How to pick the best cheapest dehumidifier

Anyone who lives in an area with high humidity will tell you that a moisture absorbing dehumidifier can be a lifesaver around the house and for your personal belongings.

A few years ago, I received a job offer that was located in the Pacific Northwest. It was a great opportunity for my career, so my family packed up their stuff and made the cross-country move.

Once we settled in, we quickly noticed how humid and muggy it felt. On some days, it was unbearable to be outdoors. On others, certain parts of the home were even damp and uncomfortably sticky.

After chatting with my new neighbors, I learned that the relative humidity averaged between 70 to 80 percent almost year round. That was quite a shocker, to say the least!

Thankfully, the house we bought had a very good ventilation system except a few rooms did have trouble spots. This included the hall bathroom and the master bedroom walk-in closet.

I knew from experience that high humidity indoors can cause mold and mildew growth, wood rot, and rust to form. It also causes respiratory issues in people who have allergies or asthma.

When my wife complained that the clothes in the closet felt damp, and I noticed mold growing in the bathroom, I knew something had to be done, fast.

After doing some research, I discovered that a small dehumidifier could help with our humidity problems and I didn’t have to spend a lot of money on it.

This was great news!

Now, if my house didn’t already have good ventilation, I would’ve been forced to spend $300 or more for a larger dehumidifier to help fight the humidity. Thank goodness that wasn’t the case.

Since I only had two small areas of the home that needed fixing, I could buy the cheapest dehumidifier available and it would take care of the high humidity issues.

So, that’s what I did, and it worked. However, it wasn’t without some serious trial and error. Not every moisture absorbing dehumidifier performed as well as I thought it would.

So, how do you find the best cheap dehumidifier available without taking time to test them all?

That’s where I can help!

As your trusty companion, I’ve researched and compared more than 13 of the best small dehumidifier models out there and outlined my findings in this short buying guide.

Most of the products listed on this page are perfect for any part of your home, including the basement, closets, bathrooms, garage, gun safes and more. They also work great in RVs and boats too!

So, no matter where you’re having trouble with high humidity, you can rest assured the best mini dehumidifier for your needs is on this list.

Trusty Joe with Checklist

Features to look for in the best cheap dehumidifier

Before we get to the reviews, let’s go over the most important parts of a portable dehumidifier. 

There are some key features you’ll want to look for when shopping for a dehumidifying device. Paying attention to these things can make a big difference in how happy you are or not with the product.

water capacity

Water capacity

Dehumidifiers are designed to do one thing, and that’s to suck moisture out of the air. But where does all of that water vapor go? Into a water tank.

The total water capacity determines how much moisture can be collected before you have to empty the tank.

If you’re going to be around your dehumidifier a lot, you may not mind a smaller tank because you’ll be able to check on it regularly. But if you tend to get busy like I do, a larger tank is well worth the investment because you won’t have to keep an eye on it as much.

Smaller dehumidifiers can remove between 16 to 100 ounces of water from the air before they have to be dumped out. Depending on the size of the tank you get, and how humid the room is, could mean the difference between emptying it every 2 days versus every 5 days, or more.


Daily moisture extraction

Another good thing to know about your new dehumidifier is how much moisture it can pull from the air on a daily basis.

If you live in an area with high humidity like I do, the more moisture it can extract from the air, the fewer problems you’ll have indoors.

Some lower priced air dehumidifiers are not very efficient and are limited in the amount moisture they can extract each day. So you’ll want to pay close attention to this number when shopping around.

The top products I review below pull anywhere from 10 to 68 ounces of water vapor from the air in a 24 hour period. This range covers most people’s needs for a compact dehumidifier.


Room coverage

Here’s something you definitely don’t want to run into – buying a brand new electric dehumidifier only to find out that it’s not powerful enough to get the job done.

To avoid this headache, you need to make sure that your device can cover the entire area that you’re going to place it in.

In my case, I was lucky and only had to lower the humidity in two very small rooms of the house (hall bathroom and a closet).

One thing to keep in mind is that dehumidifiers use the term “cubic feet” to indicate how much space they can handle. This measurement is simply the width x length x height of an area or room.

Smaller portable dehumidifiers cover anywhere from 300 to 2,200 cubic feet.

To help you understand what this means in a real-life setting, consider the following:

  • 300 cubic feet is about 100 square feet (or a 10′ x 10′ room)
  • 1,600 cubic feet is about 200 square feet (or a 10′ x 20′ room)
  • 2,200 cubic feet is about 275 square feet (or a 10′ x 27′ room)

Your goal should be to get a dehumidifier that can at least cover the size of the location you need it in. If you don’t, you’ll just be wasting your money.

To make this easy for you, I’ve converted cubic feet to square feet for all of the products I recommend below. Square footage is much easier to calculate. Just multiply the width x length (in feet) of a space to get your answer.


Automatic shut off

One thing you’ll love most about modern air dehumidifiers is how quiet they are. While this makes them pleasant to be around, it also means they’re easy to forget about.

I mention this because it could become a potential problem if your electric dehumidifier doesn’t automatically shut off when the water tank reaches its fullest point. If the tank runs over you’ll have a big mess to clean up.

For that reason, it’s always best to choose a product that has an auto shut off function. You’ll find it to be a lifesaver during those times when you’re not at home or someone forgets to check on it.

Every one of the top rated portable dehumidifiers listed below includes this handy feature.



One of the things that I really like about small and mini dehumidifiers is that you can put them almost anywhere and they stay out of the way.

This was an important concern of mine when I used a dehumidifier in my closet and bathroom because I didn’t want anyone accidentally tripping over it or bumping into it.

When you’re comparing air dehumidifiers, you’ll want to find a good balance between the overall dimensions so it fits where you need it to. This is especially important if you’re going to use it in smaller locations in the house like a gun safe, or inside an RV, camper or boat.

Review Top Choice

Pro Breeze Small Dehumidifier

Review Best Cheap Dehumidifier Pro Breeze Small Dehumidifier
If you’re looking for the best cheap dehumidifier that covers a good amount of space, this your top choice.

The tech specs say that it handles up to 1,200 cubic feet, which in layman’s terms means it can cover 150 square feet (or a 10′ x 15′ room).

For the price, you’re getting an average size water tank with a capacity of 16 ounces. It also removes up to 9 ounces of moisture from the air each day. This means if there’s a lot of water vapor in the air, and you’re running it 24/7, you’ll have to empty the water tank every two days.

The good news is that this product has an automatic shut off feature, so the collection tank won’t overflow. An LED light also alerts you to when it’s time to empty the tank, so you’re covered on all fronts!

This is the same moisture absorbing dehumidifier I used in my home back in the Pacific Northwest. It’s a handy little fella to have around the house and is great for any room (or closet) that needs dehumidifying!


Review Second Best

Ivation IVADM35 Small Dehumidifier

Review Ivation IVADM35 Mini Dehumidifier
The second best mini dehumidifier you can buy for your home is this product right here.

At first glance, it almost looks identical to my top pick. Just the front grill is different.

However, there are a few more subtle differences that are worth pointing out.

For starters, it covers 2,200 cubic feet (1,000 more than the Pro Breeze). This roughly equals 275 square feet or a 18′ x 15′ room.

The water tank holds 68 ounces of water (3x more than the Pro Breeze) and collects 20 ounces of moisture from the air each day. That means you can go several days without having to empty it.

Like the Pro Breeze, you also get an auto shut off feature and full tank indicator light to prevent water overflowing.

So, which is the better dehumidifier for you to get? Let the room size you’re using it in be the deciding factor.


Review Third Pick

Eva-Dry E-333 Mini Dehumidifier

Best Mini Dehumidifier by Eva-Dry E-333
Are you looking for a top rated mini dehumidifier that’s small, lightweight and doesn’t require much maintenance?

How about a product that doesn’t use batteries or even needs to be plugged in order to work?

If that sounds like a dream come true, I assure you that it’s real, and it comes packaged in this product right here.

There’s no other cheap mini dehumidifier quite like this one. Instead of using a tank to collect water, it has crystallized silica gel that absorbs moisture and never leaks. After 20-30 days of collecting 8 to 10 ounces of water vapor, all you have to do is recharge it so it can continue dehumidifying the space. Plus, it lasts up to 10 years!

This product is perfect for closets and enclosed spaces. It’s especially great for protecting your clothes and valuables from mold, mildew and moisture rot. If you’re looking for the best moisture absorbing dehumidifier or small spaces, this compact design is exactly what you’ll need!

For a tiny portable dehumidifier that can cover 333 cubic feet or a 10′ x 10′ area, it’s tough to beat!


Review Fourth Pick

Hysure Compact Dehumidifier

Review Hysure Compact Air Dehumidifier
Perhaps you like the efficiency of my first cheap electric dehumidifier recommendation but wanted something a bit more modern looking.

If so, this may be the perfect device for you.

It covers an equal amount of space as the Pro Breeze model at 150 square feet, or a 10′ x 15′ space, which is perfect for a small basement room, garage, attic, RV or even a boat.

The water tank on this Hysure model is much bigger though (24 ounces) but extracts about the same amount of moisture each day (10 ounces). That means you’ll won’t have to empty it as often as the Pro Breeze model.

A full tank light indicator and automatic shut off feature are also included for peace for total peace of mind. And it looks pretty sharp, don’t you think?


Review Fifth Pick

Kolamama Portable Dehumidifier

Review Kolamama Dehumidifier
My final recommendation for the cheapest dehumidifier you can buy that covers a very large space is this product right here.

I’ll warn you that it does have the highest price tag of any other product on the page but there’s a very good reason for it.

This device extracts about double the amount of moisture each day than my other top picks. 68 ounces to be exact. And it has a huge 100-ounce capacity water tank. If you live in an extremely humid area and want something that works fast, and for long periods of time without having to mess with it, this is the dehumidifier you’ll want to get.

Total area coverage is strong too, at 323 square feet, making it the top rated choice for bedrooms, basements, offices, garages, storage sheds, living rooms, and other large areas.

If you want the best of the best this dehumidifier is it!

Additional Information about Dehumidifiers

How Dehumidifiers Work

When humidity levels are high in your home or anywhere, the air feels like it’s very heavy. This can make it difficult to breathe for people with certain respiratory conditions like COPD or asthma. It’s also one of the main reasons dehumidifiers exist.

A dehumidifier is an appliance that pulls the humid air in, removes the excess moisture, and redistributes it into the home. It has a fan, cooling unit or coils, a reheater, and a reservoir bucket to catch the excess water. Once you turn your dehumidifier on, the fan starts sucking the surrounding air into the unit.

The air gets circulated in the inside of the dehumidifier, and it gets passed through the internal cooling coils. These coils lower the air’s temperature, and this cooler temperature allows the coils to pull the excess moisture from the air. The air is then quickly reheated. This reheated air is pushed back out into the room without the excess moisture and therefore reduces the relative humidity levels. (source:

Cheaper dehumidifiers use a tray or bucket to collect the moisture that has been removed from the air. More expensive dehumidifiers also use that method to remove moisture but some may also come with a hose that allows you to drain the water into a floor drain or pump.

Indirect Health Effects of Humidity

Unfortunately, there are several indirect health effects that come with having high indoor humidity levels. Learning about these possible health effects can help you to understand why people use dehumidifiers, and why they’re vital in very humid environments.

You’ve likely noticed that the hot, humid, air feels heavy and makes it more difficult to catch your breath. It’s uncomfortable because this type of air actually interferes with your body’s natural ability to cool down and regulate your body temperature. Having too much relative humidity indoors makes it difficult to cool down.

Also, viruses and bacteria thrive better in humid environments. These things are also able to stay in the air instead of settling on surfaces for much longer periods. This means that your risks of breathing them in and getting sick or getting an infection are much higher in humid environments (source:

Mold, fungi, and allergens also run rampant in higher humidity. In fact, mold and fungi prefer moist and humid environments to grow. They can grow anywhere in your home, and this includes your carpets, furniture, air vents, ducts, bathrooms, tiles, walls, and closets.

The ideal relative humidity for indoors is 30 to 50%. Any higher and you’ll likely experience the issues outlined above. A small budget dehumidifier is an excellent way to reduce the humidity in select areas of your home so that you can maintain proper moisture levels.

Benefits of Owning a Cheap Dehumidifier

The main benefit of owning a dehumidifier is that it lowers your home’s indoor humidity levels. Once these go down, the allergens, mold, and fungi in your home should start to rapidly decrease because they won’t have an ideal environment to thrive.

They can also get rid of that musty smell that seems to cling to everything in your home when higher than normal moisture levels exist. These unpleasant smells are usually caused by mold and mildew growth, so reducing the humidity can get rid of the mold and mildew. This will also improve your home’s air quality and will make your home more comfortable to live in.

You might also notice a decrease in skin irritation and respiratory tract irritation if you experience these conditions. This is especially noticeable if you have respiratory issues like asthma, chronic bronchitis, or COPD.

Additionally, if you’ve ever noticed that your clothes feel damp inside your closet then an inexpensive dehumidifier may be just the thing you need. High humidity inside a bedroom can leave your clothes feeling this way and a dehumidifier will help them feel drier (and normal).

Finally, running a dehumidifier can help use your air conditioner more efficiently. Air conditioners reduce humidity in order to cool down a home. If the air inside your house has less moisture in it from using a dehumidifier then your air conditioner doesn’t have to run as hard or often to make the temperatures pleasant. In turn, you can see your overall energy costs reduced, and this can save you money by investing in a cheap dehumidifier.
