If you are dealing with humid spaces in your home, adding a dehumidifier might be the best way to make the room more comfortable and avoid issues like mold and mildew. “Ideally a home would be kept between 40 to 60 percent relative humidity,” said David Ragsdale, Production Manager and Institute of Inspection Cleaning and Restoration Certification Instructor at SERVPRO. “If your home or business is consistently higher than this range a dehumidifier may be recommended.”
We researched dozens of humidifiers and tested a few in our homes for several weeks, evaluating ease of setup, effectiveness, design, and additional features.
TOSOT 20 Pint Dehumidifier
Very efficient performance
Numerous safety features
Relatively quiet operation
Large tank with carrying handle to reduce spills
Hose for continuous drain not included
We selected the TOSOT 20 Pint 1,500 Sq Ft Dehumidifier as our best overall pick because it works for a variety of spaces and can remove a whopping 2.5 gallons of water from the air each day. Plus, it has plenty of features that make it easy to set up and program, including a moisture setting between 35 and 80 percent. All you have to do is program the desired humidity level and the unit adjusts as needed, giving you all the benefits of a dehumidifier with the least hassle.
It has a large bucket to collect up to 1 gallon of water. When you need to empty it, just grab the carrying handle, which we found to be a key feature that sets this dehumidifier apart from others for its ease of use and ability to prevent spills and messes. You can also set it up for continuous draining with a 3/4-inch drainage hose, although you’ll have to purchase the hose separately.
While testing, we also appreciated this dehumidifier’s energy and safety features. It is Energy Star Certified, which means that it doesn’t draw a lot of power and won’t increase your electric bill drastically, even if you run it continuously. It is made of fireproof materials and has a sensor that sounds an alarm if the bucket is getting close to full. And, it has a washable filter to help make sure that the unit doesn’t get clogged with contaminants. We also noted that this humidifier is relatively quiet, which is helpful if you need to use it in a bedroom (in fact, it didn’t wake us up when it turned on).

Eva-Dry EDV-1100 Electric Petite Dehumidifier
Small and portable
Easy to store
Doesn’t collect a lot of water
Running a dehumidifier is one way to prevent mold in the bathroom, so we tested this compact, lightweight unit in a bathroom and found it to be an effective, yet affordable option. It has a tinted tank so that you can see the water level inside, which is helpful since it is a smaller, 16-ounce-capacity unit and can fill quickly. However, the smaller size does make it easy to keep on a shelf or other out-of-the-way location compared to some of the larger dehumidifiers on our list. We also found that it was easy to remove the tank, as well as easy to clean.
Keep in mind that this budget-friendly unit doesn’t have a lot of special features and can’t be adjusted or programmed. It simply has an on/off switch. When the tank is full, an LED indicator light turns on so that you know it is time to empty the dehumidifier. You can’t set it up for continuous use, so this is best for occasional use when you need to adjust the humidity level in a smaller space.

Pro Breeze 0.45-Pint Dehumidifier with Bucket and Auto Shut Off
Full tank indicator light
Another small and affordable dehumidifier, the Pro Breeze 0.45-Pint Dehumidifier with Bucket and Auto Shut Off is only 8.66 x 6.1 x 5.1 inches. It weighs 2.29 pounds, making it easy to lift and move from room to room as needed. You can also put it on a boat or RV for travel—they're perfect in tiny homes. Because it doesn’t have a pump or compressor, it is also quiet enough to keep in a bedroom without disturbing your sleep.
This compact unit is not programmable and doesn’t have any special features or settings, but it is simple to use. You just switch it on and the dehumidifier runs at one speed, removing up to 9 ounces of moisture from the air per day. It does have two indicator lights, one to tell you that the unit is on and the other to tell you that the tank is full. To empty the tank, you’ll need to pull it out from the front of the unit and empty it manually.

Best for Basements
hOmeLabs 4,500 Sq. Ft Energy Star Dehumidifier
Can set desired humidity level
Turbo fan speed
Continuous drain hose not included
Not easy to empty or move
The hOmeLabs 4,500 Sq. Ft Energy Star Dehumidifier has a large capacity and is perfect for basements and other spaces that need extra power or are routinely damp, which can attract pests that thrive in moist environments, particularly in new constructions. It covers up to 4,500 square feet and can work for finished or unfinished basements. You can run it as an isolated system or set it up for continuous use. During testing, we found this humidifier to be really user-friendly, with very detailed instructions. The controls are also easy to use: Just set the ideal humidity level and let it automatically adjust as needed. There is even a turbo fan option if you want the fastest response.
The default setting is continuous drainage, which is the best option if you expect it to run often. The tank is large at 1.6 gallons. However, you will still need to empty it as it fills so we think setting it up as a continuous drain system is ideal. In fact, we found it hard to remove and drain the bucket when completely full. Also, it’s worth noting that we found it very hard to move during testing, especially down the stairs, so this is not a great portable option. It has a ready-to-use connection but you will need to get a separate drainage hose (a standard garden hose is recommended).

Best for Bedrooms
Frigidaire 35 Pint High Efficiency Dehumidifier
Collection tank has a splash guard
Good capacity for its size
Not great for very large bedrooms
We recommend the Frigidaire 35 Pint Dehumidifier for bedrooms because it is versatile, easy to empty, and relatively quiet. You can set this dehumidifier up for self-contained use or continuous use. Plus, we like that the bucket is at the front of the unit, which helps when it comes time to empty it. There is a carrying handle on the top and a helpful splash guard to keep the collected water from spilling over onto your carpet or flooring. It also has a washable filter so that dust is removed from the air as well as moisture. Plus, the noise level is one of the lowest on our list, a key feature for use in your bedroom.
There are four sizes of dehumidifiers from Frigidaire with the same helpful features. The 35-ounce capacity works well for a medium-sized space like a bedroom. It is a good balance of capacity and size since you likely don’t want an extra large dehumidifier that will take up a lot of space. It measures 15.96 x 12.19 x 24.25 inches and has a relatively unobtrusive style that won't disrupt your bedroom's relaxing vibes.

Best for Bathrooms
TABYIK 35 OZ Dehumidifier
Can hold a lot of water for its size
Not good for continuous use
Compact in size, the TABYIK 35 OZ Dehumidifier is perfect for bathrooms since it can take care of periodic humidity without taking up a lot of space or requiring a complicated setup. It works in spaces up to 280 square feet, which can account for even a larger bathroom or adjacent closet. A fun and practical feature, the clear tank on the bottom can also function as a night light with adjustable colors—this is helpful if you do need to use the bathroom in the middle of the night. You can also turn the light off separately if you prefer a darker space, and only want to use the dehumidifier.
If you need to run your dehumidifier continuously, this isn’t a good option since it can only be set up to collect water in the self-contained bucket. This unit can collect up to 16 ounces per day but does need to be manually emptied. Fortunately, the small bucket size and hand holds make that process easy, especially in a bathroom where the sink is nearby.

LG PuriCare 50-Pint Dehumidifier with Drain Pump and Wi-Fi
Works with an app or smart home voice controls
Can get alerts to your phone
Several safety features
Hose for continuous drain not included
If you want to control your dehumidifier from your smartphone or smart home hub, this is the best unit to get. It is compatible with smartphones via an app, as well as Alexa and Google Home via voice controls. You can also get alerts when the bucket is getting full, make adjustments to the desired humidity level, and start or stop the dehumidifier remotely.
You can use this with the large 1.7-gallon capacity bucket or set it up for continuous drain operation. It has a built-in pump so that the water gets pumped to a nearby sink, although you will need to get a separate drainage hose. We also like that it has multiple safety features, including a full bucket alarm, and airflow blockage alarm, and is made of non-flammable and heat-resistant materials. On top of all these features, it also has a sleek black case and design.

Best with Drain Hose
GE 22 pt. Dehumidifier with Smart Dry
3 fan speeds
Auto adjusts fan as needed
Sounds alert for full tank
Continuous use requires access to drain or sink
The GE 22 pt. Dehumidifier with Smart Dry for Bedroom, Basement or Damp Rooms features a humidistat that automatically adjusts it to create the ideal environment based on your settings. It features three fan settings and turns on and off when needed to achieve the desired humidity level. Plus, the dehumidifier measures the humidity level in the air and cycles the fan between the three speeds without you having to make any adjustments. It also automatically shuts off when the tank is full and sounds an audible alert.
You can set it up for continuous drainage using the included hose connection, however, keep in mind that you will need access to a slop sink or drain. Overall, this is a good dehumidifier to use for routine use in humid environments, such as bathrooms and bedrooms. You can use it in the basement but you may need to empty the tank often if you are experiencing particularly high moisture levels.

Midea 4,500 Sq. Ft. Energy Star Certified Dehumidifier With Reusable Air Filter
Multiple modes of operation
Wheels for easy portability
Heavy and bulky
For a quiet dehumidifier that also performs great and has a large enough capacity to work well in a basement or larger space, we recommend the Midea 4,500-square-foot dehumidifier. It has multiple modes, including a collection tank, continuous drain, timer mode, and turbo mode for really humid spaces. You can choose your mode of operation using the intuitive buttons at the top of the unit.
This dehumidifier generates less noise than a standard household refrigerator. It operates at around 49 dBA, although that increases up to 54 dBA when you use it with one of the higher settings. If you do need to move it, the unit comes with 360-degree rotating wheels, a key feature that makes it easier to move, even though it is over 40 pounds.

Plus, it has all of the safety features that you might need around your home. For a more budget-friendly dehumidifier, we like the Eva-dry Edv-1100 Electric Petite Dehumidifier. Although it has a smaller capacity, we appreciate its compact size and full tank indicator light that alerts you when it needs to be emptied.
What to Look for in a Dehumidifier
Pints per Day
The amount of liquid that a dehumidifier can remove from the air within a 24-hour period is typically measured in pints per day—though occasionally you’ll also see it labeled as gallons per day. Typically, the number of pints per day will be closely related to how big of a space the unit can dehumidify.
Small-capacity dehumidifiers are those that remove about 20 pints per day or less. These mini dehumidifiers are best suited for bedrooms or bathrooms. Mid-size dehumidifiers will usually be able to remove 30 to 50 pints per day of moisture from the air, making them much more versatile for use in your home. The most robust portable dehumidifiers can suck 70 pints or more of moisture per day from the air.
If you are getting a dehumidifier to keep in one room that gets humid often, such as a basement, a larger unit might be worth the bulk to get increased capacity. Smaller spaces can generally have a smaller dehumidifier. If you need to move the dehumidifier around, look for one that is small and light enough to carry or one with wheels.
Water Tank Capacity
The capacity of the water tank in your dehumidifier will dictate how often you need to empty the unit. If the tank becomes full, a float sensor inside the tank will cause the unit to shut off. It’s important to know that dehumidifiers with an increased ability to remove more pints per day of moisture from the air don’t have tank sizes to match since that would make the size of the unit huge! Instead, most standard-size dehumidifiers have tanks that only hold about 1 gallon of water (some hold a little more and some hold less). As a result, if you want the unit to keep working at maximum efficiency, you’ll either need to empty the tank multiple times per day or set the unit up to continuously drain.
Some dehumidifiers are equipped with a digital display and keypad that makes operating the machine easier. Instead of turning knobs or simply powering the unit on, the electronic controls will let you set specific programs or tell the unit to stop running once a target level of humidity is reached (called an auto-humidistat). Not only will it be easier to operate, but a model equipped with electronic controls can also help lower your electric bill (along with other energy-savers like ceiling fans and dimmer switches).
The type and length of warranty coverage available on a dehumidifier often vary. Like many small home appliances, basic dehumidifiers are usually covered by a one-year warranty against defects in materials or workmanship. This warranty typically covers a replacement unit if your dehumidifier fails within the first year. For some manufacturers, this is where warranty coverage ends. Others, though, offer a longer limited warranty window in which parts like the compressor and coils of a refrigerant dehumidifier are covered. Read the details of any warranty policy on a dehumidifier you plan to purchase to understand what may be covered and what isn’t.
Drainage and Pumps
If you don’t want to frequently empty the water tank of your dehumidifier, you can look for a model that includes a built-in drain. The most simple drainage system is powered by gravity, but some units are equipped with a more powerful drainage pump. If you plan to use your dehumidifier in a basement with a nearby floor drain, a gravity drain may be sufficient. Just note that you’ll usually need to buy your own drainage hose to use with the dehumidifier. Make sure that the unit isn’t located too far from the drain and that there is at least a gentle slope to ensure that gravity can do its job to move the wastewater from the tank to the drain.
If you want to power the water from the tank to just about anywhere, then a dehumidifier with a drainage pump is a better option. These dehumidifiers are equipped with a pump and included hose that can direct water up and out of the tank to a utility or laundry room sink or any other drainage location within the reach of the hose.
A third option to consider is buying an aftermarket dehumidifier pump that can connect to your unit and give you additional options for draining the collected moisture.
Energy Star Ratings
If you know that you’ll need to run your dehumidifier often, it’s best to find one that is Energy Star Certified. Not only is this better for your wallet by saving you money on electricity costs, but it can also be beneficial to your home’s electrical system since it does not put as much of a strain on it. An energy-efficient dehumidifier is also a good eco-friendly choice.
When do I need to use a dehumidifier?
While there is some level of personal preference, the optimal humidity level in most rooms and homes is between 30 and 50 percent. Most dehumidifiers can be programmed to set the humidity level between 30 and 80 percent.
If your home is very humid, you might experience problems with mold or mildew growth as well as general discomfort. If you see any signs of mold or mildew, especially in spaces like basements or bathrooms, it is a good idea to set up a dehumidifier as well as treat the existing problem.
What size dehumidifier do I need?
Look for a dehumidifier that is capable of handling the square footage of your room. It is best to get one that can work for larger spaces than you need to ensure that it can be effective. You should also consider the typical humidity level in the room and how much it may need to run. Most dehumidifiers have recommended space sizes and humidity levels.
“A dehumidifier’s physical size is really irrelevant,” says David Ragsdale, Production Manager and Institute of Inspection Cleaning and Restoration Certification Instructor SERVPRO. “What is important is the amount of water the dehumidifier will remove from the air in a 24-hour period. This is measured in either pints or liters per day.”
Are dehumidifiers hard to clean?
Most dehumidifiers can be cleaned with mild soap and water in the collection tank. The exterior can be wiped down.
Where should you put a dehumidifier?
Bathrooms and basements are the most common places to put dehumidifiers, since they are the rooms that typically get the most humidity and moisture. You can put a dehumidifier in any room, however, and set it for your desired humidity level.
