Dehumidifier

Beyond just making you feel sweaty, high humidity levels can also aggravate your allergies and asthma symptoms, as well as create an environment where mold can grow around your home. Niha Qamar, MD, an author and board-certified allergist and immunologist in New York state, explains that excess moisture and humidity “will cause certain allergens (such as dust mites and mold) to proliferate in the home and increase the level of these allergens.”

Reviewed & Approved

We chose the Frigidaire High Efficiency Dehumidifier as the best overall pick because it is efficient and has a large water reservoir, so it’s great for spaces that are a variety of sizes. The Eva-Dry Electric Petite Dehumidifier is a budget-friendly pick that also helps remove allergens effectively.

Dr. Qamar says that dehumidifiers can help since they’re made to take in humid air, extract some of its moisture, and return drier air back into the room. When shopping for a dehumidifier, take the type of allergies you’re experiencing into account, along with the size of the room that the device will occupy. Additionally, keep in mind that some devices can be noisy, which may be important for anyone planning to use the dehumidifier in their bedroom.

We researched many dehumidifiers and compared their ability to handle different-sized rooms, reservoir size, noise levels, portability, and price. Each of the dehumidifiers chosen were determined to be the best of these factors.

Here are the best dehumidifiers on the market today.

What do buyers say? 9,900+ Wayfair reviewers rated this product 4 stars or above.

When choosing a dehumidifier for your home, it’s important to consider the size of the reservoir and the recommended room size that it can manage, especially if you have a large room. That's why we recommend the Frigidaire High Efficiency Dehumidifier, which can hold up to 50 pints of water and covers medium to large-sized bedrooms. The water reservoir even has a handle and splash guard to help make dumping even easier. Plus, if you have access to a drain, this dehumidifier can be set up to empty right into a drain—meaning you won’t need to worry and dumping out the water ever again.

While this humidifier is on the heavier side, weighing 44 pounds, it comes with wheeled casters and lift handles, so you can take it from room to room. It also features an automatic shut-off feature in case the reservoir gets too full as well as humidity controls so you can get the room just the way you like it.

Best Budget: Eva-Dry Electric Petite Dehumidifier

Pros
  • Runs very quietly and uses minimal power

  • Lightweight and portable

Cons
  • No filter

  • Small reservoir requires frequent change

A large, heavy-duty dehumidifier can be great for big rooms, but if you’re looking to save some money (and some extra cash on your energy bill), then a smaller dehumidifier is definitely worth considering. The Eva-Dry Electric Petite Dehumidifier is very quiet, cost-effective, and can run continuously on 22 watts of power. 

It’s also portable, weighing only 3.5 lbs, and it can hold two cups of water. The water reservoir is clear, so you can check the level at a glance, and an LED light on the front of the dehumidifier will also tell you when the reservoir is full. A dehumidifier of this size is perfect for small office cubicles, musty closets, or humid laundry rooms.

Reservoir Size: 1 pint | Charge Type: Electrical charge | Number of Filters Included: No filter needed

Best for Allergies: Ivation Small-Area Compact Dehumidifier

Ivation Small-Area Compact Dehumidifier

Home Depot

Pros
  • Programmable humidistat

  • Runs on low voltage and is very quiet

  • Lightweight and portable

Cons
  • Not the best option for large rooms

  • May not last as long as other dehumidifiers

This small-but-mighty dehumidifier works fast to pull over four pints of moisture out of the air. It is compact in size—measuring 17 inches and weighing under 11 pounds—so it is ideal for spaces like tight crawlspaces and small rooms. It features a digital readout so you can set the humidity just right, as well as an LED power “on” light and a reservoir “full” indicator light. 

The water reservoir can hold over six pints, meaning it needs to be emptied every day and a half (when running at full capacity). But if you have the correct type of plumbing in your home, you can use the drainage pump that will self-empty all collected moisture down the drain.

Reservoir Size: 6.3 pints | Charge Type: Electric charge | Number of Filters Included: 1 washable filter

Best for Dry Skin: Waykar Dehumidifier

Pros
  • 360 degrees swivel wheels for easy transport

  • Variety of programming options

Cons
  • Heavy

  • May not cover large, open spaces

If you have dry skin, a strong dehumidifier can remove too much moisture from the air and make dry skin symptoms even worse. That’s why a humidifier that is intuitive and programmable is a must to make sure you don’t dry out your room too much. This Waykar Dehumidifier not only lets you set the digital humidistat, but you can also program the timer for automatic shut-offs, customize your use options, and change the fan speeds. 

This humidifier covers 2000 square feet and can daily pull about 34 pints of moisture out of the air that can either be drained from the 2.5-liter capacity reservoir (complete with a “full” indicator LED light on the front of the dehumidifier) or can be auto-drained with the included 6.5-foot hose.

Reservoir Size: 2.5 liters | Charge Type: Electrical charge | Number of Filters Included: 1 washable filter

Pros
  • Lightweight and very portable

  • Can cover 250 square feet

  • Whisper-quiet operation

Cons
  • Doesn’t work properly under 41 degrees

  • No filter option

A small, portable dehumidifier can be a great option for bedrooms and getting your room’s humidity just right while you sleep. This Pro Breeze Electric Mini Dehumidifier can remove about one pint of moisture from the air throughout the day, and it stores that moisture in a removable 3-pint capacity reservoir. It’s built for bedrooms because it can cover spaces up to 250 square feet.

Using thermo-electric cooling, this dehumidifier doesn’t use a compressor. As a result, it runs almost silently. There are also two easy-to-read LED lights on the top of the dehumidifier that tell you when the unit is turned on and when the water reservoir is full. And if you aren’t able to drain the reservoir in time, this humidifier features an automatic shut-off feature that turns the entire unit off when the water level gets too high.

  • Can cover 4,500 square feet

  • Built-in compressor helps remove moisture

Cons
  • Heavy

  • Users might still see a significant spike in their energy bill from long-term use

  • Drainage hose not included

While most of the dehumidifiers on this list are meant for single rooms or small spaces, this hOmeLabs Energy Star Dehumidifier can maintain humidity in spaces up to 4,500 square feet. It can also help dry out wet or damp areas that may have had a pipe burst or water leak that needs to dry up quickly.

The dehumidifier sits on four-wheeled casters and can easily be rolled from room to room. It has a 1.8-gallon reservoir that can remove about 50 pints of moisture per day. It can also run continuously (it has a programmable 24-hour cycle, too) until the reservoir is filled and shuts itself off or when the job is done. This dehumidifier can also be hooked up to a drain so water can empty out easily—just make sure to pick up a drainage hose because it’s not included. 

Even despite its heavy-duty design and overall power, this dehumidifier is Energy Star certified.

Pros
  • Runs as quietly as most household appliances

  • Can cover 3000+ square feet

  • Can attach common garden hose for drainage

Cons
  • Amount of moisture removed can vary based on temperature

  • No drainage hose included

One of the biggest benefits of the TOSOT Energy Star Dehumidifier is that it runs almost silently, making it ideal for bedrooms. It is also an Energy Star rated dehumidifier that helps bring down electricity usage—and costs—compared to other brands. 

With a 2-gallon reservoir and easy-to-program buttons, and digital readouts on top of the dehumidifier, you can remove approximately 50 pints of moisture a day from the air. Smaller models are also available at a lower price that can remove 20 or 35 pints per day.

If you forget to dump the reservoir, there is a built-in shutdown feature that turns the dehumidifier off if the water level gets too high. You can also attach a typical 3/4 inch garden hose to the unit for constant drainage while in use—no need to hunt down a brand-specific hose or size.

Best with Large Reservoir: Midea Cube 50 Pint Dehumidifier

Midea Cube 50 Pint Dehumidifier

Amazon

Pros
  • Unique cube design allows for larger capacity

  • Can collapse down to smaller, more portable size

  • Easy to dump excess water

Cons
  • Filter can be hard to remove for cleaning

  • Heavy

Of all the dehumidifiers on our list, Midea Cube Dehumidifier has one of the largest capacity reservoirs. This cube-shaped dehumidifier sits inside a larger outer shell that can be used in its tight, compacted position. Or, it can be lifted up to the top of the outer shell to create an expanded reservoir that holds over four gallons of water. There is also the option to attach the reservoir to a drainage hose, or the entire unit could be placed over a bathroom drain or in the sink to let the water drain out on its own.

This model is able to remove approximately 50 pints a day, and 35-pint and 20-pint models are available as well at a lower price. It can also be paired with your smartphone, so you can ask Alexa or Google to adjust your settings or send you alerts if the reservoir gets full.

Wayfair

Pros
  • Pulls moisture out of the air quickly

  • Drainage hose included

  • Reservoir can be removed and replaced easily

  • Relatively small water reservoir

  • Not the best option for larger spaces

If you’re looking for a dehumidifier that can do the job quickly, this Yaufey Dehumidifier might be a great fit.

This dehumidifier can cover a 1,500-square-foot room and is very lightweight (under 24 pounds), and features four wheels and a handle for better mobility. So, if you’re looking to bring the humidity down quickly, set this one up in a small room or basement, shut the door, and let it get to work.

While the reservoir can only hold about 1.8 liters—meaning that you will have to change it every day—it comes with a 2-meter long drainage hose.

Reservoir Size: 1.8 liters | Charge Type: Electrical charge | Number of Filters Included: 1 washable filter

Final Verdict

We chose the Frigidaire High-Efficiency Dehumidifier as our best overall pick because it covers medium to large rooms and features a larger tank and washable filter. But if you’re looking to improve the air in a smaller space at a price that’s more friendly to your budget, the compact Pro Breeze Electric Mini Dehumidifier is a great choice for more targeted areas.

How We Selected the Dehumidifiers

When selecting dehumidifiers, we spoke with allergists and spent hours combing the web for the best and most effective products. After taking all of our options into consideration, we determined which to feature based on a few key criteria: reservoir size, portability, auto-off features, and programmability.

Once we narrowed down our options, we compared each dehumidifier’s benefits to its price tag. While some choices on our list may be more expensive, we wanted to give a wide range of options that would fit all needs and budgets. Based on all of these factors, we compiled this list of the best dehumidifiers.

What to Look for in a Dehumidifier

Humidity Level

If your home or office is particularly humid, you run the risk of creating an environment where mold and other allergens can grow. “A dehumidifier can remove moisture from the environment,” says Kanao Otsu, MD, an allergist, and immunologist at National Jewish Health in Denver. “This may be helpful for individuals who have mold or house dust mite allergies who live in a humid/moist environment.” 

All dehumidifiers will list how much moisture they can remove from the air in a single day. This is often listed in pints or ounces. If a dehumidifier can remove a large volume of moisture on a given day, your air will be far less humid and less likely to grow mold, explains Dr. Otsu.

Space

The space you plan to dehumidify will be a major factor in your shopping decision. In the same way that you wouldn’t need a massive dehumidifier for your bathroom, a smaller dehumidifier wouldn’t be able to significantly change the humidity of a large room. 

That’s why it is important to get a dehumidifier that matches the room so that you don’t create humid areas that your dehumidifier can’t reach. “Mold or fungi require moisture for optimal growth,” says Dr. Qamar. “You can eliminate mold by eliminating sources of moisture.”

Before making your purchase, measure or estimate the square footage of the room you plan to use the dehumidifier in. Each dehumidifier on this list shares its recommended square footage, which will help you buy the best one for your needs.

Programmable Humidistat

Similar to your home’s thermostat that tracks the temperature in your home, a humidistat can track the humidity (measured as a percentage out of 100) in a room and can make adjustments as needed. Less expensive models often don’t come with a humidistat, meaning you will need to buy one separately if you want to track the humidity, and you will need to manually turn the dehumidifier on and off as needed. 

“If you have allergies to dust mites and mold,” explains Dr. Qamar, “decreasing the humidity to less than 50 percent can significantly improve your allergies.” So, if you want to take the guesswork out of your room’s humidity levels, a dehumidifier with a programmable humidistat might be the best way to go. You can easily set it at around 50 percent (or to whatever’s comfortable for you) and leave it alone, knowing that it will turn on and off to stay at your preset percentage.

Reservoir Capacity

“A humidifier will add moisture to the air while a dehumidifier will remove moisture from the air,” says Dr. Qamar–which is why reservoir capacity is so important when ultimately choosing a dehumidifier. With all that extra collected moisture, how often do you realistically think you will be able—or willing—to dump the collected water? 

Some reservoirs are very small and can only hold a few pints, while others can hold gallons of water, meaning that you can go longer between removals. Some models also come with a drainage house too that lets you hook up a hose that you can run into a drain or sink so that the collected water can be removed just as soon as it’s collected.

Frequently Asked Questions

  • What does a dehumidifier do?

    A dehumidifier can be set up in an indoor area where the humidity percentage is very high. “Dehumidifiers remove the excess moisture in the air,” says Dr. Qamar. Dehumidifiers also help keep your environment dry and help prevent mold growth. If you are finding that your summer days are uncomfortably humid inside, or you’re noting more frequent allergic reactions, it may be worth looking into purchasing a dehumidifier.

  • When should you use a dehumidifier?

    If you’re finding that your home or office is becoming uncomfortable during the summer or other periods of high humidity, it’s a good time to purchase a dehumidifier. In addition to comfort, a dehumidifier can help slow the growth of mold and other allergens.

    “Certain mold thrives in high humidity,” says Dr. Otsu. “Removing the moisture can decrease mold growth.” So if you’re worried about mold growth in your home—or worse yet, start to see it growing in high humidity rooms like the bathroom—you should consider using a dehumidifier.

  • What is the difference between a humidifier and a dehumidifier?

    Both work to adjust the humidity in a room by adding or removing moisture in the air. “Humidifiers increase ambient humidity whereas a dehumidifier removes moisture from the air,” explains Dr. Otsu.

    If your home is especially dry (like during the winter) or is too humid for your comfort (like during the summer), it’s worth purchasing the right device so you can adjust the humidity to your liking all season long.

  • Will a dehumidifier kill mold?

    Mold that has already started to grow won’t necessarily be killed off by a dehumidifier, but a dehumidifier can help slow the spread of mold and prevent mold from starting to grow in the first place. 

    “Keeping humidity below 50% with a dehumidifier can eliminate mold,” explains Dr. Qamar, “if you can also remove any other sources of condensation (such as water leaks from pipes, removal of any standing water, and dampness in the basement or crawlspace).”

    In addition, you should clean your dehumidifier’s filter regularly. This will help prevent mold or mildew growth, especially if the filter gets clogged or is overused.
