As we move through the seasons and all of the unpredictable weather they bring (depending on where you live, of course), one of the problems that arise most often is dampness and moisture from the air, which causes its fair share of issues for the home. But with the best dehumidifier in your arsenal, you can wave goodbye to the headache of condensation, mold, and resulting bacteria.
Dehumidifiers work by directly removing the moisture from the air and converting it into water that you can easily dispose of. Most have sensors that can determine the moisture levels in your home and power on and off accordingly, saving energy. The best dehumidifiers even help out in unexpected areas of life, like making laundry-drying time much faster, or purifying the air in a space.
There are two types of dehumidifier that you will need to choose between - desiccant and refrigerant. Desiccant dehumidifiers use a material that absorbs moisture and condenses it, while refrigerant dehumidifiers have a cool metal plate that converts the air into liquid as it works. While the former is capable of working in colder temperatures, it also uses more energy.
We've taken a look at the best dehumidifiers that you can buy right now, ranking them based on capacity, design, and any additional features that might make parting with your cash more worthwhile. And, if you're interested in improving the air quality in your home even more, then take a look at our guide to the best air purifiers.

The best dehumidifiers in 2022
Perfect for smaller spaces like laundry rooms, the Pro Breeze Electric Dehumidifier is a compact option that works best in areas up to 215 sq ft. Despite its size, the machine will collect around 9oz of moisture per day, making it more than capable of pleasing occasional users.
When the 16oz water tank is full, the dehumidifier will automatically shut off, and the design makes it super simple to remove the tank and empty it. The only caveat is that - as with a lot of mini dehumidifiers - it won't work in cold temperatures below 41 degrees, so it might not be the best choice for those living in colder parts of the country.
With hidden wheels and pocket handles, the GE 35-pint portable dehumidifier is ideal for anyone who needs a machine that will work in different environments. This portability, plus the large extraction rate and humidistat, also make it our choice for the best RV dehumidifier.
The digital LED controls on the GE dehumidifier make it easy to work with, and there is a drain hose connection if you want to operate it continuously. Set the humidistat to your desired level, and it will shut off automatically when the 8.4-pint tank is full. You can also set the timer if you only want the dehumidifier running for a certain amount of time.
All of this and it still manages to be Energy Star certified, meaning it's designed to waste less energy than other dehumidifiers.
As the dehumidifier on this list that is capable of keeping air moisture at a comfortable level in areas up to 2,000 sqft, we would recommend the Insignia 35-pint dehumidifier for basements or crawl spaces where the job of keeping humidity at bay may be a bigger one.
Capable of removing up to 35 pints of moisture each day, the large 12.5-pink tank will also mean you are emptying much less often. Of course, you can also use the rear hose for continuous drainage if you prefer things to be even more low maintenance, and you can keep the levels just how you want them with the adjustable humidistat.
Despite not packing as much power as other dehumidifiers on this list, the AIRPLUS is a brilliant mid-range option for those with average-sized homes they want to take care of. Large enough to do its job in a basement or other large areas but relatively compact, it's lightweight enough to be moved around to wherever it's needed.
The dehumidifier also boasts four separate modes, including one quiet enough for night-time running, one for optimal humidity levels, and one for drying laundry. So just pop it by your damp clothes and watch it cut the time it takes from washing to putting away cut down significantly.
Specifically designed for basements and similar areas of the home, the Vacplus dehumidifier removes up to 30 pints of moisture from the air per day with four separate modes of operation, including 'rain,' 'dry' and sleep. The first sets humidity in the environment to the optimal level of 45%, while the second initiates continuous running for when you're trying to dry laundry.
The biggest plus of the Vacplus offering is its built-in humidity sensor. For those who have trouble remembering to turn their tech and devices on and off, the sensor will automatically alter the dehumidifier's mode depending on how much moisture it detects in the air.
How to choose the best dehumidifier for your home
Why do I need a dehumidifier?
Poor ventilation is the main reason for purchasing a dehumidifier. The majority of households regularly shower or bath, cool and wash clothes, all of which use a lot of hot water that creates steam. If there’s no way for the moisture to escape through windows or vents, then condensation and dampness begin to build. This is where a dehumidifier helps prevent this from happening and removes excess water from the air to help dry your clothes.
How does a dehumidifier work?
The way that dehumidifiers remove unwanted moisture from the air varies. For compressor models, the air is taken in through a filter and coils inside. The cold temperature of these coils converts the moist air into water, which is then deposited into the tank. Desiccant dehumidifiers, meanwhile, take in the moisture via an absorbent, which the machine then heats to convert into water.
Do dehumidifiers cool rooms?
Dehumidifiers do not work the same as air conditioners, which often also operate as a dehumidifier. Confused?
As stated above, compressor dehumidifiers use their interior components' temperature to operate, so it's actually beneficial for them to be put to work in warmer spaces. This means that there is more contrast between the temperature of the air and the colder temperature of the coils that the dehumidifier uses to convert moisture into water.
What type of dehumidifier should I get?
Not to be confused with a humidifier, which does the opposite of a dehumidifier and adds moisture to the air in your home, you can buy two different types of dehumidifier—first, a compressor (sometimes known as a refrigerant) or second, a desiccant. Compressors can remove a more significant amount of moisture per day and are cheaper to run, while desiccant dehumidifiers work better in colder temperatures and are often quieter. They’re also usually smaller and lighter than compressor models.
What extraction rate and tank size should I go for?
The extraction rate you’re looking for really depends on where you live and what you’re using the dehumidifier for, but in the US, you can aim for one that extracts between 1.5-4 pints a day.
The tank size of the products on our list varies. The size you need will depend on a) whether your dehumidifier will be turned on all day, b) whether you’re at home and can empty it periodically, c) what level of humidity you’re dealing with, and d) how much space you have.
Do I need a laundry mode?
If you often hang your clothes to dry around your home, opt for a dehumidifier with a dedicated laundry mode. It’ll work with the additional humidity caused by your wet clothes and reduce the time it takes for your clothes to dry. Win-win?
