First on our list is one of the most popular dehumidifiers ever. The Eva Dry Mini is a classic. It is a desiccant dehumidifier that works with silica gel and runs wirelessly.

This unit can work in any enclosed space up to 333 cubic feet. Once the device is charged, hang it back up and leave it until the next charge.

Unlike a typical mini dehumidifier, it does not collect moisture and doesn’t come with a water tank. However, it can absorb up to 6 ounces of water before the orange silica gel beads turn green.

So, if you are struggling with excess moisture in a small room, you may want to skip this one.

This portable dehumidifier works without batteries or power, and you can use it in any small space, including gym bags, gun safes, boats, and RVs.

It also spills and leak-proof, thus making it safe to put around children and pets. Given its small size and limited capacity, you would expect this device to stop working in a short while, but you’d be wrong.

The E-333 comes with an industry-best five-year warranty and has a lifespan of 10 years! That is nearly three times as long as the average electric dehumidifier.

This long-lasting mini dehumidifier is not only a universal favorite but also the cheapest on our list.


  • Wireless
  • Eco-friendly
  • Long life span
  • Great warranty
  • Easy to use


  • Long recharge time
  • It only works in small spaces.

The next item on our list is a mini dehumidifier that delivers value for every dollar spent on it. The SEAVON Electric Dehumidifier comes with a 16oz water tank and can withdraw 10 ounces of water per day in 86°F, 80% RH.

This unit can handle any small room up to 205 square feet. The device uses thermo-electric cooling technology (Peltier); thus, it does not rely on a compressor. As a result, the noise output is just 39 dB.

The whisper-quiet operation means you can use it in a baby’s room or have it beside you during your Zoom meetings without any disturbance.

Another advantage of this portable machine is the auto shut-off function. Once the water tank is full, this thermoelectric dehumidifier switches off, and the LED turns red.

Given its compact size, there are, of course, a few limitations. The major one is the weather conditions. The optimal temperature needed for the device is 59-86°F, and it will not work below 41°F.

However, this is a common problem with mini dehumidifiers and not this model alone. It is also worth mentioning that SEAVON has high-speed customer service.

This unit comes with a decent warranty (two years), which might look small compared to Eva-Dry, but it is undoubtedly better than most.


  • Noiseless operation
  • Auto shut-off
  • Decent warranty


  • Not useful in winter
  • Basic design

3. ALROCKET Dehumidifier  – outstanding all-round performance

No products found.

This is another bestselling mini dehumidifier with the performance to back it. It comes with a 35 oz water tank and can extract 16 ounces of water per day in optimal conditions (86°F and 80% RH), so you only have to empty the water tank every two days.

This compact model is designed to work in room sizes between 54 and 260 square feet, which is significantly larger than the two previous dehumidifiers we’ve reviewed.

It also uses Peltier technology like the SEAVON mini dehumidifier, which whispers quietly at 39 dB. So if you care about energy consumption (and we hope you do), then the Alrocket won’t let you down.

It consumes just 40W/hour or 0.96kW in 24 hours. As if that wasn’t enough, this unit boasts a wider optimal temperature operating range than most mini electric dehumidifiers, of 41°F-122°F.

Even though it does not work below 41°F, it is still impressive, considering only desiccant dehumidifiers can function well in cold temperatures.

Even though this system has a decent tank capacity of 35 oz, it shuts off when the water level is between 24-27 oz to prevent spilling. When this happens, a red LED light comes on.

Speaking of lights, there are seven light colors to choose from, which you can set using the button on top of the unit.

Something we also like about the Alrocket is its appearance. If looks could kill, this would undoubtedly be the best dehumidifier on our list.


  • Decent capacity and coverage
  • Attractive design with different color lights
  • Can work in harsh weather
  • Quiet operation


  • Relatively small water tank

4. Home Dehumidifier – large yet portable

No products found.

Now we come to the biggest thermoelectric dehumidifier on our list. At 8.98 x 5.9 x 14.65 inches, this relatively large tech piece comes with high expectations for water removal, and it delivers.

The Honati dehumidifier has a 67oz water tank and can remove 25 oz of moisture per day from small spaces (100 – 269 square feet) at optimal conditions.

That is more than double the capacity of the Seavon and significantly more than Pro Breeze, which has the second-largest water removal rating on our list.

Despite being a powerful electric dehumidifier, it still maintains a low noise level of 39 dB, making it an excellent feature for bedrooms, closed kitchens, offices, and kids’ rooms.

As expected, it has an auto shut-off function to prevent spillage. Even though it is larger than the other units being reviewed, it still weighs under 6 pounds, making it incredibly portable.

It is also energy-efficient, consuming just 40W per hour. Where this dehumidifier loses marks a bit is in the temperature range, which is the standard 59-86°F.

If it could perform as well as the Altrocket, then it would have been the winner. But, again, this temperature limit is insufficient, just not enough to make it the best dehumidifier within our price bracket.


  • Large capacity with a high moisture removal rate
  • Quiet operation
  • Can handle slightly larger rooms
  • 30-day money-back guarantee


  • Users have commented that it is a bit shaky, so it’s best to place it on a sturdy surface or next to a wall.

Simply empty the water tank and place it back into the dehumidifier.

  • Ultra-Quiet & Efficient Dehumidifiers for Bedroom: Built-in Thermo-Electric Cooling Technology (Peltier) operates without a compressor providing whisper quiet operation in bedroom, bathroom, and office.

  • Lowers Humidity: This dehumidifier functions as a moisture eliminator in areas with high humidity like your home, kitchen, bathroom, bedroom, RV, garage or closet. Like all mini dehumidifiers, optimal operating temperature is 59-86°F. It will not work below 41°F.

Many people consider this the best dehumidifier or the best thermoelectric dehumidifier, and there is a strong case for it.

The compact Pro Breeze Electric Mini comes with a 52 oz tank and can remove 18 oz of water per day in a room up to 250 square feet.

This means it can remove more moisture from the air and at a faster rate than every other device on our list except the much larger Honati.

You can begin to see why it is more expensive. However, its other features are what we have come to expect from our top contenders.

For example, the ideal temperature performance range is 59-86°F, and it cannot work below 41°F. In addition, it uses Peltier technology, so it is quiet and lightweight, making it a good addition to any small room.

However, what is unusual is that several users have attested that this unit works well in rooms much larger than recommended, in some instances as much as three times the size suggested!

That is not to say you should do the same thing or that we approve of it for such use. However, to make the most out of any dehumidifier, you should follow the instructions.

If you want a cheaper alternative, Pro Breeze also has a 16oz version that is nearly half the cost.


  • The impressive moisture removal rate
  • Can handle larger rooms
  • Quiet operation


  • A bit pricey
  • Basic packaging in terms of look and quality

Are Dehumidifiers Under $100 Worth it?

The idea that something as powerful as a dehumidifier should cost relatively little gives room for pause. However, these are small units built for small spaces, so they should be affordable.

Add on top of that technological advancements, and you can get yourself a fabulous product at a bargain.

Most of the units on our list use thermo-electric technology, meaning they don’t need a compressor, which is why they are also quiet.

Granted, they can’t compete with large models in terms of their water tank capacity or how quickly they can get rid of moisture from the air, but this all falls back to where you want to use the dehumidifier.

Therefore, if you are looking for a portable dehumidifier to place in a small room, then dehumidifiers under $100 are the way to go.

Our review made sure we only included items that are best sellers with literally thousands of positive reviews over several years. That way, you can be sure of their performance.

Advantages and Disadvantages of Buying a Small Dehumidifier

Dehumidifier under $100


  1. Portable

Weighing less than 10 pounds, mini dehumidifiers are easy to carry. This will prevent you from having to buy one unit for every room in your house.

They are also convenient if only particular regions in your home suffer from high humidity or mold, such as your bathroom, kitchen, or basement.

  1. Long-lasting

Despite their petite nature and limited capacities, these dehumidifiers last for a surprisingly long time. The E-333 is the leader in this segment, as its ten-year life span is the industry’s best.

Another verified user said he used his Seavon for five years before the plug wore out and had to replace it. Besides the plug, everything else is in good working condition.

  1. Travel-sized

If you suffer from allergies or asthma, chances are you would like to have a dehumidifier with you when you travel. Though most residential dehumidifiers can be used in an RV, these are also easy to carry on a flight.

Despite their small sizes, they can remove excess moisture quickly.

  1. Eco-friendly

Another important element to consider is the impact on the environment when buying any piece of machinery. For example, an electric mini dehumidifier uses thermoelectricity instead of a refrigerant, making it better for the environment.

  1. Save money

Besides the obvious reduction in purchase cost, you also get to save money on your utility bill. This is because these units use very little electricity compared to what you would get from a refrigerant dehumidifier or a desiccant dehumidifier.


  1. Small capacity

The first and most glaring drawback of these systems is that they are not as good at removing moisture from the air as larger models.

An electric mini dehumidifier has a smaller tank capacity than a compressor-based dehumidifier, but even then, it takes a lot longer to remove moisture.

If you are battling with high humidity or live in a big house with large rooms, you will need big dehumidifiers that can serve large rooms.

  1. Limited controls

Due to their small size, there isn’t much you can do in terms of control features. Most of them have just one button, if any at all. This means you can’t set the humidity level you want, change the fan speed or set a timer.

How to Choose a Dehumidifier Under 100 USD

When it comes to choosing dehumidifiers, there are just a few factors to consider. Unfortunately, although admittedly, the options in our review are so similar, some of them don’t make your decision any easier…oops!

But that also means it is hard to go wrong with any of these choices. So, nevertheless, here is how you can be sure you’ve made the right call.

  • Dehumidifier Capacity

When and how you want to use the dehumidifier are the most important questions you need to answer. This will guide you on which ones can work in the given space.

With every review, we have also included the coverage area and the capacity to help you decide. For example, the smallest unit is the E-333, which only covers 333 cubic feet, while the largest is the Honati, which has a 25 oz per day capacity of over 269 square feet.

  • Noise level (decibel level)

Given how noisy dehumidifiers can be, it is understandable why many buyers would sacrifice a larger capacity for a  quiet product.

That is not a distinguishing factor here because all of our review options operate at 39 dB. The only exception is again the E-333, which is entirely noiseless due to its silica insulation technology.

  • Weather performance

Almost every time you see a negative review for any of these products, it usually has to do with moisture removal, i.e., it doesn’t remove as much as advertised. The main reason for this is the temperatures in which they are using the unit.

Not surprisingly, the reviewers do not say what the temperature in their location is. However, most of the mini dehumidifiers you find work within the same temperature bracket.

Alrocket boasts an impressive range of 41°F-122°F, making it the best option for winter.

But depending on your climate and the home’s condition, you may need a whole-house humidifier and dehumidifier combo to keep a constant, comfortable environment in your house.

  • Drainage options

Manufacturers tout the portability of electric dehumidifiers as a marketing strategy, so it is not surprising they don’t come with a continuous drainage option.

What then differentiates them is their water tank’s size and how often it needs to be emptied. If you don’t want to clear the tank daily, but you want a considerable output, then the Honati Home Dehumidifier is what you need.

  • Control features

The more control features you have on a dehumidifier, the better. But with these mini versions, you only get one control button with a simple on and off function. So, you can’t set the humidity level, timer, or fan direction.

Alrocket has found a way to make the button mean more as you can use it to change the color of the light that shows in the water tank.

  • Warranty and customer service

Despite these units’ low price points, it doesn’t hurt to have a warranty to cover any faults in the system. If like me, you are money conscious, then the E-333 will appeal to you.

The five-year warranty is the best we’ve seen for any dehumidifier we have reviewed. Its ten-year life span is also a huge bonus. The two years offered by Seavon are also worth appreciating.

Now that you can comfortably decide on the best dehumidifier for your home, it is time to reveal ours.


Have you used any of the units above or any competitors? We would love to hear your feedback in the comments section below.

As for us, we are ready to reveal that the best dehumidifier under 100 dollars is the Eva-Dry. It is truly portable, noiseless, and is very dependable in the long run.

It may not remove as much moisture as the others, but its dependability is a huge plus! The Pro Breeze Electric Mini Dehumidifier is our runner-up.

It is pocket-friendly, can be used in decently sized rooms, and is a fabulous decorative addition to any room.
