Best Dehumidifiers for Basements

Whether your basement is finished or unfinished (or even just a crawlspace), all below-ground spaces face the danger of experiencing too much moisture. That airborne moisture can eat away at your foundation, furniture, structure and decor. That’s why it’s important to find the best dehumidifier for your basement and save money on future repairs in the process.

Water Buckets, Pumps, Drainage & More

Keep Your Home Clean and Dry

Mildew and mold are prevalent in wetter, warmer climes but are definitely a problem everywhere that experiences seasonal fluctuations—like the Midwest. That mold, mildew and moisture can cause severe damage to how your home looks and its foundation down in the lowest levels. And you want to protect all of your downstairs belongings too, from sectionals and TVs to wet bars and ping pong tables. Investment in a moisture-remover now can help prevent damage in the long run.

How Do They Work?

These devices work by pulling air into the machine through refrigerated coils, stripping and condensing the water before exhaling out the new, dry air. If you’re looking to tell exactly how humid your home is with extreme accuracy, you’ll need to pick up a device known as a hygrometer. For many, that kind of accuracy just isn’t necessary.

What Size Dehumidifier Is Best For My Basement?

The answer depends upon a few factors, mainly the size of your space, your existing climate and the amount of moisture your home experiences. For example, a small room in a generally dry environment won’t need the hardest-working model. But the bottom floor of a large home that’s near a lake will probably need something much stronger that can run continuously. Below, we’ve pulled some of our recommendations for different room sizes. Keep in mind that each water pint capacity is measured in per-day operation, not how much a unit’s storage bucket can hold at once.

Frigidaire FFAD3533W1 Moderate Humidity 35 Pint White Dehumidifier

Designed to cover spaces as large as 500 square feet. Not all basements are massive, but they still need protection from moisture. Whether you live in a split level with a partial basement or have a crawlspace that’s dedicated to storage, you’re going to want to preserve its structural integrity. A 30 pint (a day) dehumidifier like this Frigidaire model is designed to tackle spaces of up to 500 square feet, making it perfect for moderately-sized downstairs areas and small spaces that tend to be damp. After the 16.9-pint water container is filled, users can either remove the splash-guard container or set it up for continuous drainage mode. With ENERGY STAR certification and the ability to work at temps as low as 41 degrees, it’s a good pick for low levels that don’t always get the most heat. This model is perfect for seasonal vacation homes as well.

Best Dehumidifier for Medium Basements or Continued Use

Friedrich D35B1A 35 Pint White Dehumidifier

Designed to cover spaces as large as 1,000 square feet. While it might have the same pints-per-day removal rate as the Frigidaire above, this Friedrich model is a true workhorse. With coverage capacities that can keep 1,000 square foot spaces dry, this model is optimized for mid-size basements: lower-level TV rooms, exercise spaces, offices and multipurpose areas. The built-in drain pump is the showstopper here, with the ability to push condensate as far as 15 feet (even vertically). If you plan to take advantage of pumping the water vertically into a sink or drain, make sure you purchase a hose that’s long enough to reach your drain. Other drainage options include the 16.2-pint bucket removal and standard drainage sans pump. This ENERGY STAR Freidrich model can be set to meet a preferred humidity level as well to keep your space from feeling too dry. Adjust between 30%-90%.

Best Dehumidifier for Large to Extra-Large Basements, Most User-Friendly

LG UD501KOG5 PuriCare 50 Pint Black Dehumidifier

Designed to cover spaces as large as 1,200 square feet. While the slightly smaller 13-pint condensate bucket might turn off some, this model has many features that make it incredibly user-friendly. The bright LED display and sleek black appearance make this device the opposite of an eyesore. Meanwhile, LG touts the ENERGY STAR model’s safety features, like their Safety Standby Mode. Every 23 hours, the machine goes into a one-hour rest period to avoid overheating. The materials are thermally resistant as well (glass, silicon, fiber and a steel body). That way, you’ll know it’s likely that you’re making an incredibly safe purchase for the valuables stored in your home. And if you set it up for continuous use, you won’t be removing that 13-pint bucket anyway.

Best Dehumidifier for Extra Large Basements and Wet Environments

Haier QPHR50LZ 50-Pint White Dehumidifier For Home Or Basement With Built-In Pump

Designed to cover wet spaces as large as 1,200 square feet. While the LG is optimized for user-friendliness and aesthetic beauty, this Haier model is made to work as hard as possible. A built-in hose and pump allow for continuous water removal pumped or drained, as well as classic removal via bucket. If the 15-pint bucket is removed or fills to the top, you’ll hear an alarm sound for ten seconds to alert nearby people that it’s time to empty. Meanwhile, the Smart Dry feature works to have the fan speed adjust to meet the set humidity level in the room. An automatic defrost control feature helps to ensure that the device never freezes over while you’re out of the room or out of the house, too. The compressor will simply turn off until any accrued frost melts away.

Still Not Sure Which Model Is Right For Your Home?

That’s okay, you’re in the right place. Extenuating circumstances might have you wondering if you should pick a higher-powered model to find the best dehumidifier for your basement— and in some instances that’s a good idea. If you live close to the water or in a humid climate, add 5-10 pints to the capacity level you’ll want. If many family members and friends hang out in the room, if there are many entryways, lots of windows, and if your laundry space and open bathrooms are nearby add a few pints as well. With these suggestions and this info, you’ll be ready to find the best dehumidifier for the basement.
