We also picked a variety of sizes and coverage areas to ensure you have the perfect one for a small closet or a large basement, depending on your needs. We even picked a dehumidifier with a continuous drain option that eliminates the need for frequent tank emptying, even when the machine is running constantly. If you’re looking for the best dehumidifier under $100, check out our detailed reviews and buying guide below.
If you’re looking for the best electric dehumidifier under $100, the Pure Enrichment PureDry Mini Dehumidifier may be the right model for you. This model is sleek, with a transparent water tank at the back and a slim water level window at the front, so you never have to guess how much water has been collected.

What we liked: The Pure Enrichment PureDry Mini Dehumidifier has a slim, sleek design and a compact size, so you can fit it almost anywhere. It also has great features, like the single switch for easy use and the transparent water tank for consistent water monitoring.
What could be better: The on/off switch and the indicator lights are all on the back of the unit, which makes them a bit trickier to access than other machine designs.
Rather than buying a dehumidifier and an air purifier separately, you can choose one machine that does both jobs, like the Tenergy Sorbi Air Dehumidifier. This unit is a portable combo model that cleans your air as it removes the excess moisture.
For air filtration, this model includes a True HEPA filter that captures up to 99.97% of airborne particles, including pollen, dust, pet dander, and much more. The air that is sent through the unit comes out fresh and clean, with fewer allergens to eliminate any allergic reactions.
To help decrease mold and mildew from overly humid air in your home, this model removes up to 25.4 ounces of moisture from the air each day. The tank holds up to 33.9 ounces, so you only need to empty it every other day or so, depending on the humidity level in your home.
Despite its dual functions, this dehumidifier for mold under $100 is quiet, running at about 35 to 42 decibels, so it can even be used in your bedroom. It is also small and portable, plus is ETL and CARB certified, so you know it is a high-quality, safe machine for your home.
What we liked: We liked that this unit is very quiet, easy to clean, and is ETL and CARB certified. It also includes a True HEPA filter to clean the air of allergens while the dehumidifier removes the moisture.
What could be better: There is only 1 HEPA filter included, so you do need to buy replacements every 5-6 months.
The Ivation Thin and Compact Dehumidifier is a thin model that can fit on a desk, shelf, or tucked in a corner out of the way. It has a small coverage area of 30 square feet, so is a great option for closets, small bathrooms, or crawl spaces that are dealing with some excess moisture.
This model uses Thermoelectric Module and Heatsink Technology, which works to cool, condense, and dissipate the air, removing up to 13.5 ounces of water each day for a more comfortable room. As well as the quick dehumidification, this model also includes an automatic defrost that allows you to use it in colder temperatures without damaging the machine. A honeycomb structure inside the air intake helps purify the air, clearing out odors for a cleaner-smelling room.
There is a simple one-touch operation to turn the unit on and off, as well as indicator lights that tell you when the machine is running, when the defrost is on, and when the tank is full. A transparent water level window shows you how high the water is at all times.
What we liked: The best features this model has to offer are the slim design, the clear tank window, the auto-defrost function, and the long power cord that gives you more placement options without requiring an extension cord.
What could be better: The water tank is a bit small, so will need more frequent emptying, though the tank size does help keep the unit more compact.
Not everyone needs a huge dehumidifier to reduce the moisture issues in their home. For these people, the best dehumidifier for under $100 may be the Pro Breeze Electric Mini Dehumidifier. This model has a coverage area of 150 square feet, so it is perfect for small bathrooms, bedrooms, and kitchens. It is also lightweight, so you can move it wherever you need it at any time.

Another great feature this model has to offer is the auto-shutoff that turns the unit off when the tank is full. There is also an LED indicator light that lights up to remind you to empty the tank.
What we liked: We liked that this unit has a compact size for small rooms, is whisper-quiet, and has a decent price that fits into any budget. There is also an auto-shutoff with an LED indicator when the tank is full.
What could be better: This is a small unit, so the water canister is also quite small, requiring frequent emptying on very humid days.
The InvisiPure Hydrowave Dehumidifier is the best dehumidifier for a basement under 100 dollars, plus it works great in many other rooms as well. Not only does it have a decent-sized water tank that can hold up to 64 ounces of water when full, but it also has a continuous drainage option that allows you to attach a 3/8-inch hose for constant drainage as the unit runs.

What we liked: We liked that this dehumidifier has a large water tank, plus has the option of adding a hose for continuous drainage. It also features a washable filter and an auto-shutoff to eliminate overflowing when the tank is full.
What could be better: The cord is a bit short, so it needs to be close to an outlet. There is also a light on the front, which is a bit bright for some people, especially at night.
Things to Consider
Those on a budget may not be able to afford a huge, high-end dehumidifier to take care of these issues, but a smaller model that costs less than $100 is a great alternative. Though cheap, these little dehumidifiers work well in small spaces, taking up very little room while still doing a fantastic job of removing the excess moisture from your home. If you’re unsure which one is right for you, check out the sections below for more information.
Features to consider when choosing a dehumidifier under $100
When choosing the best dehumidifier for under $100, there are a few features you may want to consider. This will ensure you’re getting the right model for the space you have available and the moisture issues you’re dealing with.
The coverage area listed for the dehumidifier you buy is one of the most important features since this tells you the largest area the model will work well in. The smaller the coverage area, the smaller the area your dehumidifier can be used in.
For instance, the Ivation Thin and Compact Dehumidifier has a coverage area of 30 square feet, so it can be used in crawl spaces, powder rooms, closets, or other small areas that are this size or smaller. If you tried to use this model in a room that exceeds this area, it likely won’t be able to keep up, removing very little moisture out of the air since it can’t circulate the air efficiently.
For large rooms, you need a unit that can handle the space. Of course, you won’t be able to get a whole-home dehumidifier for under $100, but at this price, but you can get few small ones and place them wherever you need them the most in your home.
The capacity of a dehumidifier tells you how much water the tank will hold before the unit shuts off or overflows. The more water it holds, the less often you need to empty it on a particularly humid day. Some of these models only hold small amounts of water, like the Pro Breeze Electric Mini Dehumidifier, which has a capacity of 16 ounces. This means that the tank isn’t very big, so on a humid day, you may be emptying it once a day or more, depending on how long you have it running.
A larger tank, like the 64-ounce reservoir on the InvisiPure Hydrowave Dehumidifier, holds more water, so you may only need to empty it every few days. Of course, the more water there is in the tank, the heavier it will be to carry to a sink or drain to empty it. Though it takes less time, it may be a more difficult task, so keep this in mind when choosing a new dehumidifier model.
Another feature to look into when choosing a dehumidifier for under $100 is the performance. This tells you how much moisture the unit is pulling from the air over an entire day. This can vary depending on a unit, so don’t assume that one with a higher coverage area or a larger tank will work faster than a smaller, lower coverage model.
Most of the small capacity models that cost $100 or less have lower dehumidification performance than the more expensive, high-end models. The ones in our reviews range from about 10 ounces per day to almost 30 ounces per day. As well as looking into the features we’ve described above, consider the humidity in the area you live in and how efficient you want your model to be. Higher humidity may need better performance to keep moisture issues at bay.
Dimensions and weight
The dimensions of the unit tell you how much space the dehumidifier will take up in your home. Most of the cheaper models on the market are compact, but there are some differences to consider. You can choose a tower dehumidifier under $100, like the Ivation Thin and Compact Dehumidifier, which are tall and slim, so you can squeeze them onto a shelf or desk without using up too much space. There are also square-shaped or rounded models that are a little wider but are also short, so they can fit onto a nightstand or even in a corner of a bedroom or bathroom. Consider where you’d like to place your dehumidifier and buy the model that fits best with the other features you want.
You should also consider the weight of your new dehumidifier, especially if you plan on moving the little model from room to room. Luckily, all of the models in our reviews are quite light at less than 10 pounds each, so you won’t strain yourself when you shift their position now and then.
Though not a common feature on these types of dehumidifiers, a few of them do have a built-in handle on the unit that makes it easy to carry it with you wherever you need it. The InvisiPure Hydrowave Dehumidifier is one of these units, with a carry handle located at the back of the unit, built right into the plastic. This gives you the perfect handhold when you are carrying your dehumidifier to a new room or from your RV to your house after a camping trip. A built-in handle makes a unit like this much more portable and easier to move when needed.
The features described above are the main ones to focus on when choosing a new dehumidifier under $100. Of course, there are some extra features you may want to consider since these will make the model you purchase much more convenient to have in your home.
One thing to look at is the controls. These should be easy to use, even if it’s your first time setting up a dehumidifier. All of the models in our reviews have a single button or switch to turn them on and off.
An auto-shutoff is also something to look for. This feature turns off the dehumidifier when the water tank reaches a certain level. This prevents the tank from overflowing, so you won’t have a mess to clean up. An indicator light is often included with the auto-shutoff, turning on or changing colors to tell you that the tank needs to be emptied. Many models also include transparent tanks or a tank window to allow you to monitor the tank level at all times.
The dehumidifier design is another feature to consider. Some of the models in our reviews have a sleek, modern look, while others are more utilitarian. They also come in varying shapes and sizes, with tanks and controls located at the front or the back. Choose the design you like best that will work well in your home.
This depends on the amount of moisture you’re dealing with. It is a good idea to leave your dehumidifier running at all times when trying to eliminate moisture from a leak or plumbing issue or in damp or humid weather to reduce the moisture levels in your home. In drier climates or for bathrooms with low ventilation, you can turn it on when you need it and then off again instead of running it continuously.
To clean the water tank on a dehumidifier, you first need to turn off the unit and empty any water it has collected. Then fill the tank a quarter full with warm water and a few drops of dish soap. Scrub it with a sponge, getting into all the corners. Empty the tank again, then spray it with pure vinegar. Leave it for about 10 minutes, then wipe it clean with a damp cloth. Let it dry, and then replace it in the dehumidifier.
The continuous drain option allows you to attach a hose to the unit, which allows the dehumidifier to drain the water instead of collecting it in the tank. This is a great option for those who plan to use the dehumidifier constantly since you don’t have to empty the tank every day or two to keep it running. You do need a drain near the dehumidifier for the hose to drain into, like a floor drain in a basement or a sink.
A dehumidifier under $100 can help you eliminate any moisture issues in your home without breaking your budget. Though all 5 of the units in our reviews are great options, we have a few favorites.
