4 Best Dehumidifiers for Basement - Reviewed and Rated 2021

Basements are probably one of the most challenging places to regulate the humidity in the house.

It’s a potent combination of damp, cold, and mildew or mold. You need an equally potent dehumidifier to tackle the challenge.

Coverage and capacity are the factors we looked into the most ardently. After much investigation, the EcoSeb stood out among its competitors.

The most significant advantage is the wide temperature range, giving it the flexibility to be used in almost any climate. It also gives moisture absorption power that’s consistent under temperature swings.

4 Best Basement Dehumidifiers - Reviews

When you’ve thought through the various factors above, the next step is to choose the perfect dehumidifier for your basement. Here are our TOP FOUR picks:

1. EcoSeb DD122EA Dehumidifier – Best Pick For Cold Areas


The unit is compact and has a foldable carry handle so that you can move it around quickly. It’s also lightweight at 13.2 pounds.

Operating Temperatures

The EcoSeb DD122EA is our dehumidifier of choice for basements that get extremely cold. The unit can be used in temperatures as low as 34 Fahrenheit, or near freezing! On the upper range, it can operate as high as 104 Fahrenheit.

Water Tank Capacity

The DD122EA is capable of absorbing up to 15 pints of moisture in 24 hours, regardless of the temperature. The water tank itself is small (maximum capacity of 4.2 pints).

It has a drainage outlet at the back so that you can connect to a hose and drain it via gravity.


Safety features are also built into the DD122EA, and you can place it safely on a higher elevation thanks to its Anti-Tilt feature. It shuts off automatically if it tilts past a certain angle.

The Auto Restart function turns it on automatically right after a power failure.

Other Features

The sensitivity to temperatures is possible because the DD122EA doesn’t use a compressor. Instead, it uses a desiccant to absorb moisture from the air.

Desiccant dehumidifiers are not only efficient but also safer. It doesn’t use dangerous gases, which also means it doesn’t need defrosting.

The feature makes it quiet, too, operating at only 34 dB.

The DD122EA also has extra modes you can use—it functions as an effective laundry dryer, for example. The Laundry Mode button enables you to dry your clothes indoors for around two to four hours—perfect for drying laundry on rainy days or during the winter.


The EcoSeb DD122EA is a flexible dehumidifier for your basement, thanks to the wide temperature range. Safety features coupled with efficient moisture absorption is a winning combination.

If you live in an area that doesn’t get too chilly, then the hOmelabs 70-Pint Dehumidifier is a solid deal. The unit can cover up to 4,500 square feet, making it perfect for even the dampest of basements.


It is far larger than typical dehumidifiers you’ll see on the market, given its power and capacity. The wheel casters at its base do a fantastic job of still making it portable, though. You can easily roll it around the house and position it where you need it the most.

Humidity Control

The model is the most powerful within the hOmelabs line of dehumidifiers, capable of removing up to 70 pints of moisture in the air in 24 hours. It has ample capacity to handle moist areas with ease, like basements and cellars.

Water Tank Capacity

One of the highlights of the hOmelabs Dehumidifier is its slick, minimalist design, which extends towards its usability. Operating this unit is easy– select your target humidity and turn it on.

It has a water tank that can fit 1.8 gallons of water, which necessitates frequent emptying in a day of use. It does have an auto-shutoff, though, so it turns off automatically when the water tank is full.

Drainage Capabilities

For complete autonomy, we recommend using the gravity drainage feature, though. Hook it up to a standard garden hose and run it from the outlet at the rear to drain the water.

Now that’s truly “set it and forget it.”

Other Features

Other notable features include a 24-hour timer and a Continuous Mode.

It also has adjustable speeds, for when you want to dehumidify an excessively damp basement quickly.


We find that the hOmelabs 70-Pint Dehumidifier is one of the best and most potent models we’ve found.

The broad coverage and capacity can positively regulate excessive moisture in your basement or large room.

A simple hookup to a hose means you can use it autonomously and leave it in your basement to do its magic, with minimal supervision.

3. Colzer 70 Pints Portable Dehumidifier – Best Pick for Compact Power

Despite its small size, the Colzer 70-Pint Dehumidifier is surprisingly potent. It’s capable of covering a room up to 4,000 square feet in size.


Thanks to its portability, you’ll find that you’ll move it around the house as often as you need it. We’re especially fond of using this dehumidifier in the garage and the bathroom, to the point where we have had to buy a second unit!

The small form factor also makes this dehumidifier blend in a room, working quietly in the background.

It won’t call attention to itself, and you can flexibly place it anywhere. The hidden casters and side handles make it especially easy to transport.

Humidity Control

The Colzer dehumidifier has an intelligent humidity control feature. When set between 30 and 80 percent, it can accurately detect the moisture level in the air. Then, it will turn itself on or off automatically to maintain the set humidity level.

Its moisture removal rate is an impressive 70 pints per day. For an average basement, this is more than enough.

Water Tank Capacity

The dehumidifier has a water tank that can accommodate up to 9.5 pints of water, which is a reasonable capacity given its size.

Drainage Capabilities

For a more autonomous operation, you can affix its gravity drainage port. A 6.6 ft. hose is included with the unit, so just hook it up and let it get to work.

Other Features

The control panel is easy to use and gives you access to quite a few functions—chiefly, the Laundry Dry Mode. The handy feature provides you with the option of drying your clothes indoors, without the use of an invasive dryer.

The unit also has adjustable fan speed, a 24-hour timer, and a humidity indicator.


Do we love the Colzer 70-Pint Dehumidifier? Yes, we do!

It’s incredible how a lightweight and compact unit has the power to regulate the moisture of an entire basement. Throw in humidity sensors, drainage features, and the dry laundry mode, and you have yourself a winner.

Our final review is for the Aprilaire 1830, which was designed to be the ultimate dehumidifier for your basement.


The model is a departure from the wheel casters and handles of other models that are meant to be portable. The 1830 is specifically customized for basement use, so it needs to be set down on a much more permanent basis.

The layout also makes it ideal for hooking up to a sealed crawl space.

Drainage Capabilities

Despite the complicated exterior, the 1830 is easy to use. It features a no-water tray (yet another unique selling point that sets it apart from its competitors). Instead, it drains directly via gravity to a hose or drainage pipe.

It is a dehumidifier that wants minimal supervision.

Humidity Control

The power of the 1830 means it can absorb up to 70 pints of water per day, with a coverage of 3,800 square feet. Once the target humidity is set, the unit will run automatically to maintain the desired level.


If you want a permanent solution to dehumidifying your basement, the Aprilaire 1830 Pro is your best bet. It looks complicated, but it’s effortless to use.

Final Verdict

dehumidifier at the basement

We’ve explored the best dehumidifier for your basement in more detail and advised you on how to find the most powerful unit out there.

It was difficult, considering the myriad of factors that come into play, like the temperature of your basement throughout the year.

For the ultimate in flexibility, however, we recommend the EcoSeb DD122EA Dehumidifier.

The operating temperatures are as low as 34F, so you can use it anywhere and at any time of the year. Its desiccant technology regulates humidity safely and quietly, regardless of how hot or cold it gets outside.

For a damp basement, it’s the kind of dehumidifier you won’t regret adding to your collection.

How to Pick the Best Dehumidifier for Basement

Basements are known as one of the damper areas in your home, which is why it is so prone to molds. It is exacerbated by the fact that it is also the least maintained or cleaned area of the home.

A dehumidifier is crucial for the prevention of mold and bacterial growth in your basement. Combined with proper mold prevention techniques, you can avoid this silent but deadly nuisance in your home.

Here are some factors you need to consider when you’re buying a dehumidifier:

Humidity Control

The basement usually has one of the highest humidity levels in the home, so you need a powerful dehumidifier to regulate it. Humidity levels of around 50 to 55 percent are ideal in your basement.

Your dehumidifier will need to extract a certain amount of moisture from the air efficiently. Based on an average-sized basement, the lowest you can afford to go on humidity control is about 30 pints in 24 hours.

Account for more if your basement is large or particularly damp.

Water Tank Capacity

The dehumidifier works by collecting moisture from the air and dumping it into the water tank. When it fills up, the dehumidifier stops working until you empty it (a feature that avoids spillage).

The capacity is vital if your dehumidifier doesn’t have an automatic pump or drainage feature.

If your capacity is too small, then you’ll need to manually empty the tank, which is quite inconvenient.

For water capacity, we recommend a minimum of around 1 liter, with an ideal tank of 2 liters.

Defrosting Feature

Aside from being the dampest area, basements also tend to be the coldest part of the house, especially during winter.

It can quickly lead to frost accumulation in the mechanism, which can damage or lower the efficiency of your dehumidifier. If this is an issue in your location, then you need to invest in a dehumidifier with a defrost feature. It enables the unit to monitor its coils and compressor for any frost and shut itself on or off as needed.

The frost issue ties into our next factor, too.

Operating Temperature

Basements usually suffer from extreme temperatures. It’s the coldest place in the house in winter, and it tends to be muggy and hot in the summer.

You need to check out the temperatures at which your dehumidifier can run safely to avoid malfunction during these extreme seasonal fluctuations.

For basement dehumidifiers, a wide temperature range is essential.

It depends greatly on the climate in your location and the seasonal extremes where you live. Check the temperature throughout the year and select a powerful dehumidifier that fits into the range.

Drainage Capabilities

Basements are usually the least-visited location in the house. A dehumidifier left there should ideally be able to run itself continuously for a long time, without any need for maintenance or manual tank emptying.

We recommend investing in a dehumidifier with drainage capabilities. It makes the unit a “set it and forget it” kind of operation—far more convenient for out-of-sight corners of the home.

When it comes to drainage, you have two options—gravity or a drainage system.

Using gravity can be useful in the right setting, and most dehumidifiers would have a drain outlet. You would need to connect a hose and have it feed into your basement’s existing drainage system.

Note: You’re relying on gravity, so you need to place the dehumidifier higher than you might have planned.

If this is not possible, or if your basement doesn’t have a drainage system, consider pump drainage on your dehumidifier. It allows you to pump the water to a location much further away, like to your garden or bathroom.

Not all dehumidifiers have this feature, however, and it tends to be more expensive.
