A damp basement is more than just an unpleasant smell; it’s a breeding ground for mold, mildew, and dust mites that can damage your home’s structure and affect your family’s health. If you notice a musty odor, condensation on windows, or that sticky feeling in the air, it’s a clear sign that humidity levels are too high. Investing in one of the best home dehumidifiers for basements is the most effective way to take control of your indoor air quality. These appliances work by pulling excess moisture from the air, creating a drier, healthier, and more comfortable environment.
When choosing a basement dehumidifier, you need to consider the size of your space, the capacity of the unit, and features like a built-in pump or continuous drainage options.

hOmeLabs 70 Pint Energy Star Dehumidifier
I consider the hOmeLabs 70 Pint model a workhorse for medium to large basements. It’s incredibly effective at its main job: pulling a significant amount of water from the air.

Frigidaire High Efficiency 50 Pint Dehumidifier
Frigidaire is a trusted name in appliances, and their 50-pint dehumidifier lives up to the reputation. I found it to be a solid, reliable choice for a standard-sized basement. It’s not as flashy as some other models, but it gets the job done consistently. The build quality feels robust, and it’s designed to be user-friendly. The front-loading bucket is easy to remove and empty, and there’s a clear indicator light that lets you know when it’s full. It also has a built-in humidistat, so you can set it and forget it, allowing the unit to maintain your preferred humidity level automatically.
This model is particularly good in cooler basement temperatures, as it includes an auto-defrost function. This prevents the coils from freezing up, which means it can continue to remove moisture even when the temperature drops. This is a critical feature for basements that can get chilly. While it does have a port for a hose for continuous drainage, you may need to purchase an adapter separately. The wheels make it relatively easy to move around, which is helpful if you need to position it in a specific spot. It’s a no-nonsense, effective dehumidifier from a brand you can count on.
Pros
- Trusted brand known for reliability
- Effective auto-defrost for cooler environments
- Easy-to-clean bucket and clear full-bucket alert
Cons
- Continuous drainage may require an extra adapter

Waykar 80 Pint Dehumidifier with Pump
If you have a very large or exceptionally damp basement, the Waykar 80-pint dehumidifier is a powerhouse worth considering. The most significant advantage of this unit is the built-in condensate pump. This feature is a game-changer because it allows you to pump the collected water upward and out, for example, into a sink or a window well. This means you have much more flexibility in where you place the dehumidifier; it doesn’t have to be sitting right next to a floor drain. I found the pump to be quiet and effective, making continuous drainage truly hassle-free.
Despite its high capacity, the unit is surprisingly compact and comes with sturdy wheels, so moving it around your basement is simple. The digital control panel is intuitive, and you can program a 24-hour timer or set a specific humidity level. It also has an auto-restart function, which is convenient if your power flickers. One thing to note is that with this much power, it does generate more noise than a smaller unit, but that’s the trade-off for such strong performance. For serious moisture problems, the Waykar is an excellent solution.
Pros
- Built-in pump offers superior drainage flexibility
- Very high moisture removal capacity
- Compact design with wheels for easy mobility
Cons
- Louder operation due to high power

For those who love smart home technology, the GE 50 Pint Dehumidifier with WiFi is a fantastic option. I really appreciated the ability to control and monitor the unit from my phone using the GE Appliances app. You can turn it on or off, adjust the humidity setting, set schedules, and receive alerts—all from another room or even when you’re not at home. This is incredibly convenient for managing your basement’s environment without having to go downstairs. The unit itself is sleek and performs reliably, effectively keeping humidity in check.
Beyond the smart features, it has all the practical functions you’d want. It offers both bucket and continuous drainage options, and the bucket is easy to handle. The display panel on the unit is clear and easy to read. Like other quality models, it has an auto-defrost feature to handle cooler basement temperatures. The WiFi setup was straightforward, but as with any smart device, it requires a stable home network. If you’re looking to integrate your basement’s climate control into your smart home system, this GE model is a top-tier choice.

This pump allows for vertical drainage, giving you more placement options in your basement without relying on gravity alone. I found the unit to be quiet for its size, which is a big plus if your basement is a living space or workshop where noise matters. It’s also Energy Star certified, so it’s cost-effective to run over long periods.
The controls are simple, with a clear LED display and buttons for setting the timer and desired humidity. The water tank is transparent, so you can easily see how full it is, and the continuous drainage option is there if you prefer to use a hose. The build quality feels solid, and it rolls smoothly on its four caster wheels.

Pros
- Excellent value with a built-in pump
- Quiet operation compared to similar models
- Energy Star certified for lower operating costs

It’s designed to work efficiently in low temperatures, making it ideal for unfinished or crawlspace basements that can get quite cold. The industrial-grade construction gives you confidence that it’s built to last. The most notable feature is the powerful condensate pump, which can lift water up to 15 feet high.

This unit is all about performance and durability over aesthetics. It’s functional and effective. It has a simple control panel with a digital readout, and it includes a washable air filter to help keep the air cleaner. While it is louder than a typical residential model, that’s because it’s built with a more powerful compressor designed for extreme conditions.

Pros
- Excellent performance in low-temperature environments
- High-lift pump for difficult drainage situations

SEAVON Electric Dehumidifier for Small Spaces
Not every basement is a sprawling area; some are small storage rooms or cozy dens. For these spaces, a large, powerful dehumidifier is overkill. The SEAVON Electric Dehumidifier is a perfect compact solution. It’s small, lightweight, and incredibly quiet, so you can place it on a shelf or in a corner without it being an eyesore or a disturbance. I was surprised by how much moisture it can pull from the air in a small, enclosed area. It’s also very energy-efficient.

Buying Guide for the 10 Best Home Dehumidifiers for Basements | 2025
If you have a basement, you probably know the struggle with damp air. That musty smell, the feeling of cool moisture on the walls—it’s not just unpleasant, it can be bad for your home and your health. I’ve spent a lot of time figuring out what makes a good basement dehumidifier, and it really comes down to a few key things you should look for.
First, think about capacity. This is measured in pints of moisture removed per day. For a basement, you generally need a machine with some muscle. I usually recommend looking at models rated for 50 pints or more. But here’s the catch: there are two capacity ratings. The AHAM-rated capacity is the one to pay attention to; it’s measured at a standard 65% relative humidity and 80°F, which is a more realistic baseline for a basement. The other rating is often measured under much more humid conditions, making it look more powerful than it actually is for everyday use.
Next, consider the water removal system. Basement dehumidifiers typically have a built-in pump or just a bucket. A bucket is fine if you’re around to empty it every day, but a built-in condensate pump is a game-changer. It lets the unit pump water upward and directly into a floor-level drain or even out a window, which is perfect for finished basements where the drain might be across the room. This is a feature I always suggest for basement setups.
You’ll also want to look at features that make life easier. An auto-restart function is crucial if your area has power outages; the unit will turn back on with your previous settings once the electricity returns. A continuous drainage option (even without a pump, using gravity) is another great convenience. And don’t forget about the noise level—if your basement is a living space, you’ll want a model that operates quietly.
Finally, energy efficiency matters, especially since this appliance might be running quite a bit. Look for an Energy Star certification to help keep your electricity bills in check. By focusing on these factors—capacity, pump, convenience, and efficiency—you can find a unit that will effectively tackle your basement’s humidity problems for years to come.
FAQ
What size dehumidifier do I need for my basement?
This is the most common question I get. The size you need depends on the square footage of your space and how damp it is. As a general rule, a moderately damp basement (around 1,000-1,500 square feet) will do well with a 50-pint model. If your basement is consistently very wet, has a musty smell, or is larger, you should step up to a 70-pint unit. It’s usually better to have a slightly oversized dehumidifier than one that has to work constantly at its maximum capacity.
Is it better to have a dehumidifier with a pump?
For a basement, I almost always say yes. A built-in condensate pump gives you so much more flexibility for placement. You aren’t limited to putting the unit right next to a floor drain. The pump can send water up and out through a window well or into a utility sink. If your basement is unfinished and you can place the dehumidifier right next to a drain, a gravity-fed hose might be sufficient. But for finished basements, a pump is a huge advantage.
Where is the best place to put a dehumidifier in a basement?
You want to place it in a central location with good air circulation. Keep it at least a foot away from walls and furniture to allow air to flow freely into the intake grilles. Avoid corners where air is stagnant. If you’re using the unit’s pump, you can place it anywhere you have an electrical outlet. If you’re relying on gravity drainage, its location will be determined by your floor drain.
Should I run my basement dehumidifier in the winter?
It depends on your climate and your basement. In colder months, the air is naturally drier, so you probably won’t need to run it. In fact, running a standard dehumidifier in very cold temperatures (below 65°F) can be inefficient and may cause the coils to freeze. However, if your basement is heated or you live in a milder, damp climate, you might still need it. Many modern units have an auto-defrost feature that allows them to operate in cooler temperatures. Just keep an eye on your humidity levels.
How do I know if my basement humidity is too high?
The ideal relative humidity for a basement is between 30% and 50%. You can buy an inexpensive hygrometer to measure it. Without one, clear signs include a persistent musty odor, condensation on windows or pipes, damp feeling on walls and floors, and the appearance of mold or mildew. If you notice any of these, it’s time to start looking at the 10 Best Home Dehumidifiers for Basements | 2025 for a solution.
Are dehumidifiers expensive to run?
It varies, but an Energy Star certified model is designed to be more efficient. The cost depends on your local electricity rates and how often the unit runs. On average, a good dehumidifier might add $10 to $30 to your monthly bill during the humid season. Using features like a built-in humidistat to set a specific target (like 45% RH) instead of letting it run continuously can help manage the operating cost.
