High humidity levels create an environment for mold and mildew to thrive, so a dehumidifier is a wise investment if you live in a humid climate. 

Our testers used dehumidifiers from the top brands in their homes for two weeks, evaluating ease of setup, effectiveness, design, and additional features. Our best overall pick, the HomeLabs Energy Star Dehumidifier, is easy to use and maintain, has a large coverage area, and is sleek and compact. 

Here are the best dehumidifiers.

Final Verdict

Our top pick is the hOmelabs 70-Pint Dehumidifier, a model that will really go above and beyond in de-humidifying your space. After running it in her basement for 7,500+ continuous hours, our tester found it to be well-designed, easy to maneuver, and overall very effective. If you’re looking for a more compact option, we recommend the Tenergy Sorbi 1000ml Air Dehumidifier and Air Purifier. Its sleek design and 2-in-1 functionality earned it a perfect 5/5 from our tester.

It’s hard to really get a sense of a product without using it in person, which is why we prioritize thoroughly testing products before recommending them to you. For this roundup, our testers put the dehumidifiers to use in the dampest areas of their homes (think: musty basements, soggy bathrooms) for 2+ weeks. During this time, they noted how effective each option was at collecting water, along with the ease of setup, usefulness of features, and overall design. After judging each dehumidifier on these individual attributes, we compiled all of our data into one overall score. We then combined their testing results with our writers’ and editors’ own research to bring you this list.

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.

With the exception of mini dehumidifiers, there is often not much of a size difference between models capable of removing more pints per day versus units with more limited moisture-removing capacities.

Water tank

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.


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 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.

Electronic controls

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 (this is called an auto-humidistat). The advantage to a model equipped with electronic controls can be a lower electric bill, along with easier operation.


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.

  • Dehumidifiers usually use a compressor or desiccant rotor to condense moisture from the air. They pull warm, moist air into the machine from one side and cool it against coils containing a liquid coolant. The moisture is then condensed out of the air and dry air is sent back into the room through the other side of the machine. The moisture that is collected from the air drips into a collecting tray. When the collecting tray is full, the machine will usually turn off and indicate to you that it needs emptying.

  • There are a number of factors to consider when choosing a dehumidifier. You will need to consider the size of the room you would like to put it in, how many pints of water the dehumidifier removes per day, the level of humidity in your area (or the room you’d like to put it in), and the temperature of the room overall. Knowing the square footage of the room can provide a good estimate of what size you will need. Small, portable dehumidifiers work well for smaller spaces as they remove around 13 or 14 ounces of water per day. If you’re wanting to cover a larger room, you’ll want to go for a unit that removes around 50 or 70 pints per day. Whole house units are also available and can remove up to 95 pints of water per day.

    Temperature is another important factor to consider. If you live in a very humid climate, or the room you’d like to put your dehumidifier in (like a basement) has higher levels of moisture, a standard machine may not work as well. You’ll then want to look for a high-capacity unit built to function more often than a standard machine.

  • Since dehumidifiers suck moisture out of the air, they can indirectly help keep a room cooler. Heat thrives in moist and humid environments, so when removed, cooling a room down becomes much easier. A dehumidifier won’t directly cool the air itself, but it can still help keep temperatures at a more comfortable level by removing excess moisture in the air. It can be helpful to use in tandem with other cooling devices like a fan, but it won’t give you the same results as an air conditioning unit.

  • Keep your dehumidifier in good working order with a regular schedule of cleaning and maintenance. Of course, you’ll need to regularly empty the water tank, unless you have a continuous drain system in place. But to really make sure that your dehumidifier is capable of peak performance, you’ll want to also regularly clean and replace the air filters.

    Most dehumidifier models have a simple filter to block large particles of dust and debris from entering the unit. These filters are often washable and a quick rinse with cool water is usually enough to clear the filter of accumulated particles, but you may need to use soap and rinse thoroughly if the filter is extra dirty. However, it’s also important to follow the manufacturer’s recommendations for filter replacement to make sure that this first line of defense against dust, pollens, and allergens is able to do its job.

    Another important step in cleaning your dehumidifier is to regularly wash and sanitize the water tank. The damp, warm environment where moisture collects can become a safe haven for bacteria or mildew to develop. Keep things fresh and clean by regularly emptying the water tank as mentioned above and never letting the stagnant water sit for an extended period.

    Additionally, it’s recommended to give your water tank a soapy scrub every few weeks to make sure that the tank stays sanitary. When you’re cleaning the tank, check to see if your model has a basket filter (a smaller filter inside the water tank). If so, make sure you rinse that smaller filter too.
