Don’t judge a dehumidifier by its size.

Having a dehumidifier is essential for many homeowners dealing with a significant amount of moisture. However, dehumidifiers tend to be quite cumbersome. This might be challenging to find a suitable location or even impossible to use in small spaces.

Luckily, there’s an easy fix to this problem. Small dehumidifiers can be highly effective in small rooms such as laundry rooms or nurseries.

If you’re on the hunt for a small dehumidifier, you’ve come to the right place. Everything you need to know about buying the right size and model for you can be found here. We’ve got the best of the best small dehumidifiers on the market.


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.

We prefer small dehumidifiers in common living areas due to the comfortable noise-level. What makes them quieter is the technology used, which is called Peltier. This is used instead of the usual compressor which makes a significant amount of noise.

Peltier technology is also referred to as thermoelectric. It works by absorbing heat on one side and then evaporating it on the other side. So one side heats up while the other stays cool. This temperature difference promotes dehumidification (1).

This technology is commonly used in devices that are too small for a compressor. It’s also a very reliable technology since there are no moving parts that could break. Compressors will usually cause vibrations and 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.

Finding the Best Small Dehumidifier for You

Living in a humid area can cause your house to feel and smell musty and damp. It can cause mold and mildew to grow and create the perfect environment for common allergy triggers like mites. Luckily, having a small dehumidifier can make a significant difference.

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.

Size

We already know that 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 are designed to easily be placed 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. A slightly larger unit, on the other hand, is great in bedrooms, laundry rooms and bathrooms.

Room Coverage

Room coverage is an essential factor to look for when searching through possible dehumidifiers. It’s important to understand that due to the small size of these units, they won’t be able to cover large or open rooms.

Small dehumidifiers will 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

Another thing to consider is the reservoir capacity; this is where all water vapors will be collected. 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.

Safety Feature

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

Take Note

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.

A red light on the display will light up to notify you that it’s time to empty the reservoir. Simply take it out, empty the tank and place it back into the unit.

Keep In Mind

Bright LED Light

At the top of the unit, there’s a bright green LED light whenever the dehumidifier is on. This can cause a few issues for anyone who uses it during the night since it can be bothersome. However, many customers said it doubled as a night light, so it comes down to personal preferences.

Check Price

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 from overflowing when the reservoir is full. It will quickly turn the unit off when the tank becomes full.

Why We Love It

Effective

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’s 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, also known as 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 can easily be used in a bedroom or nursery without causing trouble.

Easy to Empty

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

The Pro Breeze can easily be placed on a small table or countertop. It can even be used 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.

Compact and Quiet

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

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.

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 showing up on your bills.

Keep In Mind

7. Eva-Dry Renewable Mini Dehumidifier

Best Non-Powered Small Dehumidifier

Eva Dry Wireless Mini Dehumidifier. Top Moisture Absorber for Small Spaces. Rechargeable & Portable. Perfect for Bedrooms, Closets, Cars, RV & Gun Safes. Removes Humidity & Helps Prevent Mold Growth
Check Price

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 be used in small bedrooms, closets, cars or RVs.

Why We Love It

Requires No Batteries or Power

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

Color-Changing

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

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

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 does depend on environmental conditions and if the device is used correctly, but you can trust that it will last you for years to come.

Safe

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 when at full capacity. Every drop of water vapor the gel catches will be trapped within the beads, unable to escape until it’s renewed.

Keep In Mind

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 car. You shouldn’t expect it to make much of a difference in large or open areas.
