Moisture, mold and mildew can cause serious issues in a home, but the best dehumidifiers can make all the difference. A good dehumidifier removes humidity and condensation, which eliminates mold and musty odors.
However, it can be challenging to know the right one to buy for your home. These appliances are sold with a lot of jargon, and they can be pretty expensive.
The quick list
The Honeywell 50 Pint is an hassle-free dehumidifier for drying out any space. It's fast, quiet, and easy to use.
This compact dehumidifier is a great option if money and space are tight. Operated by an app, you can monitor it from your phone, view humidity levels and receive alerts when the bucket is full.
If you have flooding issues, you need this dehumidifier. Dan's tests found that it excels at reducing high humidity, even in large rooms. The only downside is that it's very loud.

Best overall
This Honeywell 50 pint dehumidifier more than stood up to Dan's tests. It was impressively effective in his basement bathroom. Multiple tests found that that it takes less than an hour to reduce levels of humidity from 90% down to 35%. Dan found that it was equally efficient for mid-sized spaces, such as the living room, kitchen and laundry room, and it's rated to handle rooms of up to 4,000 square feet.
On top of that, Dan was impressed by its quiet operation. It averaged 56dB, which is better than most, and you won't notice it running in a quiet room. The simple white design is inobtrusive, too, so it won't look out of place.
The power cable is a little short, and don't be fooled by the marketing; while it can handle 50 pints a day, the onboard water capacity is just 14 pints, so you'll be emptying that tank frequently for the full 50 pints of removal per day.
However, you can use the included hose to drain automatically and continuously. Once connected to the app, it's straightforward to operate and you can even set up multiple devices to run at the same time by using AI-enabled speakers.
Altogether, this is an impressive and powerful dehumidifier that can efficiently handle any room.

Best budget
Despite its name, Dan's tests found that this compact appliance can hold about 24 pints of water, although this is still relatively small compared to others on the list. Ultimately, this dehumidifier has a very user-friendly design which couldn't be more compact to store.
Dan found that this is a standout for storage. This dehumidifier can be ‘nested’ into itself so it takes up half of the space, so it's perfect for small basements, laundry rooms, or home offices.
This dehumidifier is easy to use, too. Once connected to its app, you can monitor it from your phone, including viewing the humidity levels and receiving alerts when the bucket is full. Dan's tests showed that you can change the settings remotely too, adjusting the speed of the fan with three levels to choose from. On top of that, you can control it with your voice via Alexa or Google Assistant.
It's just as quiet as the Honeywell dehumidifier above, but one drawback is that it makes a slightly irritating noise similar to an air conditioner.
It's slower than the Honeywell dehumidifier but it gets the job done and proves to be a useful asset when dealing with a damp basement. It’s also incredibly easy to empty, as the lower half turns into a bucket and handle.
All in all, this is a simple, budget-friendly, effective dehumidifier.

Best for flooding
Dan put the dehumidifier to the test in an extremely humid basement bathroom and laundry room. While other dehumidifiers of this size and stature generally take about 45 minutes to an hour to get the humidity level down to 35%, the GoveeLife Dehumidifier brought the humidity down to 35% in just 34 minutes.
Similarly, the dehumidifier performed well in a large space (about 700 square feet), taking just 10 minutes for the humidity level in the room to drop 10%.
Dan found the app simple, intuitive, and fuss-free. You can control the dehumidifier from other rooms in the house, and the app works with Google and Alexa too, so if you want to set up those features, you can even control the dehumidifier from outside your home.
Despite its impressive power, there were a few downsides. Unlike the Honeywell dehumidifier, this is a very noisy machine, which can be irritating, especially if you work from home. Dan also found that it throws off a good bit of heat, which is fine in cool spaces and in winter but could make smaller spaces or areas very warm.
However, if you simply want a powerful and intuitive dehumidifier that can quickly extremely damp basements or large spaces, the GoveeLife Smart 50 Pint Dehumidifier is Dan's top choice.

Best for large spaces
If you're after a dehumidifier to handle a big room, the Frigidaire 50 Pint will get the job done.
Dan put it to work on the largest most humid room in the house: the basement. With a size of around 1,000 square feet, the initial humidity level was around 50% to start. Dan was impressed that the Frigidaire dehumidifier got the humidity level to 35% in just 20 minutes. In fact, all of the humidity measurements on the unit matched up almost perfectly with Dan's Alexa air quality monitor.
Dan ran the same tests in the basement bathroom, and the Frigidaire 50 Pint Dehumidifier was able to bring down humidity levels from 90% to 35% in just forty minutes, which is faster than other dehumidifiers Dan tested.
The only downsides Dan noted are its size, hefty weight (it's 41 pounds), and noise levels. If you're after handy smart features, this isn't for you, because it doesn't have an app. Unlike the dehumidifiers above, you can't operate this appliance from your phone. If you need something smart, you need the Midea or GoveeLife dehumidifiers above.
However, it's simple to operate, and it pulls a lot of moisture very quickly. It's all you really need to handle extremely damp basements or spaces.

Best for energy efficiency
The Amazon Basics 35-Pint dehumidifier may be basic, but Dan was impressed. He particularly liked its performance in midsized rooms with high levels of dampness.
Dan found that it worked quickly and efficiently to control humidity in spaces up to which measures about 900 square feet. However, it was overkill for any space under 600 feet or so, and threw out a lot of heat.
Despite its 35-pint capacity, it is quite large and heavy to lift. Luckily, the unit is mounted on casters, which makes it easy to move around on the floor. Its six-liter bucket also slides out easily from the front of the unit and includes a handle to make it easy to empty.
Like the Frigidaire above it doesn't come with an app, but the buttons on the top of the unit allow you to power it on, make the adjustments you’ll need and are straightforward to use.
Another downside is it was the noisiest of the all the models Dan tested. It reaches a whopping 70 decibels, so you can't run it while you work from home. However, it consistently and quickly removed humidity in large, damp spaces.

First, Dan researched the top picks that are currently on the market to determine the best dehumidifiers on the market. This included top-selling and highly reviewed machines on popular retailers like Amazon, Best Buy and The Home Depot.
The chosen selection of dehumidifiers were then subjected to hands-on, extensive testing in the same environment. Dan spent weeks testing these dehumidifiers in damp environments like their basement, kitchen and other areas that were prone to high levels of humidity.
To evaluate how well the dehumidifier works for every situation and space, Dan looked at the following things:
Set up and ease of use:
Dan looked at how easy it was to set up the dehumidifier in your space. How heavy is it move around? How many pints does it have? And does it have useful features such as wheels or a carry handle at the top for better portability? He even looked at the length of the power cable and whether it would be convenient for many households.
Dan also considered how easy it was to maintain the dehumidifier and to empty out the water bucket. If the model had an included drain hose or built-in pumps, Dan looked at how efficient it was when draining moisture into sinks. In addition, how easy is it to clean afterwards and replace the filter.
Design and features:
Dan analyzed the overall design and whether its size was suitable for the space. He then looked at notable features such as LCD display , touch screen controls or remote control. Dan considered whether it had settings like an auto-off feature, timer, frost control sensor, and auto-restart, and evaluated smart or app capabilities such as voice control. What's more, Dan noted if the app was easy to use and intuitive, and if there were any pairing issues.
Performance and efficiency:
As part of his testing, Dan ran the hot shower/faucet for about five minutes in the bathroom, kitchen and basement to get the room up to 90% humidity. Once the dehumidifier was turned on, it was left to run for under 12 hours each day over a few weeks.
Dan then timed how long it took for the dehumidifier to reduce humidity to the level set and total runtime for the day. For instance, the Honeywell 50 Pint dehumidifier (and Dan's winner!) took less than an hour to reach 35% humidity, the fastest of all the models. Dan also recorded the daily average and total runtime for over a week. For accurate readings, Dan compared the humidity of his space with against an Amazon Alexa air quality monitor.
In addition, Dan monitored how many watts of power the dehumidifier used while it was running with the fan on high, and with the fan turned off. This helped us to determine total consumption and how energy-efficient the dehumidifier was. Other issues noted were discrepancies between the built-in humidistat readings and separate Alexa air quality monitor levels, any leakage issues, as well as noise levels.
How to buy the best dehumidifier
There are a huge range of dehumidifiers on the market. Before choosing your favorite, here are a few factors you should consider:
Type
There are different types of dehumidifiers on the market. The most common type is a condensing dehumidifier, which pulls the absorbed air over refrigerated coils, which cools it enough the condense and separate the moisture.
Other types include desiccant dehumidifiers, which will use a water-absorbing material, and thermoelectric dehumidifiers, which operate with charged plates. Generally speaking, neither of these latter two types are as effective as condenser models, which is why Dan only recommends this type in his list.
Capacity
Dehumidifiers generally come in three sizes: large (45-50-pint capacity), medium (30-pint capacity) and small (20-22-pint capacity).
Under the old regulations, these sizes were 70, 50 and 30 pints, respectively, and you'll see such numbers with three older models above.
Noise level
If you’ll be placing a dehumidifier in a quiet room, such as a bedroom or home office, where you need to fall asleep or concentrate without being disturbed, consider the noise level of the dehumidifier before you buy. Aim for a dehumidifier with a decibel level of around 50 decibels or below, anything above this level will be louder.
Features to look out for
Pint capacity — The capacity in pints relates to how much moisture the dehumidifier claims to absorb per day. The bigger the capacity, the larger and damper space it can handle.
Bucket size — Pint capacity shouldn’t be confused with bucket size however. This specification indicates how much the internal bucket can actually hold before it will need to be emptied. The larger the bucket, the less often you will need to empty it.
Drainage type — On this list you will find passive and pump drainage types. Passive types let you passively drain the water through a hose, or alternatively you can manually carry and empty the bucket yourself. Whereas pump drainage types will automatically pump the water out. Pumps are preferred as the water doesn’t need to rely on gravity alone to drain, so you can direct the hose into a sink or out of the window. However, these models do cost more than without.
Energy Star Certification — It’s always useful to look out for Energy Star Certification as this guarantees savings in terms of energy and money.
Humidity sensor — With a humidity sensor, your dehumidifier will detect relevant changes in the atmosphere and can automatically switch on and, in some cases, set its power accordingly. Those without a sensor will just be manually controlled.
Frost sensor — A frost sensor will detect the formation of ice on the condenser coils. The dehumidifier will then shut off the compressor to give the ice a chance to melt. If it continues to run with frost on the coils, this can damage the parts and make the appliance work much harder to absorb any moisture.
Auto restart — If the dehumidifier suddenly loses power, auto restart means it will automatically switch back on to its previous settings once power is restored.
Number of speeds — This relates to how many speeds the fan has on the dehumidifier. The more speeds there are, the better as it gives you greater control and means excess energy isn’t wasted.

Where is the best place to put a dehumidifier?
Ideally, a dehumidifier should be placed in the centre of a room to work efficiently. This allows the air to circulate properly around the unit.
Generally, a dehumidifier can dry out a room between 24 and 72 hours. But this depends on whether the room is large or has high humidity levels, which would take up to weeks to dry out.
