suitable as a set-and-forget option.
Because the Moisture Maniac is a compressor dehumidifier, it is susceptible to frost accumulation. Fortunately, the unit features an automatic defrost mode that switches off the compressor while keeping the fan running to melt the ice.
According to the product specifications, the Moisture Maniac has a water tank with a capacity of about 14.8 pints. At maximum capacity, you have to empty the collection tank three or four times per day. You can also connect a garden hose with a length of at least three feet to the unit for continuous gravity drainage—that way, you don’t have to watch the water levels.
- Certification from the Environmental Protection Agency (EPA)
- Wheels and handle for easy portability
- One-year manufacturer’s warranty from Vremi
- Gravity drainage eliminates the need to check water levels
- Capacity to dehumidify most residential basements
- Defrost mode to increase the operating temperature range
- Reasonable price
- A relatively loud noise level
- Requires regular cleaning
2. Best Runner Up: Waykar 4,500 Sq. Ft.

- INTELLIGENT TOUCH CONTROL- There is an intelligent screen touch control panel display on the dehumidifier, you can operate it easily. Humidity Auto Control: Simply adjust to your ideal moisture...
Our runner up in this review guide is the 70-pint dehumidifier from Waykar. This high-performing unit can handle basements with a floor area of up to 4,500 sq. ft. and is suitable for high humidity levels of up to 85 percent. If you have severe moisture issues in a large basement, this unit is one of your most viable options.
It also offers several features to ensure the best possible performance, functionality, and user convenience.
One of the handiest features is automatic humidity control. All you have to do is select a comfortable humidity level using the intelligent touch screen panel. The unit will automatically monitor humidity levels in the room and adjust its performance accordingly to maintain the level you selected.
To protect the compressor against frost build-up, it features an auto-frost censoring feature that kicks in and shuts down the machine.
When the water container is full, the unit will also automatically shut down, and the alert indicator will light up. You can, however, prevent unnecessary downtime by connecting the 6.56-foot drain hose for continuous draining. The gravity draining feature also eliminates the need to check the water level regularly.
We saved the best feature for last. In addition to extracting excess moisture from the air, this model also purifies the air. The purification system removes airborne pollutants such as dust particles, pollen, and unpleasant odors to enhance optimal comfort levels and a healthy environment.
- High dehumidification capacity
- One-year manufacturer’s warranty, two-year extended warranty
- Child lock and safety standby mode to prevent overheating
- Auto shut-off when the water bucket is full
- Automatic humidity control for added convenience
- Air purification feature to remove unwanted airborne pollutants
- Not compatible with standard garden hose sizes
- The included hose may be too short
- Relatively high price tag compared to others with this capacity
3. Aprilaire 1830 Pro 3,800 Sq. Ft.
- BUILT TO LAST with corrosion-resistant aluminum coils, Aprilaire Dehumidifiers are designed and manufactured in the U.S.A. by Aprilaire, the leader in indoor air quality solutions
- MINIMIZE AIRBORNE VIRUS SURVIVAL rates by keeping relative humidity below 60% with a dehumidifier
- REDUCES & CONTROLS BASEMENT & WHOLE HOME HUMIDITY to help prevent damp carpeting and furnishings, mold, mildew, and odors, and mold, termites, structural wood rot, and odors in a sealed crawl space
The 1830 Pro is a top-selling dehumidifier from Aprilaire that is relatively basic in terms of functionality. However, despite its simplicity, it has a high dehumidification capacity of 70 pints of moisture per day, and it can cover up to 3,800 sq. ft. So, if you have a 60 x 60-foot basement with a humidity level of, say, 70 percent, this unit will be sufficient.
This compressor dehumidifier has high-quality construction to ensure the best durability and a long lifespan. The aluminum coils are corrosion-resistant, and the unit has a relatively low maintenance requirement. You only have to check the filter once per year, and the cleaning process is quick and easy.
A unique aspect of the 70-pint 1830 Pro is that it doesn’t have a water collection tank. You have to connect a hose or place the unit over a floor drain for continuous gravity drainage.
Because there is no container, the unit is relatively compact, and provides you with ample installation flexibility, especially in restricted crawl spaces. You also don’t have to check the water levels, and there are no unnecessary downtimes as the result of a full collection tank.
Adding to the unit’s flexibility and easy access is the ability to mount the control panel in more than one way—on the side or top. The interactive display is also highly intuitive to allow for easy setup and use.
- Energy Star certification from the EPA
- Five-year manufacturer’s warranty and low price
- High dehumidification 70-pint capacity
- Corrosion-resistant aluminum coils
- Compact and easy to install, access, and use
- Hose connection for continuous gravity drainage

4. AlorAir 1,300 Sq. Ft.
If you need a high-capacity dehumidifier that can fit into a restricted space, consider the Sentinel HD55 from AlorAir. This unit can remove up to 55 pints of water per day from a basement or crawl space with a floor area of up to 1,300 square feet.
For a unit with this high capacity, it is incredibly compact. This dehumidifier’s dimensions are 12.2 x 19.2 x 13.1 inches, so it doesn’t occupy valuable space, and it is easy to install.
The unit is easy to use, as well. You just select the moisture level setting you prefer and let it run on a continuous 24-hour cycle. There is no water tank, and you can let the water drain through the hose – no container emptying or water level checks needed.
There are several protective features to prolong the lifespan of this dehumidifier and ensure the best possible operation. The Sentinel HD55 is a compressor type and susceptible to frost build-up. To prevent ice from accumulating in the unit, it has a hot gas valve for defrosting that makes operation possible during the defrosting process.
This unit also comes with internal corrosion protection that prevents not only the formation of rust, but also freon leakage. The coil also has an epoxy coating for added protection and to maintain its heat, which increases the efficiency of the dehumidifier.
- Compact unit for easy installation in restricted areas

- Five-year product warranty
- HGV hot gas valve defrosting system for low temperatures
- G3 filter traps moisture as well as unpleasant odors
- Features a remote-control system that is easy to use

- INNOVATIVE FEATURES & WARRANTY - Features include auto restart function limiting disruption due to power outages, "Turbo" mode to increase the fan speed for maximum moisture removal, auto defrost...
The MAD20C1ZWS from MIDEA is a high-quality dehumidifier that can remove up to 30 pints of moisture per 1,500 sq. ft. for 24 hours. This capacity is ideal for average-sized areas with levels of moisture that range from 55 to 65 percent. If you have a smaller room, such as a crawl space or bathroom, the unit will be able to handle a higher moisture level.
The features of the MAD20C1ZWS are fairly standard— you will be able to find them on most other models as well. However, while this model may not have any stand-out functions, it has a low price tag and is a viable option for anyone who wants the best value for their money.
This unit includes a control panel with a humidity display. You can adjust the humidity level you prefer between 35 to 85 percent, and the dehumidifier will continuously monitor the level in the room and adjust its operation accordingly. This function includes and auto-comfort feature that you can activate by pressing the comfort button.
Because the MAD20C1ZWS is a compressor model, it features an auto-defrost function that turns the system off to melt the ice on the evaporator coils. You also get a turbo function with this model that you can activate for short periods to extract high levels of moisture in the air. This function is particularly handy after a flood or leak.
You have a choice of two drainage methods to get rid of the water that the unit traps. The first way is to collect the water in the 6.4-pint tank. If the dehumidifier runs at full capacity, you will have to empty the collection tank three to five times over 24 hours.
The second method is to connect a standard garden hose to the drainage connector and route the water to a nearby floor drain. This method relies on gravity, so the floor drain has to be nearby or below the container.
Other features you get with this model include a reminder when you have to clean the filter, continuous mode, and four wheels for better portability.
- Worldwide one-year parts and labor warranty
- Affordable price tag
- Wide moisture level setting range

However, the best thing about this unit is its installation flexibility with casters, a long 6-foot power cord, and an easily accessible display.
With the built-in RHT meter, you can view the current humidity level in your basement and select the ideal humidity level, preferably between 35 and 50 percent. The unit will then adjust its fan speed according to your needs and bring the humidity level down. If you are dealing with a moisture level higher than 65 percent, you can initiate turbo mode, which increases the fan speed to bring high moisture levels down quickly.
This unit comes with a 1.3-gallon water tank as one of its drainage features. Provided that the dehumidifier operates at full capacity, you will have to empty the tank three to five times per day. When the tank is full, it will trigger the auto shut-off.
If you don’t want to monitor water levels, you can connect a hose for continuous gravity draining and divert the water to a nearby drain. The floor drain has to be below the dehumidifier to ensure constant flow.
Other features this compressor unit has to offer include an auto-defrost function to protect its evaporator coils and a 24-hour timer. This model also has Energy Star certification, so you know that you are getting the best in terms of efficiency.

Because of this high moisture extraction capacity, this unit is suitable for industrial applications as well.
Despite this model’s high performance, it is incredibly compact and weighs only 45 pounds. You can also quickly and easily wheel the unit into the desired position on its smooth-rolling caster wheels. The power cord is six feet long, offering some flexibility in terms of the unit’s positioning in your basement.
With the Ivation 70-pint dehumidifier, you get two fan speeds—turbo and regular. The latter is suitable for routine moisture level maintenance in your basement. However, if you recently had a flood or burst water heater, and there is water all over your basement floor, the turbofan speed is your best option to get rid of excessive water vapor in the air.

Basement Dehumidifier Buyer’s Guide
To help you better understand why these models made our list, we’ve put together a handy buyer’s guide that we hope will answer any questions you have.
What is a Basement Dehumidifier?
A dehumidifier is an appliance that reduces and controls the humidity in the air. A basement dehumidifier has specific features for optimal performance below ground. However, some basement models also work well as regular dehumidifiers.
Do You Need a Basement Dehumidifier?
Caring for your basement is just as important as caring for your roof, flooring, and other structural components. A basement provides you with functional floor space, and it can significantly increase the thermal efficiency of your home.
However, a basement is susceptible to structural damage as the result of moisture build-up. Water can seep through the walls from the surrounding soil or accumulate when there is a pipe leak. Because many basements have no windows or ventilation, the humidity can rise and, over time, cause a wide range of issues that can be expensive to address.
A basement dehumidifier is an ideal solution to lower humidity levels in a room with no ventilation. While there may be others, the following symptoms are the most common signs you need a dehumidifier for your basement:
Condensation or Frost on Windows
When the humidity levels are too high, condensation on mirrors or windows is the first thing you will notice. During the winter months, the droplets may freeze, resulting in a layer of ice on these surfaces.
Marshy or Damp Smell
High moisture levels in the air create the ideal habitat for mold on wood, drywall, and the dirt on smooth surfaces. Mold and mildew are health hazards that can cause conditions such as allergies or fungal infections, among others. Fortunately, detecting the presence of mold is easy, as the fungus has a prominent damp smell that reminds one of wet socks, rotten wood, or mud.
The most effective way to get rid of mold and alleviate the health issues it causes is to keep your home dry. If your basement smells like mold and mildew, you need a dehumidifier.
When you are in an area with high humidity, you can detect the dampness on your skin and in your breath. If you enter your basement, and there is a notable moisture increase, that is an indication that you need a dehumidifier.
Humidity Levels Higher than 50%
If you are not sure if you need a dehumidifier for your basement, purchase a hygrometer and use it to measure the humidity in the air. If the hygrometer indicates a humidity level of higher than 50%, you need a dehumidifier to remove the moisture and prevent damage, mold and mildew growth, and rot. Ideal humidity levels are between 35 and 45 percent.
Humidity is the most significant factor in determining concentrations of dust mites, as they absorb moisture from the air instead of drinking it. As a result, if you have a dust mite infestation, it may be because of excessive moisture in the air.
Rot and Decay
Visible signs of rotting in areas of your basement is a tell-tale sign that humidity levels are too high. Wood that is turning white, grey, or black or wood surfaces that are soft or cracked are typically infected with rot. You may also notice that the paint on the walls is peeling, blistering, or cracking.
Optimizing Dehumidifier Efficiency
Installing a dehumidifier alone may not be sufficient to address the high levels of moisture in your basement. Before installation, you have to take specific steps to ensure that your dehumidifier performs at its best:
Close Windows and Doors
If outdoor air can enter your basement, your dehumidifier won’t be able to reduce the moisture levels effectively. Before switching on your dehumidifier, close all your basement’s windows and doors.
Address Sources of Humidity
A basement is inherently prone to high humidity levels, which is why you may need a dehumidifier. However, additional sources of moisture in the room can affect the performance of your dehumidifier.
Before installation, repair all leaks and remove standing water. You can also consider sealing the vents and floor with a 6-millimeter vapor barrier.
After determining that you need a dehumidifier, you have to select a one that meets your specific requirements. There are several buying considerations to take into account to make an informed buying decision.
Dehumidifier Types: Dessicant vs Compressor
You have a choice between two types of dehumidifiers, namely, desiccant and compressor. The best choice depends on the temperatures of the area, price, and energy efficiency—the right model for others may not work for you. You have to consider your needs and price tolerance carefully. Temperatures in the area where you want to place your dehumidifier are crucial, as units perform differently at varying temperatures.
Desiccant dehumidifiers use a descant wheel to absorb moisture from the air without the water vapor changing into a liquid state. Desiccant dehumidifiers are the best dehumidifiers in rooms with temperatures lower than 59°F (15°C).
The output air of this type of dehumidifier is also around 15 degrees warmer than the input air. If you want to warm the areas you are dehumidifying, desiccant dehumidifiers are the best alternative.
Compressors are widely regarded to be the best way to quickly lower the humidity level of a large indoor area. A compressor dehumidifier lowers humidity levels with a fan and cold condensation surface. When the warm air reaches the cooling surface, it results in condensation. Then, the liquidized water vapor is trapped inside the dehumidifier.
A compressor dehumidifier is ideal for areas with a room temperature above 59°F. Compressor models are cheaper to run than their desiccant equivalents but don’t help to heat the room either.
Capacity refers to the number of pints of water the unit removes from the air over a 24-hour period. Manufacturers often give their models a capacity rating of PPD (pints of moisture per day,) which is measured at temperatures of around 80°F and relative humidity of 60 percent.
Below is a general capacity recommendation that you can use:
- 30 – 45 PPD for small rooms with a humidity level between 45 and 55 percent
- 50 PPD for rooms with a humidity level between 55 and 65 percent
- 70 PPD for rooms with humidity levels of 65 percent or more and a moisture removal of 70 pints per day
Each dehumidifier has a unique capacity with the specified room size and humidity level. You can use the recommendation above as a general guideline, but the best dehumidifiers work at different levels of moisture.
You have the choice of three ways to drain water, namely gravity drainage, pump drainage, or manual drainage. With the gravity or pump drainage option, you don’t need to monitor the unit’s operation with an alarm or regular checks. With the manual drainage route, on the other hand, you have to empty the water collection tank regularly to prevent unnecessary downtime.
With the gravity drainage method, you have to connect a hose to let the water flow to a nearby location below the unit. If the unit has a pump, you can drain water to a location that is far away or above the dehumidifier.
Water Tank Size
Water tank size is only relevant if you have to drain the water manually, as it determines how many times you have to remove the water per day. For example, if the dehumidifier has a capacity of 50 PPD and a water tank capacity of 10 pints, you have to empty the water tank three to five times over a day, provided that the dehumidifier is running at full capacity.
Desiccant dehumidifiers work at low temperatures without any problems. With compressor models, however, this is not the case, especially in basements where temperatures tend to be relatively low. Frost build-up can lower a compressor dehumidifier’s efficiency and, ultimately, shorten the dehumidifier’s lifespan.
If you select a compressor model, make sure that it features a defrost mode. Models with this feature will monitor frost build-up and shut down the compressor when it detects frost. As the evaporator coils start to heat up, the ice will melt.
