9 Best Small Dehumidifiers - Reviewed and Rated 2021
There are few things less pleasant than damp rooms, filled as they are with muggy scents, stickiness, and at certain thresholds, dust mites, mildew, and mold.
Regardless of whether you need to treat your allergies or just don’t want to deal with overly moist air, a humidifier can help.
These devices range from small to large and typically work by using a fan to move air over refrigerated coils to remove moisture from the air and collect it in a tank.
We ran through a series of different models to bring you the best small dehumidifier easily accessible to anyone.
In a Rush? Here’s our winner..
Editor’s Choice: Pro Breeze Mini
Of all the dehumidifiers you can pick, the Pro Breeze Mini is easily the best. It boasts an effective radius of 1,200 ft3, clearing out moisture at a rate of 9 oz. of water per day. This works great with its 18 oz. tank, meaning you can run it for 48 hours before you need to change it.
It’s obvious when you need to empty the tank. The dehumidifier automatically shuts off and flips on an LED light, so you know the instant it’s full. This is all tied together by a startlingly low energy usage of 23W per hour. Get the Pro Breeze Mini now.

- Auto shut-off functionality
If you’re seeking an excellent small dehumidifier, you need look no further. The Pro Breeze Mini is a perfect choice that can dehumidify whatever room you put it in.
Featuring a total area covered of 150 ft2 it’s capable of pulling out 9 oz. of water per day, which, combined with its 18 oz. tank means 2 solid days of operation.
Once it’s full, the unit will let you know. From there, emptying the tank is as easy as pulling out the plug and allowing the water to drain. Shut it and reconnect it so it can continue keeping your room dry.
The unit also comes with a thermo-electric cooling system that means it can run at a relatively quiet volume. It’s not quite a whisper, but it’s not disruptive.
The amount of energy this unit uses is startlingly low, with just 0.55 kW used in 24 hours. You won’t have to worry about complicated operation instructions or steep electric bills. It just works.
- Very low energy usage, meaning low electric bills
- Easy to maintain and operate

- Uninspired, simplistic design
Who Should Get This?
If you need a small dehumidifier that’ll do the job in any room you put it in, this model is an excellent choice for your home or office.
- Uses silica beads
- 333 ft3 covered
- Dimensions: 9” x 8.25” x 2.88”
- Continuous pump type
- Non-toxic, child- and pet-safe
The lightweight and versatile Eva-Dry Wireless Mini comes in at an astoundingly low price, without sacrificing too many features.
Notably, this unit can run for 20 to 30 days before you need to recharge its silica beads, meaning you can set it and forget about it. It’s a great way to avoid the usual tank emptyings that other dehumidifiers may require.
The design, centered around the silica within the unit, is completely free of cords and wires and does not require any batteries. It’s as easy as popping it open and hanging it in whatever room you want. It’s also extremely sleek and small.
However, this model is not as powerful as other dehumidifiers. It only leeches out 6 oz. throughout the time it runs, so don’t expect it to turn a swampy room into a desert.
It works well for most small rooms, such as closets, boats, and cars. If you live in a humid area and need to keep your guns dry, place one of these in your gun safe or gun closet to reduce corrosive moisture. It comes with a 5-year warranty policy that can keep you happy and dry for a long time to come.
- Spill and mess-free
- Capable of running for a very long time
- Small and elegant design
- Low absorption capacity
Who Should Get This?
If you’re looking for a cheap dehumidifier that will do the trick in small rooms while running for a long, long time, this model is for you.
- Thermoelectric cooling technology
- 2nd generation model
- Auto shut-off feature

Bathrooms can be particularly damp places, given the fact that there’s a lot of water from showers and the sink. That’s why you need a LONOVE Dehumidifier capable of tackling this high level of moisture.
I recommend this unit for that purpose because of its highly efficient dehumidification, which is capable of keeping ambient water levels at 45% or below. It also has a 1-liter water tank minimizing the amount of time you’ll need to empty it, especially given that it drains only 350 mL of water per day.
Despite this lower water drainage rating, it’s still suitable for covering rooms of up to 190 ft2, which will likely satisfy all but the most extravagant of washrooms.
If used outside the bathroom, it works great for keeping your furniture dry, extending their lifespan by preserving their durability.
As you’re operating a dehumidifier and not a spaceship, the 1-button control system is perfect. After all, what you need is easy operation and not overly complicated interfaces.
LONOVE has learned from its earlier models and has excelled here in creating an effective and easy to use dehumidifier that’s well-suited for even the dampest of environments.
- High-efficiency dehumidification function
- Easy to clean
- Eliminates bad smells
- Lower water drain rate
Who Should Get This?
Are you sick of your bathroom being all steamy and muggy after you use it? This dehumidifier can keep things dry and comfortable.
- 20 oz. tank capacity
- 10 oz. drained per day
- Dimensions: 5.75” x 5.75” x 8.94”
- 199 ft2 of dehumidifying action
- 2.2 lbs. weight
For a bedroom environment, you typically want a dehumidifier that can run quietly, which blends well with the furniture. The Honati Small Dehumidifier succeeds on both these counts.
While it’s not the quietest model on the block, it does run softly enough that it works as white noise while you’re resting. The LED light design makes it look more like a smart home device than a dehumidifier. As a result, you won’t have to worry about it clashing with your room’s decor.
It can handle environments with a relative humidity of 80%, so it works for even the dampest of conditions like a basement. It’s excellent for rotten floors and wet clothes and can help with conditions as diverse as rheumatism and allergic rhinitis.
One thing we didn’t like as much was operating the tank. Taking it out of the unit is somewhat complicated and requires popping open a lid, which you will have to reattach before you can continue using the unit.
However, if that was the biggest complaint we could muster, this model is very impressive and guaranteed to be satisfying.
- Futuristic technological design
- Great for reducing illness symptoms
- Fits nicely on a nightstand
- Slightly inconvenient tank emptying mechanism
Who Should Get This?
Is your bedroom missing a dehumidifier? Choose this model if you want a unit that’ll blend in well with the local decor while keeping your room pleasantly dry.
- 350 grams of silica
- Ideal for spaces up to 53 ft2
- Unique cylinder shape
- No-leak, no-spill design
- Transparent visualization window
This unit is so small that it can fit anywhere, whether it’s a room, a safe, or even a gym bag. It’s the perfect example of a small space dehumidifier.
It operates using small silica gel crystals, a far cry from the more common thermo-electric systems. Its cylinder shape means that more surface area is available to absorb moisture, improving the rate at which it dries the surrounding air.
This unit can function for 2-3 weeks of absorption, and you can tell it is full when the silica beads turn dark green.
When full, they can be recharged by simply plugging the unit in. While this is convenient, it’s, unfortunately, let down a bit by the long charging time – you’ll need 12 to 15 hours to dry out the silica gel beads effectively.
Another exciting feature of this dehumidifier is that it’s completely recyclable. Because the material is entirely non-toxic, safe, and spill-free, it can easily be thrown into a recycling bin when you’re done with it.
That won’t be for a while since these models are built to last. Rest easy (and dryly) with this unit.
- Fits virtually anywhere
- Easy plugin and recharge function
- Large surface area for absorption
- Slow recharge time
Who Should Get This?
This unit is the right one to pick if you have a very small area that you need to dry. You’ll also enjoy the long runtime and wire-free design.
- Air blows out the back
- Dimensions: 7” x 4.9” x 11”
- Easy tank removal
- Weight: 4 lbs.
The great thing about this unit is that it comes with adjustable humidity controls. It’s capable of detecting the current relative humidity before dehumidifying the air down to whatever percentage you want it to. Once it hits the targeted level, it’ll automatically turn off, making it perfect for rooms where you want a precise amount of moisture in the air.
However, be aware that it operates best in warm and humid spaces.
Another thing we noticed was how fast it filled up. In just 3 days, nearly ¾ of its 1.5-liter tank filled up, and we saw the difference in the air almost immediately.
The unit itself is very sleek and compact looking. The design is super portable, so you can bring it anywhere and look good doing it.
It’s also energy efficient. The built-in thermoelectric peltier module uses minimal energy, and it has an ETL-certified 36-watt adapter, which prevents overheating and energy waste.
Some reviewers reported that the unit needed replacing after just a month or so, while others were satisfied with it for longer durations. The low price point means that this model is worth a try in your home.
- Affordable price point
- Automatic shut-off
- Easy to carry around
- Issues with longevity
Who Should Get This?
This is a relatively affordable unit that’s both portable and sleek looking. Get it if you need performance and convenience in one package.
- Powerful built-in compressor
- Dimensions: 12.2” x 8.2” x 18.9”
- Light-touch intelligent control panel
- Weight: 23.8 lbs.
- 2 fan speeds
The Yaufey 30 Pint is halfway between being a small dehumidifier and a medium-sized one. The small dimensions imply it’s a compact unit, but its power and features belie the performance of a larger model.
Suited for spaces of up to 1,500 ft2, it is capable of removing up to 4 gallons of ambient water in a day, which easily blows past other small models. Of course, this power comes at a price.
The unit is considerably more expensive than other entries on this list, but its feature set makes it well worth the asking price.
For instance, it includes a drainage hose, which you can connect and set up so that the water continuously empties. This function removes all the hassle of emptying a tank and allows it to run perpetually, without interruption.
It also has a programmable timer and lots of user control over the fan settings, ranging from turbo, for maximum dehumidifying power, to the quieter normal mode.
Overall, this model is a solid pick at a slightly premium price.
- Do not need to empty tank
- Versatility in functions
- Extremely powerful dehumidification
- Very high price
Who Should Get This?
This unit’s right on the cusp between small and medium dehumidifiers. It’s great if you need dry air in a space that’s slightly larger than what other small models can handle.
- High-efficiency porous design
- Weight: 1.38 lbs.
- 23W used per hour
- Removes up to 300 mL daily
- 700 mL tank capacity
These models often come in a standard white, so it’s a breath of fresh air to see a sleeker-looking black model. It’s not just the color that stands out. The whole design is very high-tech, with an LED light button and a smooth contour that lends it the feel of much more expensive pieces of technology.
Of course, aesthetics is one thing, while performance is another, more important factor. This unit can cover 215 ft2, partly due to a surrounding porous design that allows for maximum local dehumidifying.
It also features a 1-touch switch that makes operation simple.
Safety isn’t an issue for this model. It shuts off automatically when the tank is full, conveniently letting you know that it’s time to empty it. The semiconductor cooling technology uses absolutely no chemicals, so there’s no risk of harming your children or pets.
Even better, this package is an extraordinarily low price. You can get solid value, good performance, and beautiful looks all in one. What are you waiting for?
- Large surface area for maximum moisture absorption
- Very safe design
- Lower energy consumption
- Need spaces around inlets and outlets
Who Should Get This?
This unit will do the trick for those who are tired of boring white dehumidifiers. It performs well and is completely safe for use, especially with its chemical-free cooling technology.
- Optimal operation in 60%+ relative humidity
- 1-year warranty policy
- Free replacement service
- Touch control system
- Remote control included
While this unit comes in at a slightly higher price point than some others, it backs up its cost with more substantial dehumidifying power.
It can handle 269 ft2 spaces, and it can remove 17 oz. of water a day, which is strong performance for a small unit. It can even dry out the air up to 40% relative humidity, although it operates best at 60% and above.
Also included is an array of modes that you can select through its smart touch control. By looking at the LCD, you can choose to enter sleep mode, defrost mode, or even a constant humidity setting. Whatever the situation you encounter, there’s an option to handle it.
You can control it from a distance, which adds to this model’s convenience factor. There’s also a drainage hose that lets the water out without continually needing to swap out the tank.
We can’t go on without mentioning just how quiet this unit runs. It’s perfect for bedrooms or any room where you need to work without distraction. We also think this unit would work well in an office setting where you can access a window for the drainage hose.
- Lots of different modes to use
- Great build quality
- Smart timing functionality
- Slightly higher price point
Who Should Get This?
You should consider this unit if you want an ultra-quiet model that still does the job of dehumidifying. You’ll also appreciate all the extra features.
How to Choose the Best Small Dehumidifier?
There are several factors to consider when it comes to choosing the right dehumidifier.
Size is determined by your unit’s total moisture removal capacity making it a critical element of any dehumidifier. This capacity is generally rated in pints of moisture removed per day, but it can also show up as ounces or milliliters. Regardless of the measurement used, the dehumidifier’s strength is directly tied to the amount of water it can remove from the air.
There may also be ratings for how large a room it can cover, so make sure to factor this in before purchasing.
Start by asking yourself how damp the space is. If it’s exceptionally wet, you likely need a stronger dehumidifier covering a larger radius than the room. You might also need this power if you have multiple people in the space or several doors and windows in the area.
If it’s only a little moist, you’ll likely be okay going with the recommended room dimensions.
For the largest models that plug into your HVAC system, you likely won’t have to worry about draining by hand, as typically these will come with features that drain the excess moisture to a sink or the outdoors.
As for more portable models, there are 2 ways that water collection can work.
The first one is via a tank or installed bucket. In this case, you’ll have to remove the water tank and empty it before putting it back in the unit.
The other option for water collection and drainage is a drain hose. This hose automatically empties the collected water into a sink, bucket, or floor drain of your choice.
It’s up to you to decide what you want.
How much energy you’re using can be tied to electrical bills and other expenses.
The best way to determine energy usage is by looking at the unit’s rated voltages and wattages. Higher numbers mean more energy usage, so you’ll typically want the lowest figures that can still perform as you need it to.
Another thing to keep an eye out for is Energy Star certifications. If certified, the dehumidifier uses 15% less energy than conventional units, saving roughly $175 over the unit’s lifetime, or approximately 2,800 lbs. of greenhouse gas emissions.
Method of Dehumidification
The most common type of dehumidifier uses refrigerated coils. These units suck in moist air through a grill, with a fan drawing the air further inward. It passes over cold pipes, causing the air to cool. Any moisture solidifies into water, which passes down over the coils and into a tank. The dried air passes through a heating element and is blown back into the room.
This system requires that you empty the tank regularly and has more moving parts that are prone to breaking or needing replacement.
Other dehumidifiers can use absorption. They will have material inside, like silica, that holds water. Moisture in the air will be absorbed or picked up onto the surface of the material.
These units are cheaper and less likely to need maintenance, but they also don’t dehumidify effectively.
Final Verdict: Our Top Choice
If you’ve made it all this way, then you likely already have some idea of what dehumidifier you want to get. We believe that the Pro Breeze Mini is the ideal unit for almost any home or office space.
It’s got a solid 18 oz. tank that lets it run for up to two days of dehumidifying before it needs to be changed. It’s able to do this efficiently for a space of 150 ft2.
The unit’s also got an auto shut-off function that lets you know right when it needs filling, minimizing downtime.
It checks off all the boxes most people are looking for in a dehumidifier, AND it comes in at a reasonable price point.
