Having a stuffy or musty home is every homeowner's or renter's nightmare. Not only is it uncomfortable, but it could lead to mold, mildew, and odors. While we can't lessen our water usage from doing the laundry, cooking, showering, or using the dishwasher, we can control the humidity levels in our home through a dehumidifier. Using one avoids condensation build-up during winter and decreases the hot and sticky feeling in summer.
Now, it may seem like there's a lot of science (and math) involved in getting a dehumidifier, with the need to take humidity levels and room size into account. But we've gone and done most of the work for you! We've picked out the best dehumidifiers online and compiled a list as well as a buying guide to help you select the right dehumidifier for your home. Our favorite is Waykar's 2,000 Square-Foot Dehumidifier, which is super customizable and great for large spaces.

It is the task of a dehumidifier to maintain healthy and balanced humidity levels in a room by removing any excess moisture in the air. They work much like your typical air conditioner wherein moist air is drawn in by the dehumidifier's fan and condenses as it passes through its cooled coils.
The condensed moisture drips from the coils into a basin or it could be pumped out to a drain. Drier air is then released back into the room.
It's important to choose a dehumidifier that fits your needs and expectations, such as which room you want to lower humidity levels in and your ability to drain the collected water. There are also automatic settings, filter maintenance, and temperature limit to consider.
The ideal humidity range for comfort is around 30 to 40 percent in the winter and 40 to 50 percent in the summer. Before buying a dehumidifier, check to see how humid your room is to help determine how much dehumidifying power you need. You can use a humidity meter or look for certain clues.
A slightly damp room between 50 and 60 percent isn't super noticeable, but the air may feel heavy, especially in humid weather. Rooms that are mildly damp will require minimal levels of dehumidifying.
Moderately damp rooms with 60 to 70 percent humidity may have an occasional musty odor. In addition, the air might feel damp and clammy depending on the weather. These rooms will need a slightly more powerful machine.
Spaces that are between 70 and 100 percent humidity will have condensation on the walls, floor, or ceiling. They may also have water seepage, standing water, and mold issues. These areas, often basements and laundry rooms, will need heavy-duty dehumidifiers.
Once you know how humid your room is, you'll want to measure your room to determine its size. Dehumidifiers are rated by the amount of moisture in pints they remove in 24 hours, so you should find a balance between the humidity level and size of your room.
Small rooms or areas such as a closet or kitchen cupboard do not require heavy-duty dehumidifiers. For periodic and localized humidity issues, portable or mini dehumidifiers are a popular choice among homeowners. These typically have a capacity of 10 pints or less.
They are often plug-and-play and quite light on the wallet. They use up less electricity and can fit easily into small spaces.
Medium-sized rooms within the range of 300 to 500 square feet require more capable dehumidifiers, If your room has a 50 to 70 percent humidity level, a dehumidifier with a 20 to 30-pint capacity is recommended. If humidity levels reach 80 to 100 percent, it's best to increase pint capacity to 40.
Rooms ranging from 500 to 1,500 square feet that are moderately damp can usually get away with a 30 to 40-pint capacity. If your room is wet, however, look for a dehumidifier with a capacity of 50 to 60 pints.
Dehumidifiers with a high capacity of 70 or more pints are ideal for large spaces between 1,500 and 2,500 square feet. They work well for very damp and wet areas as well as multiple adjacent rooms with humidity problems.
If you experience high humidity all year round and in more than one room, you may want to opt for a centralized whole-house dehumidifier instead of having multiple dehumidifiers lying around. This machine uses your home's heating-and-cooling system to maintain proper humidity levels across all rooms of the house.
As mentioned earlier, there's more to choosing dehumidifiers than room size and pint capacity. Other factors like climate and number of occupants affect your selection process.
Automatically add 10 pints to the capacity you need if you live in a place with a more humid climate. These climates are characterized by hot and humid summers and cold to mild winters.
More people living in a particular space means more humidity creation through the various activities we engage in such as showering, cooking, or doing the laundry. Another five pints is advised.
Add five more pints if you have multiple windows, doors, or other surfaces hit by opposing outdoor weather, which leads to condensation and extra moisture buildup in the air.
Washers and dryers are examples of household appliances that produce extra moisture. It's recommended to add five pints if a dehumidifier is going to be placed near these types of machines.
Cleanup and maintenance are other factors to consider when picking a dehumidifier because manually removing the basin with collected water and draining it at the sink can be quite a hassle.
If you're placing the dehumidifier in a slightly damp room that experiences extra humidity periodically, getting one with an internal bucket might not be such a bad idea since it might take a few days before it's filled. Go for dehumidifiers with larger tubs so that you need to take fewer water collection trips.
It might be unsightly, but a dehumidifier with an internal pump that directs the water collected up a hose and into a sink saves you the obligation of having to empty the basin regularly, especially if you're dealing with higher humidity.
A dehumidifier with a drainage hole can be placed over a floor-level drain so that all the water being collected can be disposed of without effort. In most cases, a hose can also be connected to direct the water to a drain.
Energy performance is another thing to consider when choosing a dehumidifier. Your humidity problem might get fixed but at a high expense because of its energy consumption.
It's important to note that getting a dehumidifier with a capacity bigger than your requirements is a better option than an undersized model, which will work overtime to maintain the right humidity levels, thus consuming more energy in the process.
The Energy Star rating is the best way to gauge a machine's energy efficiency. It is an international designation that indicates that the product has passed a standard of effectively doing its job without consuming too much energy.
Hats off to technology for allowing so many advancements in our machines that we don't need to exert extra effort maintaining them! Dehumidifiers can have perks like sensors and automatic settings which make them even more convenient to use.
Most dehumidifiers today have indicators that inform you when the water basin needs draining or the filter requires washing or replacing. As we go about our busy lives, we rely on reminders like blinking light indicators to avoid any accidents or damage to the equipment.
More high-end dehumidifiers also have useful automatic settings like shutting off when the right humidity level is reached and turning back on when needed, or automatically defrosting a unit if it reaches low temperatures to avoid damaging its coils.
Such features save you big bucks on the electricity bill and having to replace parts during the winter season. There are also some models with an auto-reset feature, which restores the dehumidifier to its previous settings in case of a power interruption.

The Whole-Home Dehumidifier That Only Needs One-Time Setting
This reliable dehumidifier can handle any room with different humidity levels such as a basement, bathroom, bedroom, laundry room, or cellar. Adjust the humidity from 30 to 85 percent and then the machine will automatically shut off and turn on to maintain that level.
It features a 2.5-liter water tank as well as a drain hose so you can choose your emptying method. The fan speed is adjustable and the air outlet can be rotated to point towards a specific area. And despite its size, it's easy to move, with 360-degree rotatable wheels on the bottom and a handle that pops out of the top.
Some reviewers mention that the capacity may be overstated, saying that it needs to be emptied quite often and isn't very effective in 2,000 square foot spaces. Still, many reviewers liked how compact and quiet it is and said it made a noticeable difference in the humidity level inside their home.
This dehumidifier is equipped with all the settings and features you might want. Use the touch panel controls to set your ideal humidity level, then let it run its continuous 24-hour cycle. Once the tank is full, it will shut off automatically. Alternately, it has an outlet to connect a drain hose, which needs to be purchased separately.
It has a large 1.8-gallon water tank, which can remove up to 50 pints of water per day, but its Energy Star rating promises you cost efficiency as well. This dehumidifier is ideal for extra-large rooms up to 4,500 square feet as well as very wet spaces.
Those that prefer silent dehumidifiers should be aware of this machine's audible hum that some reviewers likened to an oscillating fan. Others warned that it has a short life. Still, the majority of reviewers said it's super effective at removing moisture from the air. Many used it in their basement with great results.
This portable dehumidifier only needs one button to function and will continue absorbing excess moisture in the air until it reaches full capacity, when it will then turn off and alert you of a full basin. It can quietly remove up to 1.5 pints of moisture in small spaces per day.
This dehumidifier uses no compressor so it operates at a quiet level below 39 decibels, making it ideal for small spaces. It measures 14 inches tall and weighs just under six pounds, so you can easily move it from place to place. The temperature for optimal results is 59 to 86 degrees Fahrenheit.
Reviewers noted that this machine works best in small spaces and can be quite slow to remove moisture in larger rooms. In general, people who were shopping for a small dehumidifier loved this one. They liked its compact size and quiet fan and found it to be quite effective.
This dehumidifier from Midea is packed full of useful features. It works for spaces up to 1,500 square feet and can remove 20 pints of moisture per day.

The dehumidifier has an auto-restart function in case of a power outage, as well as an auto-defrost to prevent the water from freezing. The air filter is washable so you can easily maintain the air quality. And at a maximum noise level of 51 decibels, it's about the same level as a quiet conversation.

This dehumidifier is so small and inconspicuous you won't even know it's there, quietly absorbing extra moisture in small spaces like your closet, gun safe, gym bag, or even the car. What's more, you don't need electricity or batteries to run it.
Its secret is non-toxic crystallized silica gels which suck in moisture from the air. The indicator will turn from orange to green to let you know that it's time to recharge the unit by plugging in the device, which heats up and dries out the gels.
Some reviewers said this dehumidifier doesn't last very long, while others were worried about how warm it gets while charging. However, most reviewers liked how straightforward and simple it is to use. They said it's perfect for small spaces with lower humidity like RVs, trucks, and safes.
This is your go-to dehumidifier for medium to large spaces. Not only does this machine work well in cleaning and dehumidifying the air, but it also looks good while on the task. The sleek, clean design comes with wheels and handles, so you can easily transfer the unit to a different room.
It has a memory feature that remembers the last setting in case of power interruption and an auto-defrost feature, making it able to withstand colder environments. If you prefer to avoid having to empty the water tank, it also has a drain hose outlet, to which you can connect a separately purchased hose.
If you're interested in this particular model, reviewers recommend being prepared for noise. Some said they could hear this dehumidifier from the next room over. However, many said it's a great option for basements since it has a large reservoir. They were pleased with its effectiveness, especially in wet spaces.
At just over 12 inches tall, this dehumidifier is compact and portable, making it ideal for small spaces up to 250 square feet. It features an auto shut-off with an LED light that indicates when the water tank needs emptying. The tank itself slides out easily from the front of the machine.

This dehumidifier is also equipped with all the automatic features a high-end unit typically possesses such as auto-off, restart, and defrost settings.
Some reviewers said this dehumidifier has a short life, and experienced issues with the humidity sensor, control panel, or defrost function. A few were able to get replacements from the manufacturer. Other reviewers were pleased with how quiet it is and liked that it has a timer to help save electricity.
This little dehumidifier measures just nine inches high and six inches wide, so it's super compact and great for small spaces. It can remove up to one pint of moisture per day in rooms up to 260 square feet. The one-touch design is easy to use and the machine will automatically shut off when the water tank is almost full.
It's designed to be quiet and efficient, using just 40 watts per hour. And it also has LED lights in seven different colors that you can use to light up your room. Pick a single color or set it to switch between them. This dehumidifier would be ideal for a bedroom.
Some reviewers warned that the plug gets hot when the dehumidifier is working. Others said it's not very effective at removing moisture. On the other hand, many reviewers said it worked well in their small space, including bedrooms and bathrooms. And they especially enjoyed the colorful lights!
If humidity stays at high levels all year round, it might be worth it to invest in a whole-house dehumidifier. Simply set it up near a drain (or attach a hose to a drain), level and plug it in, choose a target humidity, and forget about the dehumidifier.
The beauty of this machine is it will address the humidity issues all over your home and prevent your carpets and furniture from getting damp, protect your walls and tight spaces from growing mold and mildew, and keep your air clean and fresh.
Some reviewers warned that the warranty only applies if you pay for installation and found the customer support to be lacking.
