9 Best Dehumidifiers for Basements: Reviewed, Rated & Compared

1 - HOmeLabs

The dehumidifier from hOmeLabs is one of the highest capacity portable units currently on the market. It is also affordable for almost every budget and has a host of features, easily making it our top pick for basements.

The portable dehumidifier actually comes in three different sizes so that you can pick the one best suited for your space. The largest model can comfortably remove moisture in areas up to 4500 square feet. This is the best dehumidifier for large basements. If your basement is smaller, you may be able to save a bit of money by going with a smaller model.

Either way you go, you can expect up to 50 pints of moisture removed, per day, helping you keep your basement between 30 and 50% humidity. The hOmeLabs models are also sleek and stylish, so you don’t have to worry about bulky eyesores in your room.

The best feature here is the ability to choose how the unit drains. By default, the machine collects the condensation in a collection tray and will shut off when the tray is full. After you empty the tray and put it back in service, the machine will come on and start working again.

If this is a hassle (or if you don’t visit your basement often), you can connect a garden hose (5/8^th inch inner diameter), and the unit will drain continuously without any extra work on your part. For the price, the hOmeLabs dehumidifier is arguably the best value dehumidifier for basements. Durable, rugged and long-lasting, you will enjoy having this unit in your home.

Our Top Pick For Basements

2 - AIRPLUS

If you have a smaller basement, then you may not need a large capacity dehumidifier. In this case, the best rated unit for small basements is the Airplus system.

This humidifier is ideal for small spaces and will work wonders in your basement. It offers you the choice of drainage options that best suit your needs. The tank will hold 1.5 liters of water (about half a gallon) and will need to be emptied about every 2 or 3 days.

If you prefer, there is a hose attachment (hose included) that allows for continuous draining as long as you have a sink or drain nearby. This unit will remove up to 30 pints per day, depending on the relative humidity and temperate (as well as your settings).

The touch control display features 4 operational modes and 2 timers. You can set it to come on during a 24 hour period or off during the same period. You also get to choose between fan speed modes for drying, sleeping (noise reduction), and standard operations.

Once set up in your basement and your selections are made, you can leave the dehumidifier to do its job. However, because it is a portable unit, it will need to be checked on from time to time to ensure it is still running as expected and the draining hose has not come dislodged.

With a 2-year warranty and money-back guarantee, you have nothing to lose with this model, except, of course, excess moisture in your basement.

Best Rated Dehumidifier For Small Basement

3 - AlorAir

If you are looking for the top of the range and only want the best, then this might just be your next dehumidifier. The AlorAir dehumidifier is a continuous run refrigerant model that offers superior moisture removal for wet basements.

Not only does this model run constantly, but it is also engineered to use less energy than most other models, keeping your monthly energy bill low. It also uses a gravity drain system, so you don’t have to worry about water tanks or pump malfunctions.

Capable of removing up to 120 pints of moisture per day, this unit will efficiently work in basements up to 1300 square feet. It also allows you to run year-round with a special hot gas valve (HGV) defrosting method.

Utilizing the HGV, the machine doesn’t need to shut off to defrost. Instead, it will work continuously, even through frost at temperatures as low as 36 degrees Fahrenheit. For the basement that stays wet, this is the cure.

Not only does the machine work year-round and move a lot of moisture from your basement, but it is also backed by a 5-year warranty and plenty of after-sales customer support. If you ever have questions or concerns, the techs spread nationwide will happily help you out.

Top Of The Range

4 - Vremi

We’ve covered the large basements, the small basements, and the wet basements. What if you are somewhere in between? The Vremi dehumidifier is the best model for mid-sized basements and should suit your needs just fine.

Once again, you have three sizes to choose from, with ranges between 1500 and 3000 square feet, you are sure to find the model that fits your basement size with ease. Just don’t forget to add a little extra space, so your unit doesn’t have to work overtime.

With the Vremi model, you have two drain options. The large collection tank will hold about 1.6 gallons of condensation before the machine shuts off. If you prefer less work, you can connect a garden hose to the machine for a continuous drain. Make sure the hose is always going downhill to prevent a clog.

This model also has many features that help you out, such as the filter indicator letting you know when it is time to replace it (usually about every 90 days, depending on location and use). You also get a timer and turbo settings so you can let it run as needed or speed things up for a faster moisture removal period.

The 1-year warranty is a little slim for this industry and is about the only negative thing to offer here. However, during the warranty period, customer service is easy to get a hold of and happy to help. In some cases (depending on where you buy), they offer help to ensure you remain happy even after the warranty period.

Best Dehumidifier For Mid-Size Basement

5 - Aprilaire 1870 XL Pro Dehumidifier

If you have a wet basement, are rebuilding or modifying, or already have mold growth, you need the Aprilaire XL Pro. This is the most powerful dehumidifier for basement mold and will get your space back to homeostasis quickly.

This machine can move air and is designed specifically for basements, crawl spaces, and installation as a whole-home unit. With 130 pints per day moisture removal, you can reduce your basement to less than 50% humidity in no time.

With continuous draining, you don’t have to worry about emptying water trays or fiddling with pumps. In fact, this unit is relatively maintenance-free. The only exception is during the initial set up if you need to make changes or the once-yearly filter cleaning.

This unit does get loud, reaching upwards of 55 to 60dB. While this isn’t ear-shattering, in a basement it can echo and cause some disturbances upstairs. Insulation and padding will help reduce the noise levels and echoes, though.

The XL Pro comes in many sizes and capacities ranging from 2800 feet and 70 pints per day to the large capacity 7200 feet, 130 PPD model reviewed here. With a 5-year warranty, you can rest assured that this unit will perform as expected and offer you years of comfort and mold reduction.

Most Powerful Dehumidifier For Basement Mold

6 - Frigidaire

With a brand like Frigidaire, you would think they know something about moisture, condensation, and humidity. That is why their dehumidifier is easily the best portable model for basement use.

With a powerful fan system, this model moves up to 152 CFM of air and can remove up to 50 pints of moisture in 24 hours. The best thing, though, is that this unit is highly portable and efficiently runs wherever you put it.

The controls on this unit are very user-friendly and offer you the ability to set timers, control humidity levels, and select fan speeds. It also features an auto shut off function based on time or water level in the collection tank.

The tank itself holds an incredible 2 gallons of water and has a simple front load system to make it easy to get to. Not only that, but Frigidaire thought of everything. The tank has a center-mounted handle and anti-slosh sides, so emptying it doesn’t make a mess.

If you’d rather not deal with emptying the tank, you can connect a garden hose and select pump operation. This will give continuous draining through the hose, so your maintenance routine becomes near zero.

The filter is also front-mounted for easy access and cleaning. The only downside here is that this unit can get a bit noisy, and the replacement filters aren’t easy to find. If you do find them in stock, it is recommended that you purchase a couple so you always have one when needed.

The warranty is a two-part warranty and covers the parts and labor of the unit for 1 year. The sealed system (fan, refrigeration, and pump) are covered for 5 -years.

Best Portable Dehumidifier For Basement

7 - Midea MAD20C1ZWS

If you are looking for an affordable and functional dehumidifier, Midea has the answer. Their lineup includes some of the most reliable and best cheap dehumidifiers for basement, bathroom, or bedrooms around. They also produce quality air conditioners which you can check out here.

There are three models to choose from, including the highly budget-friendly 20 PPD model. You can also upgrade to larger models, up to the 4500 square foot, 50 PPD model. However, for the best experience, we found the 20 PPD is adequate for almost all basements.

With up to 1500 square feet of airflow space, the Midea dehumidifier can move a lot of air. About 128 CFM results in maximum moisture removal. Of course, as with most portable units, you have drainage options. The water tank itself is relatively small, only holding about 0.8 gallons. In a basement setting, this can mean having to empty it every day.

However, there is a continuous drain option that only requires a hose and a place to empty it. Once set up with drainage, you can use the touch-sensitive controls to set the unit exactly how you need it.

This model also features indicators for the fan speed, humidity levels, filter replacement, and tank full indicator. You won’t ever have to guess what the machine is doing or when things need to be maintained.

It does come with a 1-year warranty, and customer service is great when they are needed. However, it seems that any problems you may have (which is rare) happen well after the warranty period.
