Keeping your home free of mold and mildew is crucial if you want to avoid the adverse health effects they can cause. In some situations, a large dehumidifier is your best defense against these moisture-loving intruders. But often, a personal dehumidifier is a better bet.
These pint-sized units work to control humidity in small spaces like your bedroom, bathroom, and closet. They are cheaper to run than large dehumidifiers, are much easier to store, and, often, are a better choice for precise humidity control.
We scoured the internet for the best small dehumidifiers for personal use. We rated each product we found based on performance, efficiency, ease of use, cost, and, of course, size to find the absolute best products out there, including one product so small, you might confuse it for your soap dispenser!

What We Look For in a Small Dehumidifiers
There are a lot of different factors that determine a dehumidifier's worth. When looking for the best small dehumidifiers, we paid special attention to each of the below categories.
Performance
The most essential factor in determining a good dehumidifier is how it performs.
The easiest way to determine if a dehumidifier will perform well enough is to look at the moisture-removal-per-day rating. It tells you how much moisture the product can pull from the air in 24 hours.
The coverage rating can also give you some insight into how well the unit performs. This number tells you what sized rooms the dehumidifier is rated for.
Although a dehumidifier with a larger coverage area is more powerful, it's not always best for small spaces.

Size
Personal dehumidifiers should be small enough to use in a cramped space. For a closet or bathroom, you'll want something compact enough to sit on the counter or fit on a shelf. For bedrooms, you'll need something slightly larger that still won't take up much space.
We only looked at humidifiers under 20" tall and gave extra points to impressively small ones while still powerful.
The dehumidifiers we've featured below are meant for small spaces like RVs and bedrooms.
For larger dehumidifier options, check out our article on the best dehumidifiers for basements.
Ease Of Use
Even small dehumidifiers can be a little complicated to use. There are often many removable parts and different settings that can cause issues with how the unit operates. We prioritized products that were simple yet effective and required no complex instructions to use.
If you are unfamiliar with how a dehumidifier works or what features may be included, you may want to read our helpful guide on how to use a dehumidifier.
Noise Level
There are many moving parts inside compact dehumidifiers, which means they will make some noise while in operation. For a personal dehumidifier, which is likely to be used in living spaces like bedrooms and bathrooms, how much noise the unit puts out can have a massive impact on how often you'll want to use it.
We only considered small dehumidifiers rated for having minimal noise output-around 40 decibels or less. Units that featured a super-quiet or whisper mode scored extra points.
Cost To Run
Small dehumidifiers are much more cost-effective to run than large units. But that doesn't mean they are all equal in the field of energy efficiency. We looked for units that were Energy Star certified and those with high-efficiency ratings and specialized low-energy settings.
Price and Warranty
Lastly, we paid particular attention to the price of each small dehumidifier we looked at. Only products with prices that reflected the build's quality and the unit's functionality were considered. In order to cover different budget requirements, we tried to pick at least one product from every price category.
Products that come with extended warranty periods scored higher than those with limited or no warranty.
Our Top Small Dehumidifier Reviews
Topping our list as the smallest dehumidifier is Homelabs Small Space Dehumidifier. This tiny unit is perfect for bathrooms and closets. It is small enough to sit on the counter behind the sink without taking up much space while still providing enough power to quickly rid the room of moisture after a long, hot shower.
Note: At only 8.5 inches tall and 6.5 inches wide, this undersized unit looks more like an automatic soap dispenser than a dehumidifier.
Unlike most super-tiny dehumidifiers, this one includes a water collection tank that is easy to access and empty. It holds an impressive 16 ounces of water and is powerful enough to collect up to 9 ounces of water per day.
With a coverage rating of 150 square feet, this little unit is perfect for bathrooms, closets, and small bedrooms.
In terms of features, this small dehumidifier is about as simplistic as it gets. It has an on/off switch and two indicator lights that tell you when the unit is running and full. The unit will turn off automatically once the reservoir reaches capacity.
The Homelabs Space Dehumidifier makes some noise while in use but is much quieter than your typical bathroom fan. Most users don't even notice the sound once it's been running for a while.
For those looking for a super-small dehumidifier for tight spaces that is uber portable, you won't find a better option than this one.
If you're in the market for a small dehumidifier that is still powerful enough to pull a fair amount of moisture from the air each day, look no further than the Vremi Compact Dehumidifier.
This sleek little unit is only 11 inches tall and 7 inches wide. The large 51-ounce reservoir means you can run this machine nonstop for days without having to empty it. And, because it can pull up to 17 ounces of moisture from the air each day, it is perfectly suited for humid bathrooms and bedrooms.
Note: Our favorite thing about the Vremi may be the ability to set your preferred humidity level. This feature allows you to leave the dehumidifier running without having to worry about overdrying out your space.
Once the pre-set humidity level is reached, the unit automatically shuts down. The Vremi will also automatically shut down once the reservoir is full.
This dehumidifier works best when used in rooms under 150 square feet that typically stay around 68 degrees. If the temperature in the room is much cooler or the space is larger, this little unit isn't going to be powerful enough to extract moisture from the air. But for your average bedroom that suffers from constant high humidity, this is a great buy.
If you're looking for a dehumidifier in your RV, this 3.2 Pint Dehumidifier from Magic Chef has you covered.
This unit is slightly smaller than the Vremi but has similar capacity ratings. But, unlike the Vremi, this one works more effectively at lower temperatures.
Note: The more compact build and ability to pull moisture from the air at temperatures down to 60 degrees make it ideal for the RV or cabin.
The Magic Chef can hold up to 51 ounces of water at a time. It doesn't have quite as high a moisture removal rating as the Vremi, but it will still get the job done in naturally humid environments.
Like the Homelabs mini dehumidifier, this one has a simple interface that features only an on/off button. The unit will shut down by itself when the reservoir is full, but there is no pre-set humidity level function.
We love the sleek design of this compact unit and how quiet and portable it is. It is ideal for the RV but works just as well in the bedroom and bathroom.
If you have a larger space to cover but are still in need of a compact unit that won't cost you a fortune, the Ivation Small-Area Dehumidifier is worth considering.
This is the largest dehumidifier to make our list. But, at 9.4 inches wide and 17 inches tall, it is still plenty compact enough to place on a dresser, shelf, or nightstand.
This dehumidifier's size is relatively small, but it has an impressively large capacity. It can hold up to 101 ounces of water at a time and can pull 68 ounces of moisture from the air each day.
Note: This product is guaranteed to offer relief for basement living areas, basement bedrooms, or living spaces plagued by high humidity.
This dehumidifier has more features than your typical personal use unit. You can choose between two fan speeds and dial up the humidistat to your preferred humidity level. Once the room reaches your set humidity or the reservoir fills up, the machine will automatically power off.
On the lowest fan setting, this unit puts out considerably less noise than your typical dehumidifier.
For really humid areas that need constant attention, this unit comes with the option to hook up a drainage hose for continuous use.
The Ivation is a little larger than others featured here but well worth the slightly higher space investment for an energy-efficient, multi-feature dehumidifier that gets the job done in spaces up to 300 square feet.
In need of a mini dehumidifier but on a limited budget? The Pro Breeze Mini is comparable to the Vremi and Homelabs dehumidifiers but comes at a more affordable price.
This little unit is about the same size as the Vremi at 7 inches wide and 11 inches tall. However, it has a much smaller water tank and can only hold 16 ounces of water at a time.
Its moisture removal capability-9 ounces per day-is more closely aligned with the ultra-small Homelabs unit.
Despite its small capacity, this unit is rated for rooms up to 215 square feet. It is also incredibly energy efficient and is ideal for those in need of a unit they can run continuously.
The low wattage rating also makes this little unit a good choice for RVs. And it works relatively well at temperatures as low as 60 degrees, another useful feature for a camper dehumidifier.
Note: For that low price tag, you do have to trade some functionality. Like many other simple-use mini dehumidifiers, this one only features an on/off switch.
It does automatically turn off when the reservoir fills up but has no internal humidistat.
Another well-priced portable mini dehumidifier, especially for larger spaces, is the Seavon Portable Dehumidifier.
This cylindrical unit is impressively compact, with a diameter of 6.3 inches and a height of 10 inches. Despite its small size, it is rated for rooms up to 285 square feet.
It has a reasonably decent water reservoir capacity of 35 ounces and can remove up to 16 ounces of moisture from the air each day.
Note: Considering the size and coverage of this dehumidifier, you can use it for just about any room in the house.
If you like a little ambiance while you sleep or shower, you may consider putting this unit in your bedroom or bathroom. The smartly designed water tank doubles as a light feature with seven different LED color options. You can set the light to static or off, depending on your preferences.
Aside from the light feature, this unit is fairly simplistic. It can be turned on high or low using the single power button, but it does not have a humidistat or timer.
The unit will turn off automatically if the water reservoir fills up.
Some users report that the unit gets hotter than others and puts out warmer air. But overall, we love the price of this fun dehumidifier as well as the included 2-year warranty.
