While humidifiers are ideal for adding moisture to dry winter air, dehumidifiers are one of the easiest ways to get rid of excess moisture indoors. Too much moisture in your home can lead to some serious issues—mold, mildew, peeling paint, and more—but many full-size dehumidifiers are cumbersome to have in your home’s main living areas.

To combat moisture in smaller spaces like bathrooms, bedrooms, and even RVs, a small dehumidifier is likely a more suitable choice, allowing you to target specific rooms during showers, humid days, or heavy rainfall. (For bathrooms, an exhaust fan is another popular option.)

These appliances are much more compact than full-size models, yet most can still pull several ounces of water from the air each day. We’ve rounded up the best small dehumidifiers for every area of your home, which come in a range of sizes and prices.

Best Small Dehumidifiers

What to Consider

Extraction Rate

The dehumidifier’s extraction rate indicates how much moisture it can remove from the air per day.

For small dehumidifiers, the average is between 10 and 20 ounces. If you’re targeting the bathroom during and after showers, you can probably get away with a lower extraction rate. For all-day control in high-humidity rooms, aim for higher extraction rates.

Capacity

As dehumidifiers remove moisture from the air, they store the water in an on-board tank. Models with small tanks require more frequent emptying, but large tanks may be heavier and harder to carry. Most dehumidifiers automatically turn off when the tank is full so it doesn’t spill over.

Drainage

Another benefit of small dehumidifiers is that they’re often much easier to empty than larger models. With a full-size option, you typically need a drain hose (and somewhere to drain it to), but with compact models, you can simply remove the reservoir and dump it out in the sink, toilet, or outside. If you prefer to go the drain hose route, there are some small models that are compatible with hoses as well.

Noise

Dehumidifiers create a low humming noise when they’re running. Some find this comforting, like a white noise machine, but it can be annoying if it’s too loud.

For the quietest options, look for models that use methods other than compressors—such as the thermo-electric method used in our top pick from Pro Breeze. Manufacturers typically don’t list decibels for dehumidifiers of this size, so we’ve scoured reviews to determine the quietest small dehumidifiers.

How We Selected

To find the best small dehumidifiers, we researched a variety of expert sources, including Better Homes & Gardens, Bob Vila, and The Spruce, and combed through dozens of top-rated models, focusing on compact, portable models that are well-suited for small spaces. We narrowed down our selections based on factors such as ease of use, extraction rate, maximum capacity, and noise level, ultimately selecting a range of models customers love.

Electric Mini Dehumidifier

For rooms up to 250 square feet, this small dehumidifier is a top choice. It’s compact and easy to carry thanks to a built-in handle, yet it’s still powerful, extracting 18 ounces of water from the air each day.

Plus, it has a larger water tank than many other models we recommend, holding up to 52 ounces—that’s up to three days at maximum extraction. That means you won’t have to empty it nearly as frequently, but make sure to empty it regularly lest the water get mildewy.

This dehumidifier has an auto shut-off function when the water tank is full, and because it uses a thermo-electric cooling system to pull moisture from the air, it’s notably quieter than models that use a compressor.

Small Electric Dehumidifier for Home

The Pohl Schmitt electric dehumidifier is an inexpensive option for removing moisture in small rooms. It has a simple on/off toggle switch for operation, and it can remove up to 10 ounces of water from the air per day.

Its water tank holds up to 17 ounces total, which is one of the smallest tanks, but it isn’t surprising at this price. The unit will automatically shut off when it needs to be emptied.

This small dehumidifier is quiet during operation, so it won’t interrupt your daily activities, but users agree it’s most effective in small rooms despite the brand’s claims that it can support a space up to 225 square feet.

PureDry Mini Dehumidifier

This Pure Enrichment mini dehumidifier has a sleek, simple appearance, which makes it less of an eyesore than other models—ideal if you’re placing it in your living space. All you have to do is flip its power switch and it will get to work, removing 10 ounces of moisture from the air each day.

This dehumidifier is best suited for small spaces, such as a bathroom, and it will automatically shut off when its 27-ounce water tank needs to be emptied. Plus, it’s backed by a five-year warranty, which is longer than many other units.

Small Dehumidifier for Home

This Seavon dehumidifier is extremely quiet, with a noise level of just 30–35 decibels, so it won’t disturb you while you’re sleeping. It’s small and lightweight, fitting easily on a nightstand or dresser, and it can remove 12 ounces of moisture from the air per day.

The brand claims this dehumidifier can be used in spaces up to 215 square feet, but most reviewers agree that it works best in smaller rooms, especially if the humidity level is high. The tank is also big enough to hold a few days’ worth of water.

Small Air Dehumidifier With Air Purifying Function

The Tenergy Sorbi air dehumidifier does double duty in your home, serving as an air purifier as well as a dehumidifier. It has a replaceable HEPA filter that captures dust and allergens from the air, and it can also remove roughly 25 ounces of moisture from the air each day.

This unit is best suited for spaces around 200 square feet, and its one-liter water tank has a removable lid that makes it easier to clean. However, this dehumidifier has a minimum operation temperature of 50 degrees, which is higher than many other models.

E-333 Small Renewable Dehumidifier

The Eva-Dry Renewable Dehumidifier can be used in compact areas like closets, safes, and cars thanks to its cordless design. The small unit will work for 20 to 30 days, absorbing up to six ounces of moisture from the air.

Unlike many other dehumidifiers, this model uses silica beads to capture water, and they’ll turn green when you need to plug in the device to “renew” the beads. The dehumidifier can be reused again and again for years, and the brand offers a five-year warranty on it.

If you have a mildewy closet or garage space, this is an excellent no-frills solution that won’t require much upkeep.

Small Dehumidifier

If you’re looking for a dehumidifier that’s powerful but still lightweight enough to move around, this Frigidaire dehumidifier is one of your top options.

Made by a trusted brand, this unit is recommended for spaces up to 330 square feet, and it can remove up to 22.6 pints—or 2.8 gallons—of moisture from the air per day. It has three speeds, and you can even set your desired humidity level on the unit’s digital control panel.

This unit does have a 1.14-gallon water tank that you’ll need to empty, but the good news is that it has a continuous drain option, which will save you the hassle of manually emptying the container.

Just keep in mind that it’s louder than many other units, ranging between 43 and 49 decibels, depending on the setting.

Hanging Moisture Absorber Dehumidifier

Designed with closets and other storage areas in mind, DampRid Hanging Moisture Absorbers have a built-in hanger and convenient cordless operation. These dehumidifier bags come in a pack of three, and each pouch can capture up to 15.4 ounces of moisture.

There are several scents available if you want to make your space smell nice, but there’s also a fragrance-free option. Each of these moisture-absorbing bags will last around 60 days, but keep in mind that they’re one-time-use only—once the bag is full, you simply throw it away and put a new one up.

These are great for moisture-ridden attics or closets, but they also prove a worthy solution for making sure moisture doesn’t fester after a spill or pet accident in a small space.

Small Dehumidifier with Drain Hose

The Gocheer Dehumidifier is another mid-size option that comes with a drain hose for easier emptying. It can be used in rooms up to 800 square feet, and it can remove 1 liter (or around 34 ounces) of water from the air per day.

This dehumidifier is another good choice for your bedroom—it has a special “Sleep” mode that operates at just 15 decibels, as well as an optional color-changing nightlight.
