Product Reviews

As we searched for the best small dehumidifiers, our expert team put each unit under a microscope to ensure effectiveness. We selected these seven products based on customer feedback and product specification.

We looked closely at features, capacity, room coverage, and more.

1. Seavon Dehumidifier for Home 2200 Cubic Feet

Best Coverage

Just because a dehumidifier is small doesn’t mean it needs to be inefficient. The Seavon model covers a room up to 260 square feet. It extracts up to 350ml per day, which is quite the achievement for such a compact option.

If you’re looking for healthier air, this is a great budget-friendly choice for your home. It’s also a quiet option that doesn’t exceed 35 decibels. So you can take soothing naps with this device in the same room.

What We Like

Green Red Indicator Lights

The handy indicator lights can tell you what’s happening with the device. Firstly, a green light lets you know the unit is working. The red light means that the unit is full, and it will turn off automatically. This takes some of the guesswork out for you.

User-Friendly Design

The one-button control makes this a super user-friendly device. There are not a ton of different steps and buttons you need to press to turn on the unit. It’s super convenient and easy to use.

Portable and Compact

Move this compact unit from room to room with total ease, thanks to the portable handle design. The built-in handle makes it easy to move around without spilling any water.

Keeps Moisture Below 45 Percent

For such a small device, this is a big claim. This dehumidifier can extra 350ml of water daily, keeping levels below 45 percent, which benefits our health.

800ml Water Tank

You can empty this less often since the water tank can hold 800ml (27 ounces) of water. If you use this daily, you only need to empty the tank every other day.

What We Don't Like

Not the Most Effective

Some customers found that this wasn’t effective enough. Even after running the dehumidifier for an entire day, there wasn’t much water in the tank. Perhaps their homes weren’t that humid, but perhaps, compared to other options, this isn’t the most effective.

Cord Overheats

One safety concern is that a few customers found that the cord overheats sometimes. You may not want to leave the unit unattended.

Product Specs

Dimensions 9.88 by 6.26 by 4.49 inches
Weight 1.69 pounds
Recommended Room Coverage 55-260 square feet
Moisture Removed Per Day 27 ounces
Warranty  12 months

2. Seavon Small Dehumidifier

Best Reservoir Capacity

If you liked the first on our list but wanted something a little larger, this is it. This dehumidifier is small and compact, but not to be underestimated. It has a large reservoir that can hold up to 35 ounces of water vapor.

Consumers love how quietly it operates and how effective it is. It’s super simple to use and doesn’t contain a lot of complicated buttons.

Seavon has covered the dehumidifier with a one-year warranty.

What We Like

For Small to Medium-Sized Rooms

If you need a dehumidifier for small to medium-sized rooms, this is your guy. This is slightly bigger than the previous unit on our list and can remove up to 35 ounces of moisture per day. It’s excellent for living rooms or laundry rooms where dampness can cause trouble.

Quiet Operation Below 30 Decibels

This dehumidifier uses Peltier technology that won’t have you grasping those earplugs. It’s ultra-quiet with noise levels below 30 decibels at low-speed mode. You can even use it in a bedroom during the night or children’s room without noise complaints.

Safety Feature Prevents Leaks

This unit has an auto-shutoff function that prevents over-flooding of the tank. Whenever the reservoir begins to fill up, the feature will turn the unit off and notify you simultaneously. Once the tank is emptied, the unit will run as usual.

Seven Changing Lights

This unit has a fun feature that might benefit you. It has seven light color options so that you can choose the right one for the atmosphere. For instance, bright blue is distracting at night but fun during the day.

Built-In Handle

When you need to move this around, it’s easy. First of all, it only weighs around two pounds. But it also has a built-in handle so you can easily transport it from room to room.

What We Don't Like

Power Cord Heats Up

The power cord gets warmer when used. This is a minor fault that some might not notice. They even have to put it on the notice, but this is not alarming at all.

Short Lifespan

The warranty is 12 months, and thank goodness for that. Many customers reported that their unit died after six months. If you want something more durable, and don’t want to deal with customer service operators, you might want to choose another option.

Product Specs

Dimensions 6.3 by 6.3 by 10 inches
Weight 2.19 pounds
Recommended Room Coverage 285 square feet
Moisture Removed Per Day 35 ounces
Warranty  12 months

3. Afloia Gun Safe Mini Dehumidifier

Best Portable Dehumidifier

Operating a dehumidifier doesn’t get much easier than this. The Afloia dehumidifier is super simple to use as you only need to place it on areas where you need to keep the moisture at bay, no buttons whatsoever.

It has a sleek and modern look that suits any room because of its design.

It works very quietly due to not having a compressor. You can easily use it in a bedroom, nursery, office, or other living areas without feeling bothered.

What We Like

Lightweight and Easy to Move

You can easily take this dehumidifier with you wherever it’s needed. It’s very lightweight, weighing only 1.01 pounds, so it’s a breeze to move between rooms.


You’ll like this feature if you’re a forgetful person or worry about overcharging the silica beads. The auto-shutoff will turn the heating base off, two hours after charging, despite placing the dehumidifier stick on top of the heating base. This feature automatically enters standby mode post charging.

Efficient Dehumidification

The cylindrical design of Afloia makes it an efficient moisture-absorbing machine by having 360-degree air inlet.

What We Don't Like

Slow Results

If you have a significant amount of moisture or dampness in a room, you shouldn’t expect results straight away. Customers noticed that it requires a little while if there’s a lot of moisture in the air.

Product Specs

Dimensions 3.74 by 3.74 by 4.57 inches
Weight 1.01 pounds
Recommended Room Coverage 54 square feet
Moisture Removed Per Day 4oz/100ml per cycle
Warranty Not specified

4. Pohl Schmitt Mini Dehumidifier

Best for Allergies

If you need a small dehumidifier to help with allergies, this is it. Many homeowners favor this little device from Pohl+Schmitt due to its size and efficiency.

It will effectively keep mold, mildew, and dust mites at bay by creating an environment that doesn’t support these allergy triggers.

It works quietly and is hardly noticeable, making it an excellent choice for bedrooms or nurseries.

The light design also makes it easy to move around where it’s most needed.

What We Like

Fits on a Small Table

Thanks to the compact design, this dehumidifier is easily located anywhere needed. It fits perfectly on any small bedside or coffee table without trouble. It’s also lightweight and is a breeze to carry around so that you can enjoy less humidity in every room.

Effectively Removes 10 Ounces Daily

Despite the small size, this dehumidifier is highly effective. It’s equipped with a 17-ounce tank and will remove up to 10 ounces of moisture daily.

Quiet Operation Suitable for Nighttime

You can easily use this compact device in your bedroom during the night without compromising a good night’s rest. It doesn’t have a compressor, which makes the operation ultra-quiet for an even more comfortable atmosphere.

Safely Designed Without Harmful Chemicals

This dehumidifier is an excellent choice for a family with small children. The Pohl+Schmitt team carefully manufactured the unit without any harmful chemical substances.

What We Don't Like

Slowly Extracts Moisture

If there’s a lot of moisture or dampness in a room, this tiny unit will need some time to fix it. It works efficiently but is best in smaller rooms.

It Doesn’t Significantly Reduce Humidity Level

While it does work in small spaces, it runs slowly. This means that it won’t effectively get your humidity levels to an ideal amount. Many customers found that it could drop them by around five percent.

But if you’re trying to get from 60 percent to 40, it might never reach it.

Product Specs

Dimensions 11.18 by 6.38 by 5.2 inches
Weight 2.53 pounds
Recommended Room Coverage Small rooms
Moisture Removed Per Day Not specified
Warranty Not specified

5. Pro Breeze Mini Electric Dehumidifier

Most Convenient Small Dehumidifier

One brand that’s often mentioned when it comes to small dehumidifiers is Pro Breeze, and it isn’t difficult to see why.

This compact unit was designed to be convenient and easy to take wherever needed. It can handle rooms of up to 150 square feet. Plus, it will remove a significant amount of moisture during each cycle.

The Pro Breeze is also equipped with an auto-shutoff to prevent water overflowing when the reservoir is full. It will quickly turn the unit off when the tank becomes full.

What We Like

Effectively Removes Nine Ounces Daily

Despite the small size, this dehumidifier packs a big punch. It will effectively remove up to 9 ounces of moisture per day.

Pro Breeze recommends that it be used in a room of up to 150 square feet with a temperature between 59 and 86 degrees Fahrenheit. The reservoir has a capacity of 16 ounces, which isn’t the biggest but impressive for such a small unit.

Nearly Silent

This dehumidifier was designed using a built-in thermoelectric cooling technology called Peltier. This enables the unit to effectively draw moisture from the air without a compressor.

Because there’s no compressor, the unit is ultra-quiet and suitable for a bedroom or nursery without causing trouble.

Easy to Empty the Reservoir

One thing we dislike about dehumidifiers is how tricky it can be to remove and replace the reservoir.

However, Pro Breeze has made it a literal breeze to empty by placing the reservoir at the front of the unit. You can easily slide it out when it becomes full and slide it right back into place when empty.

Compact and Portable

You can place the Pro Breeze nicely on a small table or countertop. You can even use it in an RV, boat, or your office. Not only is the design compact, but it’s also lightweight, clocking in at only 2.4 pounds.

What We Don't Like

Tank Fills Up Fast

Unfortunately, due to the small reservoir, it tends to fill up rather quickly. This does, however, depend on how humid the area is.

Removes Moisture Slowly

This isn’t the best option if you want to reduce humidity levels quickly. After a week of running this device, your humidity levels may still not be where you want them. This is especially true if you live in a super humid area.

Not the Most Durable

Thankfully the warranty is 12 months because many customers reported this dehumidifier dying out after just a few months.

Product Specs

Dimensions 7 by 6 by 11 inches
Weight 2.4 pounds
Recommended Room Coverage 150 square feet
Moisture Removed Per Day 9 ounces
Warranty 12 months

6. Vavsea Energy Dehumidifier

Best Budget-Friendly Dehumidifier

If you’re on a budget, this dehumidifier will suit you just fine. It’s light and compact and fits in any small room or area.

The Vavsea is super simple to operate since there’s only one on/off button. The tank is easily removed by sliding it out.

When the tank is full, a light on the display will notify you that it’s time to dump the contents.

What We Like

Compact and Quiet

The size of this dehumidifier is what makes it so unique. It’s compact and lightweight, yet durable and efficient. You can easily move it from room to room where you might need it, and it fits in any tight space.

Another benefit of this unit is how quiet it is. It doesn’t have a compressor and is, therefore, super quiet. You can use it during the night in your bedroom or even at the office without worrying about noise.

Energy-Saving Technology

Thanks to Peltier technology, this dehumidifier is also energy efficient. It uses minimum energy as it operates, so you won’t have to worry about it increasing your bills.

Excellent for Small Spaces

This dehumidifier is best used in small rooms of up to 215 square feet. It’s equipped with a 17-ounce reservoir and collects up to 17 ounces of water daily.

Translucent Reservoir

Knowing when to empty the tank can be tricky. Luckily, the Vavsea dehumidifier is equipped with a colored, translucent tank that helps you to see when it’s full. If you don’t notice it, the device will automatically turn off when full, thanks to the auto-shutoff function.

What We Don't Like

Must Be Used in Closed Areas

This dehumidifier is most effective when in a closed, small room. So if your home is designed with open rooms and areas, it might not work as efficiently.

Not the Best for High Humidity Areas

If you live in a high-humidity area and need quick results, this won’t be the best option for you. Even if you place this in a tiny space, it can take too long to bust moisture out of the air.

Product Specs

Dimensions 6.06 by 5.11 by 8.58 inches
Weight 1.06 pounds
Recommended Room Coverage 215 square feet
Moisture Removed Per Day 17 ounces
Warranty 1 year

7. Eva-Dry Renewable Mini Dehumidifier

Best Non-Powered Small Dehumidifier

If you’re looking for a dehumidifier that can be used in small rooms and requires no power outlet to work, this is it. The Eva-Dry Renewable Mini Dehumidifier requires no batteries or electricity to work. You simply place it in an area, and it will work.

It’s filled with silica gel: what we usually find in product packages to keep moisture at bay. The beads won’t spill or leak, so it poses no risk for danger in a family home. We love that it can be renewed, so you don’t have to purchase refills.

This mini dehumidifier will only work in areas of up to 48 square feet. You shouldn’t expect it to work in larger rooms. We highly recommend it in small bedrooms, closets, cars, or RVs.

What We Like

Requires No Batteries or Power

This mini dehumidifier is different from regular dehumidifiers; it uses no batteries or power whatsoever. It uses silica gel that effectively absorbs moisture in a humid area. The silica gel will work for up to two to four weeks, depending on the conditions.

Color-Changing Crystals

Because this dehumidifier doesn’t use batteries or any power, there’s no light indicator of when the silica gel needs renewal. However, the crystals will change color from orange to green. So you’ll have to check the beads through the transparent part of the device.

Renewable Beads Save You Money

Unlike other similar mini dehumidifiers, this one is renewable. That means you won’t have to purchase expensive refills. All you have to do is keep an eye on the color of the beads; once they change to green, it’s time for renewal.

You do this by plugging it into an outlet in a well-ventilated room. It will take between eight and 10 hours for it to renew. Once the beads have changed back to orange, it’s ready to be used again.

Long-Lasting (10 Years)

You might think that this process can’t go on for long before the beads won’t be able to renew. But think again, the Eva-Dry silica gel can repeat its renewal process for up to 10 years. This depends on environmental conditions and if the device is used correctly, but you can trust that it will last you for years.

Safe for Homes With Kids and Pets

If you have small children or pets, using a device with silica gel might seem worrisome. However, the Eva-Dry won’t leak or spill, even at full capacity. Every drop of water vapor the gel catches will be trapped within the beads, unable to escape until it’s renewed.

What We Don't Like

Only for Small Spaces

Although this dehumidifier works efficiently, it will only do so in small areas. These include spaces such as a closet, bedroom, or even a car. You shouldn’t expect it to make much difference in large or open areas.

Easy to Accidently Open

The main design flaw is a hook on the fill port. So if you go to hang the device or twist the hook, you’ll accidentally open the port. Beads will spill everywhere, and you’ll have to buy a new device or find replacement beads.

Product Specs

Why Choose a Small Dehumidifier?

Small dehumidifiers are obvious choices for small rooms and areas, but that’s not all they’re good for. Regular dehumidifiers can be expensive, large, heavy, and noisy. This could make them tricky to use while you’re in the room.

Due to the comfortable noise level, we prefer small dehumidifiers over regular dehumidifiers in common living areas. What makes them quieter is the technology used, which is called Peltier. This is used instead of the usual compressor, which makes significant noise.

Despite this, small dehumidifiers also have a few downsides. One is that they generally don’t function as well in colder temperatures (below 41 degrees Fahrenheit).

Another flaw is limited capacity — usually, reservoirs can hold anything under 20 ounces, depending on the device.

What to Look For (Buying Guide)

Finding the best small dehumidifier for your needs can be tricky with such a wide variety available on the market. So we’ve created a helpful buyer’s guide to point you in the right direction.


We already know we want a small dehumidifier, but the size is still something to consider. If you need a dehumidifier for your large basement, size might not matter. However, if you need one for your bedroom, bathroom, or closet, space will be compromised.

Small dehumidifiers come in different sizes. Some fit on a bedside table, while others stand subtly in the corner of a room.

Before choosing a unit, consider where you’d like to use it. A compact, lightweight dehumidifier is an excellent choice for mobile homes or offices. On the other hand, a slightly larger unit is great in bedrooms, laundry rooms, and bathrooms.

The best way to consider the size is by checking the unit’s dimensions.

Room Coverage

Room coverage is an essential factor to look for when searching through possible dehumidifiers.

Small dehumidifiers usually cover up to 150 square feet, with slightly larger models covering a little over 200 square feet. This is nothing compared to large units that can cover areas of up to 2,000 or even 4,000 square feet. It’s essential to keep this in mind, so you don’t end up disappointed.

Reservoir Capacity

The reservoir will collect all water vapors in the reservoir. Again, due to the small size, the tanks are on the small side, which we explained above.

When choosing a unit, consider how humid your home environment is. A small reservoir will need to be emptied often when used in a high humidity area. In this case, going for a larger reservoir would be more practical.

We recommend looking for something over 20 ounces, but some brands go higher, up to 35.

Safety Feature

As you look at small dehumidifiers, you might notice how simple they are. Large units usually come with an LED display with many modes, settings, and options. However, most small dehumidifiers generally only feature an on/off button.

Safety Feature Explained

One important feature of the best small dehumidifiers is an auto-shutoff function. This function will automatically turn the unit off when the reservoir becomes full — avoiding water overflowing the tank and causing damage.


Do Dehumidifiers Use a Lot of Electricity?

Dehumidifiers do not use a lot of electricity. Most models use the equivalent electricity of using your dishwasher for half an hour or running your laptop.

Where is the Best Place to Put a Dehumidifier?

The basement is the best place to put a dehumidifier because they are typically damp environments. Removing moisture from the basement reduces the chances of mold spores traveling around your home.

Are Portable Dehumidifiers Effective?

Portable dehumidifiers are effective because you can place them directly in the spaces where mold and humidity are an issue. It also helps you to tackle mold on a room-by-room basis.

Will a Small Dehumidifier Work In a Large Room?

A small dehumidifier will struggle to work in a large room because it lacks power or capacity. While it will reduce moisture levels, it will never reach the optimum 30 to 50 percent humidity needed to control mold growth.

How Long Does It Take for a Small Dehumidifier to Work?

A small dehumidifier will take a couple of days to a week to work, provided you have sized the dehumidifier correctly to cope with the room dimensions.
